PLY-2.2 is -a minor update that fixes a few bugs and adds some new capabilities. - -If you are new to PLY, here are a few highlights: - -- PLY is closely modeled after traditional lex/yacc. If you know how - to use these or similar tools in other languages, you will find - PLY to be comparable. - -- PLY provides very extensive error reporting and diagnostic - information to assist in parser construction. The original - implementation was developed for instructional purposes.

These - mirror the same functionality of lineno() and linespan(). For - example: - - def p_expr(p): - 'expr : expr PLUS expr' - p.lexpos(1) # Lexing position of left-hand-expression - p.lexpos(1) # Lexing position of PLUS - start,end = p.lexspan(3) # Lexing range of right hand expression - -11/01/06: beazley - Minor change to error handling. The recommended way to skip characters - in the input is to use t.lexer.skip() as shown here: - - def t_error(t): - print "Illegal character '%s'" % t.value[0] - t.lexer.skip(1) - - The old approach of just using t.skip(1) will still work, but won't - be documented. - -10/31/06: beazley - Discarded tokens can now be specified as simple strings instead of - functions. To do this, simply include the text "ignore_" in the - token declaration. For example: - - t_ignore_cppcomment = r'//.*' - - Previously, this had to be done with a function. For example: - - def t_ignore_cppcomment(t): - r'//.*' - pass - - If start conditions/states are being used, state names should appear - before the "ignore_" text. - -10/19/06: beazley - The Lex module now provides support for flex-style start conditions - as described at http://www.gnu.org/software/flex/manual/html_chapter/flex_11.html. - Please refer to this document to understand this change note. Refer to - the PLY documentation for PLY-specific explanation of how this works. - - To use start conditions, you first need to declare a set of states in - your lexer file: - - states = ( - ('foo','exclusive'), - ('bar','inclusive') - ) - - This serves the same role as the %s and %x specifiers in flex. - - One a state has been declared, tokens for that state can be - declared by defining rules of the form t_state_TOK. For example: - - t_PLUS = '\+' # Rule defined in INITIAL state - t_foo_NUM = '\d+' # Rule defined in foo state - t_bar_NUM = '\d+' # Rule defined in bar state - - t_foo_bar_NUM = '\d+' # Rule defined in both foo and bar - t_ANY_NUM = '\d+' # Rule defined in all states - - In addition to defining tokens for each state, the t_ignore and t_error - specifications can be customized for specific states. For example: - - t_foo_ignore = " " # Ignored characters for foo state - def t_bar_error(t): - # Handle errors in bar state - - With token rules, the following methods can be used to change states - - def t_TOKNAME(t): - t.lexer.begin('foo') # Begin state 'foo' - t.lexer.push_state('foo') # Begin state 'foo', push old state - # onto a stack - t.lexer.pop_state() # Restore previous state - t.lexer.current_state() # Returns name of current state - - These methods mirror the BEGIN(), yy_push_state(), yy_pop_state(), and - yy_top_state() functions in flex. - - The use of start states can be used as one way to write sub-lexers. - For example, the lexer or parser might instruct the lexer to start - generating a different set of tokens depending on the context. - - example/yply/ylex.py shows the use of start states to grab C/C++ - code fragments out of traditional yacc specification files. - - *** NEW FEATURE *** Suggested by Daniel Larraz with whom I also - discussed various aspects of the design. - -10/19/06: beazley - Minor change to the way in which yacc.py was reporting shift/reduce - conflicts. Although the underlying LALR(1) algorithm was correct, - PLY was under-reporting the number of conflicts compared to yacc/bison - when precedence rules were in effect. This change should make PLY - report the same number of conflicts as yacc. - -10/19/06: beazley - Modified yacc so that grammar rules could also include the '-' - character. For example: - - def p_expr_list(p): - 'expression-list : expression-list expression' - - Suggested by Oldrich Jedlicka. - -10/18/06: beazley - Attribute lexer.lexmatch added so that token rules can access the re - match object that was generated. For example: - - def t_FOO(t): - r'some regex' - m = t.lexer.lexmatch - # Do something with m - - - This may be useful if you want to access named groups specified within - the regex for a specific token. Suggested by Oldrich Jedlicka. - -10/16/06: beazley - Changed the error message that results if an illegal character - is encountered and no default error function is defined in lex. - The exception is now more informative about the actual cause of - the error. - -Version 2.1 ------------------------------- -10/02/06: beazley - The last Lexer object built by lex() can be found in lex.lexer. - The last Parser object built by yacc() can be found in yacc.parser. - -10/02/06: beazley - New example added: examples/yply - - This example uses PLY to convert Unix-yacc specification files to - PLY programs with the same grammar. This may be useful if you - want to convert a grammar from bison/yacc to use with PLY. - -10/02/06: beazley - Added support for a start symbol to be specified in the yacc - input file itself. Just do this: - - start = 'name' - - where 'name' matches some grammar rule. For example: - - def p_name(p): - 'name : A B C' - ... - - This mirrors the functionality of the yacc %start specifier. - -09/30/06: beazley - Some new examples added.: - - examples/GardenSnake : A simple indentation based language similar - to Python. Shows how you might handle - whitespace. Contributed by Andrew Dalke. - - examples/BASIC : An implementation of 1964 Dartmouth BASIC. - Contributed by Dave against his better - judgement. - -09/28/06: beazley - Minor patch to allow named groups to be used in lex regular - expression rules. For example: - - t_QSTRING = r'''(?P<quote>['"]).*?(?P=quote)''' - - Patch submitted by Adam Ring. - -09/28/06: beazley - LALR(1) is now the default parsing method. To use SLR, use - yacc.yacc(method="SLR"). Note: there is no performance impact - on parsing when using LALR(1) instead of SLR. However, constructing - the parsing tables will take a little longer. - -09/26/06: beazley - Change to line number tracking. To modify line numbers, modify - the line number of the lexer itself. For example: - - def t_NEWLINE(t): - r'\n' - t.lexer.lineno += 1 - - This modification is both cleanup and a performance optimization. - In past versions, lex was monitoring every token for changes in - the line number. This extra processing is unnecessary for a vast - majority of tokens. Thus, this new approach cleans it up a bit. - - *** POTENTIAL INCOMPATIBILITY *** - You will need to change code in your lexer that updates the line - number. For example, "t.lineno += 1" becomes "t.lexer.lineno += 1" - -09/26/06: beazley - Added the lexing position to tokens as an attribute lexpos. This - is the raw index into the input text at which a token appears. - This information can be used to compute column numbers and other - details (e.g., scan backwards from lexpos to the first newline - to get a column position). - -09/25/06: beazley - Changed the name of the __copy__() method on the Lexer class - to clone(). This is used to clone a Lexer object (e.g., if - you're running different lexers at the same time). - -09/21/06: beazley - Limitations related to the use of the re module have been eliminated. - Several users reported problems with regular expressions exceeding - more than 100 named groups. To solve this, lex.py is now capable - of automatically splitting its master regular regular expression into - smaller expressions as needed. This should, in theory, make it - possible to specify an arbitrarily large number of tokens. - -09/21/06: beazley - Improved error checking in lex.py. Rules that match the empty string - are now rejected (otherwise they cause the lexer to enter an infinite - loop). An extra check for rules containing '#' has also been added. - Since lex compiles regular expressions in verbose mode, '#' is interpreted - as a regex comment, it is critical to use '\#' instead. - -09/18/06: beazley - Added a @TOKEN decorator function to lex.py that can be used to - define token rules where the documentation string might be computed - in some way. - - digit = r'([0-9])' - nondigit = r'([_A-Za-z])' - identifier = r'(' + nondigit + r'(' + digit + r'|' + nondigit + r')*)' - - from ply.lex import TOKEN - - @TOKEN(identifier) - def t_ID(t): - # Do whatever - - The @TOKEN decorator merely sets the documentation string of the - associated token function as needed for lex to work. - - Note: An alternative solution is the following: - - def t_ID(t): - # Do whatever - - t_ID.__doc__ = identifier - - Note: Decorators require the use of Python 2.4 or later. If compatibility - with old versions is needed, use the latter solution. - - The need for this feature was suggested by Cem Karan. - -09/14/06: beazley - Support for single-character literal tokens has been added to yacc. - These literals must be enclosed in quotes. For example: - - def p_expr(p): - "expr : expr '+' expr" - ... - - def p_expr(p): - 'expr : expr "-" expr' - ... - - In addition to this, it is necessary to tell the lexer module about - literal characters. This is done by defining the variable 'literals' - as a list of characters. This should be defined in the module that - invokes the lex.lex() function. For example: - - literals = ['+','-','*','/','(',')','='] - - or simply - - literals = '+=*/()=' - - It is important to note that literals can only be a single character. - When the lexer fails to match a token using its normal regular expression - rules, it will check the current character against the literal list. - If found, it will be returned with a token type set to match the literal - character. Otherwise, an illegal character will be signalled. - - -09/14/06: beazley - Modified PLY to install itself as a proper Python package called 'ply'. - This will make it a little more friendly to other modules. This - changes the usage of PLY only slightly. Just do this to import the - modules - - import ply.lex as lex - import ply.yacc as yacc - - Alternatively, you can do this: - - from ply import * - - Which imports both the lex and yacc modules. - Change suggested by Lee June. - -09/13/06: beazley - Changed the handling of negative indices when used in production rules. - A negative production index now accesses already parsed symbols on the - parsing stack. For example, - - def p_foo(p): - "foo: A B C D" - print p[1] # Value of 'A' symbol - print p[2] # Value of 'B' symbol - print p[-1] # Value of whatever symbol appears before A - # on the parsing stack. - - p[0] = some_val # Sets the value of the 'foo' grammer symbol - - This behavior makes it easier to work with embedded actions within the - parsing rules. For example, in C-yacc, it is possible to write code like - this: - - bar: A { printf("seen an A = %d\n", $1); } B { do_stuff; } - - In this example, the printf() code executes immediately after A has been - parsed. Within the embedded action code, $1 refers to the A symbol on - the stack. - - To perform this equivalent action in PLY, you need to write a pair - of rules like this: - - def p_bar(p): - "bar : A seen_A B" - do_stuff - - def p_seen_A(p): - "seen_A :" - print "seen an A =", p[-1] - - The second rule "seen_A" is merely a empty production which should be - reduced as soon as A is parsed in the "bar" rule above. The use - of the negative index p[-1] is used to access whatever symbol appeared - before the seen_A symbol. - - This feature also makes it possible to support inherited attributes. - For example: - - def p_decl(p): - "decl : scope name" - - def p_scope(p): - """scope : GLOBAL - | LOCAL""" - p[0] = p[1] - - def p_name(p): - "name : ID" - if p[-1] == "GLOBAL": - # ... - else if p[-1] == "LOCAL": - #... - - In this case, the name rule is inheriting an attribute from the - scope declaration that precedes it. - - *** POTENTIAL INCOMPATIBILITY *** - If you are currently using negative indices within existing grammar rules, - your code will break. This should be extremely rare if non-existent in - most cases. The argument to various grammar rules is not usually not - processed in the same way as a list of items. - -Version 2.0 ------------------------------- -09/07/06: beazley - Major cleanup and refactoring of the LR table generation code. Both SLR - and LALR(1) table generation is now performed by the same code base with - only minor extensions for extra LALR(1) processing. - -09/07/06: beazley - Completely reimplemented the entire LALR(1) parsing engine to use the - DeRemer and Pennello algorithm for calculating lookahead sets. This - significantly improves the performance of generating LALR(1) tables - and has the added feature of actually working correctly! If you - experienced weird behavior with LALR(1) in prior releases, this should - hopefully resolve all of those problems. Many thanks to - Andrew Waters and Markus Schoepflin for submitting bug reports - and helping me test out the revised LALR(1) support. - -Version 1.8 ------------------------------- -08/02/06: beazley - Fixed a problem related to the handling of default actions in LALR(1) - parsing. If you experienced subtle and/or bizarre behavior when trying - to use the LALR(1) engine, this may correct those problems. Patch - contributed by Russ Cox. Note: This patch has been superceded by - revisions for LALR(1) parsing in Ply-2.0. - -08/02/06: beazley - Added support for slicing of productions in yacc. - Patch contributed by Patrick Mezard. - -Version 1.7 ------------------------------- -03/02/06: beazley - Fixed infinite recursion problem ReduceToTerminals() function that - would sometimes come up in LALR(1) table generation. Reported by - Markus Schoepflin. - -03/01/06: beazley - Added "reflags" argument to lex(). For example: - - lex.lex(reflags=re.UNICODE) - - This can be used to specify optional flags to the re.compile() function - used inside the lexer. This may be necessary for special situations such - as processing Unicode (e.g., if you want escapes like \w and \b to consult - the Unicode character property database). The need for this suggested by - Andreas Jung. - -03/01/06: beazley - Fixed a bug with an uninitialized variable on repeated instantiations of parser - objects when the write_tables=0 argument was used. Reported by Michael Brown. - -03/01/06: beazley - Modified lex.py to accept Unicode strings both as the regular expressions for - tokens and as input. Hopefully this is the only change needed for Unicode support. - Patch contributed by Johan Dahl. - -03/01/06: beazley - Modified the class-based interface to work with new-style or old-style classes. - Patch contributed by Michael Brown (although I tweaked it slightly so it would work - with older versions of Python). - -Version 1.6 ------------------------------- -05/27/05: beazley - Incorporated patch contributed by Christopher Stawarz to fix an extremely - devious bug in LALR(1) parser generation. This patch should fix problems - numerous people reported with LALR parsing. - -05/27/05: beazley - Fixed problem with lex.py copy constructor. Reported by Dave Aitel, Aaron Lav, - and Thad Austin. - -05/27/05: beazley - Added outputdir option to yacc() to control output directory. Contributed - by Christopher Stawarz. - -05/27/05: beazley - Added rununit.py test script to run tests using the Python unittest module. - Contributed by Miki Tebeka. - -Version 1.5 ------------------------------- -05/26/04: beazley - Major enhancement. LALR(1) parsing support is now working. - This feature was implemented by Elias Ioup (ezioup@alumni.uchicago.edu) - and optimized by David Beazley. To use LALR(1) parsing do - the following: - - yacc.yacc(method="LALR") - - Computing LALR(1) parsing tables takes about twice as long as - the default SLR method. However, LALR(1) allows you to handle - more complex grammars. For example, the ANSI C grammar - (in example/ansic) has 13 shift-reduce conflicts with SLR, but - only has 1 shift-reduce conflict with LALR(1). - -05/20/04: beazley - Added a __len__ method to parser production lists. Can - be used in parser rules like this: - - def p_somerule(p): - """a : B C D - | E F" - if (len(p) == 3): - # Must have been first rule - elif (len(p) == 2): - # Must be second rule - - Suggested by Joshua Gerth and others. - -Version 1.4 ------------------------------- -04/23/04: beazley - Incorporated a variety of patches contributed by Eric Raymond. - These include: - - 0. Cleans up some comments so they don't wrap on an 80-column display. - 1. Directs compiler errors to stderr where they belong. - 2. Implements and documents automatic line counting when \n is ignored. - 3. Changes the way progress messages are dumped when debugging is on. - The new format is both less verbose and conveys more information than - the old, including shift and reduce actions. - -04/23/04: beazley - Added a Python setup.py file to simply installation. Contributed - by Adam Kerrison. - -04/23/04: beazley - Added patches contributed by Adam Kerrison. - - - Some output is now only shown when debugging is enabled. This - means that PLY will be completely silent when not in debugging mode. - - - An optional parameter "write_tables" can be passed to yacc() to - control whether or not parsing tables are written. By default, - it is true, but it can be turned off if you don't want the yacc - table file. Note: disabling this will cause yacc() to regenerate - the parsing table each time. - -04/23/04: beazley - Added patches contributed by David McNab. This patch addes two - features: - - - The parser can be supplied as a class instead of a module. - For an example of this, see the example/classcalc directory. - - - Debugging output can be directed to a filename of the user's - choice. Use - - yacc(debugfile="somefile.out") - - -Version 1.3 ------------------------------- -12/10/02: jmdyck - Various minor adjustments to the code that Dave checked in today. - Updated test/yacc_{inf,unused}.exp to reflect today's changes. - -12/10/02: beazley - Incorporated a variety of minor bug fixes to empty production - handling and infinite recursion checking. Contributed by - Michael Dyck. - -12/10/02: beazley - Removed bogus recover() method call in yacc.restart() - -Version 1.2 ------------------------------- -11/27/02: beazley - Lexer and parser objects are now available as an attribute - of tokens and slices respectively. For example: - - def t_NUMBER(t): - r'\d+' - print t.lexer - - def p_expr_plus(t): - 'expr: expr PLUS expr' - print t.lexer - print t.parser - - This can be used for state management (if needed). - -10/31/02: beazley - Modified yacc.py to work with Python optimize mode. To make - this work, you need to use - - yacc.yacc(optimize=1) - - Furthermore, you need to first run Python in normal mode - to generate the necessary parsetab.py files. After that, - you can use python -O or python -OO. - - Note: optimized mode turns off a lot of error checking. - Only use when you are sure that your grammar is working. - Make sure parsetab.py is up to date! - -10/30/02: beazley - Added cloning of Lexer objects. For example: - - import copy - l = lex.lex() - lc = copy.copy(l) - - l.input("Some text") - lc.input("Some other text") - ... - - This might be useful if the same "lexer" is meant to - be used in different contexts---or if multiple lexers - are running concurrently. - -10/30/02: beazley - Fixed subtle bug with first set computation and empty productions. - Patch submitted by Michael Dyck. - -10/30/02: beazley - Fixed error messages to use "filename:line: message" instead - of "filename:line. message". This makes error reporting more - friendly to emacs. Patch submitted by François Pinard. - -10/30/02: beazley - Improvements to parser.out file. Terminals and nonterminals - are sorted instead of being printed in random order. - Patch submitted by François Pinard. - -10/30/02: beazley - Improvements to parser.out file output. Rules are now printed - in a way that's easier to understand. Contributed by Russ Cox. - -10/30/02: beazley - Added 'nonassoc' associativity support. This can be used - to disable the chaining of operators like a < b < c. - To use, simply specify 'nonassoc' in the precedence table - - precedence = ( - ('nonassoc', 'LESSTHAN', 'GREATERTHAN'), # Nonassociative operators - ('left', 'PLUS', 'MINUS'), - ('left', 'TIMES', 'DIVIDE'), - ('right', 'UMINUS'), # Unary minus operator - ) - - Patch contributed by Russ Cox. - -10/30/02: beazley - Modified the lexer to provide optional support for Python -O and -OO - modes. To make this work, Python *first* needs to be run in - unoptimized mode. This reads the lexing information and creates a - file "lextab.py". Then, run lex like this: - - # module foo.py - ... - ... - lex.lex(optimize=1) - - Once the lextab file has been created, subsequent calls to - lex.lex() will read data from the lextab file instead of using - introspection. In optimized mode (-O, -OO) everything should - work normally despite the loss of doc strings. - - To change the name of the file 'lextab.py' use the following: - - lex.lex(lextab="footab") - - (this creates a file footab.py) - - -Version 1.1 October 25, 2001 ------------------------------- - -10/25/01: beazley - Modified the table generator to produce much more compact data. - This should greatly reduce the size of the parsetab.py[c] file. - Caveat: the tables still need to be constructed so a little more - work is done in parsetab on import. - -10/25/01: beazley - There may be a possible bug in the cycle detector that reports errors - about infinite recursion. I'm having a little trouble tracking it - down, but if you get this problem, you can disable the cycle - detector as follows: - - yacc.yacc(check_recursion = 0) - -10/25/01: beazley - Fixed a bug in lex.py that sometimes caused illegal characters to be - reported incorrectly. Reported by Sverre Jørgensen. - -7/8/01 : beazley - Added a reference to the underlying lexer object when tokens are handled by - functions. The lexer is available as the 'lexer' attribute. This - was added to provide better lexing support for languages such as Fortran - where certain types of tokens can't be conveniently expressed as regular - expressions (and where the tokenizing function may want to perform a - little backtracking). Suggested by Pearu Peterson. - -6/20/01 : beazley - Modified yacc() function so that an optional starting symbol can be specified. - For example: - - yacc.yacc(start="statement") - - Normally yacc always treats the first production rule as the starting symbol. - However, if you are debugging your grammar it may be useful to specify - an alternative starting symbol. Idea suggested by Rich Salz. - -Version 1.0 June 18, 2001 --------------------------- -Initial public offering - diff --git a/chall/ply-2.2/COPYING b/chall/ply-2.2/COPYING deleted file mode 100644 index b1e3f5a..0000000 --- a/chall/ply-2.2/COPYING +++ /dev/null @@ -1,504 +0,0 @@ - GNU LESSER GENERAL PUBLIC LICENSE - Version 2.1, February 1999 - - Copyright (C) 1991, 1999 Free Software Foundation, Inc. - 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA - Everyone is permitted to copy and distribute verbatim copies - of this license document, but changing it is not allowed. - -[This is the first released version of the Lesser GPL.

You -can use it too, but we suggest you first think carefully about whether -this license or the ordinary General Public License is the better -strategy to use in any particular case, based on the explanations below. - - When we speak of free software, we are referring to freedom of use, -not price. Our General Public Licenses are designed to make sure that -you have the freedom to distribute copies of free software (and charge -for this service if you wish); that you receive source code or can get -it if you want it; that you can change the software and use pieces of -it in new free programs; and that you are informed that you can do -these things. - - To protect your rights, we need to make restrictions that forbid -distributors to deny you these rights or to ask you to surrender these -rights. These restrictions translate to certain responsibilities for -you if you distribute copies of the library or if you modify it. - - For example, if you distribute copies of the library, whether gratis -or for a fee, you must give the recipients all the rights that we gave -you. You must make sure that they, too, receive or can get the source -code. If you link other code with the library, you must provide -complete object files to the recipients, so that they can relink them -with the library after making changes to the library and recompiling -it. And you must show them these terms so they know their rights. - - We protect your rights with a two-step method: (1) we copyright the -library, and (2) we offer you this license, which gives you legal -permission to copy, distribute and/or modify the library. - - To protect each distributor, we want to make it very clear that -there is no warranty for the free library. Also, if the library is -modified by someone else and passed on, the recipients should know -that what they have is not the original version, so that the original -author's reputation will not be affected by problems that might be -introduced by others. - - Finally, software patents pose a constant threat to the existence of -any free program. We wish to make sure that a company cannot -effectively restrict the users of a free program by obtaining a -restrictive license from a patent holder. Therefore, we insist that -any patent license obtained for a version of the library must be -consistent with the full freedom of use specified in this license. - - Most GNU software, including some libraries, is covered by the -ordinary GNU General Public License. This license, the GNU Lesser -General Public License, applies to certain designated libraries, and -is quite different from the ordinary General Public License. We use -this license for certain libraries in order to permit linking those -libraries into non-free programs. - - When a program is linked with a library, whether statically or using -a shared library, the combination of the two is legally speaking a -combined work, a derivative of the original library. The ordinary -General Public License therefore permits such linking only if the -entire combination fits its criteria of freedom. The Lesser General -Public License permits more lax criteria for linking other code with -the library. - - We call this license the "Lesser" General Public License because it -does Less to protect the user's freedom than the ordinary General -Public License. It also provides other free software developers Less -of an advantage over competing non-free programs. These disadvantages -are the reason we use the ordinary General Public License for many -libraries. However, the Lesser license provides advantages in certain -special circumstances. - - For example, on rare occasions, there may be a special need to -encourage the widest possible use of a certain library, so that it becomes -a de-facto standard. To achieve this, non-free programs must be -allowed to use the library. A more frequent case is that a free -library does the same job as widely used non-free libraries. In this -case, there is little to gain by limiting the free library to free -software only, so we use the Lesser General Public License. - - In other cases, permission to use a particular library in non-free -programs enables a greater number of people to use a large body of -free software. For example, permission to use the GNU C Library in -non-free programs enables many more people to use the whole GNU -operating system, as well as its variant, the GNU/Linux operating -system. - - Although the Lesser General Public License is Less protective of the -users' freedom, it does ensure that the user of a program that is -linked with the Library has the freedom and the wherewithal to run -that program using a modified version of the Library. - - The precise terms and conditions for copying, distribution and -modification follow. Pay close attention to the difference between a -"work based on the library" and a "work that uses the library".

This License Agreement applies to any software library or other -program which contains a notice placed by the copyright holder or -other authorized party saying it may be distributed under the terms of -this Lesser General Public License (also called "this License"). -Each licensee is addressed as "you". - - A "library" means a collection of software functions and/or data -prepared so as to be conveniently linked with application programs -(which use some of those functions and data) to form executables. - - The "Library", below, refers to any such software library or work -which has been distributed under these terms. A "work based on the -Library" means either the Library or any derivative work under -copyright law: that is to say, a work containing the Library or a -portion of it, either verbatim or with modifications and/or translated -straightforwardly into another language. (Hereinafter, translation is -included without limitation in the term "modification".) - - "Source code" for a work means the preferred form of the work for -making modifications to it. For a library, complete source code means -all the source code for all modules it contains, plus any associated -interface definition files, plus the scripts used to control compilation -and installation of the library. - - Activities other than copying, distribution and modification are not -covered by this License; they are outside its scope. The act of -running a program using the Library is not restricted, and output from -such a program is covered only if its contents constitute a work based -on the Library (independent of the use of the Library in a tool for -writing it). Whether that is true depends on what the Library does -and what the program that uses the Library does. - - 1. You may copy and distribute verbatim copies of the Library's -complete source code as you receive it, in any medium, provided that -you conspicuously and appropriately publish on each copy an -appropriate copyright notice and disclaimer of warranty; keep intact -all the notices that refer to this License and to the absence of any -warranty; and distribute a copy of this License along with the -Library. - - You may charge a fee for the physical act of transferring a copy, -and you may at your option offer warranty protection in exchange for a -fee. - - 2. You may modify your copy or copies of the Library or any portion -of it, thus forming a work based on the Library, and copy and -distribute such modifications or work under the terms of Section 1 -above, provided that you also meet all of these conditions: - - a) The modified work must itself be a software library. - - b) You must cause the files modified to carry prominent notices - stating that you changed the files and the date of any change. - - c) You must cause the whole of the work to be licensed at no - charge to all third parties under the terms of this License. - - d) If a facility in the modified Library refers to a function or a - table of data to be supplied by an application program that uses - the facility, other than as an argument passed when the facility - is invoked, then you must make a good faith effort to ensure that, - in the event an application does not supply such function or - table, the facility still operates, and performs whatever part of - its purpose remains meaningful. - - (For example, a function in a library to compute square roots has - a purpose that is entirely well-defined independent of the - application. Therefore, Subsection 2d requires that any - application-supplied function or table used by this function must - be optional: if the application does not supply it, the square - root function must still compute square roots.) - -These requirements apply to the modified work as a whole. If -identifiable sections of that work are not derived from the Library, -and can be reasonably considered independent and separate works in -themselves, then this License, and its terms, do not apply to those -sections when you distribute them as separate works. But when you -distribute the same sections as part of a whole which is a work based -on the Library, the distribution of the whole must be on the terms of -this License, whose permissions for other licensees extend to the -entire whole, and thus to each and every part regardless of who wrote -it. - -Thus, it is not the intent of this section to claim rights or contest -your rights to work written entirely by you; rather, the intent is to -exercise the right to control the distribution of derivative or -collective works based on the Library. - -In addition, mere aggregation of another work not based on the Library -with the Library (or with a work based on the Library) on a volume of -a storage or distribution medium does not bring the other work under -the scope of this License. - - 3. You may opt to apply the terms of the ordinary GNU General Public -License instead of this License to a given copy of the Library. To do -this, you must alter all the notices that refer to this License, so -that they refer to the ordinary GNU General Public License, version 2, -instead of to this License. (If a newer version than version 2 of the -ordinary GNU General Public License has appeared, then you can specify -that version instead if you wish.) Do not make any other change in -these notices. - - Once this change is made in a given copy, it is irreversible for -that copy, so the ordinary GNU General Public License applies to all -subsequent copies and derivative works made from that copy. - - This option is useful when you wish to copy part of the code of -the Library into a program that is not a library. - - 4. You may copy and distribute the Library (or a portion or -derivative of it, under Section 2) in object code or executable form -under the terms of Sections 1 and 2 above provided that you accompany -it with the complete corresponding machine-readable source code, which -must be distributed under the terms of Sections 1 and 2 above on a -medium customarily used for software interchange. - - If distribution of object code is made by offering access to copy -from a designated place, then offering equivalent access to copy the -source code from the same place satisfies the requirement to -distribute the source code, even though third parties are not -compelled to copy the source along with the object code. - - 5. A program that contains no derivative of any portion of the -Library, but is designed to work with the Library by being compiled or -linked with it, is called a "work that uses the Library". Such a -work, in isolation, is not a derivative work of the Library, and -therefore falls outside the scope of this License. - - However, linking a "work that uses the Library" with the Library -creates an executable that is a derivative of the Library (because it -contains portions of the Library), rather than a "work that uses the -library". The executable is therefore covered by this License. -Section 6 states terms for distribution of such executables. - - When a "work that uses the Library" uses material from a header file -that is part of the Library, the object code for the work may be a -derivative work of the Library even though the source code is not. -Whether this is true is especially significant if the work can be -linked without the Library, or if the work is itself a library. The -threshold for this to be true is not precisely defined by law. - - If such an object file uses only numerical parameters, data -structure layouts and accessors, and small macros and small inline -functions (ten lines or less in length), then the use of the object -file is unrestricted, regardless of whether it is legally a derivative -work. (Executables containing this object code plus portions of the -Library will still fall under Section 6.) - - Otherwise, if the work is a derivative of the Library, you may -distribute the object code for the work under the terms of Section 6. -Any executables containing that work also fall under Section 6, -whether or not they are linked directly with the Library itself. - - 6. As an exception to the Sections above, you may also combine or -link a "work that uses the Library" with the Library to produce a -work containing portions of the Library, and distribute that work -under terms of your choice, provided that the terms permit -modification of the work for the customer's own use and reverse -engineering for debugging such modifications. - - You must give prominent notice with each copy of the work that the -Library is used in it and that the Library and its use are covered by -this License. You must supply a copy of this License. If the work -during execution displays copyright notices, you must include the -copyright notice for the Library among them, as well as a reference -directing the user to the copy of this License. Also, you must do one -of these things: - - a) Accompany the work with the complete corresponding - machine-readable source code for the Library including whatever - changes were used in the work (which must be distributed under - Sections 1 and 2 above); and, if the work is an executable linked - with the Library, with the complete machine-readable "work that - uses the Library", as object code and/or source code, so that the - user can modify the Library and then relink to produce a modified - executable containing the modified Library. (It is understood - that the user who changes the contents of definitions files in the - Library will not necessarily be able to recompile the application - to use the modified definitions.) - - b) Use a suitable shared library mechanism for linking with the - Library. A suitable mechanism is one that (1) uses at run time a - copy of the library already present on the user's computer system, - rather than copying library functions into the executable, and (2) - will operate properly with a modified version of the library, if - the user installs one, as long as the modified version is - interface-compatible with the version that the work was made with. - - c) Accompany the work with a written offer, valid for at - least three years, to give the same user the materials - specified in Subsection 6a, above, for a charge no more - than the cost of performing this distribution. - - d) If distribution of the work is made by offering access to copy - from a designated place, offer equivalent access to copy the above - specified materials from the same place. - - e) Verify that the user has already received a copy of these - materials or that you have already sent this user a copy. - - For an executable, the required form of the "work that uses the -Library" must include any data and utility programs needed for -reproducing the executable from it. However, as a special exception, -the materials to be distributed need not include anything that is -normally distributed (in either source or binary form) with the major -components (compiler, kernel, and so on) of the operating system on -which the executable runs, unless that component itself accompanies -the executable. - - It may happen that this requirement contradicts the license -restrictions of other proprietary libraries that do not normally -accompany the operating system. Such a contradiction means you cannot -use both them and the Library together in an executable that you -distribute. - - 7. You may place library facilities that are a work based on the -Library side-by-side in a single library together with other library -facilities not covered by this License, and distribute such a combined -library, provided that the separate distribution of the work based on -the Library and of the other library facilities is otherwise -permitted, and provided that you do these two things: - - a) Accompany the combined library with a copy of the same work - based on the Library, uncombined with any other library - facilities. This must be distributed under the terms of the - Sections above. - - b) Give prominent notice with the combined library of the fact - that part of it is a work based on the Library, and explaining - where to find the accompanying uncombined form of the same work. - - 8. You may not copy, modify, sublicense, link with, or distribute -the Library except as expressly provided under this License. Any -attempt otherwise to copy, modify, sublicense, link with, or -distribute the Library is void, and will automatically terminate your -rights under this License. However, parties who have received copies, -or rights, from you under this License will not have their licenses -terminated so long as such parties remain in full compliance. - - 9. You are not required to accept this License, since you have not -signed it. However, nothing else grants you permission to modify or -distribute the Library or its derivative works. These actions are -prohibited by law if you do not accept this License. Therefore, by -modifying or distributing the Library (or any work based on the -Library), you indicate your acceptance of this License to do so, and -all its terms and conditions for copying, distributing or modifying -the Library or works based on it. - - 10. Each time you redistribute the Library (or any work based on the -Library), the recipient automatically receives a license from the -original licensor to copy, distribute, link with or modify the Library -subject to these terms and conditions. You may not impose any further -restrictions on the recipients' exercise of the rights granted herein. -You are not responsible for enforcing compliance by third parties with -this License. - - 11. If, as a consequence of a court judgment or allegation of patent -infringement or for any other reason (not limited to patent issues), -conditions are imposed on you (whether by court order, agreement or -otherwise) that contradict the conditions of this License, they do not -excuse you from the conditions of this License. If you cannot -distribute so as to satisfy simultaneously your obligations under this -License and any other pertinent obligations, then as a consequence you -may not distribute the Library at all. For example, if a patent -license would not permit royalty-free redistribution of the Library by -all those who receive copies directly or indirectly through you, then -the only way you could satisfy both it and this License would be to -refrain entirely from distribution of the Library. - -If any portion of this section is held invalid or unenforceable under any -particular circumstance, the balance of the section is intended to apply, -and the section as a whole is intended to apply in other circumstances. - -It is not the purpose of this section to induce you to infringe any -patents or other property right claims or to contest validity of any -such claims; this section has the sole purpose of protecting the -integrity of the free software distribution system which is -implemented by public license practices. Many people have made -generous contributions to the wide range of software distributed -through that system in reliance on consistent application of that -system; it is up to the author/donor to decide if he or she is willing -to distribute software through any other system and a licensee cannot -impose that choice. - -This section is intended to make thoroughly clear what is believed to -be a consequence of the rest of this License. - - 12. If the distribution and/or use of the Library is restricted in -certain countries either by patents or by copyrighted interfaces, the -original copyright holder who places the Library under this License may add -an explicit geographical distribution limitation excluding those countries, -so that distribution is permitted only in or among countries not thus -excluded. In such case, this License incorporates the limitation as if -written in the body of this License. - - 13. The Free Software Foundation may publish revised and/or new -versions of the Lesser General Public License from time to time. -Such new versions will be similar in spirit to the present version, -but may differ in detail to address new problems or concerns. - -Each version is given a distinguishing version number. If the Library -specifies a version number of this License which applies to it and -"any later version", you have the option of following the terms and -conditions either of that version or of any later version published by -the Free Software Foundation. If the Library does not specify a -license version number, you may choose any version ever published by -the Free Software Foundation. - - 14. If you wish to incorporate parts of the Library into other free -programs whose distribution conditions are incompatible with these, -write to the author to ask for permission. For software which is -copyrighted by the Free Software Foundation, write to the Free -Software Foundation; we sometimes make exceptions for this. Our -decision will be guided by the two goals of preserving the free status -of all derivatives of our free software and of promoting the sharing -and reuse of software generally. - - NO WARRANTY - - 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO -WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. -EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR -OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY -KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE -IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR -PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE -LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME -THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. - - 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN -WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY -AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU -FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR -CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE -LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING -RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A -FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF -SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH -DAMAGES. - - END OF TERMS AND CONDITIONS - - How to Apply These Terms to Your New Libraries - - If you develop a new library, and you want it to be of the greatest -possible use to the public, we recommend making it free software that -everyone can redistribute and change.

Although several other parsing tools are available for -Python, there are several reasons why you might want to consider PLY: - - - The tools are very closely modeled after traditional lex/yacc. - If you know how to use these tools in C, you will find PLY - to be similar. - - - PLY provides *very* extensive error reporting and diagnostic - information to assist in parser construction. The original - implementation was developed for instructional purposes. As - a result, the system tries to identify the most common types - of errors made by novice users. - - - PLY provides full support for empty productions, error recovery, - precedence specifiers, and moderately ambiguous grammars. - - - Parsing is based on LR-parsing which is fast, memory efficient, - better suited to large grammars, and which has a number of nice - properties when dealing with syntax errors and other parsing problems. - Currently, PLY builds its parsing tables using the SLR algorithm which - is slightly weaker than LALR(1) used in traditional yacc. - - - PLY uses Python introspection features to build lexers and parsers. - This greatly simplifies the task of parser construction since it reduces - the number of files and eliminates the need to run a separate lex/yacc - tool before running your program. - - - PLY can be used to build parsers for "real" programming languages. - Although it is not ultra-fast due to its Python implementation, - PLY can be used to parse grammars consisting of several hundred - rules (as might be found for a language like C). The lexer and LR - parser are also reasonably efficient when parsing typically - sized programs. - -The original version of PLY was developed for an Introduction to -Compilers course where students used it to build a compiler for a -simple Pascal-like language. Their compiler had to include lexical -analysis, parsing, type checking, type inference, and generation of -assembly code for the SPARC processor. Because of this, the current -implementation has been extensively tested and debugged. In addition, -most of the API and error checking steps have been adapted to address -common usability problems. - -How to Use -========== - -PLY consists of two files : lex.py and yacc.py. These are contained -within the 'ply' directory which may also be used as a Python package. -To use PLY, simply copy the 'ply' directory to your project and import -lex and yacc from the associated 'ply' package. For example: - - import ply.lex as lex - import ply.yacc as yacc - -Alternatively, you can copy just the files lex.py and yacc.py -individually and use them as modules. For example: - - import lex - import yacc - -The file setup.py can be used to install ply using distutils. - -The file doc/ply.html contains complete documentation on how to use -the system. - -The example directory contains several different examples including a -PLY specification for ANSI C as given in K&R 2nd Ed. - -A simple example is found at the end of this document - -Requirements -============ -PLY requires the use of Python 2.0 or greater. It should work on -just about any platform. PLY has been tested with both CPython and -Jython. However, it does not work with IronPython. - -Resources -========= -More information about PLY can be obtained on the PLY webpage at: - - http://www.dabeaz.com/ply - -For a detailed overview of parsing theory, consult the excellent -book "Compilers : Principles, Techniques, and Tools" by Aho, Sethi, and -Ullman. The topics found in "Lex & Yacc" by Levine, Mason, and Brown -may also be useful. - -A Google group for PLY can be found at - - http://groups.google.com/group/ply-hack - -Acknowledgments -=============== -A special thanks is in order for all of the students in CS326 who -suffered through about 25 different versions of these tools :-). - -The CHANGES file acknowledges those who have contributed patches. - -Elias Ioup did the first implementation of LALR(1) parsing in PLY-1.x. -Andrew Waters and Markus Schoepflin were instrumental in reporting bugs -and testing a revised LALR(1) implementation for PLY-2.0. - -Special Note for PLY-2.x -======================== -PLY-2.0 is the first in a series of PLY releases that will be adding a -variety of significant new features. The first release in this series -(Ply-2.0) should be 100% compatible with all previous Ply-1.x releases -except for the fact that Ply-2.0 features a correct implementation of -LALR(1) table generation. - -If you have suggestions for improving PLY in future 2.x releases, please -contact me. - Dave - -Example -======= - -Here is a simple example showing a PLY implementation of a calculator -with variables. - -# ----------------------------------------------------------------------------- -# calc.py -# -# A simple calculator with variables. -# ----------------------------------------------------------------------------- - -tokens = ( - 'NAME','NUMBER', - 'PLUS','MINUS','TIMES','DIVIDE','EQUALS', - 'LPAREN','RPAREN', - ) - -# Tokens - -t_PLUS = r'\+' -t_MINUS = r'-' -t_TIMES = r'\*' -t_DIVIDE = r'/' -t_EQUALS = r'=' -t_LPAREN = r'\(' -t_RPAREN = r'\)' -t_NAME = r'[a-zA-Z_][a-zA-Z0-9_]*' - -def t_NUMBER(t): - r'\d+' - try: - t.value = int(t.value) - except ValueError: - print "Integer value too large", t.value - t.value = 0 - return t - -# Ignored characters -t_ignore = " \t" - -def t_newline(t): - r'\n+' - t.lexer.lineno += t.value.count("\n") - -def t_error(t): - print "Illegal character '%s'" % t.value[0] - t.lexer.skip(1) - -# Build the lexer -import ply.lex as lex -lex.lex() - -# Precedence rules for the arithmetic operators -precedence = ( - ('left','PLUS','MINUS'), - ('left','TIMES','DIVIDE'), - ('right','UMINUS'), - ) - -# dictionary of names (for storing variables) -names = { } - -def p_statement_assign(p): - 'statement : NAME EQUALS expression' - names[p[1]] = p[3] - -def p_statement_expr(p): - 'statement : expression' - print p[1] - -def p_expression_binop(p): - '''expression : expression PLUS expression - | expression MINUS expression - | expression TIMES expression - | expression DIVIDE expression''' - if p[2] == '+' : p[0] = p[1] + p[3] - elif p[2] == '-': p[0] = p[1] - p[3] - elif p[2] == '*': p[0] = p[1] * p[3] - elif p[2] == '/': p[0] = p[1] / p[3] - -def p_expression_uminus(p): - 'expression : MINUS expression %prec UMINUS' - p[0] = -p[2] - -def p_expression_group(p): - 'expression : LPAREN expression RPAREN' - p[0] = p[2] - -def p_expression_number(p): - 'expression : NUMBER' - p[0] = p[1] - -def p_expression_name(p): - 'expression : NAME' - try: - p[0] = names[p[1]] - except LookupError: - print "Undefined name '%s'" % p[1] - p[0] = 0 - -def p_error(p): - print "Syntax error at '%s'" % p.value - -import ply.yacc as yacc -yacc.yacc() - -while 1: - try: - s = raw_input('calc > ') - except EOFError: - break - yacc.parse(s) - - -Bug Reports and Patches -======================= -Because of the extremely specialized and advanced nature of PLY, I -rarely spend much time working on it unless I receive very specific -bug-reports and/or patches to fix problems.

The grammer is specified by supplying the BNF inside -# Python documentation strings. The inspiration for this technique was borrowed -# from John Aycock's Spark parsing system. PLY might be viewed as cross between -# Spark and the GNU bison utility. -# -# The current implementation is only somewhat object-oriented. The -# LR parser itself is defined in terms of an object (which allows multiple -# parsers to co-exist). However, most of the variables used during table -# construction are defined in terms of global variables. Users shouldn't -# notice unless they are trying to define multiple parsers at the same -# time using threads (in which case they should have their head examined). -# -# This implementation supports both SLR and LALR(1) parsing. LALR(1) -# support was originally implemented by Elias Ioup (ezioup@alumni.uchicago.edu), -# using the algorithm found in Aho, Sethi, and Ullman "Compilers: Principles, -# Techniques, and Tools" (The Dragon Book). LALR(1) has since been replaced -# by the more efficient DeRemer and Pennello algorithm. -# -# :::::::: WARNING ::::::: -# -# Construction of LR parsing tables is fairly complicated and expensive. -# To make this module run fast, a *LOT* of work has been put into -# optimization---often at the expensive of readability and what might -# consider to be good Python "coding style."

Introduction</H2> - - -PLY is a pure-Python implementation of the popular compiler -construction tools lex and yacc. The main goal of PLY is to stay -fairly faithful to the way in which traditional lex/yacc tools work. -This includes supporting LALR(1) parsing as well as providing -extensive input validation, error reporting, and diagnostics. Thus, -if you've used yacc in another programming language, it should be -relatively straightforward to use PLY. - -<p> -Early versions of PLY were developed to support an Introduction to -Compilers Course I taught in 2001 at the University of Chicago. In this course, -students built a fully functional compiler for a simple Pascal-like -language. Their compiler, implemented entirely in Python, had to -include lexical analysis, parsing, type checking, type inference, -nested scoping, and code generation for the SPARC processor. -Approximately 30 different compiler implementations were completed in -this course. Most of PLY's interface and operation has been influenced by common -usability problems encountered by students. - -<p> -Since PLY was primarily developed as an instructional tool, you will -find it to be fairly picky about token and grammar rule -specification. In part, this -added formality is meant to catch common programming mistakes made by -novice users. However, advanced users will also find such features to -be useful when building complicated grammars for real programming -languages. It should also be noted that PLY does not provide much in -the way of bells and whistles (e.g., automatic construction of -abstract syntax trees, tree traversal, etc.). Nor would I consider it -to be a parsing framework. Instead, you will find a bare-bones, yet -fully capable lex/yacc implementation written entirely in Python. - -<p> -The rest of this document assumes that you are somewhat familar with -parsing theory, syntax directed translation, and the use of compiler -construction tools such as lex and yacc in other programming -languages. If you are unfamilar with these topics, you will probably -want to consult an introductory text such as "Compilers: Principles, -Techniques, and Tools", by Aho, Sethi, and Ullman. O'Reilly's "Lex -and Yacc" by John Levine may also be handy. In fact, the O'Reilly book can be -used as a reference for PLY as the concepts are virtually identical. - -<H2><a name="ply_nn2"></a>2. PLY Overview</H2> - - -PLY consists of two separate modules; <tt>lex.py</tt> and -<tt>yacc.py</tt>, both of which are found in a Python package -called <tt>ply</tt>. The <tt>lex.py</tt> module is used to break input text into a -collection of tokens specified by a collection of regular expression -rules. <tt>yacc.py</tt> is used to recognize language syntax that has -been specified in the form of a context free grammar. <tt>yacc.py</tt> uses LR parsing and generates its parsing tables -using either the LALR(1) (the default) or SLR table generation algorithms. - -<p> -The two tools are meant to work together. Specifically, -<tt>lex.py</tt> provides an external interface in the form of a -<tt>token()</tt> function that returns the next valid token on the -input stream. <tt>yacc.py</tt> calls this repeatedly to retrieve -tokens and invoke grammar rules. The output of <tt>yacc.py</tt> is -often an Abstract Syntax Tree (AST). However, this is entirely up to -the user. If desired, <tt>yacc.py</tt> can also be used to implement -simple one-pass compilers. - -<p> -Like its Unix counterpart, <tt>yacc.py</tt> provides most of the -features you expect including extensive error checking, grammar -validation, support for empty productions, error tokens, and ambiguity -resolution via precedence rules. In fact, everything that is possible in traditional yacc -should be supported in PLY. - -<p> -The primary difference between -<tt>yacc.py</tt> and Unix <tt>yacc</tt> is that <tt>yacc.py</tt> -doesn't involve a separate code-generation process. -Instead, PLY relies on reflection (introspection) -to build its lexers and parsers. Unlike traditional lex/yacc which -require a special input file that is converted into a separate source -file, the specifications given to PLY <em>are</em> valid Python -programs. This means that there are no extra source files nor is -there a special compiler construction step (e.g., running yacc to -generate Python code for the compiler). Since the generation of the -parsing tables is relatively expensive, PLY caches the results and -saves them to a file. If no changes are detected in the input source, -the tables are read from the cache. Otherwise, they are regenerated. - -<H2><a name="ply_nn3"></a>3. Lex</H2> - - -<tt>lex.py</tt> is used to tokenize an input string. For example, suppose -you're writing a programming language and a user supplied the following input string: - -<blockquote> -<pre> -x = 3 + 42 * (s - t) -</pre> -</blockquote> - -A tokenizer splits the string into individual tokens - -<blockquote> -<pre> -'x','=', '3', '+', '42', '*', '(', 's', '-', 't', ')' -</pre> -</blockquote> - -Tokens are usually given names to indicate what they are. For example: - -<blockquote> -<pre> -'ID','EQUALS','NUMBER','PLUS','NUMBER','TIMES', -'LPAREN','ID','MINUS','ID','RPAREN' -</pre> -</blockquote> - -More specifically, the input is broken into pairs of token types and values. For example: - -<blockquote> -<pre> -('ID','x'), ('EQUALS','='), ('NUMBER','3'), -('PLUS','+'), ('NUMBER','42), ('TIMES','*'), -('LPAREN','('), ('ID','s'), ('MINUS','-'), -('ID','t'), ('RPAREN',')' -</pre> -</blockquote> - -The identification of tokens is typically done by writing a series of regular expression -rules. The next section shows how this is done using <tt>lex.py</tt>. - -<H3><a name="ply_nn4"></a>3.1 Lex Example</H3> - - -The following example shows how <tt>lex.py</tt> is used to write a simple tokenizer. - -<blockquote> -<pre> -# ------------------------------------------------------------ -# calclex.py -# -# tokenizer for a simple expression evaluator for -# numbers and +,-,*,/ -# ------------------------------------------------------------ -import ply.lex as lex - -# List of token names. This is always required -tokens = ( - 'NUMBER', - 'PLUS', - 'MINUS', - 'TIMES', - 'DIVIDE', - 'LPAREN', - 'RPAREN', -) - -# Regular expression rules for simple tokens -t_PLUS = r'\+' -t_MINUS = r'-' -t_TIMES = r'\*' -t_DIVIDE = r'/' -t_LPAREN = r'\(' -t_RPAREN = r'\)' - -# A regular expression rule with some action code -def t_NUMBER(t): - r'\d+' - try: - t.value = int(t.value) - except ValueError: - print "Line %d: Number %s is too large!" % (t.lineno,t.value) - t.value = 0 - return t - -# Define a rule so we can track line numbers -def t_newline(t): - r'\n+' - t.lexer.lineno += len(t.value) - -# A string containing ignored characters (spaces and tabs) -t_ignore = ' \t' - -# Error handling rule -def t_error(t): - print "Illegal character '%s'" % t.value[0] - t.lexer.skip(1) - -# Build the lexer -lex.lex() - -</pre> -</blockquote> -To use the lexer, you first need to feed it some input text using its <tt>input()</tt> method. After that, repeated calls to <tt>token()</tt> produce tokens. The following code shows how this works: - -<blockquote> -<pre> - -# Test it out -data = ''' -3 + 4 * 10 - + -20 *2 -''' - -# Give the lexer some input -lex.input(data) - -# Tokenize -while 1: - tok = lex.token() - if not tok: break # No more input - print tok -</pre> -</blockquote> - -When executed, the example will produce the following output: - -<blockquote> -<pre> -$ python example.py -LexToken(NUMBER,3,2,1) -LexToken(PLUS,'+',2,3) -LexToken(NUMBER,4,2,5) -LexToken(TIMES,'*',2,7) -LexToken(NUMBER,10,2,10) -LexToken(PLUS,'+',3,14) -LexToken(MINUS,'-',3,16) -LexToken(NUMBER,20,3,18) -LexToken(TIMES,'*',3,20) -LexToken(NUMBER,2,3,21) -</pre> -</blockquote> - -The tokens returned by <tt>lex.token()</tt> are instances -of <tt>LexToken</tt>. This object has -attributes <tt>tok.type</tt>, <tt>tok.value</tt>, -<tt>tok.lineno</tt>, and <tt>tok.lexpos</tt>. The following code shows an example of -accessing these attributes: - -<blockquote> -<pre> -# Tokenize -while 1: - tok = lex.token() - if not tok: break # No more input - print tok.type, tok.value, tok.line, tok.lexpos -</pre> -</blockquote> - -The <tt>tok.type</tt> and <tt>tok.value</tt> attributes contain the -type and value of the token itself. -<tt>tok.line</tt> and <tt>tok.lexpos</tt> contain information about -the location of the token. <tt>tok.lexpos</tt> is the index of the -token relative to the start of the input text. - -<H3><a name="ply_nn5"></a>3.2 The tokens list</H3> - - -All lexers must provide a list <tt>tokens</tt> that defines all of the possible token -names that can be produced by the lexer. This list is always required -and is used to perform a variety of validation checks. The tokens list is also used by the -<tt>yacc.py</tt> module to identify terminals. - -<p> -In the example, the following code specified the token names: - -<blockquote> -<pre> -tokens = ( - 'NUMBER', - 'PLUS', - 'MINUS', - 'TIMES', - 'DIVIDE', - 'LPAREN', - 'RPAREN', -) -</pre> -</blockquote> - -<H3><a name="ply_nn6"></a>3.3 Specification of tokens</H3> - - -Each token is specified by writing a regular expression rule. Each of these rules are -are defined by making declarations with a special prefix <tt>t_</tt> to indicate that it -defines a token. For simple tokens, the regular expression can -be specified as strings such as this (note: Python raw strings are used since they are the -most convenient way to write regular expression strings): - -<blockquote> -<pre> -t_PLUS = r'\+' -</pre> -</blockquote> - -In this case, the name following the <tt>t_</tt> must exactly match one of the -names supplied in <tt>tokens</tt>. If some kind of action needs to be performed, -a token rule can be specified as a function. For example, this rule matches numbers and -converts the string into a Python integer. - -<blockquote> -<pre> -def t_NUMBER(t): - r'\d+' - try: - t.value = int(t.value) - except ValueError: - print "Number %s is too large!" % t.value - t.value = 0 - return t -</pre> -</blockquote> - -When a function is used, the regular expression rule is specified in the function documentation string. -The function always takes a single argument which is an instance of -<tt>LexToken</tt>. This object has attributes of <tt>t.type</tt> which is the token type (as a string), -<tt>t.value</tt> which is the lexeme (the actual text matched), <tt>t.lineno</tt> which is the current line number, and <tt>t.lexpos</tt> which -is the position of the token relative to the beginning of the input text. -By default, <tt>t.type</tt> is set to the name following the <tt>t_</tt> prefix. The action -function can modify the contents of the <tt>LexToken</tt> object as appropriate. However, -when it is done, the resulting token should be returned. If no value is returned by the action -function, the token is simply discarded and the next token read. - -<p> -Internally, <tt>lex.py</tt> uses the <tt>re</tt> module to do its patten matching. When building the master regular expression, -rules are added in the following order: -<p> -<ol> -<li>All tokens defined by functions are added in the same order as they appear in the lexer file. -<li>Tokens defined by strings are added next by sorting them in order of decreasing regular expression length (longer expressions -are added first). -</ol> -<p> -Without this ordering, it can be difficult to correctly match certain types of tokens. For example, if you -wanted to have separate tokens for "=" and "==", you need to make sure that "==" is checked first. By sorting regular -expressions in order of decreasing length, this problem is solved for rules defined as strings. For functions, -the order can be explicitly controlled since rules appearing first are checked first. - -<p> -To handle reserved words, it is usually easier to just match an identifier and do a special name lookup in a function -like this: - -<blockquote> -<pre> -reserved = { - 'if' : 'IF', - 'then' : 'THEN', - 'else' : 'ELSE', - 'while' : 'WHILE', - ... -} - -def t_ID(t): - r'[a-zA-Z_][a-zA-Z_0-9]*' - t.type = reserved.get(t.value,'ID') # Check for reserved words - return t -</pre> -</blockquote> - -This approach greatly reduces the number of regular expression rules and is likely to make things a little faster. - -<p> -<b>Note:</b> You should avoid writing individual rules for reserved words. For example, if you write rules like this, - -<blockquote> -<pre> -t_FOR = r'for' -t_PRINT = r'print' -</pre> -</blockquote> - -those rules will be triggered for identifiers that include those words as a prefix such as "forget" or "printed". This is probably not -what you want. - -<H3><a name="ply_nn7"></a>3.4 Token values</H3> - - -When tokens are returned by lex, they have a value that is stored in the <tt>value</tt> attribute. Normally, the value is the text -that was matched. However, the value can be assigned to any Python object. For instance, when lexing identifiers, you may -want to return both the identifier name and information from some sort of symbol table. To do this, you might write a rule like this: - -<blockquote> -<pre> -def t_ID(t): - ... - # Look up symbol table information and return a tuple - t.value = (t.value, symbol_lookup(t.value)) - ... - return t -</pre> -</blockquote> - -It is important to note that storing data in other attribute names is <em>not</em> recommended. The <tt>yacc.py</tt> module only exposes the -contents of the <tt>value</tt> attribute. Thus, accessing other attributes may be unnecessarily awkward. - -<H3><a name="ply_nn8"></a>3.5 Discarded tokens</H3> - - -To discard a token, such as a comment, simply define a token rule that returns no value. For example: - -<blockquote> -<pre> -def t_COMMENT(t): - r'\#.*' - pass - # No return value. Token discarded -</pre> -</blockquote> - -Alternatively, you can include the prefix "ignore_" in the token declaration to force a token to be ignored. For example: - -<blockquote> -<pre> -t_ignore_COMMENT = r'\#.*' -</pre> -</blockquote> - -Be advised that if you are ignoring many different kinds of text, you may still want to use functions since these provide more precise -control over the order in which regular expressions are matched (i.e., functions are matched in order of specification whereas strings are -sorted by regular expression length). - -<H3><a name="ply_nn9"></a>3.6 Line numbers and positional information</H3> - - -<p>By default, <tt>lex.py</tt> knows nothing about line numbers. This is because <tt>lex.py</tt> doesn't know anything -about what constitutes a "line" of input (e.g., the newline character or even if the input is textual data). -To update this information, you need to write a special rule. In the example, the <tt>t_newline()</tt> rule shows how to do this. - -<blockquote> -<pre> -# Define a rule so we can track line numbers -def t_newline(t): - r'\n+' - t.lexer.lineno += len(t.value) -</pre> -</blockquote> -Within the rule, the <tt>lineno</tt> attribute of the underlying lexer <tt>t.lexer</tt> is updated. -After the line number is updated, the token is simply discarded since nothing is returned. - -<p> -<tt>lex.py</tt> does not perform and kind of automatic column tracking. However, it does record positional -information related to each token in the <tt>lexpos</tt> attribute. Using this, it is usually possible to compute -column information as a separate step. For instance, just count backwards until you reach a newline. - -<blockquote> -<pre> -# Compute column. -# input is the input text string -# token is a token instance -def find_column(input,token): - i = token.lexpos - while i > 0: - if input[i] == '\n': break - i -= 1 - column = (token.lexpos - i)+1 - return column -</pre> -</blockquote> - -Since column information is often only useful in the context of error handling, calculating the column -position can be performed when needed as opposed to doing it for each token. - -<H3><a name="ply_nn10"></a>3.7 Ignored characters</H3> - - -<p> -The special <tt>t_ignore</tt> rule is reserved by <tt>lex.py</tt> for characters -that should be completely ignored in the input stream. -Usually this is used to skip over whitespace and other non-essential characters. -Although it is possible to define a regular expression rule for whitespace in a manner -similar to <tt>t_newline()</tt>, the use of <tt>t_ignore</tt> provides substantially better -lexing performance because it is handled as a special case and is checked in a much -more efficient manner than the normal regular expression rules. - -<H3><a name="ply_nn11"></a>3.8 Literal characters</H3> - - -<p> -Literal characters can be specified by defining a variable <tt>literals</tt> in your lexing module. For example: - -<blockquote> -<pre> -literals = [ '+','-','*','/' ] -</pre> -</blockquote> - -or alternatively - -<blockquote> -<pre> -literals = "+-*/" -</pre> -</blockquote> - -A literal character is simply a single character that is returned "as is" when encountered by the lexer. Literals are checked -after all of the defined regular expression rules. Thus, if a rule starts with one of the literal characters, it will always -take precedence. -<p> -When a literal token is returned, both its <tt>type</tt> and <tt>value</tt> attributes are set to the character itself. For example, <tt>'+'</tt>. - -<H3><a name="ply_nn12"></a>3.9 Error handling</H3> - - -<p> -Finally, the <tt>t_error()</tt> -function is used to handle lexing errors that occur when illegal -characters are detected. In this case, the <tt>t.value</tt> attribute contains the -rest of the input string that has not been tokenized. In the example, the error function -was defined as follows: - -<blockquote> -<pre> -# Error handling rule -def t_error(t): - print "Illegal character '%s'" % t.value[0] - t.lexer.skip(1) -</pre> -</blockquote> - -In this case, we simply print the offending character and skip ahead one character by calling <tt>t.lexer.skip(1)</tt>. - -<H3><a name="ply_nn13"></a>3.10 Building and using the lexer</H3> - - -<p> -To build the lexer, the function <tt>lex.lex()</tt> is used. This function -uses Python reflection (or introspection) to read the the regular expression rules -out of the calling context and build the lexer. Once the lexer has been built, two functions can -be used to control the lexer. - -<ul> -<li><tt>lex.input(data)</tt>. Reset the lexer and store a new input string. -<li><tt>lex.token()</tt>. Return the next token. Returns a special <tt>LexToken</tt> instance on success or -None if the end of the input text has been reached. -</ul> - -If desired, the lexer can also be used as an object. The <tt>lex()</tt> returns a <tt>Lexer</tt> object that -can be used for this purpose.

However, it may also feel kind -of "hacky" to the purists. Just to put their mind at some ease, all -internal attributes of the lexer (with the exception of <tt>lineno</tt>) have names that are prefixed -by <tt>lex</tt> (e.g., <tt>lexdata</tt>,<tt>lexpos</tt>, etc.).

If you have the following code: - -<blockquote> -<pre> -m = MyLexer() -a = lex.lex(object=m) # Create a lexer - -b = a.clone() # Clone the lexer -</pre> -</blockquote> - -Then both <tt>a</tt> and <tt>b</tt> are going to be bound to the same -object <tt>m</tt>. If the object <tt>m</tt> contains internal state -related to lexing, this sharing may lead to quite a bit of confusion. To fix this, -the <tt>clone()</tt> method accepts an optional argument that can be used to supply a new object. This -can be used to clone the lexer and bind it to a new instance.

For instance, you may want the occurrence of a certain -token or syntactic construct to trigger a different kind of lexing. -PLY supports a feature that allows the underlying lexer to be put into -a series of different states. Each state can have its own tokens, -lexing rules, and so forth. The implementation is based largely on -the "start condition" feature of GNU flex. Details of this can be found -at <a -href="http://www.gnu.org/software/flex/manual/html_chapter/flex_11.html">http://www.gnu.org/software/flex/manual/html_chapter/flex_11.html.</a>. - -<p> -To define a new lexing state, it must first be declared. This is done by including a "states" declaration in your -lex file. For example: - -<blockquote> -<pre> -states = ( - ('foo','exclusive'), - ('bar','inclusive'), -) -</pre> -</blockquote> - -This declaration declares two states, <tt>'foo'</tt> -and <tt>'bar'</tt>. States may be of two types; <tt>'exclusive'</tt> -and <tt>'inclusive'</tt>. An exclusive state completely overrides the -default behavior of the lexer. That is, lex will only return tokens -and apply rules defined specifically for that state. An inclusive -state adds additional tokens and rules to the default set of rules. -Thus, lex will return both the tokens defined by default in addition -to those defined for the inclusive state. - -<p> -Once a state has been declared, tokens and rules are declared by including the -state name in token/rule declaration. For example: - -<blockquote> -<pre> -t_foo_NUMBER = r'\d+' # Token 'NUMBER' in state 'foo' -t_bar_ID = r'[a-zA-Z_][a-zA-Z0-9_]*' # Token 'ID' in state 'bar' - -def t_foo_newline(t): - r'\n' - t.lexer.lineno += 1 -</pre> -</blockquote> - -A token can be declared in multiple states by including multiple state names in the declaration. For example: - -<blockquote> -<pre> -t_foo_bar_NUMBER = r'\d+' # Defines token 'NUMBER' in both state 'foo' and 'bar' -</pre> -</blockquote> - -Alternative, a token can be declared in all states using the 'ANY' in the name. - -<blockquote> -<pre> -t_ANY_NUMBER = r'\d+' # Defines a token 'NUMBER' in all states -</pre> -</blockquote> - -If no state name is supplied, as is normally the case, the token is associated with a special state <tt>'INITIAL'</tt>. For example, -these two declarations are identical: - -<blockquote> -<pre> -t_NUMBER = r'\d+' -t_INITIAL_NUMBER = r'\d+' -</pre> -</blockquote> - -<p> -States are also associated with the special <tt>t_ignore</tt> and <tt>t_error()</tt> declarations. For example, if a state treats -these differently, you can declare: - -<blockquote> -<pre> -t_foo_ignore = " \t\n" # Ignored characters for state 'foo' - -def t_bar_error(t): # Special error handler for state 'bar' - pass -</pre> -</blockquote> - -By default, lexing operates in the <tt>'INITIAL'</tt> state. This state includes all of the normally defined tokens. -For users who aren't using different states, this fact is completely transparent. If, during lexing or parsing, you want to change -the lexing state, use the <tt>begin()</tt> method. For example: - -<blockquote> -<pre> -def t_begin_foo(t): - r'start_foo' - t.lexer.begin('foo') # Starts 'foo' state -</pre> -</blockquote> - -To get out of a state, you use <tt>begin()</tt> to switch back to the initial state. For example: - -<blockquote> -<pre> -def t_foo_end(t): - r'end_foo' - t.lexer.begin('INITIAL') # Back to the initial state -</pre> -</blockquote> - -The management of states can also be done with a stack. For example: - -<blockquote> -<pre> -def t_begin_foo(t): - r'start_foo' - t.lexer.push_state('foo') # Starts 'foo' state - -def t_foo_end(t): - r'end_foo' - t.lexer.pop_state() # Back to the previous state -</pre> -</blockquote> - -<p> -The use of a stack would be useful in situations where there are many ways of entering a new lexing state and you merely want to go back -to the previous state afterwards. - -<P> -An example might help clarify. Suppose you were writing a parser and you wanted to grab sections of arbitrary C code enclosed by -curly braces. That is, whenever you encounter a starting brace '{', you want to read all of the enclosed code up to the ending brace '}' -and return it as a string. Doing this with a normal regular expression rule is nearly (if not actually) impossible. This is because braces can -be nested and can be included in comments and strings. Thus, simply matching up to the first matching '}' character isn't good enough. Here is how -you might use lexer states to do this: - -<blockquote> -<pre> -# Declare the state -states = ( - ('ccode','exclusive'), -) - -# Match the first {. Enter ccode state. -def t_ccode(t): - r'\{' - t.lexer.code_start = t.lexer.lexpos # Record the starting position - t.lexer.level = 1 # Initial brace level - t.lexer.begin('ccode') # Enter 'ccode' state - -# Rules for the ccode state -def t_ccode_lbrace(t): - r'\{' - t.lexer.level +=1 - -def t_ccode_rbrace(t): - r'\}' - t.lexer.level -=1 - - # If closing brace, return the code fragment - if t.lexer.level == 0: - t.value = t.lexer.lexdata[t.lexer.code_start:t.lexer.lexpos+1] - t.type = "CCODE" - t.lexer.lineno += t.value.count('\n') - t.lexer.begin('INITIAL') - return t - -# C or C++ comment (ignore) -def t_ccode_comment(t): - r'(/\*(.|\n)*?*/)|(//.*)' - pass - -# C string -def t_ccode_string(t): - r'\"([^\\\n]|(\\.))*?\"' - -# C character literal -def t_ccode_char(t): - r'\'([^\\\n]|(\\.))*?\'' - -# Any sequence of non-whitespace characters (not braces, strings) -def t_ccode_nonspace(t): - r'[^\s\{\}\'\"]+' - -# Ignored characters (whitespace) -t_ccode_ignore = " \t\n" - -# For bad characters, we just skip over it -def t_ccode_error(t): - t.lexer.skip(1) -</pre> -</blockquote> - -In this example, the occurrence of the first '{' causes the lexer to record the starting position and enter a new state <tt>'ccode'</tt>. A collection of rules then match -various parts of the input that follow (comments, strings, etc.). All of these rules merely discard the token (by not returning a value). -However, if the closing right brace is encountered, the rule <tt>t_ccode_rbrace</tt> collects all of the code (using the earlier recorded starting -position), stores it, and returns a token 'CCODE' containing all of that text. When returning the token, the lexing state is restored back to its -initial state. - -<H3><a name="ply_nn21"></a>3.19 Miscellaneous Issues</H3> - - -<P> -<li>The lexer requires input to be supplied as a single input string. Since most machines have more than enough memory, this -rarely presents a performance concern. However, it means that the lexer currently can't be used with streaming data -such as open files or sockets.

Although -the lexer has been written to be as efficient as possible, it's not -blazingly fast when used on very large input files. If -performance is concern, you might consider upgrading to the most -recent version of Python, creating a hand-written lexer, or offloading -the lexer into a C extension module. - -<p> -If you are going to create a hand-written lexer and you plan to use it with <tt>yacc.py</tt>, -it only needs to conform to the following requirements: - -<ul> -<li>It must provide a <tt>token()</tt> method that returns the next token or <tt>None</tt> if no more -tokens are available. -<li>The <tt>token()</tt> method must return an object <tt>tok</tt> that has <tt>type</tt> and <tt>value</tt> attributes. -</ul> - -<H2><a name="ply_nn22"></a>4. Parsing basics</H2> - - -<tt>yacc.py</tt> is used to parse language syntax. Before showing an -example, there are a few important bits of background that must be -mentioned. First, <em>syntax</em> is usually specified in terms of a BNF grammar. -For example, if you wanted to parse -simple arithmetic expressions, you might first write an unambiguous -grammar specification like this: - -<blockquote> -<pre> -expression : expression + term - | expression - term - | term - -term : term * factor - | term / factor - | factor - -factor : NUMBER - | ( expression ) -</pre> -</blockquote> - -In the grammar, symbols such as <tt>NUMBER</tt>, <tt>+</tt>, <tt>-</tt>, <tt>*</tt>, and <tt>/</tt> are known -as <em>terminals</em> and correspond to raw input tokens. Identifiers such as <tt>term</tt> and <tt>factor</tt> refer to more -complex rules, typically comprised of a collection of tokens. These identifiers are known as <em>non-terminals</em>. -<P> -The semantic behavior of a language is often specified using a -technique known as syntax directed translation. In syntax directed -translation, attributes are attached to each symbol in a given grammar -rule along with an action. Whenever a particular grammar rule is -recognized, the action describes what to do. For example, given the -expression grammar above, you might write the specification for a -simple calculator like this: - -<blockquote> -<pre> -Grammar Action --------------------------------- -------------------------------------------- -expression0 : expression1 + term expression0.val = expression1.val + term.val - | expression1 - term expression0.val = expression1.val - term.val - | term expression0.val = term.val - -term0 : term1 * factor term0.val = term1.val * factor.val - | term1 / factor term0.val = term1.val / factor.val - | factor term0.val = factor.val - -factor : NUMBER factor.val = int(NUMBER.lexval) - | ( expression ) factor.val = expression.val -</pre> -</blockquote> - -A good way to think about syntax directed translation is to simply think of each symbol in the grammar as some -kind of object. The semantics of the language are then expressed as a collection of methods/operations on these -objects. - -<p> -Yacc uses a parsing technique known as LR-parsing or shift-reduce parsing. LR parsing is a -bottom up technique that tries to recognize the right-hand-side of various grammar rules. -Whenever a valid right-hand-side is found in the input, the appropriate action code is triggered and the -grammar symbols are replaced by the grammar symbol on the left-hand-side. - -<p> -LR parsing is commonly implemented by shifting grammar symbols onto a stack and looking at the stack and the next -input token for patterns. The details of the algorithm can be found in a compiler text, but the -following example illustrates the steps that are performed if you wanted to parse the expression -<tt>3 + 5 * (10 - 20)</tt> using the grammar defined above: - -<blockquote> -<pre> -Step Symbol Stack Input Tokens Action ----- --------------------- --------------------- ------------------------------- -1 $ 3 + 5 * ( 10 - 20 )$ Shift 3 -2 $ 3 + 5 * ( 10 - 20 )$ Reduce factor : NUMBER -3 $ factor + 5 * ( 10 - 20 )$ Reduce term : factor -4 $ term + 5 * ( 10 - 20 )$ Reduce expr : term -5 $ expr + 5 * ( 10 - 20 )$ Shift + -6 $ expr + 5 * ( 10 - 20 )$ Shift 5 -7 $ expr + 5 * ( 10 - 20 )$ Reduce factor : NUMBER -8 $ expr + factor * ( 10 - 20 )$ Reduce term : factor -9 $ expr + term * ( 10 - 20 )$ Shift * -10 $ expr + term * ( 10 - 20 )$ Shift ( -11 $ expr + term * ( 10 - 20 )$ Shift 10 -12 $ expr + term * ( 10 - 20 )$ Reduce factor : NUMBER -13 $ expr + term * ( factor - 20 )$ Reduce term : factor -14 $ expr + term * ( term - 20 )$ Reduce expr : term -15 $ expr + term * ( expr - 20 )$ Shift - -16 $ expr + term * ( expr - 20 )$ Shift 20 -17 $ expr + term * ( expr - 20 )$ Reduce factor : NUMBER -18 $ expr + term * ( expr - factor )$ Reduce term : factor -19 $ expr + term * ( expr - term )$ Reduce expr : expr - term -20 $ expr + term * ( expr )$ Shift ) -21 $ expr + term * ( expr ) $ Reduce factor : (expr) -22 $ expr + term * factor $ Reduce term : term * factor -23 $ expr + term $ Reduce expr : expr + term -24 $ expr $ Reduce expr -25 $ $ Success! -</pre> -</blockquote> - -When parsing the expression, an underlying state machine and the current input token determine what to do next. -If the next token looks like part of a valid grammar rule (based on other items on the stack), it is generally shifted -onto the stack. If the top of the stack contains a valid right-hand-side of a grammar rule, it is -usually "reduced" and the symbols replaced with the symbol on the left-hand-side. When this reduction occurs, the -appropriate action is triggered (if defined). If the input token can't be shifted and the top of stack doesn't match -any grammar rules, a syntax error has occurred and the parser must take some kind of recovery step (or bail out). - -<p> -It is important to note that the underlying implementation is built around a large finite-state machine that is encoded -in a collection of tables. The construction of these tables is quite complicated and beyond the scope of this discussion. -However, subtle details of this process explain why, in the example above, the parser chooses to shift a token -onto the stack in step 9 rather than reducing the rule <tt>expr : expr + term</tt>. - -<H2><a name="ply_nn23"></a>5.

This is required. -from calclex import tokens - -def p_expression_plus(p): - 'expression : expression PLUS term' - p[0] = p[1] + p[3] - -def p_expression_minus(p): - 'expression : expression MINUS term' - p[0] = p[1] - p[3] - -def p_expression_term(p): - 'expression : term' - p[0] = p[1] - -def p_term_times(p): - 'term : term TIMES factor' - p[0] = p[1] * p[3] - -def p_term_div(p): - 'term : term DIVIDE factor' - p[0] = p[1] / p[3] - -def p_term_factor(p): - 'term : factor' - p[0] = p[1] - -def p_factor_num(p): - 'factor : NUMBER' - p[0] = p[1] - -def p_factor_expr(p): - 'factor : LPAREN expression RPAREN' - p[0] = p[2] - -# Error rule for syntax errors -def p_error(p): - print "Syntax error in input!" - -# Build the parser -yacc.yacc() - -# Use this if you want to build the parser using SLR instead of LALR -# yacc.yacc(method="SLR") - -while 1: - try: - s = raw_input('calc > ') - except EOFError: - break - if not s: continue - result = yacc.parse(s) - print result -</pre> -</blockquote> - -In this example, each grammar rule is defined by a Python function where the docstring to that function contains the -appropriate context-free grammar specification. Each function accepts a single -argument <tt>p</tt> that is a sequence containing the values of each grammar symbol in the corresponding rule. The values of -<tt>p[i]</tt> are mapped to grammar symbols as shown here: - -<blockquote> -<pre> -def p_expression_plus(p): - 'expression : expression PLUS term' - # ^ ^ ^ ^ - # p[0] p[1] p[2] p[3] - - p[0] = p[1] + p[3] -</pre> -</blockquote> - -For tokens, the "value" of the corresponding <tt>p[i]</tt> is the -<em>same</em> as the <tt>p.value</tt> attribute assigned -in the lexer module. For non-terminals, the value is determined by -whatever is placed in <tt>p[0]</tt> when rules are reduced. This -value can be anything at all. However, it probably most common for -the value to be a simple Python type, a tuple, or an instance. In this example, we -are relying on the fact that the <tt>NUMBER</tt> token stores an integer value in its value -field. All of the other rules simply perform various types of integer operations and store -the result. - -<P> -Note: The use of negative indices have a special meaning in yacc---specially <tt>p[-1]</tt> does -not have the same value as <tt>p[3]</tt> in this example. Please see the section on "Embedded Actions" for further -details. - -<p> -The first rule defined in the yacc specification determines the starting grammar -symbol (in this case, a rule for <tt>expression</tt> appears first). Whenever -the starting rule is reduced by the parser and no more input is available, parsing -stops and the final value is returned (this value will be whatever the top-most rule -placed in <tt>p[0]</tt>). Note: an alternative starting symbol can be specified using the <tt>start</tt> keyword argument to -<tt>yacc()</tt>. - -<p>The <tt>p_error(p)</tt> rule is defined to catch syntax errors. See the error handling section -below for more detail. - -<p> -To build the parser, call the <tt>yacc.yacc()</tt> function. This function -looks at the module and attempts to construct all of the LR parsing tables for the grammar -you have specified. The first time <tt>yacc.yacc()</tt> is invoked, you will get a message -such as this: - -<blockquote> -<pre> -$ python calcparse.py -yacc: Generating LALR parsing table... -calc > -</pre> -</blockquote> - -Since table construction is relatively expensive (especially for large -grammars), the resulting parsing table is written to the current -directory in a file called <tt>parsetab.py</tt>. In addition, a -debugging file called <tt>parser.out</tt> is created. On subsequent -executions, <tt>yacc</tt> will reload the table from -<tt>parsetab.py</tt> unless it has detected a change in the underlying -grammar (in which case the tables and <tt>parsetab.py</tt> file are -regenerated). Note: The names of parser output files can be changed if necessary. See the notes that follow later. - -<p> -If any errors are detected in your grammar specification, <tt>yacc.py</tt> will produce -diagnostic messages and possibly raise an exception. Some of the errors that can be detected include: - -<ul> -<li>Duplicated function names (if more than one rule function have the same name in the grammar file). -<li>Shift/reduce and reduce/reduce conflicts generated by ambiguous grammars. -<li>Badly specified grammar rules. -<li>Infinite recursion (rules that can never terminate). -<li>Unused rules and tokens -<li>Undefined rules and tokens -</ul> - -The next few sections now discuss a few finer points of grammar construction. - -<H3><a name="ply_nn25"></a>5.2 Combining Grammar Rule Functions</H3> - - -When grammar rules are similar, they can be combined into a single function. -For example, consider the two rules in our earlier example: - -<blockquote> -<pre> -def p_expression_plus(p): - 'expression : expression PLUS term' - p[0] = p[1] + p[3] - -def p_expression_minus(t): - 'expression : expression MINUS term' - p[0] = p[1] - p[3] -</pre> -</blockquote> - -Instead of writing two functions, you might write a single function like this: - -<blockquote> -<pre> -def p_expression(p): - '''expression : expression PLUS term - | expression MINUS term''' - if p[2] == '+': - p[0] = p[1] + p[3] - elif p[2] == '-': - p[0] = p[1] - p[3] -</pre> -</blockquote> - -In general, the doc string for any given function can contain multiple grammar rules. So, it would -have also been legal (although possibly confusing) to write this: - -<blockquote> -<pre> -def p_binary_operators(p): - '''expression : expression PLUS term - | expression MINUS term - term : term TIMES factor - | term DIVIDE factor''' - if p[2] == '+': - p[0] = p[1] + p[3] - elif p[2] == '-': - p[0] = p[1] - p[3] - elif p[2] == '*': - p[0] = p[1] * p[3] - elif p[2] == '/': - p[0] = p[1] / p[3] -</pre> -</blockquote> - -When combining grammar rules into a single function, it is usually a good idea for all of the rules to have -a similar structure (e.g., the same number of terms). Otherwise, the corresponding action code may be more -complicated than necessary. However, it is possible to handle simple cases using len(). For example: - -<blockquote> -<pre> -def p_expressions(p): - '''expression : expression MINUS expression - | MINUS expression''' - if (len(p) == 4): - p[0] = p[1] - p[3] - elif (len(p) == 3): - p[0] = -p[2] -</pre> -</blockquote> - -<H3><a name="ply_nn26"></a>5.3 Character Literals</H3> - - -If desired, a grammar may contain tokens defined as single character literals. For example: - -<blockquote> -<pre> -def p_binary_operators(p): - '''expression : expression '+' term - | expression '-' term - term : term '*' factor - | term '/' factor''' - if p[2] == '+': - p[0] = p[1] + p[3] - elif p[2] == '-': - p[0] = p[1] - p[3] - elif p[2] == '*': - p[0] = p[1] * p[3] - elif p[2] == '/': - p[0] = p[1] / p[3] -</pre> -</blockquote> - -A character literal must be enclosed in quotes such as <tt>'+'</tt>. In addition, if literals are used, they must be declared in the -corresponding <tt>lex</tt> file through the use of a special <tt>literals</tt> declaration. - -<blockquote> -<pre> -# Literals. Should be placed in module given to lex() -literals = ['+','-','*','/' ] -</pre> -</blockquote> - -<b>Character literals are limited to a single character</b>. Thus, it is not legal to specify literals such as <tt>'<='</tt> or <tt>'=='</tt>. For this, use -the normal lexing rules (e.g., define a rule such as <tt>t_EQ = r'=='</tt>). - -<H3><a name="ply_nn26"></a>5.4 Empty Productions</H3> - - -<tt>yacc.py</tt> can handle empty productions by defining a rule like this: - -<blockquote> -<pre> -def p_empty(p): - 'empty :' - pass -</pre> -</blockquote> - -Now to use the empty production, simply use 'empty' as a symbol. For example: - -<blockquote> -<pre> -def p_optitem(p): - 'optitem : item' - ' | empty' - ... -</pre> -</blockquote> - -Note: You can write empty rules anywhere by simply specifying an empty right hand side. However, I personally find that -writing an "empty" rule and using "empty" to denote an empty production is easier to read. - -<H3><a name="ply_nn28"></a>5.5 Changing the starting symbol</H3> - - -Normally, the first rule found in a yacc specification defines the starting grammar rule (top level rule). To change this, simply -supply a <tt>start</tt> specifier in your file. For example: - -<blockquote> -<pre> -start = 'foo' - -def p_bar(p): - 'bar : A B' - -# This is the starting rule due to the start specifier above -def p_foo(p): - 'foo : bar X' -... -</pre> -</blockquote> - -The use of a <tt>start</tt> specifier may be useful during debugging since you can use it to have yacc build a subset of -a larger grammar. For this purpose, it is also possible to specify a starting symbol as an argument to <tt>yacc()</tt>. For example: - -<blockquote> -<pre> -yacc.yacc(start='foo') -</pre> -</blockquote> - -<H3><a name="ply_nn27"></a>5.6 Dealing With Ambiguous Grammars</H3> - - -The expression grammar given in the earlier example has been written in a special format to eliminate ambiguity. -However, in many situations, it is extremely difficult or awkward to write grammars in this format. A -much more natural way to express the grammar is in a more compact form like this: - -<blockquote> -<pre> -expression : expression PLUS expression - | expression MINUS expression - | expression TIMES expression - | expression DIVIDE expression - | LPAREN expression RPAREN - | NUMBER -</pre> -</blockquote> - -Unfortunately, this grammar specification is ambiguous. For example, if you are parsing the string -"3 * 4 + 5", there is no way to tell how the operators are supposed to be grouped. -For example, does the expression mean "(3 * 4) + 5" or is it "3 * (4+5)"? - -<p> -When an ambiguous grammar is given to <tt>yacc.py</tt> it will print messages about "shift/reduce conflicts" -or a "reduce/reduce conflicts". A shift/reduce conflict is caused when the parser generator can't decide -whether or not to reduce a rule or shift a symbol on the parsing stack. For example, consider -the string "3 * 4 + 5" and the internal parsing stack: - -<blockquote> -<pre> -Step Symbol Stack Input Tokens Action ----- --------------------- --------------------- ------------------------------- -1 $ 3 * 4 + 5$ Shift 3 -2 $ 3 * 4 + 5$ Reduce : expression : NUMBER -3 $ expr * 4 + 5$ Shift * -4 $ expr * 4 + 5$ Shift 4 -5 $ expr * 4 + 5$ Reduce: expression : NUMBER -6 $ expr * expr + 5$ SHIFT/REDUCE CONFLICT ???? -</pre> -</blockquote> - -In this case, when the parser reaches step 6, it has two options. One is to reduce the -rule <tt>expr : expr * expr</tt> on the stack. The other option is to shift the -token <tt>+</tt> on the stack. Both options are perfectly legal from the rules -of the context-free-grammar. - -<p> -By default, all shift/reduce conflicts are resolved in favor of shifting. Therefore, in the above -example, the parser will always shift the <tt>+</tt> instead of reducing. Although this -strategy works in many cases (including the ambiguous if-then-else), it is not enough for arithmetic -expressions. In fact, in the above example, the decision to shift <tt>+</tt> is completely wrong---we should have -reduced <tt>expr * expr</tt> since multiplication has higher mathematical precedence than addition. - -<p>To resolve ambiguity, especially in expression grammars, <tt>yacc.py</tt> allows individual -tokens to be assigned a precedence level and associativity. This is done by adding a variable -<tt>precedence</tt> to the grammar file like this: - -<blockquote> -<pre> -precedence = ( - ('left', 'PLUS', 'MINUS'), - ('left', 'TIMES', 'DIVIDE'), -) -</pre> -</blockquote> - -This declaration specifies that <tt>PLUS</tt>/<tt>MINUS</tt> have -the same precedence level and are left-associative and that -<tt>TIMES</tt>/<tt>DIVIDE</tt> have the same precedence and are left-associative. -Within the <tt>precedence</tt> declaration, tokens are ordered from lowest to highest precedence. Thus, -this declaration specifies that <tt>TIMES</tt>/<tt>DIVIDE</tt> have higher -precedence than <tt>PLUS</tt>/<tt>MINUS</tt> (since they appear later in the -precedence specification). - -<p> -The precedence specification works by associating a numerical precedence level value and associativity direction to -the listed tokens. For example, in the above example you get: - -<blockquote> -<pre> -PLUS : level = 1, assoc = 'left' -MINUS : level = 1, assoc = 'left' -TIMES : level = 2, assoc = 'left' -DIVIDE : level = 2, assoc = 'left' -</pre> -</blockquote> - -These values are then used to attach a numerical precedence value and associativity direction -to each grammar rule. <em>This is always determined by looking at the precedence of the right-most terminal symbol.</em> -For example: - -<blockquote> -<pre> -expression : expression PLUS expression # level = 1, left - | expression MINUS expression # level = 1, left - | expression TIMES expression # level = 2, left - | expression DIVIDE expression # level = 2, left - | LPAREN expression RPAREN # level = None (not specified) - | NUMBER # level = None (not specified) -</pre> -</blockquote> - -When shift/reduce conflicts are encountered, the parser generator resolves the conflict by -looking at the precedence rules and associativity specifiers. - -<p> -<ol> -<li>If the current token has higher precedence, it is shifted. -<li>If the grammar rule on the stack has higher precedence, the rule is reduced. -<li>If the current token and the grammar rule have the same precedence, the -rule is reduced for left associativity, whereas the token is shifted for right associativity. -<li>If nothing is known about the precedence, shift/reduce conflicts are resolved in -favor of shifting (the default). -</ol> - -For example, if "expression PLUS expression" has been parsed and the next token -is "TIMES", the action is going to be a shift because "TIMES" has a higher precedence level than "PLUS". On the other -hand, if "expression TIMES expression" has been parsed and the next token is "PLUS", the action -is going to be reduce because "PLUS" has a lower precedence than "TIMES." - -<p> -When shift/reduce conflicts are resolved using the first three techniques (with the help of -precedence rules), <tt>yacc.py</tt> will report no errors or conflicts in the grammar. - -<p> -One problem with the precedence specifier technique is that it is sometimes necessary to -change the precedence of an operator in certain contents. For example, consider a unary-minus operator -in "3 + 4 * -5". Normally, unary minus has a very high precedence--being evaluated before the multiply. -However, in our precedence specifier, MINUS has a lower precedence than TIMES. To deal with this, -precedence rules can be given for fictitious tokens like this: - -<blockquote> -<pre> -precedence = ( - ('left', 'PLUS', 'MINUS'), - ('left', 'TIMES', 'DIVIDE'), - ('right', 'UMINUS'), # Unary minus operator -) -</pre> -</blockquote> - -Now, in the grammar file, we can write our unary minus rule like this: - -<blockquote> -<pre> -def p_expr_uminus(p): - 'expression : MINUS expression %prec UMINUS' - p[0] = -p[2] -</pre> -</blockquote> - -In this case, <tt>%prec UMINUS</tt> overrides the default rule precedence--setting it to that -of UMINUS in the precedence specifier. - -<p> -At first, the use of UMINUS in this example may appear very confusing. -UMINUS is not an input token or a grammer rule. Instead, you should -think of it as the name of a special marker in the precedence table. When you use the <tt>%prec</tt> qualifier, you're simply -telling yacc that you want the precedence of the expression to be the same as for this special marker instead of the usual precedence. - -<p> -It is also possible to specify non-associativity in the <tt>precedence</tt> table. This would -be used when you <em>don't</em> want operations to chain together. For example, suppose -you wanted to support comparison operators like <tt><</tt> and <tt>></tt> but you didn't want to allow -combinations like <tt>a < b < c</tt>. To do this, simply specify a rule like this: - -<blockquote> -<pre> -precedence = ( - ('nonassoc', 'LESSTHAN', 'GREATERTHAN'), # Nonassociative operators - ('left', 'PLUS', 'MINUS'), - ('left', 'TIMES', 'DIVIDE'), - ('right', 'UMINUS'), # Unary minus operator -) -</pre> -</blockquote> - -<p> -If you do this, the occurrence of input text such as <tt> a < b < c</tt> will result in a syntax error. However, simple -expressions such as <tt>a < b</tt> will still be fine. - -<p> -Reduce/reduce conflicts are caused when there are multiple grammar -rules that can be applied to a given set of symbols. This kind of -conflict is almost always bad and is always resolved by picking the -rule that appears first in the grammar file. Reduce/reduce conflicts -are almost always caused when different sets of grammar rules somehow -generate the same set of symbols. For example: - -<blockquote> -<pre> -assignment : ID EQUALS NUMBER - | ID EQUALS expression - -expression : expression PLUS expression - | expression MINUS expression - | expression TIMES expression - | expression DIVIDE expression - | LPAREN expression RPAREN - | NUMBER -</pre> -</blockquote> - -In this case, a reduce/reduce conflict exists between these two rules: - -<blockquote> -<pre> -assignment : ID EQUALS NUMBER -expression : NUMBER -</pre> -</blockquote> - -For example, if you wrote "a = 5", the parser can't figure out if this -is supposed to be reduced as <tt>assignment : ID EQUALS NUMBER</tt> or -whether it's supposed to reduce the 5 as an expression and then reduce -the rule <tt>assignment : ID EQUALS expression</tt>. - -<p> -It should be noted that reduce/reduce conflicts are notoriously difficult to spot -simply looking at the input grammer. To locate these, it is usually easier to look at the -<tt>parser.out</tt> debugging file with an appropriately high level of caffeination. - -<H3><a name="ply_nn28"></a>5.7 The parser.out file</H3> - - -Tracking down shift/reduce and reduce/reduce conflicts is one of the finer pleasures of using an LR -parsing algorithm. To assist in debugging, <tt>yacc.py</tt> creates a debugging file called -'parser.out' when it generates the parsing table. The contents of this file look like the following: - -<blockquote> -<pre> -Unused terminals: - - -Grammar - -Rule 1 expression -> expression PLUS expression -Rule 2 expression -> expression MINUS expression -Rule 3 expression -> expression TIMES expression -Rule 4 expression -> expression DIVIDE expression -Rule 5 expression -> NUMBER -Rule 6 expression -> LPAREN expression RPAREN - -Terminals, with rules where they appear - -TIMES : 3 -error : -MINUS : 2 -RPAREN : 6 -LPAREN : 6 -DIVIDE : 4 -PLUS : 1 -NUMBER : 5 - -Nonterminals, with rules where they appear - -expression : 1 1 2 2 3 3 4 4 6 0 - - -Parsing method: LALR - - -state 0 - - S' -> . expression - expression -> . expression PLUS expression - expression -> . expression MINUS expression - expression -> . expression TIMES expression - expression -> . expression DIVIDE expression - expression -> .

Error recovery in LR parsers is a delicate -topic that involves ancient rituals and black-magic. The recovery mechanism -provided by <tt>yacc.py</tt> is comparable to Unix yacc so you may want -consult a book like O'Reilly's "Lex and Yacc" for some of the finer details. - -<p> -When a syntax error occurs, <tt>yacc.py</tt> performs the following steps: - -<ol> -<li>On the first occurrence of an error, the user-defined <tt>p_error()</tt> function -is called with the offending token as an argument. Afterwards, the parser enters -an "error-recovery" mode in which it will not make future calls to <tt>p_error()</tt> until it -has successfully shifted at least 3 tokens onto the parsing stack. - -<p> -<li>If no recovery action is taken in <tt>p_error()</tt>, the offending lookahead token is replaced -with a special <tt>error</tt> token. - -<p> -<li>If the offending lookahead token is already set to <tt>error</tt>, the top item of the parsing stack is -deleted. - -<p> -<li>If the entire parsing stack is unwound, the parser enters a restart state and attempts to start -parsing from its initial state. - -<p> -<li>If a grammar rule accepts <tt>error</tt> as a token, it will be -shifted onto the parsing stack. - -<p> -<li>If the top item of the parsing stack is <tt>error</tt>, lookahead tokens will be discarded until the -parser can successfully shift a new symbol or reduce a rule involving <tt>error</tt>. -</ol> - -<H4><a name="ply_nn30"></a>5.8.1 Recovery and resynchronization with error rules</H4> - - -The most well-behaved approach for handling syntax errors is to write grammar rules that include the <tt>error</tt> -token. For example, suppose your language had a grammar rule for a print statement like this: - -<blockquote> -<pre> -def p_statement_print(p): - 'statement : PRINT expr SEMI' - ... -</pre> -</blockquote> - -To account for the possibility of a bad expression, you might write an additional grammar rule like this: - -<blockquote> -<pre> -def p_statement_print_error(p): - 'statement : PRINT error SEMI' - print "Syntax error in print statement. Bad expression" - -</pre> -</blockquote> - -In this case, the <tt>error</tt> token will match any sequence of -tokens that might appear up to the first semicolon that is -encountered. Once the semicolon is reached, the rule will be -invoked and the <tt>error</tt> token will go away. - -<p> -This type of recovery is sometimes known as parser resynchronization. -The <tt>error</tt> token acts as a wildcard for any bad input text and -the token immediately following <tt>error</tt> acts as a -synchronization token. - -<p> -It is important to note that the <tt>error</tt> token usually does not appear as the last token -on the right in an error rule. For example: - -<blockquote> -<pre> -def p_statement_print_error(p): - 'statement : PRINT error' - print "Syntax error in print statement.

However, such -construction is easy enough to do on your own. Simply create a data structure for abstract syntax tree nodes -and assign nodes to <tt>p[0]</tt> in each rule. - -For example: - -<blockquote> -<pre> -class Expr: pass - -class BinOp(Expr): - def __init__(self,left,op,right): - self.type = "binop" - self.left = left - self.right = right - self.op = op - -class Number(Expr): - def __init__(self,value): - self.type = "number" - self.value = value - -def p_expression_binop(p): - '''expression : expression PLUS expression - | expression MINUS expression - | expression TIMES expression - | expression DIVIDE expression''' - - p[0] = BinOp(p[1],p[2],p[3]) - -def p_expression_group(p): - 'expression : LPAREN expression RPAREN' - p[0] = p[2] - -def p_expression_number(p): - 'expression : NUMBER' - p[0] = Number(p[1]) -</pre> -</blockquote> - -To simplify tree traversal, it may make sense to pick a very generic tree structure for your parse tree nodes. -For example: - -<blockquote> -<pre> -class Node: - def __init__(self,type,children=None,leaf=None): - self.type = type - if children: - self.children = children - else: - self.children = [ ] - self.leaf = leaf - -def p_expression_binop(p): - '''expression : expression PLUS expression - | expression MINUS expression - | expression TIMES expression - | expression DIVIDE expression''' - - p[0] = Node("binop", [p[1],p[3]], p[2]) -</pre> -</blockquote> - -<H3><a name="ply_nn35"></a>5.11 Embedded Actions</H3> - - -The parsing technique used by yacc only allows actions to be executed at the end of a rule. For example, -suppose you have a rule like this: - -<blockquote> -<pre> -def p_foo(p): - "foo : A B C D" - print "Parsed a foo", p[1],p[2],p[3],p[4] -</pre> -</blockquote> - -<p> -In this case, the supplied action code only executes after all of the -symbols <tt>A</tt>, <tt>B</tt>, <tt>C</tt>, and <tt>D</tt> have been -parsed. Sometimes, however, it is useful to execute small code -fragments during intermediate stages of parsing. For example, suppose -you wanted to perform some action immediately after <tt>A</tt> has -been parsed. To do this, you can write a empty rule like this: - -<blockquote> -<pre> -def p_foo(p): - "foo : A seen_A B C D" - print "Parsed a foo", p[1],p[3],p[4],p[5] - print "seen_A returned", p[2] - -def p_seen_A(p): - "seen_A :" - print "Saw an A = ", p[-1] # Access grammar symbol to left - p[0] = some_value # Assign value to seen_A - -</pre> -</blockquote> - -<p> -In this example, the empty <tt>seen_A</tt> rule executes immediately -after <tt>A</tt> is shifted onto the parsing stack. Within this -rule, <tt>p[-1]</tt> refers to the symbol on the stack that appears -immediately to the left of the <tt>seen_A</tt> symbol. In this case, -it would be the value of <tt>A</tt> in the <tt>foo</tt> rule -immediately above. Like other rules, a value can be returned from an -embedded action by simply assigning it to <tt>p[0]</tt> - -<p> -The use of embedded actions can sometimes introduce extra shift/reduce conflicts. For example, -this grammar has no conflicts: - -<blockquote> -<pre> -def p_foo(p): - """foo : abcd - | abcx""" - -def p_abcd(p): - "abcd : A B C D" - -def p_abcx(p): - "abcx : A B C X" -</pre> -</blockquote> - -However, if you insert an embedded action into one of the rules like this, - -<blockquote> -<pre> -def p_foo(p): - """foo : abcd - | abcx""" - -def p_abcd(p): - "abcd : A B C D" - -def p_abcx(p): - "abcx : A B seen_AB C X" - -def p_seen_AB(p): - "seen_AB :" -</pre> -</blockquote> - -an extra shift-reduce conflict will be introduced. This conflict is caused by the fact that the same symbol <tt>C</tt> appears next in -both the <tt>abcd</tt> and <tt>abcx</tt> rules. The parser can either shift the symbol (<tt>abcd</tt> rule) or reduce the empty rule <tt>seen_AB</tt> (<tt>abcx</tt> rule). - -<p> -A common use of embedded rules is to control other aspects of parsing -such as scoping of local variables. For example, if you were parsing C code, you might -write code like this: - -<blockquote> -<pre> -def p_statements_block(p): - "statements: LBRACE new_scope statements RBRACE""" - # Action code - ... - pop_scope() # Return to previous scope - -def p_new_scope(p): - "new_scope :" - # Create a new scope for local variables - s = new_scope() - push_scope(s) - ... -</pre> -</blockquote> - -In this case, the embedded action <tt>new_scope</tt> executes immediately after a <tt>LBRACE</tt> (<tt>{</tt>) symbol is parsed. This might -adjust internal symbol tables and other aspects of the parser. Upon completion of the rule <tt>statements_block</tt>, code might undo the operations performed in the embedded action (e.g., <tt>pop_scope()</tt>). - -<H3><a name="ply_nn36"></a>5.12 Yacc implementation notes</H3> - - -<ul> -<li>The default parsing method is LALR.

There is no -difference in actual parsing performance---the same code is used in both cases. LALR is preferred when working -with more complicated grammars since it is more powerful. - -<p> - -<li>By default, <tt>yacc.py</tt> relies on <tt>lex.py</tt> for tokenizing. However, an alternative tokenizer -can be supplied as follows: - -<blockquote> -<pre> -yacc.parse(lexer=x) -</pre> -</blockquote> -in this case, <tt>x</tt> must be a Lexer object that minimally has a <tt>x.token()</tt> method for retrieving the next -token. If an input string is given to <tt>yacc.parse()</tt>, the lexer must also have an <tt>x.input()</tt> method. - -<p> -<li>By default, the yacc generates tables in debugging mode (which produces the parser.out file and other output). -To disable this, use - -<blockquote> -<pre> -yacc.yacc(debug=0) -</pre> -</blockquote> - -<p> -<li>To change the name of the <tt>parsetab.py</tt> file, use: - -<blockquote> -<pre> -yacc.yacc(tabmodule="foo") -</pre> -</blockquote> - -<p> -<li>To change the directory in which the <tt>parsetab.py</tt> file (and other output files) are written, use: -<blockquote> -<pre> -yacc.yacc(tabmodule="foo",outputdir="somedirectory") -</pre> -</blockquote> - -<p> -<li>To prevent yacc from generating any kind of parser table file, use: -<blockquote> -<pre> -yacc.yacc(write_tables=0) -</pre> -</blockquote> - -Note: If you disable table generation, yacc() will regenerate the parsing tables -each time it runs (which may take awhile depending on how large your grammar is). - -<P> -<li>To print copious amounts of debugging during parsing, use: - -<blockquote> -<pre> -yacc.parse(debug=1) -</pre> -</blockquote> - -<p> -<li>To redirect the debugging output to a filename of your choosing, use: - -<blockquote> -<pre> -yacc.parse(debug=1, debugfile="debugging.out") -</pre> -</blockquote> - -<p> -<li>The <tt>yacc.yacc()</tt> function really returns a parser object.

The decision to regenerate the tables is determined by taking an MD5 -checksum of all grammar rules and precedence rules.

For more complex languages such as C, table generation may take 30-60 seconds on a slow -machine.

The grammer is specified by supplying the BNF inside -# Python documentation strings. The inspiration for this technique was borrowed -# from John Aycock's Spark parsing system. PLY might be viewed as cross between -# Spark and the GNU bison utility. -# -# The current implementation is only somewhat object-oriented. The -# LR parser itself is defined in terms of an object (which allows multiple -# parsers to co-exist). However, most of the variables used during table -# construction are defined in terms of global variables. Users shouldn't -# notice unless they are trying to define multiple parsers at the same -# time using threads (in which case they should have their head examined). -# -# This implementation supports both SLR and LALR(1) parsing. LALR(1) -# support was originally implemented by Elias Ioup (ezioup@alumni.uchicago.edu), -# using the algorithm found in Aho, Sethi, and Ullman "Compilers: Principles, -# Techniques, and Tools" (The Dragon Book). LALR(1) has since been replaced -# by the more efficient DeRemer and Pennello algorithm. -# -# :::::::: WARNING ::::::: -# -# Construction of LR parsing tables is fairly complicated and expensive. -# To make this module run fast, a *LOT* of work has been put into -# optimization---often at the expensive of readability and what might -# consider to be good Python "coding style."
