How can I specify an exit code with Purescript

If I run the following using pulp run the process ends with status 0.

main :: forall e. Eff (console :: CONSOLE | e) Int
main = do
  log "Hello sailor!"
  pure 137

How can I exit the program with an error without throwing an exception?

If you're running on Node (which is what pulp run does), you should use Node facilities for this. Specifically, the function you want is Node.Process.exit:

import Node.Process(exit)

main = do
    log "Hello sailor!"
    exit 137
