Help to start with a custom VFS plugin

We are trying to create a plugin for PyCharm to integrate with our proprietary platfrom which has a layed model to store source files in a database.

Can someone help to understand APIs involved here:

  1. I guess we need to implement a custom VFS. From samples I see it's still not clear what abstractions are involved. It looks most implementations  are readonly. How does IDE communicates saves to VFS?
  2. What is the best way to integrate our custom VFS in IDE given it's not such another additional protocol but the main root for source files?  I mean, by default when a new project is created, IDE asks for a location on disk for the root directory. Is it possible (and how) to register a custom protocol tied to our custom VFS, which can we used instead of a file path when a new project is created?


Any hints will be helpful?

Thanks a lot,
Dmitry

Hi Dmitry,

1. Writing to a custom VFS is performed through calls to VirtualFile.getOutputStream().

2. As far as I know this is not currently possible. You'll need to provide a custom implementation for a new project wizard, or (as an easier to implement but somewhat less nice to use option) an action that will move the contents of a project from the regular file system into your VFS and reconfigure the project accordingly.
