Nix Flakes and Direnv on Mac OSX (Catalina)

Development environment with Nix Flakes and Direnv

This document is targeted at those who seek to build reproducible dev environment across machines, OS, and time.

It maybe easier for remote teams to work together and not spending hours each person setting up asdf/pyenv/rbenv, LSP servers, linters, runtime/libs. Nix is probably the closest thing to Docker in terms of development environment.

Flake is used here because it provides hermetic build, with absolutely no reliance on system environment (be it Arch/Catalina/Mojave). Also it freezes dependencies in flake.lock so builds are reproducible.

This gist provides the setup to develop Java/Clojure/Python applications on Nix. But it can be easily adapted to ruby, nodejs, haskell.

cljs command

If you wan't a cljs that acts like clj, but for ClojureScript, there are a few minor changes you can make:

First, add the following entry to ~/.clojure/deps.edn under the :deps key:

org.clojure/clojurescript {:mvn/version "1.10.439"}

Then make copies of clj and clojure named cljs and clojurescript, and put those copies on your path.

Update

Just use https://github.com/ripeworks/iro which gets the challenge below right!

Mac Color Picking Done Right

Picking a Color on Mac is hard. Mainly due to the fact that several applications floating around the web ( AppStore and independant ), grab the color "incorrectly".

Why incorrectly?
