linecfg - a single-line configuration format

linecfg is a single-line configuration format. It solves the case where you want to pass some configuration to a process in a single environment variable. It’s better than to cram everything into a URL.

This repo provides the canonical implementation in go.

How does it look like?

The linecfg is essentially key=value pairs separated by a single space:

host=localhost port=400 timeout=5s

It should be easy enough to implement in a couple of lines in any language.

For more details on why this is the right thing to do look at the full spec: SPEC.adoc

Go example

example/main.go

package main

import (
       "log"

       "github.com/pusher/linecfg-go"
)

type Config struct {
       Host     string
       SomePort int `linecfg:"port"`
}

func main() {
       c := new(Config)

       err := linecfg.Getenv("MY_CFG", c)
       if err != nil {
               log.Fatalln(err)
       }

       log.Println("host", c.Host)
       log.Println("port", c.SomePort)
}

$ MY_CFG="host=localhost port=443" go run example/main.go
2016/09/13 16:37:15 host localhost
2016/09/13 16:37:15 port 443
