Gitlab CI Launchpad Mini Controller

And it's in Rust 🦀!

Aim

I wanted to use my Launchpad Mini in a way that was original and useful to me, as I don't produce music. The Launchpad is a glorified MIDI pad with some LEDs, and as a MIDI device, it can be interfaced with to do pretty much anything with it.

I used mainly two libraries for this project:

• gitlab to interact with the Gitlab API
• launchy to interact with the Launchpad

These two libraries are maintained at the moment this README is being written.

Building

As any other cargo project, it can be built with a simple command:

cargo build --release

Logging

This project uses the env_logger crate for logging. You can take a look at its documentation to see how to adjust the log level instead of using the default error log level.

Configuring

The configuration is done through a JSON file, named config.json and located in the current working directory. An example configuration file is provided, config.json.example.

The abs_x and abs_y coordinate are defined using the top-left grid tile as the origin.

Clicking on a tile opens the corresponding web page for the project linked to this tile. Clicking on the A button will light it up, it is the restart button. If you click on a tile with the A button lit up, it will retry or create a new pipeline for this project and for this ref. You can disengage the restart mode by pressing again the A button.

Limitations

This project has some limitations right now, and some of them will be fixed:

• the program is able to talk to one and only one gitlab API right now
• the configuration file has to be in the current working directory
• only one page is allowed, but 8 could be leveraged later using the 8 selectors
• the refresh delay is fixed for all threads and is at 2 seconds
• the launchpad mini is the only launchpad that can be used with this project
