Here is a nice sample using segdsp as a library: https://github.com/racerxdl/segdsp-sample
SegDSP is pretty straightforward to run if you know what you want to capture. It accepts both Environment Variables (suitable for docker containers) or just normal command line arguments.

Inside the project repository create the following file:
touch .git/hooks/pre-commit
And paste this code inside it:
#!/bin/bash
echo "Formatting code"
go fmt ./...
exit 0
And give execute permission:
chmod +x .git/hooks/pre-commit
