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.
