Bozhidar Batsov (a.k.a. Bug)

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...

Friday night is the best time to learn more about #Emacs emacsredux.com/blog/2026/03...

Без коментар. 😂

I definitely didn't see this coming! #hhkb

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

RuboCop 1.85 is out! (github.com/rubocop/rubo...)

It features many new cops, a built-in MCP server and many small fixes and improvements! The user docs have been reorganized and improved a lot as well!

Enjoy!

#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!
#Emacs #Clojure

That’s one of the best articles on the potential issues with relying too much on #AI tooling / #LLMs for programming blog.fogus.me/meta/LLMe.html

The #Clojure community has always been fascinating with its depth and thoughtfulness!

Вероятно е комбинация от двете.

Release v5.21.0 · clojure-emacs/clojure-mode New features #650: Add edn-mode, a lightweight mode derived from clojure-mode with data-appropriate indentation for .edn files. #439: Add interpreter-mode-alist entries for clojure, clj, planck, j...

A new version of clojure-mode is out github.com/clojure-emac...

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

Enjoy!

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...)

Thanks to everyone who tested v0.1 and provided valuable feedback! You rock!

#OCaml #Emacs

So it would seem - I'm reading its documentation right now. I'm still a slow learner. :D

A problem that solves itself - my favorite kind! :D

I asked my #ClaudeCode which CLI tools it would benefit from and it wrote a blog post on the subject batsov.com/articles/202... 😁

Funny enough I hadn't even heard of some of tools it suggested.

Hmm, that's weird - likely something to do with the yasnippet configuration.

Can you open an issue on GitHub with more details about the problem your yas config?
