py-ply: updated to 3.11
Version 3.11
------------
Fixed some minor bugs related to re flags and token order.
Added a set_lexpos() method to grammar symbols.
Mostly minor bug fixes and small code cleanups.
Version 3.10
------------
Changed grammar signature computation to not involve hashing
functions. Parts are just combined into a big string.
Fixed Issue 101: Incorrect shift-reduce conflict resolution with
precedence specifier.
PLY was incorrectly resolving shift-reduce conflicts in certain
cases. For example, in the example/calc/calc.py example, you
could trigger it doing this:
calc > -3 - 4
1 (correct answer should be -7)
calc >
Issue and suggested patch contributed by https://github.com/RomaVis
Version 3.9
-----------
Exposed the parser state number as the parser.state attribute
in productions and error functions. For example:
def p_somerule(p):
'''
rule : A B C
'''
print('State:', p.parser.state)
May address issue 65 (publish current state in error callback).
Fixed Issue 88. Python3 compatibility with ply/cpp.
Fixed Issue 93. Ply can crash if SyntaxError is raised inside
a production. Not actually sure if the original implementation
worked as documented at all. Yacc has been modified to follow
the spec as outlined in the CHANGES noted for 11/27/07 below.
Fixed Issue 97. Failure with code validation when the original
source files aren't present. Validation step now ignores
the missing file.
Minor fixes to version numbers.

| 1 | PLY is a 100% Python implementation of the common parsing tools lex and yacc. | 1 | PLY is yet another implementation of lex and yacc for Python. Some notable | |
| 2 | Here are a few highlights: | 2 | features include the fact that its implemented entirely in Python and it uses | |
| 3 | LALR(1) parsing which is efficient and well suited for larger grammars. | |||
| 4 | ||||
| 5 | PLY provides most of the standard lex/yacc features including support for empty | |||
| 6 | productions, precedence rules, error recovery, and support for ambiguous | |||
| 7 | grammars. | |||
| 3 | 8 | |||
| 4 | - PLY is very closely modeled after traditional lex/yacc. If you know how to | 9 | PLY is extremely easy to use and provides very extensive error checking. It is | |
| 5 | use these tools in C, you will find PLY to be similar. | 10 | compatible with both Python 2 and Python 3. | |
| 6 | ||||
| 7 | - PLY provides *very* extensive error reporting and diagnostic information to | |||
| 8 | assist in parser construction. The original implementation was developed | |||
| 9 | for instructional purposes. As a result, the system tries to identify the | |||
| 10 | most common types of errors made by novice users. | |||
| 11 | ||||
| 12 | - PLY provides full support for empty productions, error recovery, precedence | |||
| 13 | specifiers, and moderately ambiguous grammars. | |||
| 14 | ||||
| 15 | - Parsing is based on LR-parsing which is fast, memory efficient, better | |||
| 16 | suited to large grammars, and which has a number of nice properties when | |||
| 17 | dealing with syntax errors and other parsing problems. Currently, PLY builds | |||
| 18 | its parsing tables using the LALR(1) algorithm used in yacc. | |||
| 19 | ||||
| 20 | - PLY uses Python introspection features to build lexers and parsers. This | |||
| 21 | greatly simplifies the task of parser construction since it reduces the | |||
| 22 | number of files and eliminates the need to run a separate lex/yacc tool | |||
| 23 | before running your program. | |||
| 24 | ||||
| 25 | - PLY can be used to build parsers for "real" programming languages. Although | |||
| 26 | it is not ultra-fast due to its Python implementation, PLY can be used to | |||
| 27 | parse grammars consisting of several hundred rules (as might be found for a | |||
| 28 | language like C). The lexer and LR parser are also reasonably efficient | |||
| 29 | when parsing typically sized programs. People have used PLY to build | |||
| 30 | parsers for C, C++, ADA, and other real programming languages. |
