This release includes changes to the exec package that will require changes
to client code.
The exec package has been re-designed with a more convenient and succinct API.
This code:
args := []string{“diff”, “-u”, “file1.txt”, “file2.txt”}
p, err := exec.Run(“/usr/bin/diff”, args, os.Environ(), "",
exec.DevNull, exec.Pipe, exec.DevNull)
if err != nil {
return nil, err
}
var buf bytes.Buffer
io.Copy(&buf, p.Stdout)
w, err := p.Wait(0)
p.Close()
if err != nil {
return nil, err
}
return buf.Bytes(), err
can be rewritten as:
return exec.Command(“diff”, “-u”, “file1.txt”, “file2.txt”).Output()
See the exec package documentation for the details ("godoc exec").
By setting the GOPATH environment variable you can use goinstall to build and
install your own code and external libraries outside of the Go tree (and avoid
writing Makefiles).
See the goinstall command documentation for the details ("godoc goinstall").
