dotenv

func Load ¶

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 ¶

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 ¶

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 forcefully set all vars.

func Parse ¶

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

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

func Read ¶

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 ¶

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 UnmarshalBytes ¶

func UnmarshalBytes(src []byte) (map[string]string, error)

UnmarshalBytes parses env file from byte slice of chars, returning a map of keys and values.
