TIL that Emacs Lisp has had generators since 2016, and generators are a cool feature in any language in my opinion! In short, Emacs has the generator.el package as it’s part since version 25.1. The generators are implemented via transforming code and act like iterators, even most of the functions are called iter-something.
I’ve published two new packages for Emacs: - region-bindings.el and common-lisp-modes.el. Both are quite small and were a part of my configuration for a long time, but after small refactoring of my init.el I’ve decided to extract them. The first one, region-bindings is a from-scratch re-implementation of region-bindings-mode.
Another post in the not-so-series about Emacs configuration. Today I will describe my configuration for managing the compilation-error-regexp-alist variable in a way that is meaningful for the current project I’m working on. Some time ago I faced a problem that the compilation-error-regexp-alist variable contains far too many entries for different languages by default.
In Emacs version 28 Emacs developers introduced so-called read symbol shorthands. If you’re interested in the rationale, feel free to search the Emacs developer mailing list for the discussion. However, it does seem that not everyone likes the idea of shorthands as a substitution for namespaces (or packages, if you’re coming from Common Lisp).
Or “when you don’t have topics to write about, write about how you do your writing”. Ahem. I like my blog workflow, it makes me want to return to writing more often, and because of this, I capture way more thoughts than I would usually do if I didn’t have a blog.

Today I would like to talk about three separate tools, and how we can combine them with the power of Emacs.

I use Emacs mainly for programming, but I also write a lot of non-code in it, either for this blog, documentation for my projects, or just when I take notes. And I do it with a git-friendly style of formatting with a single sentence per line.
After publishing the last post I thought why won’t I post such things here occasionally? I have a few pieces of Emacs Lisp in my configuration that I wrote for myself some time ago to fix some annoyances or improve a certain workflow.
I was going through my git commit history in my public dotfiles repository and noticed that prior to using straight.el I’ve, like many, used an inbuilt solution for managing packages, called package.el. However, there was one thing that bothered me, and one of the reasons that made me think about switching to straight was the fact, that a lot of times when I wanted to update or install packages, I couldn’t, due to an outdated package cache.
Not so long ago I’ve written about Paredit and its quirks. I’ve been happily using Smartparens ever since that post, but something still bugged me. I was constantly thinking about the fact that Smartparens has numerous quirks in various languages and some known bugs that are unlikely to be fixed in the foreseeable future, given that the main maintainer doesn’t have a lot of spare time.
