val __bin_read_t__ : (int -> t) Bin_prot.Read.reader

This function only needs implementation if t exposed to be a polymorphic variant. Despite what the type reads, this does *not* produce a function after reading; instead it takes the constructor tag (int) before reading and reads the rest of the variant t afterwards.

val (=) : t -> t -> bool
val (>) : t -> t -> bool
val (<) : t -> t -> bool
val (<>) : t -> t -> bool
val equal : t -> t -> bool
val compare : t -> t -> int

compare t1 t2 returns 0 if t1 is equal to t2, a negative integer if t1 is less than t2, and a positive integer if t1 is greater than t2.

val min : t -> t -> t
val max : t -> t -> t
val ascending : t -> t -> int

ascending is identical to compare. descending x y = ascending y x. These are intended to be mnemonic when used like List.sort ~compare:ascending and List.sort ~cmp:descending, since they cause the list to be sorted in ascending or descending order, respectively.

val descending : t -> t -> int
val between : t -> low:t -> high:t -> bool

between t ~low ~high means low <= t <= high

val clamp_exn : t -> min:t -> max:t -> t

clamp_exn t ~min ~max returns t', the closest value to t such that between t' ~low:min ~high:max is true.

Raises if not (min <= max).

val root : Core_kernel__.Import.string

The path of the root.

Pathname resolution

val is_posix_pathname_component : Core_kernel__.Import.string -> Core_kernel__.Import.bool

is_posix_pathname_component f


true if f is a valid path component on a POSIX compliant OS

Note that this checks a path component, and not a full path.

val temp_dir_name : Core_kernel__.Import.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 current_dir_name : Core_kernel__.Import.string

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

val parent_dir_name : Core_kernel__.Import.string

The conventional name for the parent of the current directory (e.g. .. in Unix).

val dir_sep : Core_kernel__.Import.string

The directory separator (e.g. / in Unix).

val concat : Core_kernel__.Import.string -> Core_kernel__.Import.string -> Core_kernel__.Import.string

concat p1 p2 returns a path equivalent to p1 ^ "/" ^ p2. In the resulting path p1 (resp. p2) has all its trailing (resp. leading) "." and "/" removed. eg: concat "a/." ".//b" => "a/b" concat "." "b" => "./b" concat "a" "." => "a/." concat "a" "/b" => "a/b"

@throws Failure if p1 is empty.

val is_relative : Core_kernel__.Import.string -> Core_kernel__.Import.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_absolute : Core_kernel__.Import.string -> Core_kernel__.Import.bool
val is_implicit : Core_kernel__.Import.string -> Core_kernel__.Import.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 : Core_kernel__.Import.string -> Core_kernel__.Import.string -> Core_kernel__.Import.bool

check_suffix name suff returns true if the filename name ends with the suffix suff.

val chop_suffix : Core_kernel__.Import.string -> Core_kernel__.Import.string -> Core_kernel__.Import.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 : Core_kernel__.Import.string -> Core_kernel__.Import.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 split_extension : Core_kernel__.Import.string -> Core_kernel__.Import.string * Core_kernel__.Import.string Core_kernel__.Import.option

split_extension fn return the portion of the filename before the extension and the (optional) extension. Example: split_extension "/foo/my_file" = ("/foo/my_file", None) split_extension "/foo/my_file.txt" = ("/foo/my_file", Some "txt") split_extension "/home/c.falls/my_file" = ("/home/c.falls/my_file", None)

val basename : Core_kernel__.Import.string -> Core_kernel__.Import.string

Respects the posix semantic.

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 dirname : Core_kernel__.Import.string -> Core_kernel__.Import.string

See Filename.basename.

val split : Core_kernel__.Import.string -> Core_kernel__.Import.string * Core_kernel__.Import.string

split filename returns (dirname filename, basename filename)

val parts : Core_kernel__.Import.string -> Core_kernel__.Import.string Core_kernel__.Import.list

parts filename returns a list of path components in order. For instance: /tmp/foo/bar/baz -> "/"; "tmp"; "foo"; "bar"; "baz". The first component is always either "." for relative paths or "/" for absolute ones.

val of_parts : Core_kernel__.Import.string Core_kernel__.Import.list -> Core_kernel__.Import.string

of_parts parts joins a list of path components into a path. It does roughly the opposite of parts, but they fail to be precisely mutually inverse because of ambiguities like multiple consecutive slashes and . components.

Raises an error if given an empty list.

val quote : Core_kernel__.Import.string -> Core_kernel__.Import.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.

See Sys.quote for an alternative implementation that is more human readable but less portable.
