chainlib

chainlib is a library of helper functions for writing utilities which pass state to other binaries using chain loading, a technique popularized by DJB.

Minimal example

package main

import (
	"time"

	"github.com/lwf/chainlib"
)

func realMain() (map[string]string, error) {
	return map[string]string{
		"time": time.Now().String(),
	}, nil
}

func main() {
	chainlib.Main("MYNAMESPACE", realMain)
}

# ./example /bin/sh -c 'echo $MYNAMESPACE_TIME'
