Module File_path.Absolute

Absolute paths are a subtype of Path.t and therefore also of string.

Path types have straightforward to_string and sexp_of_t behavior. of_string and t_of_sexp raise on invalid input (e.g. containing null characters), and guarantee canonical output (e.g. no redundant slashes).

to_string is the identity function. of_string returns its input when the input is a valid string in canonical form.

val __bin_read_t__ : t Bin_prot.Read.vtag_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 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 @@ portable

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 @@ portable
val between : t -> low:t -> high:t -> bool @@ portable

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

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

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 : t @@ portable

The root directory, i.e. /.

val basename : t -> Types.Part.t option @@ portable

Returns the final part of the given path, or None if given root.

val basename_exn : t -> Types.Part.t @@ portable

Returns the final part of the given path, or raises if given root.

val basename_or_error : t -> Types.Part.t Core.Or_error.t @@ portable

Returns the final part of the given path, or returns an error if given root.

val basename_defaulting_to_dot : t -> Types.Part.t @@ portable

Returns the final part of the given path, or Part.dot if given root.

val dirname : t -> t option @@ portable

Returns all parts of the given path but the final one, or None if given root.

val dirname_exn : t -> t @@ portable

Returns all parts of the given path but the final one, or raises if given root.

val dirname_or_error : t -> t Core.Or_error.t @@ portable

Returns all parts of the given path but the final one, or returns an error if given root.

val dirname_defaulting_to_root : t -> t @@ portable

Returns all parts of the given path but the final one, or root if given root.

val dirname_and_basename : t -> (t * Types.Part.t) option @@ portable

Like Option.both (dirname t) (basename t). Allocates Some at most once.

val append_to_basename_exn : t -> string -> t @@ portable

Adds the given string as a suffix of the path's basename. Raises if t is root and therefore has no basename, or if the string contains characters that are illegal for a path part.

val append_part : t -> Types.Part.t -> t @@ portable

Adds a part to the end of the path.

val append : t -> Types.Relative.t -> t @@ portable

Appends the parts of a relative path to the end of the absolute path.

val is_prefix : t -> prefix:t -> bool @@ portable

Reports if the parts of prefix are a non-strict prefix of the parts of the other argument.

val is_suffix : t -> suffix:Types.Relative.t -> bool @@ portable

Reports if the parts of suffix are a non-strict suffix of the parts of the other argument.

val chop_prefix : t -> prefix:t -> Types.Relative.t option @@ portable

Returns all parts of the given path after prefix, or None if prefix is not a prefix of the path's parts. If the path equals prefix, returns Relative.dot.

val chop_prefix_exn : t -> prefix:t -> Types.Relative.t @@ portable

Returns all parts of the given path after prefix, or raises if prefix is not a prefix of the path's parts. If the path equals prefix, returns Relative.dot.

val chop_prefix_or_error : t -> prefix:t -> Types.Relative.t Core.Or_error.t @@ portable

Returns all parts of the given path after prefix, or returns an error if prefix is not a prefix of the path's parts. If the path equals prefix, returns Relative.dot.

val chop_suffix : t -> suffix:Types.Relative.t -> t option @@ portable

Returns all parts of the given path before suffix, or None if suffix is not a suffix of the path's parts.

val chop_suffix_exn : t -> suffix:Types.Relative.t -> t @@ portable

Returns all parts of the given path before suffix, or raises if suffix is not a suffix of the path's parts.

val chop_suffix_or_error : t -> suffix:Types.Relative.t -> t Core.Or_error.t @@ portable

Returns all parts of the given path before suffix, or returns an error if suffix is not a suffix of the path's parts.

val chop_suffix_if_exists : t -> suffix:Types.Relative.t -> t @@ portable

Returns all parts of the given path before suffix, or returns the path unchanged if suffix is not a suffix of the path's parts.

val simplify_dot : t -> t @@ portable

Removes . parts from the given path.

val simplify_dot_and_dot_dot_naively : t -> t @@ portable

Removes . parts from the given path. Cancels out .. parts with preceding parts (that are neither . nor ..). Removes any .. parts immediately following the leading /. Does not check the file system; in the presence of symlinks, the resulting path may not be equivalent.

val to_parts : t -> Types.Part.t list @@ portable

Produces the parts of the path.

val of_parts : Types.Part.t list -> t @@ portable

Constructs an absolute path from the given parts.

val number_of_parts : t -> int @@ portable

Equivalent to List.length (to_parts t), without allocating.
