RuboCop’s motto has always been “The Ruby Linter that Serves and Protects”.1 Now, with the addition of a server mode in RuboCop 1.31 that motto is truer than ever! But first - a bit of background. Most people value speed and we’ve been on a decade-long journey…

I used to rely on M-h to mark the structural element in Emacs; in text buffers, that'd be the paragraph, in org buffers, that was the whole outline item (when the cursor was in the heading line, at least). ...

A fully fledged demo of overriding the colours of the Modus themes using the customisation options they provide.

My blog posts here usually have a line like: tags: [ swift, xcode, codesigning ] For tags I don't use a lot, I sometimes don't remember how to write them. So I do the only sane thing -- and go to my website's ...

Addressing an innocuous question about the Notmuch email client’s default behavior took me surprisingly deep into the bowels of the package code. When the normal customization methods didn’t help, I realized it might be a good opportunity to live-code a solution.…

Speed up your Clojure debuging with a YASnippet

This article shows how to use R code to generate randomised text files to test the Emacs Denote package.

In today's stream, we'll automate a particular task that I don't find very fun: editing YouTube video descriptions. We'll use Emacs Lisp to interact with the YouTube Data API to pull down a video's description, edit it in a buffer, and then save the description…

I’ve long thought it was a little funny that Emacs doesn’t provide an
easy way to run a shell command on the current file. It turns out it
does, but it’s not as obvious as you might expect.

Today I saw a clever bit of Clojure code involving clojure.string/replace, that reminded me how powerful the Clojure standard library is. I guess pretty much everyone knows that replace is normally used to replace some part of a string using a regular expression…

Many programming languages have a function for combining the elements of multiple collections (e.g. arrays or lists) together. Typically this function is named zip. Clojure doesn’t have a zip function in the standard library, which leads many newcomers to…
