Clojure Development Setup

TLDR to copy and paste a clojure dev setup on MacOS.

Install packages

brew install openjdk rlwrap clojure leiningen borkdude/brew/babashka babashka/brew/neil visual-studio-code

git config --global --list

Clear problem statement: steps you took, what you expected, what actually happened.

Efficient hypothesis: bisect the problem.

The docker images can all be run/built similar to the following.

Setup the variables per image.

GitHub Example

Clojure CLI tools (with deps.edn) allow for a built in way to create projects.

brew install openjdk clojure rlwrap

A cheatsheet inspired by the book "Clojure for the Brave and True".

Examples:

	##-- Aliases --##
	alias ll='ls -l'
	alias k='kubectl'
	alias ke='kubectl exec -it'
	alias kc='kubectx'
	alias kn='kubens'

	##-- Completions --##
	# bash-completion@2 (installed via brew install bash-completion@2)
	[[ -r "/opt/homebrew/etc/profile.d/bash_completion.sh" ]] && . "/opt/homebrew/etc/profile.d/bash_completion.sh"

	.PHONY: build test deploy

	##-- Environment Variables --#

	# Image and container registry
	IMAGE_NAME := my-image-name
	IMAGE_PATH := mygroup/myproject
	REGISTRY := registry-url:port
	IMAGE := $(REGISTRY)/$(IMAGE_PATH)/$(IMAGE_NAME)

	;; Returns a function with retries.
	;; retries: num of retries
	;; delay: delay between retries in milliseconds
	;; f: function to apply
	;; ef: error function, determines if f should be retried
	;; f and ef should not throw Exceptions

	(defn with-retry
	[retries delay f ef]
	(fn [& args]
