Pandoc is the first thing that comes to mind, but I also believe I have seen an uptick in software that I use being written in Haskell lately, though I can't remember what else off the top of my head.

I don't have the same impression, but https://github.com/PostgREST/postgrest and https://github.com/koalaman/shellcheck are some popular ones that may be useful to hn'ers.

And https://github.com/mchav/dataframe?tab=readme-ov-file#datafr... is a library/framework that has had quite some velocity lately
