mrosset/go-binfmt

go-binfmt registers Go language .go files with binfmt which allows you to run Go files directly.

Install go-binfmt.

$ go get github.com/str1ngs/go-binfmt

To use go-binfmt first register it with binfmt.

$ sudo $GOPATH/bin/go-binfmt -register

To run a go file give it executable permissions, and then run it.

$ chmod +x main.go
$ ./main.go

go-binfmt's Issues

Could it keep its working directory when executable run?

I mean, for /tmp/foo.go

cd /home
/tmp/foo.go # try to show current directory will show '/home'?

Won't build

$ go get github.com/str1ngs/go-binfmt

util no longer exposes checkFatal.

default archlinux can not run

kernel needs binfmt support and mounted to /proc/sys/fs/binfmt_misc

Could you describe it on your reame about what are options should turn on kernel and how.

can not support input os.Args() parameters

$./t.go a b c 
[/tmp/go-build466606284/_/t/_obj/a.out]  
# should be [/tmp/go-build466606284/_/t/_obj/a.out]  b c
# or better [original_path/t.go]  b c

$cat t.go                                 
package main

import "os"
import "fmt"

func main() {
    fmt.Println(os.Args)
}

get not build on go version weekly.2012-03-13

go get github.com/str1ngs/go-binfmt

github.com/str1ngs/go-binfmt

str1ngs/go-binfmt/main.go:71: undefined: util.FileExists
str1ngs/go-binfmt/main.go:91: undefined: util.FileExists

Could it keep its os.Args[0]

eg.
/tmp/foo.go
chmod +x /tmp/foo.go

/tmp/foo.go # show its os.Args[0] will show /tmp/foo.go ?
