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
