I’ve written about Clojure’s threading macros and their implementation in Elisp before [1, 2, 3, 4, 5]. I like them but almost always use the traditional composition of functions instead. That’s probably because being a mathematician it seems natural to me. Still, the threading macros are easier to read and understand.
Most people who care about such things know about Magnar Sveen’s implementation of these macros in his Dash library. They have the advantage of using the same names, ->, ->>, etc. as clojure. Of course, you have to install Dash to use them. That’s not much of a problem because so many packages use Dash that it’s probably already installed.
But what if you don’t want the dependency? It turns out that Elisp has the most important of these macros built in and has since at least Emacs 25. The first, thread-first corresponds to -> and the second, thread-last, corresponds to ->>. They live in the sub-x.el file if you want to check out there definition.
Ruslan Bekenev has a page that explains all this and even gives a short explanation of how to use the macros. If you’re interested in the threading macros, take a look at his post.
