Filename(3) OCaml library Filename(3)NAME
Filename - Operations on file names.
Module
Module Filename
Documentation
Module Filename
: sig end
Operations on file names.
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).
val dir_sep : string
The directory separator (e.g. / in Unix).
Since 3.11.2
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. If name is a valid file name, then 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 .
This function conforms to the specification of POSIX.1-2008 for the basename utility.
val dirname : string -> string
See Filename.basename . This function conforms to the specification of POSIX.1-2008 for the dirname utility.
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 tempo-
rary directory to use, defaulting to the current result of Filename.get_temp_dir_name . The temporary file is created empty, with permis-
sions 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. Raise Sys_error if the file could not be created.
Before3.11.2 no ?temp_dir optional argument
val open_temp_file : ?mode:Pervasives.open_flag list -> ?temp_dir:string -> string -> string -> string * Pervasives.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). Raise Sys_error if the file
could not be opened.
Before3.11.2 no ?temp_dir optional argument
val get_temp_dir_name : unit -> 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. The temporary directory can be changed with File-
name.set_temp_dir_name .
Since 4.00.0
val set_temp_dir_name : string -> unit
Change the temporary directory returned by Filename.get_temp_dir_name and used by Filename.temp_file and Filename.open_temp_file .
Since 4.00.0
val temp_dir_name : string
Deprecated. The name of the initial temporary directory: Under Unix, the value of the TMPDIR environment variable, or "/tmp" if the vari-
able is not set. Under Windows, the value of the TEMP environment variable, or "." if the variable is not set. This function is depre-
cated; Filename.get_temp_dir_name should be used instead.
Since 3.09.1
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.
