| * Use a specialized token_idx_next.Sjoerd Job Postmus2016-06-121-4/+4
| | | | | | | | Prevent calling token_index.
| * Index-based token_idx_prevSjoerd Job Postmus2016-06-121-2/+3
| | | | | | | | | | Prevent some more calls to token_index in group_identifier_list. They are now all gone.
| * Use specialized token_idx_next_by in group_aliased.Sjoerd Job Postmus2016-06-121-6/+4
| | | | | | | | | | | | | | | | | | | | The method group_aliased was making a lot of calls to token_index. By specializing token_next_by to token_idx_next_by, the calls to token_index became superfluous. Also use token_idx_next_by in group_identifier_list. It was making a lot of calls, which is now more than reduced in half.
| * Re-use token index in group_identifier.Sjoerd Job Postmus2016-06-121-8/+13

| * Replace _group_matching with an inward-out grouping algorithmSjoerd Job Postmus2016-06-121-8/+20
| | | | | | | | | | | | | | | | | | | | | | All the matching between open/close was done all the time, first finding the matching closing token, and then grouping the tokens in between, and recurse over the newly created list. Instead, it is more efficient to look for the previous open-token on finding a closing-token, group these two together, and then continue on. squashed: Handle token indices in group_tokens_between and find_matching.
| * Special-case group_tokens(..., tokens_between())Sjoerd Job Postmus2016-06-121-24/+14
| | | | | | | | | | | | When having been guaranteed that the tokens form a range, it is possible to get rid of a lot of calls to `Token.tokens.remove(...)` which are expensive.
| * Call `Token`-methods index based.Sjoerd Job Postmus2016-06-121-24/+26
| | | | | | | | | | | | | | | | | | | | A lot of methods have token-to-idx magic due to `Token._find_matching` converting tokens to indexes. Unknowingly, this turns innocent looking algorithms into O(n^2) (or worse). This does not solve the problem, but makes it more clear by moving the call to `Token.token_index` obvious at the call-site, at the cost of repeating it over-and-over.
