How to Typst + PanDiff

1. Prepare a diff.typ source file as shown in this Gist.
2. Provided you have two Typst SOURCE files named a.typ and b.typ, execute:

   pandiff --from typst --to typst a.typ b.typ > diff.content.typ

3. Compile the diff.typ file:

   typst compile diff.typ

diff.typ

#let diff-box(color, contents) = box(
  outset: 0.25em,
  fill: color.transparentize(85%),
  text(fill: color, contents),
)

#let INSERT_RE = regex(`\{\+{2}(.+?)\+{2}\}`.text)
#show INSERT_RE: this => {
  let (contents,) = this.text.match(INSERT_RE).captures
  diff-box(green, underline(contents))
}

#let DELETE_RE = regex(`\{(?:-{2}|–)(.+?)(?:-{2}|–)\}`.text)
#show DELETE_RE: this => {
  let (contents,) = this.text.match(DELETE_RE).captures
  diff-box(red, strike(contents))
}

#let REPLACE_RE = regex(`\{(?:~{2})(.+?)~>(.+?)(?:~{2})\}`.text)
#show REPLACE_RE: this => {
  let (old, new) = this.text.match(REPLACE_RE).captures
  diff-box(orange)[
    #strike(old)
    #underline(new)
  ]
}
