$fill

Fills a counted phrase with its own slots: a value of the form { phrase, slots } becomes the phrase with each {slot} replaced. A value of any other form passes through unchanged.

The source

{
  progress: { phrase: '{n} of {total}', slots: { n: 1, total: 12 } },
  plain: 'done',
}

The config

{
  filled: { $fill: { $ref: '$.progress' } },
  untouched: { $fill: { $ref: '$.plain' } },
}

What comes out

{ filled: '1 of 12', untouched: 'done' }
