Module Url

module Url: sig .. end
This module provides functions for tampering with Url. It's main goal is to allow one to stay in the Ocaml realm without wandering into the Dom_html.window##.location object.


The first functions are mainly from and to string conversion functions for the different parts of a url.
val urldecode : string -> string
urldecode s swaps percent encoding characters for their usual representation.
val urlencode : ?with_plus:bool -> string -> string
urlencode ?with_plus s replace characters for their percent encoding representation. Note that the '/' (slash) character is escaped as well. If with_plus is true (default) then '+''s are escaped as "%2B". If not, '+''s are left as is.
type http_url = {
   hu_host : string; (*
The host part of the url.
*)
   hu_port : int; (*
The port for the connection if any.
*)
   hu_path : string list; (*
The path splitted on '/' characters.
*)
   hu_path_string : string; (*
The original entire path.
*)
   hu_arguments : (string * string) list; (*
Arguments as a field-value association list.
*)
   hu_fragment : string; (*
The fragment part (after the '#' character).
*)
}
The type for HTTP(s) url.
type file_url = {
   fu_path : string list;
   fu_path_string : string;
   fu_arguments : (string * string) list;
   fu_fragment : string;
}
The type for local file urls.
type url = 
| Http of http_url (*
Non secure HTTP urls
*)
| Https of http_url (*
Secure HTTPS urls
*)
| File of file_url (*
Local files
*)
The type for urls.
val default_http_port : int
The default port for Http communications (80).
val default_https_port : int
The default port for Https communications (443).
val path_of_path_string : string -> string list
path_of_path_string s splits s on each "/" character.
val encode_arguments : (string * string) list -> string
encode_arguments a expects a list of pair of values of the form (name,value) were name is the name of an argument and value it's associated value.
val decode_arguments : string -> (string * string) list
decode_arguments s parses s returning the sliced-diced association list.

The following part allow one to handle Url object in a much higher level than what a string provides.
val url_of_string : string -> url option
url_of_string s parses s and builds a value of type url if s is not a valid url string, it returns None.
val string_of_url : url -> string
string_of_url u returns a valid string representation of u. Note that * string_of_url ((fun Some u -> u) (url_of_string s)) is NOT necessarily * equal to s. However url_of_string (string_of_url u) = u.
module Current: sig .. end
This module can be used to handle the Url associated to the current document.
