Ren'Py development takes place on the master branch, and occasionally on feature branches.
Ren'Py depends on a number of Python modules written in Cython and C. For changes to Ren'Py that only involve Python modules, you can use the modules found in the latest nightly build. Otherwise, you'll have to compile the modules yourself.
The development scripts assume a POSIX-like platform. The scripts should run on Linux or macOS, and can be made to run on Windows using an environment like MSYS.
Nightly builds can be downloaded from:
Note that the latest nightly build is at the bottom of the list. Once you've unpacked the nightly, change into this repository, and run:
./after_checkout.sh <path-to-nightly>Once this script completes, you should be able to run Ren'Py using renpy.sh, renpy.app, or renpy.exe, as appropriate for your platform.
If the current nightly build doesn't work, please wait 24 hours for a new build to occur. If that build still doesn't work, contact Tom (pytom at bishoujo.us, or @renpytom on twitter) to find out what's wrong.
The doc symlink will dangle until documentation is built, as described below.
Building the modules requires you have the many dependencies installed on your system. On Ubuntu and Debian, these dependencies can be installed with the command:
sudo apt install virtualenvwrapper python3-dev libavcodec-dev libavformat-dev \
libswresample-dev libswscale-dev libharfbuzz-dev libfreetype6-dev libfribidi-dev libsdl2-dev \
libsdl2-image-dev libsdl2-gfx-dev libsdl2-mixer-dev libsdl2-ttf-dev libjpeg-devRen'Py requires SDL_image 2.6 or greater. If your distribution doesn't include that version, you'll need to download it from:
We strongly suggest installing the Ren'Py modules into a Python virtualenv. To create a new virtualenv, open a new terminal and run:
. /usr/share/virtualenvwrapper/virtualenvwrapper.sh
mkvirtualenv renpyTo return to this virtualenv later, run:
. /usr/share/virtualenvwrapper/virtualenvwrapper.sh
workon renpyAfter activating the virtualenv, install additional dependencies:
pip install -U cython future six typing pefile requests ecdsaThen, install pygame_sdl2 by running the following commands:
git clone https://www.github.com/renpy/pygame_sdl2
pushd pygame_sdl2
python setup.py install
python setup.py install_headers
popdNext, set RENPY_DEPS_INSTALL To a :-separated (;-separated on Windows) list of paths containing the dependencies, and RENPY_CYTHON to the name of the cython command:
export RENPY_DEPS_INSTALL="/usr:/usr/lib/$(gcc -dumpmachine)/"
export RENPY_CYTHON=cythonFinally, use setup.py in the Ren'Py module directory to compile and install the modules that support Ren'Py:
pushd module
python setup.py install
popdRen'Py will be installed into the activated virtualenv. It can then be run using the command:
python renpy.pyBuilding the documentation requires Ren'Py to work. You'll either need to link in a nightly build, or compile the modules as described above. You'll also need the Sphinx documentation generator. If you have pip working, install Sphinx using:
pip install -U sphinx sphinx_rtd_theme sphinx_rtd_dark_modeOnce Sphinx is installed, change into the sphinx directory inside the Ren'Py checkout and run:
./build.shRen'Py's documentation consists of reStructuredText files found in sphinx/source, and generated documentation found in function docstrings scattered throughout the code. Do not edit the files in sphinx/source/inc directly, as they will be overwritten.
Docstrings may include tags on the first few lines:
- :doc: section kind
Indicates that this function should be documented. section gives the name of the include file the function will be documented in, while kind indicates the kind of object to be documented (one of
function,methodorclass. If omitted, kind will be auto-detected.- :name: name
The name of the function to be documented. Function names are usually detected, so this is only necessary when a function has multiple aliases.
- :args: args
This overrides the detected argument list. It can be used if some arguments to the function are deprecated.
For example:
def warp_speed(factor, transwarp=False):
"""
:doc: warp
:name: renpy.warp_speed
:args: (factor)
Exceeds the speed of light.
"""
renpy.engine.warp_drive.engage(factor)For best practices when it comes to translating the launcher and template game, please read:
