A half-hour to learn Zig

This is inspired by https://fasterthanli.me/blog/2020/a-half-hour-to-learn-rust/

Basics

the command zig run my_code.zig will compile and immediately run your Zig program. Each of these cells contains a zig program that you can try to run (some of them contain compile-time errors that you can comment out to play with)

Vim + Eclim + Scala

WARNING! Do not install anything from update sites before installing Eclim! This is because Eclim determines available project natures (android, scala, etc) by trying to discover them at install time. If they are installed on a per-user basis, it won't find them. If you're installing Eclim for use with an existing Eclipse install

You're also better off not to install any plugins via your package manager. Eclim will give you the option to install plugins associated with each project nature from its install wizard.

Install Eclipse Luna. On Arch Linux, it's available in extra.

pacman -Sy eclipse
