ironbar/docs/Ironvars.md

Ironvars are runtime variables that can be referenced in several places in your config, then set using the IPC server (such as via the CLI) using the set command.

Keys can consist of alphanumeric characters, - and _ only. Any UTF-8 string is a valid value.

Reference values using #my_variable. These update as soon as the value changes.

You can set defaults using the ironvar_defaults key in your top-level config.
