scripts-to-rule-them-all-go

Inspired from the 2015 repo for "Scripts to Rule Them All", this applies that same concept but with using a more modern toolchain like Go and Mage. Mage provides a Go based task runner that can replace makefiles, custom bash/python/powershell scripts, and instead provide a cross-platform common set of commands to run a project.

2022-03 🚧 WIP - Bringing in a few more examples. It's ready to use for basics though!

Why Mage

• Mage is cross-platform.
• Mage is Go. Go is fun. Go helps write really robust safe code with the error handling.
• Easy to plug-in to CI since Mage is just Go.

Why This Template?

This project is a template to help bootstrap a new project with a few things that normally result in more setup work. I've tended to standardize on a few key things.

• If it's complicated and I do periodically, wrap up the bash script commands in Go instead if it's only a few minutes of work.
• If I can, I'll use a package, but for things that are more complicated (like Kubernetes), start with just wrapping up kubectl commands and go from there.

Normal tasks:

Included & Prebaked

• Aqua: install project tooling with aqua and run aqua install to get tools setup.
• init: All projects bootstrap from this. It runs go mod tidy, go installs, and is extended for any other tools as well. For example, I'll add asdf:install to the init task and let it also ensure all apps I want are setup.
• devcontainer:build: Locally run the steps to grab the image and build a local containerized devcontainer to work in.

👉 Checkout magetools

I've been steadily baking automation tasks that are tested and reusable in there. Most of the tasks self-setup any tooling as well.

Custom

• publish: Focused on CI based publishing with a tool like goreleaser or ko.
• bump: Semantic versions
• doctor: Anytime a setup/problem in the project is experienced I try to add a diagnostic check on versions of apps, env vars, and other things and return this as a pass/fail or info table to summarize in a very clean way. This uses pterm.

Example Output

Running mage in a brand new project.

Template

You can use this as a template to get started with a project ready to run using Mage.

Setup

• Multiple options to install on Mage - Docs
• Additional options:

Using Go (won't have version info embedded)

go install github.com/magefile/mage@latest

Note

Optional: maintain //go:build mage to avoid impacting test coverage reports.

I've added this to the tags for language server build to recognize so you can use code completion.
