Code

Are you familiar with coding in PHP or Python? Have you made projects in Liquidsoap and some of the other services we use? Take a look at the list of bugs and feature requests, and then fork our repo and have a go! Just use the Fork button at the top of our GitHub page, clone the forked repo to your desktop, open up a favorite editor and make some changes, and then commit, push, and open a pull request.

Knowledge on how to use Github and Git will suit you well, use the links for a quick 101.

LibreTime uses the black coding style for Python and you must ensure that your code follows it. If not, the CI will fail and your Pull Request will not be merged. Similarly, the Python import statements are sorted with isort. There is configuration provided for pre-commit, which will ensure that code matches the expected style and conventions when you commit changes. It is set up by running:

sudo apt install pre-commit
pre-commit install

You can also run it anytime using:

pre-commit run --all-files

Testing and CI/CD

Before submitting code to the project, it's a good idea to test it first. To do this, it's easiest to install LibreTime in a virtual machine on your local system or in a cloud VM. We have instructions for setting up a virtual instance of LibreTime with Vagrant and Multipass.

If you would like to try LibreTime in a Docker image, Odclive has instructions here for setting up a test image and a more persistent install.

Modifying the Database

LibreTime is designed to work with a PostgreSQL database server running locally. LibreTime uses PropelORM to interact with the ZendPHP components and create the database. The version 2 API uses Django to interact with the same database.

If you are a developer seeking to add new columns to the database here are the steps.

  1. Modify legacy/build/schema.xml with any changes.
  2. Run dev_tools/propel_generate.sh
  3. Update the upgrade.sql under legacy/application/controllers/upgrade_sql/VERSION for example ALTER TABLE imported_podcast ADD COLUMN album_override boolean default 'f' NOT NULL;
  4. Update the models under api/libretime_api/models/ to reflect the new changes.
