Booktabs

If you like wrapping your algorithm in elegant horizontal lines, you can do so by setting the booktabs option to true.

#pseudocode-list(booktabs: true)[
  + do something
  + do something else
  + *while* still something to do
    + do even more
    + *if* not done yet *then*
      + wait a bit
      + resume working
    + *else*
      + go home
    + *end*
  + *end*
]

Together with the title option, you can produce

#pseudocode-list(booktabs: true, title: [My cool title])[
  + do something
  + do something else
  + *while* still something to do
    + do even more
    + *if* not done yet *then*
      + wait a bit
      + resume working
    + *else*
      + go home
    + *end*
  + *end*
]

Stroke

By default, the outer booktab strokes are text.fill + 2pt. You can change that with the option booktabs-stroke to any valid Typst stroke. The inner line will always have the same stroke as the outer ones, just with half the thickness.

Inset

By setting the title-inset option, you can specify the space around the title:

#pseudocode-list(booktabs: true, title: [My cool title], title-inset: 2em)[
  + do something
  + do something else
  + *while* still something to do
    + do even more
    + *if* not done yet *then*
      + wait a bit
      + resume working
    + *else*
      + go home
    + *end*
  + *end*
