script

A super package to provide syntactic sugars for writing scripts in Golang.

Use with Gorun

1. Go get to obtain the gorun binary: go get gorun
2. Create an empty dir and initialize a new go module, mkdir build, cd build, go mod init build
3. Inside the build dir, call go get -u github.com/chanwit/script@master to add it as a dependency
4. Create build.go, as followed:

/// 2>/dev/null ; gorun "$0" "$@" ; exit $?

// go.mod >>>
// module build
// go 1.15
// require (
//   github.com/chanwit/script v0.0.0-20210123134408-7360ef9587f5
// )
// <<< go.mod

package main

import (
	. "github.com/chanwit/script"
)

func main() {
	out := Var()
	System("echo hello").To(out)
	Printf("we are echoing: %s\n", out.String())

	list := Var()
	Exec("docker", "ps").To(list)
	Print(list.String())
}

then you can chmod +x build.go and simply run it with ./build.go
