Wow how did you find all these? Have you been keeping track all these years, or did you somehow search for and find this just now?

All today. I have been trying to carefully craft searches on Google and Stack Overflow. I wish Google Code Search were still around, or that Github code search were better.

I always get it confused with self-hosted https://github.com/CoatiSoftware/Sourcetrail but I think Sourcetrail just shut down.
