A little Clojure configuration reader

This is a handy bit of code I've written more than once. I thought I'd throw it in here so I can refer back to it later. Basically, it lets you read a config file to produce a Clojure map. The config files themselves can contain one or more forms, each of which can be either a map or a list. Maps are simply merged. Lists correspond to invocations of extension points, which in turn produces a map, which is merged along with everything else.

An Example

Consider the following files:

names.edn

Emacs Config

;;

This is a ‘minimum viable config’ built for the purpose of literate programming with Clojure / Clojurescript. It uses MELPA to download and install a few packages that I consider necessary for a good Clojure dev. experience, though that’s of course only my opinion. I use CIDER, a robust and popular REPL tool. It could arguably be substituted for inf-clojure, but I haven’t tried that myself.

This config does assume that you already have emacs installed and that you have at least a cursory understanding of how to navigate and use it. Or, at the very least know a few keywords to search as you try learn things. Emacs can be a daunting tool (I don’t even know most of it myself yet, honestly), but you can do the most critical things without too much difficulty and a bit of patience.

; Ruby has an awesome feature -- string interpolation. Read about it on the internet.
; On the other hand, Clojure only has cumbersome Java string formatting, which can not be
; used without pain after you've tried Ruby.

; So here's this simple macro that basically allows you to do most things you could do
; with Ruby string interpolation in Clojure.
