patch to improve style throughput
by Gerd Petermann 02 May '18

Hi Steve, I think I found a simple patch to improve the rule index. I've noticed that the unpatched version often returns far more rules to check than expected. e.g. if an element has the tag a=3 and we have these 3 rules a=1 {...} a=2 & b=1 {...} a=3 & c=1 {...} all three are evaluated, in fact all rules which have a keystring beginning with a= are returned by the index. The patch changes this so that rules which cannot match are not returned. This makes style evaluation a bit faster. I've tried it with a few styles and some input files and found no changes in the output, also all unit tests pass, so I hope I did not miss something. What do you think? Gerd
