If it was a SQLite3 wrapper for Haiku, that would allow a lot of software to use BeFS that otherwise wouldn’t. One example is that Draken visual language editor I was hoping to adapt to Haiku which uses SQLite as its only file format internally.
Speaking of which, the Lua 5.2 backend I thought of adapting works already and several Lua versions are in HaikuPorts. I’d prefer to use the C++ backend for the editor itself but it currently uses Qt. Also, Luau wouldn’t be a hard port but I need to get familiar with Drakon first and foremost. Maybe I’ll just use the generators and rewrite the editor.
