modeline-parse leads by matching an expensive regex against the entire buffer, which can take a long time on huge files. Perl takes too long on this regex and it seems not even ripgrep optimizes the \z component $ ruby -e '10000.times { puts "a" * 10000 }' > big $ time rg --multiline --only-matching '\A(.+\n){1,5}|(.+\n){1,5}\z' big | wc -l 10 __________________________ Executed in 419.81 millis usr time 399.84 millis sys time 20.78 millis where $ time kak big -e q __________________________ Executed in 179.19 millis usr time 133.61 millis sys time 53.50 millis Let's lose the regex.
