VERSION
Version 0.17

SYNOPSIS
  use CSS::DOM::Util ':all';
  # or:

    escape unescape
    escape_ident unescape_url
    escape_str unescape_str
  ];

DESCRIPTION
This module provides utility functions for dealing with CSS tokens.

FUNCTIONS
All functions below that take one argument have a "($)" prototype, so they have the same precedence as "closedir" and "delete".

escape $string, $chars_to_escape
    This escapes any characters in $string that occur in $chars_to_escape, which is interpreted as a regular expression. The regexp must consume just one character; otherwise you'll find chars missing from the output. ASCII vertical whitespace (except the vertical tab) is always escaped.

    Printable non-alphanumeric ASCII characters and the space character are escaped with a single backslash. Other characters are encoded in hexadecimal.

    "escape" also considers that you might want to include the escaped string in a larger string, so it appends a space if the escaped string ends with a hexadecimal escape with fewer than six digits.

unescape $string
    This turns something like \"H\65llo\" into "Hello" (including quotes).

escape_ident $string
escape_ident $string, $more_chars_to_escape
    This escapes $string as a CSS identifier, escaping also any characters matched by $more_chars_to_escape.

unescape_url $url_token
    Returns the URL that the token represents.

escape_str $string
    Returns a CSS string token containing $string (within quotes; characters possibly escaped).

unescape_str $string_token
    Returns the value that a CSS string token represents.
