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.

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.
I’ve been into clojure.core.async lately, and I like the overall design of this library - it’s simple and easy to understand. However, at work, we use manifold in our projects, mainly because it is supported by the aleph server, which was chosen because it can asynchronously read data coming from the client.
This is a follow-up to my previous post regarding the bug in the clojure.core.async/pipeline-async function.
As I’ve mentioned at the end of that post, I’ve submitted a patch to Ask Clojure that should fix the off by two error for the asynchronous pipeline.
Quite recently I’ve been working on my asynchronous programming library for Fennel, and fiddling with clojure.core.async at the same time for my other project. I’ve found an interesting function, called pipeline-async, which seemed to be a good fit for my task. Here’s the documentation for this function:
When it comes to software I prefer things that are simple and small, even though I’m using Emacs. This is mainly the reason why my favorite languages are Clojure and Fennel. However, it doesn’t end on programming languages themselves, I like small tools in general.
Today I would like to talk about three separate tools, and how we can combine them with the power of Emacs.
Recently I’ve stumped upon a Reddit thread about defining a function that you can call a limited amount of times in Rust, with compile-time check, and I wondered if I can make the same thing in Clojure.
Some time ago I ported most of Clojure’s core namespace to Fennel and made it into a library called fennel-cljlib. This was my first library for Fennel, so it wasn’t really great in terms of how it was implemented. While it was making Fennel more like Clojure syntax-wise, which I like, it wasn’t following Clojure’s semantics that well.
I often hear this phrase: “programmers are counting from zero”. Not so long ago I actually decided to check if it is true and asked some programmers I know to count to ten out loud.
None of them counted from zero.
Well, this phrase is usually brought up when discussing various programming languages, which share the common idiom - zero-based array indexing.
