First off, thanks for this library! It is working great in my testing so far!

Is it possible to have multi-line env variables? Where there is a literal newline in the file? Although I suppose it isn't truly needed because you can use \n to encode it.

Good idea! But how would you encode it in the file, besides \n?

FOO="val
continues
maybe"

# Or heredoc (cut out first and last linebreaks)?

FOO="""
val
continues
maybe
"""

That first option is exactly what I was thinking, and I think of the two it would be the better option because it would be a more general encoding. Using a heredoc feels a little too Elixir specific.

Here's another example:

FOO=val\
continues\
maybe

What I'm worried about is complicating the parser too much. Currently it's very simple since it can go line-by-line.

BTW heredocs are familiar to me from PHP. Maybe we should use that style. 😄

FOO=<<<val
continues
maybe
<<<FOO;

Triple quotes would be also how to do it in Python, so it doesn't feel too Elixir specific to me.
