val current_dir_name : string

(** The conventional name for the current directory (e.g. [.] in Unix). *)

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

(** The directory separator (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 -> string -> bool
|
|
(** [check_suffix name suff] returns [true] if the filename [name]
|

ends with the suffix [suff]. *)
|
|
|
|
val chop_suffix : string -> 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]. *)

val chop_extension : string -> string
|
|
(** Return the given file name without its extension. The extension

is the shortest suffix starting with a period and not including
|
|
a directory separator, [.xyz] for instance.
|
|
|
|
Raise [Invalid_argument] if the given name does not contain
|
|
an extension. *)
|
|

|
val basename : 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}.
|
|
|
|
The result is not specified if the argument is not a valid file name
|

(for example, under Unix if there is a NUL character in the string). *)

val temp_file : ?temp_dir: string -> string -> string -> string
|
|
(** [temp_file prefix suffix] returns the name of a
|
|
fresh 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].
|
|
The optional argument [temp_dir] indicates the temporary directory
|
|
to use, defaulting to {!Filename.temp_dir_name}.
|
|
The temporary file is created empty, with permissions [0o600]
|
|
(readable and writable only by the file owner). The file is
|
|
guaranteed to be different from any other file that existed when
|
|
[temp_file] was called.

|
val open_temp_file :
|
|
?mode: open_flag list -> ?temp_dir: string -> string -> string -> string * out_channel
|
|
(** Same as {!Filename.temp_file}, but returns both the name of a fresh
|
|
temporary file, and an output channel opened (atomically) on
|
|
this file. This function is more secure than [temp_file]: there
|
|
is no risk that the temporary file will be modified (e.g. replaced
|
|
by a symbolic link) before the program opens it. The optional argument
|
|
[mode] is a list of additional flags to control the opening of the file.
|
|
It can contain one or several of [Open_append], [Open_binary],
|
|
and [Open_text]. The default is [[Open_text]] (open in text mode). *)
|
|
|
|
val temp_dir_name : string
|
|
(** The name of the temporary directory:
|
|
Under Unix, the value of the [TMPDIR] environment variable, or "/tmp"
|
|
if the variable is not set.
|
|
Under Windows, the value of the [TEMP] environment variable, or "."
|
|
if the variable is not set.

|
|
|
|
val quote : string -> string
|
|
(** Return a quoted version of a file name, suitable for use as
|
|
one argument in a command line, escaping all meta-characters.
|
|
Warning: under Windows, the output is only suitable for use
|
|
with programs that follow the standard Windows quoting
|
|
conventions.
