Bug report. The snippet below (and associated github gist) says it all. -Sir 20:07 < sirrobert> I'm learning to write grammars, but having a wierd problem. (I think there's something I don't get about newlines or something). 20:07 < sirrobert> https://gist.github.com/2980628 20:08 < pmichaud> \s* doesn't really make sense in a rule 20:08 < sirrobert> ok... 20:08 < pmichaud> since whitespaces in the rule already implies \s* 20:08 < sirrobert> I can't get it to ignore the first part of a slurped file 20:08 < pmichaud> inside of method verb($/), you might want 'eq' instead of '==' 20:09 < sirrobert> oh, yeah 20:10 < sirrobert> Still, adding a blank line at the top of the file breaks it 20:10 < sirrobert> even with the \s* removed 20:10 < pmichaud> looking 20:11 < sirrobert> (cleaned up the gist by replacing == with 'eq' and removed the \s* in all places. Same problem) 20:13 < pmichaud> ah, it's the ^ that's an issue. 20:14 < pmichaud> it's somewhat of a rakudobug; the whitespace before the ^ is eating up the newline before testing for "start of string", and with 'rule' there's no backtracking. 20:14 < sirrobert> ok! 20:14 < pmichaud> I think a recentish spec change causes leading whitespace before a ^ to be ignored... but rakudo doesn't implement that. 20:14 < sirrobert> glad it's not me =) 20:14 < pmichaud> so, eliminate the space before the ^ and maybe it will work. 20:14 < pmichaud> or, switch TOP to be a 'token' instead of a 'rule' 20:15 < sirrobert> ok, great.
