envVar
envVar(variableName: String): String | Null
Returns an environment variable with the specified name or null
if the
environment variable is not defined.
Example
This example returns a Mac command console (SHELL
) path and returns null
on FAKE_ENV_VAR
(an undefined environment variable). SHELL
is one of the
standard Mac environment variables. Also notice that the import
command
enables you to call the function without prepending the module name to it.
