Is there a way go get to the server directory?

Is there a way to point to the directory that middleman uses for the server?

I would love to use middleman for my google chrome extension because I don’t like the way how https://github.com/yeoman/generator-chrome-extension does it.

The problem is that I have to point to the directory of the extension. I don’t want to always create a new build when I changed a file. Is there any way to gain the data that the middleman server command uses?

There is no server directory; the server sends pages directly to the web browser without saving them first.

I use guard-middleman to automatically build Chrome extensions into a tmpfs.
