Perhaps you'll find the following to be of interest though they are specific to the case of indexing Janet's source code:

• https://github.com/sogaiu/index-janet - pure janet implementation
• https://github.com/sogaiu/index-janet-source - ctags-based implementation

Thank you for sharing! This looks interesting. Actually, I use ludovicchabant/vim-gutentags: A Vim plugin that manages your tag files which calls ctags for me. That's why I'm happy with your ctags configuration for now. But maybe it's even possible to configure vim-gutentags to call idk-janet instead of ctags.

So my take is that removing the bits that look like ,private def might be
a better approach and have updated the gist content.

Thanks for investigating. This approach sounds reasonable!

Thanks for mentioning vim-gutentags. I'd seen it before but not set it up.

FWIW, idk-janet currently works only with Janet's source code (so only this repository). It's not likely to be useful for any other repository.

I tried but didn't make much progress on something that works for typical janet projects (like those that are meant to be installed with jpm). There are limits to what one can pull off statically with a reasonable amount of effort when there is stuff like this. The flexibility of Janet doesn't make creating tooling for it any easier (^^;
