Mage

Mage is a make-like build tool using Go. You write plain-old go functions, and Mage automatically uses them as Makefile-like runnable targets.

When to Use

Creating build scripts for Go projects.
Automating tasks (install, build, clean, release).
Managing dependencies between tasks.

Core Concepts

1. Magefiles

Any Go file with
```
//go:build mage
```
(or
```
+build mage
```
for older Go).
Usually named
```
magefile.go
```
or placed in
```
magefiles/
```
directory.
```
package main
```
.

2. Targets

Exported functions with specific signatures:
```
func Target()
```
```
func Target() error
```
```
func Target(ctx context.Context) error
```
First sentence of doc comment is the short description (
```
mage -l
```
).

3. Dependencies

Use
```
mg.Deps(Func)
```
to declare dependencies.
Dependencies run exactly once per execution.
```
mg.Deps
```
runs in parallel;
```
mg.SerialDeps
```
runs serially.

Quick Start

To create a new magefile:

mage -init

github.com/magefile/mage/sh

// ...
