So, really cool new tool I’ve learning as I’m working with lisp for my startup: symex.el for structural navigation and editing is VERY efficient, somewhat vim-based, and I really like it a lot. As an added bonus, some of its dependencies (e.g. lispy) are very useful for multi-lining s-exps (aka symexs) and formatting them, and it plays nicely with sly, which is even better!
Additionally, for all you #rstats people out there (who are asking why I included the tag on a post about Lisp), maybe take a quick look at this. I’m currently using it myself, and I’ve found it’s pretty good for most basic things, and you may like it if you give it a try (or maybe not, it’s not yet as full featured as R and its various packages yet, but it does benefit from some things I don’t think you can get easily from R). Also, here’s a super quick demo thingy(?).
I know other tools leveraging tree-sitter try to achieve similar functionality, but when the code is already in an AST format, it really eliminates the guesswork and makes the experience seamless!
