Golang Git Build Vars

This is a quick demo of how to set information about your current git repository and build time as variables within your Go binary.

How it works

1. Gather information and set -ldflags during build in the Makefile
2. Define variables in your Go code that will be set during build

Variables

This example sets 3 variables:

1. Timestamp of when the build happens
2. The current git commit hash, including a ✗- prefix if the working directory is dirty
3. The current git branch

Run & example output

$ make
$ bin/vars
