I’m currently writing a plugin for comprehensive C++ support using libclang. It has successfully replaced using Eclipse for about half a year now and I’m really happy to use Sublime for my daily work.
There’s just one catch: My plugin needs to get a list of all files in the current project. As far as I know, there is no API to do that. So I went ahead and wrote a function to walk the project directory myself using the file_include_patterns and file_exclude_patterns in the project settings. While this gives results that are close enough to what Sublime seems to be doing internally, it is awfully slow.
This is mainly because walking directories on Linux is generally slow in Python 3.3. So the startup time of my plugin is in orders of ~10 seconds for the project I’m working on which is just not what Sublime usually feels like.
I’d really like to have an API call that just returns a list of all file paths contained in the project. It’s information that Sublime has anyway so it should be fairly easy to expose. My only other option is to hack a newer version of Python into Sublime (AFAIK Python 3.4 contains a much faster implementation), but I really don’t want to go down that route!
