This looks like it's about the speed of grep, that sounds incredible.

Still working on a prototype based on tree-sitter would take a week or
two worth of time and I would like to get the metadata fixed now, so
that I can finally move on with runltp-ng. So I would slightly prefer
merging the patches for the current solution first, then we can have a
look on tree-sitter in the next LTP release cycle. What do you think?
