Original GitHub issue: https://github.com/JakeStanger/ironbar/issues/537

I have two monitors and I want to show two bars (top and bottom) in each monitor. Contents of bars in the same position but different monitor should be the same(e.g. top bar in monitor-1 and top bar in monitor-2).

I know there is a way to configure it, as below:

{
  "monitors": {
    "monitor-1": [
      { "position": "top", ... },
      { "position": "bottom", ... }
    ],
    "monitor-2": [
      { "position": "top", ... },
      { "position": "bottom", ... }
    ]
  }
}

but this is not very graceful, since I need to repeat the same object multiple times.

I want to know whether there is a way to set a "default" bars config for every monitors which supports multiple bars. Current way seems only support one bar as default.

Hey, there is no way to do this with JSON or TOML. YAML possibly has some templating features built in, although I've never tested if the Rust implementation includes them.

This can however be easily done with the Corn format and its inputs mechanism:

let {
  $bar = { start = [] center = [] end = [] }

  $bars = [
    { position = "top" ..$bar } 
    { position = "bottom" ..$bar } 
  ]
} in {
  monitors.monitor-1 = $bars
  monitors.monitor-2 = $bars
}
