This module provides utility functions for dealing with CSS tokens.
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
Printable non-alphanumeric ASCII characters and the space character are
escaped with a single backslash. Other characters are encoded in
"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.
