Hi. I'm trying your package and had a lot of trouble to get it to work right until I found out that variables inside quotes is ignored. The regex that catches variables inside files is not catching when using quotes.
This is ignored by the regex:
while this is not:
In this case the quotes is not needed but I write quotes without even thinking about it since I work in a filesystem with many folders with spaces in them.
It's not a big deal since it's possible to get it to work without the quotes but pretty frustrating until you know whats going on. If you don't improve the regex maybe you could include a note about this in the documentation.
Thanks anyway for a very useful package!
