Installation

Git submodules

git submodule add  https://github.com/Eggflaw/lune-dotenv.git

Usage

Create a .env file into the root directory of your project.

OPENCLOUD_KEY=OPENCLOUDKEYHERE
SECRETS="SECRETS"

You can now load the .env file with lune-dotenv

local process = require("@lune/process")
local dotenv = require("Packages/lune-dotenv") -- Assuming you added lune-dotenv into Packages/

dotenv:load() -- Must come before accessing process.env
print(process.env.OPENCLOUD_KEY) -- Remove after you confirmed it's working

API

dotenv:load(overwrite: boolean?, path: string?)

Loads a .env file and add it into process.env

By default, load will find a .env file in the current working directory

If there is an environment variable with the same key name, lune-dotenv will not overwrite it.
Set overwrite to true to avoid this.

dotenv:load(false)
print(process.env.HOME) -- "/home/yourname"

--============--

dotenv:load(true)
print(process.env.HOME) -- "NEWHOME"

You can give load a custom path instead of finding a .env in the current directory

dotenv:load(false, "tests/envs/path.env")
print(process.env.CUSTOM_PATH)

dotenv:parse(str: string): { [string?]: string? }

Parse .env content and convert it into a table.
Use this if you don't want to load .env into process.env

local content = fs.readFile(".env")

local env = dotenv:parse(content)
print(env)
