Double blind peer review when paper cites author's GitHub repo for code I and my coauthor wrote a paper and the project involved creating a (small) software library. Part of the novelty of the paper is the output of the code, which is a digital object not intended for by-hand manipulation. The code (open source) would ideally also be useful for others. One journal to which I was considering submitting this requires double-blind peer review, but the GitHub repo where the code is stored, referenced in the paper, identifies one of us simply by looking at the username in the url. We can of course obscure our identities in the paper as authors, but really need to cite the code repository. 

I've not had to do double blind review before, and so it's not clear what we should do. My coauthor is going to run into more problems of this sort as they continue research with a similar mix of code-and-paper as output.

Is there anything we can do, at least as a first attempt to soothe the journals worries?
Censor out the repo's name, and provide code to the referees as an auxiliary file.
