My first play around with go, so I converted my latest_blame.py to go

latest_blame.go

// Simply run this executable with the file url inside github and it will find the most recent blame on the file
// Env:
// docker run -it golang:1.8
// Install:
// mkdir -p $GOPATH/src/github.com/user/latest_blame
// curl https://gist.githubusercontent.com/ghandic/dcfd6ac55cdc1a20e1bd12f3e7429f88/raw/latest_blame.go > $GOPATH/src/github.com/user/latest_blame/latest_blame.go
// go get github.com/anaskhan96/soup
// go install github.com/user/latest_blame
// Use:
// latest_blame --url https://github.com/ghandic/confluenceapi/blob/master/README.md
package main

}


func git_url_to_blame(git_url string) string {
