nl_tokens: Consumes content inside round braces . Mostly used to skip ; token inside expressions since in LESS it is also used to separate function arguments
pl_tokens: function eatBraces ( stream , root ) { if ( stream . eat ( LBRACE ) ) { let stack = 1 , token ; while ( ! stream . eof ( ) ) { if ( stream . eat ( RBRACE ) ) { stack -- ; if ( ! stack ) { break ; } } else if ( stream . eat ( LBRACE ) ) { stack ++ ; } else if ( eatUrl ( stream ) || eatString ( stream ) ) { <mask> ; } else if ( token = comment ( stream ) ) { root . addComment ( token ) ; continue ; } else { stream . next ( ) ; } } return true ; } return false ; }
