Log Message:
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.

-PLY is a 100% Python implementation of the common parsing tools lex and yacc.
-Here are a few highlights:
+PLY is yet another implementation of lex and yacc for Python. Some notable
+features include the fact that its implemented entirely in Python and it uses
+LALR(1) parsing which is efficient and well suited for larger grammars.
+
+PLY provides most of the standard lex/yacc features including support for empty
+productions, precedence rules, error recovery, and support for ambiguous
+grammars.
 
- -  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.
+PLY is extremely easy to use and provides very extensive error checking. It is
+compatible with both Python 2 and Python 3.
