So I’ve been playing with Zig lately, and one of the fun caveats of using a programming language thats in rapid development is that you need to update a lot, often using the latest nightly build due to some bugfix or new experimental feature. It makes it very entertaining to use and one of these days I should write down my thoughts in general on Zig… but I digress.
I needed a quick way to make sure that I can update both Zig and zls, the Zig language server. There is a tool out there called zigup but it doesn’t work well cross platform and I jump between Arch Linux, macOS, and OpenBSD regularly.
This zsh script is what I use on Linux and macOS to keep Zig updated, and I’ll update it to work on OpenBSD’s ksh when I have time (ha yeah right). It requires curl, wget, and jq. I keep all my local executables in $HOME/.local/bin, so modify that to fit your environment as needed
#!/usr/bin/env zsh
set -e

echo "No folder starting with 'zig' found."
