gofmtrlx: Relaxed gofmt

This is a fork of gofmt.

This project is being rebased continuously on original gofmt (as long as I’m using gofmtrlx).

What is a problem?

gofmt can’t format a code which contains syntax error. For example,

package main
func main() {
    s := []int{
        1,
        2,
        3
    }
}

This code can’t be formatted because there is no trailing comma at line 6.

Actually, Go’s parser can parse this without bad AST node. So gofmt can format the code with fixing syntax error.

gofmtrlx ignores syntax error if there is no bad node in AST. In above code, gofmtrlx can fill up trailing comma
on formatting it.

go get -u github.com/rhysd/gofmtrlx

Usage is the same as gofmt command.

All codes are licensed the same license as original gofmt.
