go-printf-func-name

The Go linter go-printf-func-name checks that printf-like functions are named with f at the end.

Example

myLog should be named myLogf by Go convention:

package main

import "log"

func myLog(format string, args ...interface{}) {
	const prefix = "[my] "
	log.Printf(prefix + format, args...)
}

$ go vet -vettool=$(which go-printf-func-name) ./...
./main.go:5:1: printf-like formatting function 'myLog' should be named 'myLogf'
