Not sure if the author is on lobste.rs, but are there any plans to support Golang in the future?
The author seems to encourage adding new languages on your own – see the “Adding a Language” section in the readme. If you end up implement support for Golang, I’d consider submitting it as a patch. I think there are a lot of people who would appreciate support for that out of the box
Sadly, I’m not going to be able to make time for that :(
