Bozhidar Batsov (a.k.a. Bug)

Release v0.4.0 · bbatsov/neocaml Bug fixes #20: Work around broken transpose-sexps on Emacs 30 (bug#60655). Falls back to default transpose behavior; Emacs 31 has a proper fix. #22: Fix compilation regexp to handle arbitrary lead...

neocaml 0.4 is out with many small improvements and a few bug-fixes github.com/bbatsov/neoc...

Thanks to everyone who provided valuable feedback since the last release!

I'm running out of ideas for what to improve at this point, so I guess version 1.0 is now in sight. 😁

Emacs and Vim in the Age of AI It’s tough to make predictions, especially about the future. – Yogi Berra

I jotted down some thoughts on the future of editors like #Emacs and #Vim in the age of AI batsov.com/articles/202...

I'd be very curious to hear your thoughts on the subject as well.

I think this gap is EXTREMELY real in a business sense and yet there is also the revealed other thing here which is a great deal of people in the world will never be remotely of interest to SaaS, and we know it, and those people still have needs suited to software

Look, it's a mess out there and you can react to that mess by deciding everyone else is a moron or you could react to it by deciding most people are trying to get by with a different context than yours and start working the problem. Those are your choices pretty much, can't choose "no mess"

Mastering Compilation Mode I’ve been using Emacs for over 20 years. I’ve always used M-x compile and next-error without thinking much about them – you run a build, you jump to errors, life is good. But recently, while working o...

That's going to be pretty handy going forward!

Transpose All The Things Most Emacs users know C-t to swap two characters and M-t to swap two words. Some know C-x C-t for swapping lines. But the transpose family goes deeper than that, and with tree-sitter in the picture, t...

Another day, another batch of #Emacs tips & tricks for you emacsredux.com/blog/2026/03...

Glad to hear this! And yeah - with Emacs we're all constant learners. :-)

expreg: Expand Region, Reborn expand-region is one of my all time favorite Emacs packages. I’ve been using it since forever – press a key, the selection grows to the next semantic unit, press again, it grows further. Simple, usefu...

expreg is a great alternative to expand-region, that's #TreeSitter aware. I can't believe I didn't discover it earlier! (technically speaking - I discovered it last year, but I forgot to update my init.el to actually use it :D )

#Emacs

Neocaml got mentioned on HackerNews yesterday news.ycombinator.com/item?id=4718...

I hope this will inspire more people to check it out!

#Emacs #OCaml

I didn't notice much of a difference to be honest, but I guess it also depends on the language that you're using (e.g. for ast-grep). I still have some note to look more closely into how Claude decides which tools to use in which context.

Developer productivity will suffer today...

Building Emacs Major Modes with TreeSitter: Lessons Learned Over the past year I’ve been spending a lot of time building TreeSitter-powered major modes for Emacs – clojure-ts-mode (as co-maintainer), neocaml (from scratch), and asciidoc-mode (also from scratch...

I've converted some random dev notes I had lying around from working on clojure-ts-mode, neocaml and asciidoc-mode to a blog post with some general advice for building #Emacs major modes powered by #TreeSitter batsov.com/articles/202...

I hope you'll find it useful!

Thanks! neocaml was a very fund journey so far and I'm really happy that it's already being used by people other than me! :D

#Ruby

Brutal times for an industry that was once considered bulletproof... But I guess that if tobacco companies managed to endure, the spirit makes will manage to find some path forward as well.

There are so many ways to work with code comments in #Emacs emacsredux.com/blog/2026/02...

While working on neocaml, I learned more about comments than I ever wanted to know.

Oh, well... 😅

How to Vim: Build your .vimrc from Scratch You don’t need a massive .vimrc to be productive in Vim.

I must be a really bad Emacser these days, as I keep having fun every now and then with #Vim. :D

I finally finished an article on starting out your Vim config that has been on backburner for over half a year batsov.com/articles/202...

Enjoy!

This must be one of the best articles about #RuboCop I ever came across lovro-bikic.github.io/300-days-of-...

It made really proud of the work we've done with the project, and the great community around it!

GitHub - bbatsov/asciidoc-mode: A modern Emacs major mode for editing AsciiDoc files, powered by TreeSitter A modern Emacs major mode for editing AsciiDoc files, powered by TreeSitter - bbatsov/asciidoc-mode

I've put together asciidoc-mode (github.com/bbatsov/asci...) - a super lean major #Emacs mode for editing #AsciiDoc documents, powered by #TreeSitter

It's a lighter and simpler alternative to the more established adoc-mode (also maintained by yours truly), that I've been meaning to do for a while.

CIDER - still the one dev env that Clojurians love the most... and the second one is our dear sibling project Calva!

It's great to see CIDER staying competitive for so many years, given the growing number of awesome alternatives!

It features a few small improvements and a dedicated edn-mode (a lighter version of clojure-mode for better performance in large files)

Hot on the heels of the first "official" #neocaml release, I'm very pleased to share that neocaml 0.2 is out today with many improvements! (see the release notes for details github.com/bbatsov/neoc...)
