  2. Ok (Some pager) if pager is a tool invocation parsed from the EDITOR environment variable that can be found via Os.Cmd.find ?win_exe ?search.
  3. Ok (Some pager) if nano can be found via Os.Cmd.find ?win_exe ?search.
  4. Ok None otherwise.
val edit_files : B0_std.Cmd.t option -> B0_std.Fpath.t list -> (B0_std.Os.Cmd.status, string) Stdlib.result

  • None, an error message is returned mentioning that no editor was found.
  • Some editor invokes the command with files fs and returns the exit status of the program.
