val current_dir_name : string
|
|
(* The conventional name for the current directory
|
|
(e.g. [.] in Unix). *)

val concat : string -> string -> string
|
|
(* [concat dir file] returns a file name that designates file
|

[file] in directory [dir]. *)
|
|
val is_relative : string -> bool
|
|
(* Return [true] if the file name is relative to the current
|
|
directory, [false] if it is absolute (i.e. in Unix, starts
|
|
with [/]. *)
|
|
val is_implicit : string -> bool
|
|
(* Return [true] if the file name is relative and does not start
|
|
with an explicit reference to the current directory ([./] or
|
|
[../] in Unix), [false] if it starts with an explicit reference
|
|
to the root directory or the current directory. *)

val check_suffix : string -> suff:string -> bool

|
(* [check_suffix name suff] returns [true] if the filename [name]

ends with the suffix [suff]. *)

val chop_suffix : string -> suff:string -> string

(* [chop_suffix name suff] removes the suffix [suff] from

the filename [name]. The behavior is undefined if [name] does not

end with the suffix [suff]. *)

(* Return the given file name without its extension. The extension
|
|
is the shortest suffix starting with a period, [.xyz] for instance.

Raise [Invalid_argument] if the given name does not contain

a period. *)

val basename : string -> string
|

val dirname : string -> string
|

(* Split a file name into directory name / base file name.
|
|
[concat (dirname name) (basename name)] returns a file name
|
|
which is equivalent to [name]. Moreover, after setting the
|
|
current directory to [dirname name] (with [Sys.chdir]),
|
|
references to [basename name] (which is a relative file name)
|
|
designate the same file as [name] before the call to [Sys.chdir]. *)
|
|
val temp_file: prefix:string -> suffix:string -> string
|
|
(* [temp_file prefix suffix] returns the name of a
|
|
non-existent temporary file in the temporary directory.
|
|
The base name of the temporary file is formed by concatenating
|
|
[prefix], then a suitably chosen integer number, then [suffix].
|
|
Under Unix, the temporary directory is [/tmp] by default; if set,
|
|
the value of the environment variable [TMPDIR] is used instead.
|
|
Under Windows, the name of the temporary directory is the
|
|
value of the environment variable [TEMP],
|
|
or [C:\temp] by default.
|
|
Under MacOS, the name of the temporary directory is given
|
|
by the environment variable [TempFolder]; if not set,
|
|
temporary files are created in the current directory. *)
|
|
val quote: string -> string;;
|
|
(* Return a quoted version of a file name, suitable for use as
|
|
one argument in a shell command line, escaping any shell
|
|
meta-characters. *)
