Show HN: Alumina Programming Language
Honestly, Tree Sitter is fantastic, I can highly recommend it. By far the most user friendly and powerful parser generator I've worked with. The C API is very nice.
The only two pain point I had is that the `node-types.json` that's generated only contains the names of the nodes, not the numerical IDs. This means that if you have some codegen generating Rust enums is difficult if you want to avoid matching nodes by string.
I wrote https://github.com/tibordp/tree-sitter-visitor for generating visitor traits in Rust for a given grammar. I actually did it a bit differently in the end for Alumina, but it might come useful.

Ask HN: What are some unpopular technologies you wish people knew more about?
(1) Zulip Chat - https://zulip.com/ - seems to be reasonably popular, but more people should know about it
I’ve been using it for over 5 years now [1], and it’s as good as ever. It’s way faster than any other chat app I’ve used. It has a good UI and conversation model. It has a simple and functional API that lets me curl threads and write blog posts based on them.
(only problem is that I Ctrl-+ in my browser to make the font bigger – I think it’s too dense for most people)
(2) re2c regex to state machine compiler - https://re2c.org
A gem from the 90’s, which people have done a great job maintaining and improving (getting Go and Rust target support in the last few years). I started using it in 2016, and used for a new program a few months ago. I came to the conclusion that it should have been built into C, because C has shitty string processing – and Ken Thompson both invented C AND brought regular languages to computing !!
In comparison, treesitter lexers are very low level, fiddly, and error prone. I recently saw dozens of ad hoc fixes to the tree-sitter-bash lexer, which is unsurprising if you look at the structure of the code (manually crawling through backslashes and braces in C).
https://github.com/tree-sitter/tree-sitter-bash/blob/master/...
These fixes are definitely appreciated, but I think it indicates a problem with the model itself.

Treesiter problem with .bashrc
I ran into this issue as well a few weeks ago, there's already a few issues for it: https://github.com/tree-sitter/tree-sitter-bash/issues/151

Convert curl commands to code in several languages
All 3 of these are linked to under "Related Tools".
Those projects use a pretty basic tokenizer
https://github.com/luckymarmot/Paw-cURLImporter/blob/master/...
Insomnia and Postman use commander.js for their bash parsing which looks like it just splits on space:
https://github.com/tj/commander.js/blob/02a124c7d58dbae2ef11...
and only support a few of curl's options. Curlconverter uses tree-sitter's Bash grammar https://github.com/tree-sitter/tree-sitter-bash/ and tries to at least correctly discard all of curl's options and any options that curl used to have.
What are some alternatives?
