How to get highlighting back like in original ctrlp?

[svenstaro]

So the original ctrlp will give me a neat partial highlight during matching. I wonder whether I can somehow get that back? It's useful to see exactly where I'm matching and also it looks neat.

In principle we can determine the set of matched characters in all of the top results, emit Vim regexes that match them precisely with \zs and \ze, and then matchadd() those regexes to highlight them (like CtrlP does). The tricky part is actually determining the matched bytes; before matching, match items are split into path components and then (optionally) decoded from UTF-8 to Unicode code points as they're used, and these are what are matched on, so we'd have to translate code point and path component position back to byte position to build the regex.

I'm currently working matcher-color on ctrlp.vim

https://github.com/ctrlpvim/ctrlp.vim/tree/matcher-color

could you add new option to add color attribute for g:ctrlp_matcher_func?

let g:ctrlp_match_func = {'match': 'cpsm#CtrlPMatch', 'color': 1}

This highlight text from \zs to \ze.

This color may be changed to highlight. I'm not sure.

mattn, if I understand what you mean, I don't think the color/highlight attribute you have is enough for the kind of highlighting I'd like, because it only allows a single contiguous match to be highlighted per line; cpsm regularly matches in multiple groups.
