Module Mt_self.Make_user_dir_opt

Builds a User_dir_opt from an existing User_dir. The first parameter is the parent directory. The second gives the name of the directory to create (also used to create the option name), a possible environment variable name and the help message for the option.

Parameters

module _ : Frama_c_kernel.Parameter_sig.User_dir
module _ : sig ... end

Signature

include Frama_c_kernel.Parameter_sig.User_dir
val get_dir : ?create_path:bool -> string -> Frama_c_kernel.Filepath.t

get_dir ~create_path name tries to get the directory name. The function aborts if:

  • a file named name exists,
  • creating a the directory fails.

Otherwise returns the path, and creates it if create_path is true (it defaults to false). Subdirectories modules can be created with Builder.Make_user_dir and Builder.Make_user_dir_opt.

val get_file : ?create_path:bool -> string -> Frama_c_kernel.Filepath.t

get_file ~create_path name tries to get the file name. The function aborts if:

  • a directory named name exists,
  • creating the path to the file fails.

Otherwise returns the path, and creates the directories that lead to the file if create_path is true (it defaults to false). The file is *not* created by the function.

val set : Frama_c_kernel.Filepath.t -> unit

Sets the <user-dir> directory (without creating it).

val get : unit -> Frama_c_kernel.Filepath.t
  • returns

    the <user-dir> directory (without creating it).

val is_set : unit -> bool
  • returns

    whether the <user-dir> has been set.
