Limitations

As this is an early development version:

  • PNG Optimization is very, very, VERY slow due to unbalanced ZoppfliPNG optimization options set by YOGA, this will be improved in the future.

Requirements

  • Python >= 3.7,

  • YOGA >= 0.11.0,

  • PyCairo,

  • PyGObject >= 3. 36,

First, you will need to install some dependencies on your system. On Debian and Ubuntu this can be achieved with the following command:

sudo apt install git build-essential python3 python3-dev python3-pip libgirepository1.0-dev libcairo2-dev pkg-config gir1.2-gtk-3.0

Then install YOGA Image Optimizer using pip:

Bugs

If you found a bug, please open an issue on Github with as much information as possible:

  • What is your operating system / Linux distribution (and its version),

  • How you installed the software,

  • All the logs and message outputted by the software,

Pull Requests

Please consider filing a bug before starting to work on a new feature. This will allow us to discuss the best way to do it. This is of course not necessary if you just want to fix some typo or small errors in the code.

Please note that your code must pass tests and follow the coding style defined by the pep8. Flake8 and Black are used on this project to enforce coding style.

Running The Tests

You will first have to install nox:

pip3 install nox

Then you can check for lint error:

nox --session lint

or run the tests:

nox --session test

To run the tests only for a specific Python version, you can use following commands (the corresponding Python interpreter must be installed on your machine):

nox --session test-3.7
nox --session test-3.8
nox --session test-3.9

You can also fix automatically coding style errors with:

nox -s black_fix

Extract, Update or Build Translations

You will first have to install nox:

pip3 install nox

To extract messages and update locales run:

nox --session locales_update

To compile locales, run:

nox --session locales_compile

NOTE: you will need to have xgettext, msgmerge and msgfmt executable installed on your system to run the above commands. On Debian / Ubuntu, they can be installed with the following command:

sudo apt install gettext
