def to-group-name [] {
  str replace -ra "[()'\":,;|]" "" |
  str replace -ra '[\.\-\s]' "_"
}

# Get the jj log as a table
export def main [
  --revset (-r): string
  ...columns: string
] {
  let columns = if ($columns | is-empty) {
      [change_id description "author.name()" "author.timestamp()"]
    } else {
      $columns
    }
  let parser = $columns | each { $"{($in | to-group-name)}" } | str join (char fs)

  ( jj log ...(if $revset != null {[-r $revset]} else {[]})
       --no-graph
       -T $"($columns | str join $"++'(char fs)'++") ++ '(char rs)'"
