Package: minipy-ppf
a Python 2 minifier
by Gareth Rees <http://garethrees.org/>Thishttps://github.com/cpbotha/minipyis a fork of the originalhttps://github.com/gareth-rees/minipyonly to fix the broken PiPI
install, seehttps://github.com/gareth-rees/minipy/issues/52Introductionminipyis a minifier for Python 2. It rewrites Python 2 source code in a
way that preserves the meaning of the code while reducing it in
size. For example:$ cat fib.py
cache = {0: 0, 1: 1, 2: 1, 3: 2}
def fibonacci(n):
    """Return the nth Fibonacci number."""
    if n not in cache:
        a = n // 2
        r = n % 2
        m = (r * 2) - 1
        cache[n] = fibonacci(a + 1) ** 2 + m * fibonacci(a + r - 1) ** 2
    return cache[n]

$ minipy --rename --docstrings fib.py
b={0:0,1:1,2:1,3:2}
def c(a):
 if a not in b:d=a//2;e=a%2;f=e*2-1;b[a]=c(d+1)**2+f*c(d+e-1)**2
 return b[a]Command lineUsage: minipy [options] [-o OUTPUT] FILE

Options:
  --version             show program's version number and exit
  -h, --help            show this help message and exit
  -o OUTPUT, --output=OUTPUT
                        output file (default: stdout)
  -D, --docstrings      remove docstrings and other statements with no side
                        effects (implies --noselftest)
  -R, --rename          aggressively rename non-preserved variables
  -i INDENT, --indent=INDENT
                        number of spaces per indentation level
  -p PRESERVE, --preserve=PRESERVE
                        preserve words from renaming (separate by commas)
  --nojoinlines         put each statement on its own line
  --noselftest          skip the self-test
  --debug               dump the parse treeThe self-testGenerating minified source code without accidentally changing the
meaning is tricky: see thelist of issuesfor many awkward cases
that had to be fixed. Therefore, in its default operating mode, minipy
performs a “self-test”: it takes the minified code, re-parses it, and
asserts that the parse tree for the minified code is identical to the
parse tree for the original code. If the self-test passes, then you can
be highly confident that minipy has not changed the meaning of your
code.In order to pass the self-test, minipy must eschew a few changes to the
code that result in harmless changes to the parse tree. These changes
are:Replacingpasswith0.Replacing-(1)with-1.You can use the--noselftestoption to enable these changes, but by
disabling the self-test you accept a small risk of a bug in minipy
changing the meaning of your code.The optional transformations--renameand--docstringscan’t be
combined with the self-test, so these options imply--noselftest.Pleasereportall self-test failures, attaching the code that causes
the failure.RenamingPython’s use of introspection and duck typing means that it is not
possible to change names in a program without risk of changing the
meaning. The--renameoption to minipy therefore makes a “best attempt”
to discover names that need to be preserved, but does not guarantee
anything. Use at your own risk!The following names are preserved when renaming:Names specified on the command-line via the--preserveoption
(write--preserve=name1,name2,name3to preserve more than one name).Built-in names (abs,all,any,apply, …).Any name used as an attribute (.join,.index,.copy,.sort, …).Any name starting and ending with two underscores.Any name exported by a module in afrom module import *statement.Any name in the list assigned to the__all__global variable.Licenseminipy is free software: you can redistribute it and/or modify it under
