Here are a few highlights: + + - PLY is 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 LALR(1) + algorithm used in 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. People have used PLY to build parsers for + C, C++, ADA, and other real programming languages. + +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 2.2 or greater. However, you should +use the latest Python release if possible. It should work on just +about any platform. PLY has been tested with both CPython and Jython. +It also seems to 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-3.0 +======================== +PLY-3.0 the first PLY release to support Python 3. However, backwards +compatibility with Python 2.2 is still preserved. PLY provides dual +Python 2/3 compatibility by restricting its implementation to a common +subset of basic language features. You should not convert PLY using +2to3--it is not necessary and may in fact break the implementation. + +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+' + t.value = int(t.value) + 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 > ') # use input() on Python 3 + except EOFError: + break + yacc.parse(s) + + +Bug Reports and Patches +======================= +My goal with PLY is to simply have a decent lex/yacc implementation +for Python.

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."
