My Hawt set of Go Packages

Install with:

go get github.com/chirino/hawtgo

Pacakge: sh

The sh package makes executing processes from go almost as easy as using a shell.

See the following example that takes care of splitting up the command arguments and doing variable replacement:

 sh.New().Line(`cp "${HOME}/my file.txt" /tmp/target.txt`).MustExec()

sh will can run command string like the ones you would enter into your shell.

The sh.New() function give you back a new immutable builder object. You can safely reuse it for multiple command invocations.

var mysh = sh.New().
    CommandLog(os.Stdout).
    CommandLogPrefix("> ").
    Env(map[string]string{
        "CGO_ENABLED":     "0",
        "GOOS":            "linux",
        "GOARCH":          "amd64",
    }).
    Dir("./target")
    
func BuildExecutable() {
    mysh.Line(`go build -o "my app" github.com/chirino/cmd/myapp`).MustExec()
    mysh.Line(`go build -o otherapp github.com/chirino/cmd/otherapp`).MustExec()
}
