go-build-bash

A bash script that emulates go build.

The goal of this project is to help Go users understand what to do to build a package.

Some advantages of go-build-bash over the official go build include:

• The script is written in bash, making it easier to understand for those unfamiliar with Go.
• The build log is carefully designed, providing a clear view of the process. You can see an example log of building "hello world" program here.

It can build large modules like kubectl , uber-go/zap, spf13/cobra, golang/protobuf etc.

Host machine

• Bash 5.1 or later
• go version 1.20

Cross compilation supported

4 combinations of cross OS compilation are supported:

• darwin => darwin
