Yorhel was also the creator/developer of ncdu among many other open source projects. He was a big open source advocate. The sites he hosted (vndb.org and manned.org) have automated database dumps and source code fully available. Recommend to check out his website https://dev.yorhel.nl/
ncdu is a lifesaver, RIP.
There's a Yomitan dictionary (by bee) of VNDB using those dumps: https://github.com/bee-san/VNDB-Character-Names-by-Bee
Wow a few years ago I wanted to resurrect some of my old code, to do essentially what ncdu does
Then I found ncdu, and haven’t looked back since. So it saved me a lot of time
Thank you and RIP
