Our mailing list blocked a message from CodeLobster. They would like our community to know about their product. Here's my summary (haven't tried it): http://www.codelobsteride.com/ - targets "web languages" -- PHP, HTML, CSS, JavaScript - seems to be a free level and then a paid level - there are packages for at least Ubuntu, Fedora, and debian - it seems to know about a lot of frameworks (perhaps only for the paid level). I don't see a claim that it is open source.
