Is there a way to programmatically download a single file from a remote Mercurial repository, in Java? I have asked a very similar question regarding git ; now I'm hoping I can do something similar with mercurial as well. I prefer a solution which uses as little bandwidth as possible, preferably only downloading that single file. I do not need to browse the repository, I already have the file's path. I am not concerned with the history of the file, I only want its latest version. A solution that only prints the file to the output is great as well, of course - it doesn't really have to save the file to disk, I can do that myself. I prefer a solution which does not depend on other applications (e.g. an installation of a mercurial client on the machine). A Java library which contains a mercurial client implementation itself would be optimal. However, I will happily invoke hg if there's no other way. From what I understand about how Mercurial works - allowing working only against local repositories - this could prove to be problematic; but as I was able to do this with the similar Git SCM I'm hoping there's a solution for Mercurial as well.
