dune-release 1.3.1 · OCaml Package

Safe OS operations.

All the commands in that module can have side-effects. They also all take a --dry-run paramater which cause the side-effect to be discarded and to display a message instead. Some of these commands also have a `--force` option: this causes the message to be printed AND the side-effects to be caused.

type error = Bos_setup.R.msg

val run : 
  dry_run:bool ->
  ?force:bool ->
  ?sandbox:bool ->
  Bos.Cmd.t ->
  (unit, error) Stdlib.result

val run_quiet : 
  dry_run:bool ->
  ?force:bool ->
  ?sandbox:bool ->
  Bos.Cmd.t ->
  (unit, error) Stdlib.result

Same as run but redirects err and out to null

val run_io : 
  dry_run:bool ->
  ?force:bool ->
  ?sandbox:bool ->
  default:'a ->
  Bos.Cmd.t ->
  Bos.OS.Cmd.run_in ->
  (Bos.OS.Cmd.run_out -> ('a, 'b) Stdlib.result) ->
  ('a, 'b) Stdlib.result

val run_out : 
  dry_run:bool ->
  ?force:bool ->
  ?sandbox:bool ->
  ?err:Bos.OS.Cmd.run_err ->
  default:'a ->
  Bos.Cmd.t ->
  (Bos.OS.Cmd.run_out -> ('a, 'b) Stdlib.result) ->
  ('a, 'b) Stdlib.result

val run_status : 
  dry_run:bool ->
  ?force:bool ->
  ?sandbox:bool ->
  Bos.Cmd.t ->
  (Bos.OS.Cmd.status, error) Stdlib.result

val delete_dir : 
  dry_run:bool ->
  ?force:bool ->
  Fpath.t ->
  (unit, error) Stdlib.result

val delete_path : dry_run:bool -> Fpath.t -> (unit, error) Stdlib.result

val read_file : dry_run:bool -> Fpath.t -> (string, error) Stdlib.result

val write_file : 
  dry_run:bool ->
  ?force:bool ->
  Fpath.t ->
  string ->
  (unit, error) Stdlib.result

val with_dir : 
  dry_run:bool ->
  Fpath.t ->
  ('a -> 'b) ->
  'a ->
  ('b, error) Stdlib.result

val file_exists : dry_run:bool -> Fpath.t -> (bool, error) Stdlib.result

val dir_exists : dry_run:bool -> Fpath.t -> (bool, error) Stdlib.result

val file_must_exist : dry_run:bool -> Fpath.t -> (Fpath.t, error) Stdlib.result

val out : 'a -> 'a * Bos.OS.Cmd.run_status

val mkdir : dry_run:bool -> Fpath.t -> (bool, error) Stdlib.result

val cp : 
  dry_run:bool ->
  rec_:bool ->
  force:bool ->
  src:Fpath.t ->
  dst:Fpath.t ->
  (unit, error) Stdlib.result

cp ~dry_run ~rec ~force ~src ~dst copies src to dst. If rec is true, copies directories recursively. If force is true, overwrite existing files. The usual force arguments from other functions in this module is renamed force_side_effects here.

val relativize : src:Fpath.t -> dst:Fpath.t -> (Fpath.t, error) Stdlib.result

relativize ~src ~dst return a relative path from src to dst. If such a path can't be expressed, i.e. srs and dst don't have a common root, returns an error.
