sysm (system music) lets you configure specific sounds to be played on any arbitrary internal system event or an external event. This can give you visibility into your system while you are working (such as CPU/RAM/disk/network usage, audit events, etc.) without taking up space in your screen or notifications about external events such as something changing in some arbitrary website.
Rules require you to specify one "source" and one "type".
"source" is basically the information source, where the data will be fetched from, such as "shell_source" (runs an arbitrary shell command and returns the output), "file_column" (fetches specified column from a file), etc.
"type" controls how and when the audio will be played, for example "on_threshold_cross" (when value crosses given threshold), "on_match_when_past_no_match" (when value matches given regex pattern when it didn't match it last tick), "while_delta_above_threshold" (while delta between last tick's value and current value is above given threshold), etc.
New types and sources can be added by subclassing Source and Type. Contributions are welcome!
