func (DotEnv) Exec ¶

func (obj DotEnv) 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 (DotEnv) GetBool ¶

func (o DotEnv) GetBool(key string, defaultVal string, errMsgRequired string) bool

func (DotEnv) GetEnv ¶

func (obj DotEnv) GetEnv(key string) utils.UtilString

func (DotEnv) GetFloat ¶

func (o DotEnv) GetFloat(key string, defaultVal string, errMsgRequired string) float64

func (DotEnv) GetInt ¶

func (o DotEnv) GetInt(key string, defaultVal string, errMsgRequired string) int32

func (DotEnv) GetInt16 ¶

func (o DotEnv) GetInt16(key string, defaultVal string, errMsgRequired string) int16

func (DotEnv) GetInt64 ¶

func (o DotEnv) GetInt64(key string, defaultVal string, errMsgRequired string) int64

func (DotEnv) GetString ¶

func (o DotEnv) GetString(key string, defaultVal string, errMsgRequired string) string

func (DotEnv) GetStringArray ¶

func (o DotEnv) GetStringArray(key string, sep string, errMsgRequired string) []string

func (DotEnv) GetUint ¶

func (o DotEnv) GetUint(key string, defaultVal string, errMsgRequired string) uint32

func (DotEnv) GetUint16 ¶

func (o DotEnv) GetUint16(key string, defaultVal string, errMsgRequired string) uint16

func (DotEnv) GetUint64 ¶

func (o DotEnv) GetUint64(key string, defaultVal string, errMsgRequired string) uint64

func (DotEnv) Load ¶

func (obj DotEnv) 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 (DotEnv) Marshal ¶

func (obj DotEnv) 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 (DotEnv) Overload ¶

func (obj DotEnv) 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 (DotEnv) Parse ¶

func (obj DotEnv) 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 (DotEnv) Read ¶

func (obj DotEnv) 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 (DotEnv) Unmarshal ¶

func (obj DotEnv) 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 (DotEnv) Write ¶

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

Write serializes the given environment and writes it to a file
