package envy makes working with ENV variables in Go trivial.
* Get ENV variables with default values. * Set ENV variables safely without affecting the underlying system. * Temporarily change ENV vars; useful for testing. * Map all of the key/values in the ENV. * Loads .env files (by using [godotenv](https://github.com/joho/godotenv/)) * More!
const GO111MODULE = "GO111MODULE"
GO111MODULE is ENV for turning mods on/off
const Version = "v1.7.1"
CurrentModule will attempt to return the module name from `go.mod` if modules are enabled. If modules are not enabled it will fallback to using CurrentPackage instead.
CurrentPackage attempts to figure out the current package name from the PWD Use CurrentModule for a more accurate package name.
Get a value from the ENV. If it doesn't exist the default value will be returned.
GoPaths returns all possible GOPATHS that are set.
Load .env files. Files will be loaded in the same order that are received. Redefined vars will override previously existing values. IE: envy.Load(".env", "test_env/.env") will result in DIR=test_env If no arg passed, it will try to load a .env file.
Map all of the keys/values set in envy.
Mods returns true if module support is enabled, false otherwise See https://github.com/golang/go/wiki/Modules#how-to-install-and-activate-module-support for details
Get a value from the ENV. If it doesn't exist an error will be returned
MustSet the value into the underlying ENV, as well as envy. This may return an error if there is a problem setting the underlying ENV value.
Reload the ENV variables. Useful if an external ENV manager has been used
Set a value into the ENV. This is NOT permanent. It will only affect values accessed through envy.
func Temp(f func())
Temp makes a copy of the values and allows operation on those values temporarily during the run of the function. At the end of the function run the copy is discarded and the original values are replaced. This is useful for testing. Warning: This function is NOT safe to use from a goroutine or from code which may access any Get or Set function from a goroutine
