Using the enum rather than string comparisons as the match progresses should save cycles.
- Don't use strtok -- we only care about the last token anyway which means we can just find where that token begins. - If we are scanning rather than tokenizing we can look for both '\\' and '/' so we don't need to modify the string. - If we don't modify the string we don't need to make a copy.

There was a problem hiding this comment.
Crashes for me. I think it should be while (*scan != '\0').

@telemenar This is good stuff, thanks! I forked your repo to https://github.com/ptzz/ctrlp-cmatcher and optimised further. Managed to cut the processing time by ~80% for large input. The delay is not really noticeable now for 100k files on a 2012 Macbook. The trick was to use partial sort and only sort the items visible on screen. |

This makes a number of performance improvements avoiding largely copying and additional comparison.
The two most significant pieces are:
