Requirements
------------

* PyCairo
* PyGObject ≥ 3.36
* Python ≥ 3.7
* YOGA ≥ 1.1.0


Installation
------------

Arch Linux
~~~~~~~~~~

The package is available on AUR (``yoga-image-optimizer``):

* https://aur.archlinux.org/packages/yoga-image-optimizer


Flatpak (Linux)
~~~~~~~~~~~~~~~

A Flatpak package is available on Flathub. This is currently the simplest way to install YOGA Image Optimizer on all major Linux distributions:

* https://flathub.org/apps/details/org.flozz.yoga-image-optimizer


Linux (PyPI)
~~~~~~~~~~~~

You must install the dependencies on your system first. It can be done via the following command on Debian and Ubuntu::

    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 with pip::

    sudo pip3 install yoga-image-optimizer

**NOTE:** Installing from PyPI will not install ``.desktop`` file and manual page; you will not be able to run the software from your graphical app menu (GNOME Shell etc.).


Linux (source)
~~~~~~~~~~~~~~

You must install the dependencies on your system first. It can be done via the following command on Debian and Ubuntu::

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

Then clone this repository and navigate to it::

    git clone https://github.com/flozz/yoga-image-optimizer.git
    cd yoga-image-optimizer

Then install YOGA Image Optimizer using pip::

    sudo pip3 install .

Finally, you can install the ``.desktop`` file, icons and manual page using the following command::

    sudo ./linuxpkg/copy-data.sh /usr


Windows
~~~~~~~

Download either the portable .zip version or the Windows installer from the releases page:

* https://github.com/flozz/yoga-image-optimizer/releases


Usage
-----

Just type the following command to run YOGA Image Optimizer::

    yoga-image-optimizer

You can also give some image files to open::

    yoga-image-optimizer  image1.png  image2.jpeg


**NOTE:** If you installed YOGA Image Optimizer from Flathub, you will have to run the following command instead::

    flatpak run org.flozz.yoga-image-optimizer  image1.png  image2.jpeg

Questions
~~~~~~~~~

If you have any question, you can:

* `Open an issue <https://github.com/flozz/yoga-image-optimizer/issues>`_ on GitHub
* `Ask on Discord <https://discord.gg/P77sWhuSs4>`_ (I am not always available to chat, but I try to answer to everyone)


Bugs
~~~~

Please `open an issue <https://github.com/flozz/yoga-image-optimizer/issues>`_ on GitHub with as much information as possible if you found a bug:

* Your operating system / Linux distribution (and its version)
* How you installed the software
* All the logs and message outputted by the software
* etc.


Pull requests
~~~~~~~~~~~~~

Please consider `filing a bug <https://github.com/flozz/yoga-image-optimizer/issues>`_ before starting to work on a new feature; it will allow us to discuss the best way to do it. It is obviously unnecessary if you just want to fix a typo or small errors in the code.

Please note that your code must follow the coding style defined by the `pep8 <https://pep8.org>`_ and pass tests. `Black <https://black.readthedocs.io/en/stable>`_ and `Flake8 <https://flake8.pycqa.org/en/latest>`_ are used on this project to enforce the coding style.


Translate YOGA Image Optimizer
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

You can help translating it if the software is not available on your language.

To translate YOGA Image Optimizer, you can:

* Submit your translations creating a pull request on GitHub
* Translate online via `POEditor <https://poeditor.com/join/project/RoQ2r9rv89>`_

If you submit your translations with a pull request on GitHub. Do not forget to add your name as the translation of the ``translator-credits`` key (one name per line, email is optional)::

    #: yoga_image_optimizer/about_dialog.py:38
    msgid "translator-credits"
    msgstr ""
    "John DOE\n"
    "Other TRANSLATOR <foobar@example.org>\n"


Run the tests
~~~~~~~~~~~~~

You must install `Nox <https://nox.thea.codes/>`__ first::

    pip3 install nox

Then you can check for lint error::

    nox --session lint

or run the tests::

    nox --session test

You can use following commands to run the tests only on a certain Python version (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
    nox --session test-3.10
    nox --session test-3.11

You can also fix coding style errors automatically with::

    nox -s black_fix


Build, extract or update build translations
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

You must install `Nox <https://nox.thea.codes>`__ first::

    pip3 install nox

To extract messages and update locales, run::

    nox --session locales_update

To compile locales, run::

    nox --session locales_compile

**NOTE:** you must have ``msgfmt``, ``msgmerge`` and ``xgettext`` executable installed on your system to run the above commands. It can be done via the following command on Debian and Ubuntu::

    sudo apt install gettext
