getEnv package:base-compat

Computation getEnv var returns the value of the environment variable var. For the inverse, the setEnv function can be used. This computation may fail with:

• isDoesNotExistError if the environment variable does not exist.

getEnvironment retrieves the entire environment as a list of (key,value) pairs. If an environment entry does not contain an '=' character, the key is the whole entry and the value is the empty string.
