module Types : Types.S

Everything below uses the types and subtyping relationships of Types.

module Part : Part.S with module Types := Types
module Relative : Relative.S with module Types := Types
module Absolute : Absolute.S with module Types := Types

Paths are a subtype of string.

type t = Types.Path.t
type comparator_witness = Types.Path.comparator_witness

module Expert : sig ... end

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 append : t -> Types.Relative.t -> t

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

Reports if the parts of prefix are a non-strict prefix of the parts of the other argument, and the paths are both absolute or both relative.

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

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

Returns all parts of the given path after prefix, or None if prefix is not a prefix of the path's parts. Always returns None if the path and prefix do not match in absolute/relative status. If the path equals prefix, returns dot.

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

Returns all parts of the given path after prefix, or raises if prefix is not a prefix of the path's parts. Always raises if the path and prefix do not match in absolute/relative status. If the path equals prefix, returns dot.

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

Returns all parts of the given path after prefix, or returns an error if prefix is not a prefix of the path's parts. Always returns an error if the path and prefix do not match in absolute/relative status. If the path equals prefix, returns dot.

val chop_prefix_if_exists : t -> prefix:t -> t

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

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