Usage:
%s [OPTIONS]... [ FILE | DIR]...
%s [--help | -h | --V | --version]
Examples:
%s foo.pyc bar.pyc # decompile foo.pyc, bar.pyc to stdout
%s -o . foo.pyc bar.pyc # decompile to ./foo.pyc_dis and ./bar.pyc_dis
%s -o /tmp /usr/lib/python1.5 # decompile whole library
Options:
-o <path> output decompiled files to this path:
if multiple input files are decompiled, the common prefix
is stripped from these names and the remainder appended to
<path>
uncompyle6 -o /tmp bla/fasel.pyc bla/foo.pyc
-> /tmp/fasel.pyc_dis, /tmp/foo.pyc_dis
uncompyle6 -o /tmp bla/fasel.pyc bar/foo.pyc
-> /tmp/bla/fasel.pyc_dis, /tmp/bar/foo.pyc_dis
uncompyle6 -o /tmp /usr/lib/python1.5
-> /tmp/smtplib.pyc_dis ... /tmp/lib-tk/FixTk.pyc_dis
-c <file> attempts a disassembly after compiling <file>
-d print timestamps
-p <integer> use <integer> number of processes
-r recurse directories looking for .pyc and .pyo files
--verify compare generated source with input byte-code
(requires -o)
--help show this message
Debugging Options:
--asm -a include byte-code (disables --verify)
--grammar -g show matching grammar
--tree -t include syntax tree (disables --verify)
Extensions of generated files:
'.pyc_dis' '.pyo_dis' successfully decompiled (and verified if --verify)
+ '_unverified' successfully decompile but --verify failed
+ '_failed' decompile failed (contact author for enhancement)
