@ -13,3 +13,13 @@ range, so you have to update the ranges every time before

* Experiments
Using regexp by default in treesit-simple-indent-rules seems wasteful,
so I tried replacing all string-match-p to equal in
treesit-simple-indent-presets, and indent xdisp.c for a comparison.
Turns out using regexp by default is faster: regexp-based indent took
45s and equal-based indent took 75s.
I could be missing something, further experiments are welcome.
