LEPL 2.0 (Default branch)
LEPL is a recursive descent parser library writtenin Python. It is based on parser combinatorlibraries popular in functional programming, butalso exploits Python language features. Operatorsprovide a friendly syntax, and the consistent useof generators supports full backtracking andresource management. Backtracking implies that awide variety of grammars are supported, but onlyLL(k) are guaranteed to terminate.License: GNU Lesser General Public License (LGPL)Changes:
This release introduces several new features while keeping the same basic syntax for grammars (expressed as Python code). These include: evaluation via trampolining, which avoids any limits on recursion due to the small Python stack; memoisation, allowing both packrat parsing (Norvig 1991) and left-recursive grammars (Frost and Hafiz 2006); matcher graph rewriting, allowing manipulation of the grammar before parsing starts.Image

SHEDSKIN(1)															       SHEDSKIN(1)

NAME

       Shedskin - An experimental (restricted) Python-to-C++ Compiler

SYNOPSIS

       shedskin [OPTION]... FILE

DESCRIPTION

       Shed  Skin  is  an experimental compiler, that can translate pure, but implicitly statically typed Python (2.4-2.6) programs into optimized
       C++. It can generate stand-alone programs or extension modules that can be imported and used in larger Python programs.

       Besides the typing restriction, programs cannot freely use the Python standard library (although about 25 common modules,  such	as  random
       and re, are currently supported). Also, not all Python features, such as nested functions and variable numbers of arguments, are supported.

OPTIONS

	  -a --ann		 Output annotated source code (.ss.py)

	  -b --nobounds 	 Disable bounds checking

	  -e --extmod		 Generate extension module

	  -f --flags		 Provide alternate Makefile flags

	  -l --long		 Use long long integers

	  -m --makefile 	 Specify alternate Makefile name

	  -n --silent		 Silent mode, only show warnings

	  -o --noassert 	 Disable assert statements

	  -r --random		 Use fast random number generator (rand())

	  -s --strhash		 Use fast string hashing algorithm (murmur)

	  -w --nowrap		 Disable wrap-around checking

	  -x --traceback	 Print traceback for uncaught exceptions

	  -L --lib		 Add a library directory
