Dotenv

Golang version of Dotenv

Introduction

I wanted to use dotenv without being tied to Ruby, and there were a couple of behaviors I wanted to modify/remove.

Compile

Local

go get github.com/mattn/go-shellwords
go build

Example

## File w/ vars:
$ cat .env
FOO=bar

## Current env doesn't contain $FOO
$ env | grep FOO

## Default command is `env`
$ dotenv .env | grep FOO
FOO=bar

## To prevent .env-file "detection", start the command after double dash
$ dotenv -- env | grep FOO
FOO=bar

## The whole point: vars are exported to the environment
$ dotenv -- sh -c 'echo FOO is $FOO'
FOO is bar

Features and TODOs

• Parse arguments as .env files until one fails
• Allow inline VAR=val arguments à la /usr/bin/env
• No shell "interpolation"
• Handle multiple kinds of input:
  • raw: VAR=val
  • shell: VAR="val" and VAR='val'
  • exported shell: e.g. export VAR='val'
• Handle multiline vars
• Add "filters" à la jq
  • base64: base64@VAR=encoded value
  • url: VAR@url=unescaped URL
• Better builds
  • go get-able
  • Ensure dependency is fetched for go get
  • Dockerize for easier build (no need for local go)
