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](scripts) (via shorthand syntax) and [ironvars](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:
|
|
|
|
```toml
|
|
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:
|
|
|
|
```toml
|
|
show_if = "exit 0" # script
|
|
show_if = "#show_module" # variable
|
|
```
