package godotenv

import "github.com/joho/godotenv"

Package godotenv is a go port of the ruby dotenv library (https://github.com/bkeepers/dotenv)

Examples/readme can be found on the github page at https://github.com/joho/godotenv

The TL;DR is that you make a .env file that looks something like

SOME_ENV_VAR=somevalue

and then in your go code you can call

godotenv.Load()

and all the env vars declared in .env will be available through os.Getenv("SOME_ENV_VAR")

Package Files

godotenv.go

func Exec Uses

func Exec(filenames []string, cmd string, cmdArgs []string) error

Exec loads env vars from the specified filenames (empty map falls back to default) then executes the cmd specified.

Simply hooks up os.Stdin/err/out to the command and calls Run()

If you want more fine grained control over your command it's recommended that you use `Load()` or `Read()` and the `os/exec` package yourself.

func Load Uses

func Load(filenames ...string) (err error)

Load will read your env file(s) and load them into ENV for this process.

Call this function as close as possible to the start of your program (ideally in main)

If you call Load without any args it will default to loading .env in the current path

You can otherwise tell it which files to load (there can be more than one) like

godotenv.Load("fileone", "filetwo")

It's important to note that it WILL NOT OVERRIDE an env variable that already exists - consider the .env file to set dev vars or sensible defaults

func Marshal Uses

func Marshal(envMap map[string]string) (string, error)

Marshal outputs the given environment as a dotenv-formatted environment file. Each line is in the format: KEY="VALUE" where VALUE is backslash-escaped.

func Overload Uses

func Overload(filenames ...string) (err error)

Overload will read your env file(s) and load them into ENV for this process.

Call this function as close as possible to the start of your program (ideally in main)

If you call Overload without any args it will default to loading .env in the current path

You can otherwise tell it which files to load (there can be more than one) like

godotenv.Overload("fileone", "filetwo")

It's important to note this WILL OVERRIDE an env variable that already exists - consider the .env file to forcefilly set all vars.

func Parse Uses

func Parse(r io.Reader) (envMap map[string]string, err error)

Parse reads an env file from io.Reader, returning a map of keys and values.

func Read Uses

func Read(filenames ...string) (envMap map[string]string, err error)

Read all env (with same file loading semantics as Load) but return values as a map rather than automatically writing values into env

func Unmarshal Uses

func Unmarshal(str string) (envMap map[string]string, err error)

Unmarshal reads an env file from a string, returning a map of keys and values.

func Write Uses

func Write(envMap map[string]string, filename string) error

Write serializes the given environment and writes it to a file
