Filename - Operations on file names.
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 temporary directory to use, defaulting to the current result of Filename.get_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. 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 Filename.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. You should use Filename.get_temp_dir_name instead. The name of the initial 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. 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.
