Flow-typed JavaScript works well with our existing JavaScript support. Post an issue if you have any issues when trying it out: https://github.com/sourcegraph/issues/issues. For Ruby, we haven't investigated the situation in a few months. Last time, we checked out https://github.com/mtsmfm/language_server-ruby but it was not far enough along. We maintain a table of language servers at http://langserver.org/, and once they have support for hovers, definitions, and references, we begin to plan to integrate them. We'll be releasing a roadmap for Sourcegraph language support soon with a lot more docs for how to integrate existing language servers, too.

Sorry to hear that it didn't work out of the box for your repositories. I've filed the non-Unicode text issue here: https://github.com/sourcegraph/issues/issues/32 We're actively working on improving the performance of diff search, but I would expect other types of queries to complete quickly. Would you mind sharing more about the size / characteristics of your repositories? Feel free to email me at beyang@sourcegraph.com if a private channel is better.
