Usage:
|
|
%s [OPTIONS]... FILE
|
|
%s [--help | -h | -V | --version]
|
|
|
|
Disassemble/Tokenize FILE with in the way that is done to
|
|
assist uncompyle6 in parsing the instruction stream. For example
|
|
instructions with variable-length arguments like CALL_FUNCTION and
|
|
BUILD_LIST have argument counts appended to the instruction name, and
|
|
COME_FROM psuedo instructions are inserted into the instruction stream.
|
|
Bit flag values encoded in an operand are expanding, EXTENDED_ARG
|
|
value are folded into the following instruction operand.
|
|
|
|
Like the parser, you may find this more high-level and or helpful.
|
|
However if you want a true disassembler see the Standard built-in
|
|
Python library module "dis", or pydisasm from the cross-version
|
|
Python bytecode package "xdis".
|
|
|
|
Examples:
|
|
%s foo.pyc
|
|
%s foo.py # same thing as above but find the file
|
|
%s foo.pyc bar.pyc # disassemble foo.pyc and bar.pyc
|
|
|
|
See also `pydisasm' from the `xdis' package.
|
|
|
|
Options:
|
|
-V | --version show version and stop
|
|
-h | --help show this message
