Bindings for Pango for using with Manim.

Project description


PyPI Latest Release PyPI - Wheel PyPI - Downloads PyPI - License PyPI - Python Version Documentation Status

ManimPango is a C binding for Pango using Cython, which is internally used in Manim to render (non-LaTeX) text.


Installing ManimPango is super easy, just use pip. It is manimpango in PyPi.

pip install manimpango

For Linux Users, there are no Wheels. You must have a C compiler as well as Pango and its dependencies along with the Pango development headers. See BUILDING for more information.


To make it easier for developers to contribute, we have a pre-commit workflow that will check for black formatting and flake checking.

pip install pre-commit
pre-commit install



For building ManimPango, you need

  • a C compiler
  • Python's development headers
  • pkg-config
  • Pango along with its development headers and its dependencies.

If you are on MacOS, you can use brew to install those. Using MacPorts is also possible, but their version of Pango is old and will probably not be updated in the near future.

brew install pango pkg-config

If you are on Linux, you can use a system package manager to do so. For example, if you are on Debian based system, you can use apt

apt install libpango1.0-dev pkg-config python3-dev

Arch Linux: pacman -S pango pkgconf

Fedora: dnf install pango-devel pkg-config python3-devel

Or similar in your system's package manager.

Using tar archives

If you don't want to contribute to this repository, you can use the tar archives published in PyPi, or just use pip to install using

pip install manimpango --no-binary :all:

Note: pip by default uses wheels, so make sure to pass the --no-binary parameter.

Using git clones / Contributing

Please remember to do this inside your virtual environment, if you want to use your Manimpango with Manim.

python -m venv ./venv
source venv/bin/activate # Linux/macOS
venv\Scripts\activate # Windows

If you are using a clone of this repository, you will need Cython which can be easily installed using pip:

pip install Cython

After that you can use pip to install the clone with the following command:

pip install -e .
pip install -r requirements-dev.txt .

Next, run the setup script:

python build_ext -i

After installation is complete, you should be able to run pytest:


You will need to this way if you want to contribute to ManimPango.

Contributing with Windows

If you are a normal user, don't read this, you have wheels which you can just install directly using pip.

If you want to contribute to ManimPango and you are on Windows, this section is for you.

As Windows does not include a C compiler by default, you will first need to install one. You have two choices:

  1. MinGW/Msys2

  2. Visual Studio


  1. Download MSYS2 from the download link provided on their page and install it according to their instructions.
  2. Once you have MSYS2 installed, it offers you three different shells: the MinGW32 shell, the MinGW64 shell and MSYS shell. In order for the following steps to work, you have to open the MSYS2 MinGW64 shell (you can search for this). Small hint: it has a blue color logo.
  3. Run the following commands to install Python, Pango, Cython, Numpy, Scipy, Pillow, Pycairo and ffmpeg
pacman -S mingw-w64-x86_64-python
pacman -S mingw-w64-x86_64-python-pip
pacman -S mingw-w64-x86_64-pango
pacman -S mingw-w64-x86_64-cython
pacman -S mingw-w64-x86_64-python-numpy
pacman -S mingw-w64-x86_64-python-scipy
pacman -S mingw-w64-x86_64-python-pillow
pacman -S mingw-w64-x86_64-python-cairo
pacman -S mingw-w64-x86_64-ffmpeg
  1. Still in the same shell, install Manim using pip install manim.
  2. Finally, get your clone of ManimPango, cd into that directory and then run pip install -e .. Note You can't use it with your regular Python version. It will cause weird errors if you do so. For working with ManimPango, you must be inside the MSYS2 MINGW64 shell.
  3. You can then use manim inside that shell, to run Manim. Hint: If you want to try out Python interactively, you can open idle using the command python -m idlelib inside that shell.

Visual Studio

First, install Visual Studio as specified in Possibly Visual Studio Build Tools 2019 with Windows10 SDK.

Then run the script at packing/ This will get a Pango build along with pkg-config and install it at C:\cibw\vendor. Add C:\cibw\vendor\bin and C:\cibw\vendor\pkg-config\bin to PATH.

Note: You can change the install location by editing line 24 of the file packing/

Then set an environment variable PKG_CONFIG_PATH=C:\cibw\vendor\lib\pkgconfig.

Then you can install Cython using

pip install Cython

Finally, you can install your local ManimPango clone just like any other python package by typing:

pip install .

Important: You have to to use before running ManimPango. Alternatively, you need to copy the dll at C:\cibw\vendor\bin to the folder where ManimPango is compiled. This is applicable for Python 3.8 and above.
