Bind pipe-to-shell commands to keys?

[losnappas]

I often want to format text to a length, so I do |#fmt -73, and other times I want to stringify JSON, so I do JSON.stringify($), etc.

Is it possible I bind these commands to keys directly? Essentially like

"key": "ctrl+alt+w",
"command": "dance.selections.pipe.replace",
"args: { "input": "#fmt -73" }

What you did was supposed to work, but did not work as dance.selections.pipe.replace expands to commands([".selections.pipe"], [".edit.insert", { register: "|", ...argument }]), and therefore the input was only given to .edit.insert. To fix this, you can write

{
  "key": "ctrl+alt+w",
  "command": "dance.run",
  "args": {
    "commands": [
      [".selections.pipe", { "input": "#fmt -73" }],
      [".edit.insert", { "register": "|" }],
    ]
  }
}

For that particular case, though, 57fc476 changes the way composite commands work so that the input is passed to the first command, in this case, selections.pipe, so your example will work with no changes.
