gotip

Warning

This repository is experimental.

Purpose

Sometimes you want to try out a new feature of Go, or make sure that your code works with the latest version of Go. To do so, you can use the gotip command, and execute gotip download to download and build Go from the development tree.

However, this may require some time (3+ minutes in Ubuntu runners, 6+ minutes in Windows runners), so the purpose of this repository is to have pre-compiled binaries of the latest version of Go, so you can download them and use them in your pipelines, which usually takes few seconds (less than a minute), without having to wait for the compilation process

By default, it builds a new release every 6 hours, but you can also trigger a new build manually.

Usage
