As reported in https://github.com/mawww/kakoune/issues/4685#issuecomment-1200530001 ledger.kak defines a region end that matches every character of the buffer. This causes performance issues for large buffers. Since the affected regions are only ever filled with a single color, just use a regex highlighter instead of a region highlighter. This improves performance when loading the file for the first time. Speedup on [example.journal.txt](https://github.com/mawww/kakoune/issues/4685#issuecomment-1193243588) $ HOME=$PWD hyperfine -w 1 'git checkout HEAD'{~,}' -- :/rc/filetype/ledger.kak && ./kak.opt example.journal.txt -e "modeline-parse; hook global NormalIdle .* quit" -ui dummy' Benchmark 1: git checkout HEAD~ -- :/rc/filetype/ledger.kak && ./kak.opt example.journal.txt -e "modeline-parse; hook global NormalIdle .* quit" -ui dummy Time (mean ± σ): 362.1 ms ± 5.1 ms [User: 336.6 ms, System: 30.2 ms] Range (min … max): 352.6 ms … 369.1 ms 10 runs Benchmark 2: git checkout HEAD -- :/rc/filetype/ledger.kak && ./kak.opt example.journal.txt -e "modeline-parse; hook global NormalIdle .* quit" -ui dummy Time (mean ± σ): 271.2 ms ± 16.7 ms [User: 252.8 ms, System: 24.0 ms] Range (min … max): 253.9 ms … 305.0 ms 10 runs Summary 'git checkout HEAD -- :/rc/filetype/ledger.kak && ./kak.opt example.journal.txt -e "modeline-parse; hook global NormalIdle .* quit" -ui dummy' ran 1.33 ± 0.08 times faster than 'git checkout HEAD~ -- :/rc/filetype/ledger.kak && ./kak.opt example.journal.txt -e "modeline-parse; hook global NormalIdle .* quit" -ui dummy'
