This is effectively a port of dotenv, whose README explains it best:
Storing configuration in the environment is one of the tenets of a twelve-factor app. Anything that is likely to change between deployment environments–such as resource handles for databases or credentials for external services–should be extracted from the code into environment variables. But it is not always practical to set environment variables on development machines or continuous integration servers where multiple projects are run. dotenv loads variables from a .env file into ENV when the environment is bootstrapped.

This library exposes functions for doing just that.
Synopsis
- loadEnv :: IO ()
- loadEnvFrom :: FilePath -> IO ()
- loadEnvFromAbsolute :: FilePath -> IO ()
Documentation
loadEnvFrom
".env"
loadEnvFrom :: FilePath -> IO () Source #
Parse the given file and set variables in the process's environment
Variables can be declared in the following form:
FOO=bar FOO="bar" FOO='bar'
Declarations may optionally be preceded by "export "
, which will be
ignored. Trailing whitespace is ignored. Quotes inside quoted values or
spaces in unquoted values must be escaped with a backlash. Invalid lines are
silently ignored.
NOTE: If the file-name is relative, the directory tree will be traversed
up to /
looking for the file in each parent. Use
to avoid this.loadEnvFromAbsolute
loadEnvFromAbsolute :: FilePath -> IO () Source #
, but don't traverse up the directory treeloadEnvFrom
