## Python contributions

Python code is formatted using [black](https://github.com/psf/black) with the settings `-l 120`.
This is not enforced, and contributions with incorrect formatting will be accepted, but formatting this way is appreciated.

## Translations

### Contributing to an existing translation

* Go [here](https://github.com/sanderland/katrain/blob/master/katrain/i18n/locales/) and locate the `.po` file for your language. 
  * Alternatively, find the same file in the branch for the next version. 
* Correct the relevant `msgstr` entries.

### Adding a translation

Adding a translation requires making a new `.po` file with entries for that languages.

* Copy the [English .po file](https://github.com/sanderland/katrain/blob/master/katrain/i18n/locales/en/LC_MESSAGES/katrain.po)
* Change all the `msgstr` entries to your target language.
    * Note that anything between `{}` should be left as-is.
    * The information at the top of the file should also not be translated.

You can send me the resulting `.po` file, and I will integrate it into the program.
