Dynamic values

In some configuration locations, Ironbar supports dynamic values, meaning you can inject content into the bar from an external source.

Currently two dynamic content sources are supported - scripts (via shorthand syntax) and ironvars.

Dynamic String

Dynamic strings can contain any mixture of static string elements, scripts and variables.

Scripts should be placed inside {{double braces}}. Both polling and watching scripts are supported.

Variables use the standard #name syntax. Variables cannot be placed inside scripts.

To use a literal hash, use ##. This is only necessary outside of scripts.

Example:

label = "{{cat greeting.txt}}, #subject"

Dynamic Boolean

Dynamic booleans can use a single source of either a script or variable to control a true/false value.

For scripts, you can just write these directly with no notation. Only polling scripts are supported. The script exit code is used, where 0 is true and any other code is false.

For variables, use the standard #name notation. An empty string, 0 and false are treated as false. Any other value is true.

Example:

show_if = "exit 0" # script
show_if = "#show_module" # variable
