val find : ?win_exe:bool -> ?search:B0_std.Fpath.t list -> unit -> (B0_std.Cmd.t option, string) Stdlib.result

find ?win_exe ?search () finds a suitable editor. This is (in order):

  1. Ok (Some pager) if pager is a tool invocation parsed from the VISUAL environment variable that can be found via Os.Cmd.find ?search.
  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

edit-files editor fs uses editor to edit the files fs. If editor is:

  • 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.
