TBH I have mostly done so in JSON filters written in Perl, but now that lpeg and re are available in Lua filters they are a serious contender too. A tip: if custom bits in syntax X are much more common than actual code elements it makes sense to leave the former unmarked and give the latter a pseudo-class `.code` if you don't want them highlighted. /bpj Den tis 21 dec. 2021 09:52 <denis.maier-NSENcxR/0n0@public.gmane.org> skrev: > That's maybe true.
