Unrpyc is a script to decompile Ren'Py (http://www.renpy.org/) compiled .rpyc script files. It will not extract files from .rpa archives. For that, use rpatool or [UnRPA] (https://github.com/Lattyware/unrpa).
Thanks to recent changes, unrpyc no longer needs internal renpy structures to work.
--version show program's version number and exit -h, --help show this help message and exit -c, --clobber overwrites existing output files -d, --dump Instead of decompiling, pretty print the contents of the AST in a human readable format. This is mainly useful for debugging. -p, --processes use the specified number of processes to decompile --sl1-as-python Only dumping and for decompiling screen language 1 screens. Convert SL1 Python AST to Python code instead of dumping it or converting it to screenlang. --comparable Only for dumping, remove several false differences when comparing dumps. This suppresses attributes that are different even when the code is identical, such as file modification times. --no-pyexpr Only for dumping, disable special handling of PyExpr objects, instead printing them as strings. This is useful when comparing dumps from different versions of Ren'Py. It should only be used if necessary, since it will cause loss of information such as line numbers. --init-offset Attempt to guess when init offset statements were used and insert them. This is always safe to enable if the game's Ren'Py version supports init offset statements, and the generated code is exactly equivalent, only less cluttered.
Usage: [python2] unrpyc.py [options] script1 script2 ...
You can give several .rpyc files on the command line. Each script will be decompiled to a corresponding .rpy on the same directory. Additionally, you can pass directories. All .rpyc files in these directories or their subdirectories will be decompiled. By default, the program will not overwrite existing files, use -c to do that.
This script will try to disassemble all AST nodes. In the case it encounters an unknown node type, which may be caused by an update to Ren'Py somewhere in the future, a warning will be printed and a placeholder inserted in the script when it finds a node it doesn't know how to handle. If you encounter this, please open an issue to alert us of the problem.
For the script to run correctly it is required for the unrpyc.py file to be in the same directory as the modules directory.
You can also import the module from python and call unrpyc.decompile_rpyc(filename, ...) directly
As of renpy version 6.18 the way renpy handles screen language changed significantly. Due to this significant changes had to be made, and the script might be less stable for older renpy versions. If you encounter any problems due to this, please report them.
Alternatively there is an experimental version of the decompiler packed into one file available at https://github.com/CensoredUsername/unrpyc/releases This version will decompile a game from inside the renpy runtime. Simply copy the un.rpyc file into the "game" directory inside the game files and everything will be decompiled.
- renpy version 6
- Windows, OSX and Linux
Unrpyc has only been tested on versions up to 6.99.9, though newer versions are expected to mostly work. If you find an error due to a new ren'py version being incompatible, please open an issue.
- Python version 2.7
