DESCRIPTION

21       This module provides utility functions for dealing with CSS tokens.
22

FUNCTIONS

24       All functions below that take one argument have a "($)" prototype, so
25       they have the same precedence as "closedir" and "delete".
26
27       escape $string, $chars_to_escape
28           This escapes any characters in $string that occur in
29           $chars_to_escape, which is interpreted as a regular expression. The
30           regexp must consume just one character; otherwise you'll find chars
31           missing from the output. ASCII vertical whitespace (except the
32           vertical tab) is always escaped.
33
34           Printable non-alphanumeric ASCII characters and the space character
35           are escaped with a single backslash. Other characters are encoded
36           in hexadecimal.
37
38           "escape" also considers that you might want to include the escaped
39           string in a larger string, so it appends a space if the escaped
40           string ends with a hexadecimal escape with fewer than six digits.
41
42       unescape $string
43           This turns something like \"H\65llo\" into "Hello" (including
44           quotes).
45
46       escape_ident $string
47       escape_ident $string, $more_chars_to_escape
48           This escapes $string as a CSS identifier, escaping also any
49           characters matched by $more_chars_to_escape.
50
51       unescape_url $url_token
52           Returns the URL that the token represents.
53
54       escape_str $string
55           Returns a CSS string token containing $string (within quotes;
56           characters possibly escaped).
57
58       unescape_str $string_token
59           Returns the value that a CSS string token represents.
