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

PY3COMPILE(1)                                                                                                                        PY3COMPILE(1)

NAME

       py3compile - byte compile Python 3 source files

SYNOPSIS

          py3compile [-V [X.Y][-][A.B]] DIR_OR_FILE [-X REGEXPR]

          pycompile -p PACKAGE

DESCRIPTION

       Wrapper around Python standard library's py_compile module to byte-compile Python 3 files.

OPTIONS

       --version
              show program's version number and exit

       -h, --help
              show this help message and exit

       -f, --force
              force rebuild of byte-code files even if timestamps are up-to-date

       -O     byte-compile to .pyo files

       -q, --quiet
              be quiet

       -v, --verbose
              turn verbose mode on

       -p PACKAGE, --package=PACKAGE
              specify Debian package name whose files should be bytecompiled

       -V VRANGE
              force  private  modules to be bytecompiled with Python 3 version from given range, regardless of the default Python 3 version in the
              system. If there are no other options, bytecompile all public modules for installed Python 3 versions that match given range.   VER-
              SION_RANGE examples:

                 o 3.1    version 3.1 only,

                 o 3.1-   version 3.1 or newer,

                 o 3.1-3.3        version 3.1 or 3.2,

                 o -4.0   all supported 3.X versions

       -X REGEXPR, --exclude=REGEXPR
              exclude items that match given REGEXPR. You may use this option multiple times to build up a list of things to exclude
