Overview ¶
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 avaiable through os.Getenv("SOME_ENV_VAR")

Functions ¶
func Exec ¶
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 ¶
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 Overload ¶
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.
