# =head1 DESCRIPTION
# 
# Utilities for encoding and decoding URLs.
# 
# =head1 SUBROUTINES

# 
# Escapes C<$scalar> for the search part of the URL.

# 	[map to_url_param, "a b", "🦁"] # --> [qw/a+b %F0%9F%A6%81/]

# 
# Generates the search portion of the URL.

# 
# =item 1. Keys with C<undef> values are not converted to strings.
# 
# =item 2. The empty value is empty.
# 
# =item 3. The value C<1> is only for a string key.
# 
# =item 4. Keys are converted in alphabetical order.

# 	from_url_params  # --> {a => 1, b => [[1,2],3,{x=>10}]}

# =head2 from_url_param (;$scalar)

# Used to parse keys and values in a URL parameter.
# 
# Reverse to C<to_url_param>.
#

# 	from_url_param  # => ↬
# 
# =head2 parse_url ($url, $onpage, $dir)
# 
# Parses and normalizes URLs.
# 
# =over
# 
# =item * C<$url> - URL or part of it to be parsed.
# 
# =item * C<$onpage> is the URL of the page with C<$url>. If C<$url> is not complete, then it is completed from here. Optional. By default it uses the C<$onpage = 'off://off'> configuration.
# 
# =item * C<$dir> (bool): 1 - normalize the URL path with a "/" at the end if it is a directory. 0 - without "/".
