## This module implements URI parsing as specified by RFC 3986.
##
## A Uniform Resource Identifier (URI) provides a simple and extensible
## means for identifying a resource. A URI can be further classified
## as a locator, a name, or both. The term “Uniform Resource Locator”
## (URL) refers to the subset of URIs.
##
## Basic usage
## ===========
##
## Combine URIs
## -------------
## .. code-block::
##    import uri
##    let host = parseUri("https://nim-lang.org")
##    let blog = "/blog.html"
##    let bloguri = host / blog
##    assert $host == "https://nim-lang.org"
##    assert $bloguri == "https://nim-lang.org/blog.html"
##
## Access URI item
## ---------------
## .. code-block::
##    import uri
##    let res = parseUri("sftp://127.0.0.1:4343")
##    if isAbsolute(res):
##      assert res.port == "4343"
##    else:
##      echo "Wrong format"

import strutils, parseutils
type
  Url* = distinct string

  Uri* = object
    scheme*, username*, password*: string
    hostname*, port*, path*, query*, anchor*: string
    opaque*: bool

proc encodeUrl*(s: string, usePlus=true): string =
  ## Encodes a URL according to RFC3986.
  ##
  ## This means that characters in the set
  ## ``{'a'..'z', 'A'..'Z', '0'..'9', '-', '.', '_', '~'}`` are
  ## carried over to the result.
  ## All other characters are encoded as ``%xx`` where ``xx``
  ## denotes its hexadecimal value.
  ##
  ## As a special rule, when the value of ``usePlus`` is true,
  ## spaces are encoded as ``+`` instead of ``%20``.
  ##
  ## **See also:**
  ## * `decodeUrl proc<#decodeUrl,string>`_
  runnableExamples:
    assert encodeUrl("https://nim-lang.org") == "https%3A%2F%2Fnim-lang.org"

    of ' ': add(result, fromSpace)
    else:
      add(result, '%')
      add(result, toHex(ord(c), 2))

proc decodeUrl*(s: string, decodePlus=true): string =
  ## Decodes a URL according to RFC3986.
  ##
  ## This means that any ``%xx`` (where ``xx`` denotes a hexadecimal
  ## value) are converted to the character with ordinal number ``xx``,
  ## and every other character is carried over.
  ##
  ## As a special rule, when the value of ``decodePlus`` is true, ``+``
  ## characters are converted to a space.
  ##
  ## **See also:**
