A one-week hack to scratch my own itch for controlling StreamDecks on Linux, from a single configuration file streamdack.cfg, with no GUI, no doc, and no support.
I had previously been using the excellent https://timothycrosley.github.io/streamdeck-ui , with my only complaint being an inability to trigger actions on StreamDeck key releases. Dealing with that complaint got a little out of hand and turned into this.
The StreamDack configuration file format is "TOML-ish" meaning it's TOML but unquoted strings that look like variable names are interpreted as strings. (Hmm I'll need to commit the tomlikey repo that supplies that too.)
StreamDack incorporates the great https://pypi.org/project/streamdeck/ library (on github at https://github.com/abcminiuser/python-elgato-streamdeck) to do all the H/W access. python-elgato-streamdeck is licensed under the MIT License.
StreamDack's design approach is to make a screen abstraction to represent all your StreamDecks, placed into a single 2D space like monitors in a multi-monitor setup. But instead of being a screen of pixels it is a screen of StreamDeck keys. A hierarchical panel window manager redraws that screen, ultimately associating each key with a configurable Button, which can trigger Action sequences on key press or release or both. Action types include shell commands and changing visibility of Panels.
