  Batppuccin and Tokyo Night Themes Land on MELPA

  Quick heads-up: my two newest Emacs themes are now on MELPA, so installing them is a plain old package-install away.

  • batppuccin is my take on the popular Catppuccin palette. Four flavors (mocha, macchiato, frappe, latte) across the dark-to-light spectrum, each defined as a proper deftheme that plays nicely with load-theme and theme-switching packages.
  • tokyo-night is a faithful port of folke’s Tokyo Night, with all four upstream variants included (night, storm, moon, day).

  Both themes come with broad face coverage out of the box (e.g. magit, vertico, corfu, marginalia, transient, flycheck, doom-modeline, and many, many more), a shared palette file per package, and the usual *-select, *-reload, and *-list-colors helpers.

  Installation is now as simple as you’d expect:

  (use-package batppuccin-theme
    :ensure t
    :config
    (load-theme 'batppuccin-mocha t))
  
  (use-package tokyo-night-theme
    :ensure t
    :config
    (load-theme 'tokyo-night t))
  

  If you’re curious about the design decisions behind these themes, I’ve covered the rationale in a couple of earlier posts. Batppuccin: My Take on Catppuccin for Emacs explains why I bothered with another Catppuccin port when an official one already exists. Creating Emacs Color Themes, Revisited zooms out to the broader topic of building and maintaining Emacs themes in 2026.

  Give them a spin and let me know what you think. That’s all I have for you today. Keep hacking!

  Stealing from the Best Emacs Configs

  Good artists borrow, great artists steal.

  – Pablo Picasso

  After spending the past couple of weeks updating Prelude and my personal Emacs config, I figured it wouldn’t hurt to see what the competition has been up to. I hadn’t done a proper survey of other people’s configs in years, and the Emacs landscape has changed quite a bit since the last time I looked.

  So I went through Doom Emacs, Purcell’s emacs.d, Centaur Emacs, Prot’s dotfiles, and a handful of others. Here are some of the most interesting things I found – settings and tricks that I either didn’t know about or had forgotten about entirely.

  The Many Faces of flet: cl-flet, cl-labels, and cl-letf

  Way back in 2013 I wrote about the deprecation of flet and how noflet could fill the gap. Thirteen years later, it’s probably time for a proper overview of what replaced flet in cl-lib and when to use each option.

  Emacs Lisp doesn’t have a built-in way to define local functions (the way let defines local variables), so cl-lib provides several macros for this. If you’ve ever been confused by cl-flet, cl-labels, and cl-letf – you’re not alone. The naming doesn’t make the distinctions obvious, and the documentation is a bit dry. Let’s try to fix that.

  Live Regexp Feedback with minibuffer-regexp-mode

  This is the third article in a small series inspired by my recent cleanup of Prelude and my personal Emacs configuration, following the ones on repeat-mode and read-extended-command-predicate. I’ve been going through the Emacs 28-30 changelogs for features I had ignored so far, and this one from Emacs 30 immediately caught my eye.

  Writing Emacs regexps has always been a bit of a dark art. Between the double-escaped backslashes and the various group syntaxes (\(...\), \(?:...\), \(?N:...\)), it’s easy to lose track of what you’re actually matching. You type something into query-replace-regexp, press RET, and hope for the best.

  Emacs 30 added minibuffer-regexp-mode, a minor mode that gives you live visual feedback as you compose a regexp in the minibuffer:

  (minibuffer-regexp-mode 1)

  Declutter M-x with read-extended-command-predicate

  This is another article inspired by my recent cleanup of Prelude and my personal Emacs config, following the one on repeat-mode. I’ve been going through the Emacs 28-30 changelogs looking for features I had overlooked, and this small one from Emacs 28 turned out to be a real gem.

  Ever noticed how M-x shows you every command, including ones that make no sense in your current buffer? Org commands while editing Ruby, Magit commands in a shell buffer, that sort of thing. It’s not a huge deal if you know what you’re looking for, but it adds noise to the candidate list – especially if you’re using a completion framework like Vertico or Ivy that shows everything at a glance.

  Emacs 28 added a simple way to fix this:

  (setq read-extended-command-predicate
        #'command-completion-default-include-p)
