File system plugins

Those plugins provide methods to access files on various storages. For instance, ‘python’ plugin uses the python API to access local files (file://), so does the GIO implementation (openpaperwork-gtk). Memory plugin allow storing data in filesystem-like manner (memory://). Later other plugins could provide access to other storages (MariaDB, HTTP, etc).

The reference implementation is ‘python’.

A fake/mock implementation is provided for testing. It behaves in a way similar to the memory plugin.

Python-based implementation

In-Memory implementation

Provides support for URIs “memory://”. Those files are actually stored in memory. It is only useful for temporary files. It has been made as a plugin so it can easily be disabled on low-memory systems (will fall back on gio.fs –> real on-disk files).
