Some environment variable
Environment storage and variable expander.
localEnvironment :: Functor m => ExpanderT m a -> m a Source
Run this function inside a blank environment.
forkEnvironment :: (Functor m, Monad m, MonadIO m) => ExpanderT m a -> m a Source
Run this function in a locally modifiable, but not exported environment
expandVars :: (Monad m, Functor m, ChExpanderEnv m) => String -> m String Source
