Bump

Thanks for letting us know this is still desired!

Unfortunately, while I wish I had a more satisfying response, I'm sorry to say that this might remain outstanding for some time :( Rouge depends for its feature development on contributions from its community. If you'd like to see a syntax supported, the best thing to do is submit a PR with your new lexer.

When I became a maintainer, I wrote a guide on lexer development that might be of help. We have quite a backlog of existing PRs but we give newer ones priority so anything you submit will go to the top of the pile.

I would be interested in this feature too.

Added a basic lexer for SSH config in #1543.
