Package gorilla/css/scanner generates tokens for a CSS3 input.
It follows the CSS3 specification located at:
http://www.w3.org/TR/css3-syntax/
To use it, create a new scanner for a given CSS string and call Next() until
the token returned has type TokenEOF or TokenError:
s := scanner.New(myCSS)
for {
token := s.Next()
if token.Type == scanner.TokenEOF || token.Type == scanner.TokenError {
break
}
// Do something with the token...
}
Following the CSS3 specification, an error can only occur when the scanner
finds an unclosed quote or unclosed comment. In these cases the text becomes
"untokenizable". Everything else is tokenizable and it is up to a parser
to make sense of the token stream (or ignore nonsensical token sequences).
Note: the scanner doesn't perform lexical analysis or, in other words, it
doesn't care about the token context. It is intended to be used by a
lexer or parser.
