1. Overview Purpose: Allow a host application (e.g., editor, IDE, media player, game engine) to open external files via a plugin system. The plugin registers a custom file open handler to intercept or extend the application’s native file opening behavior.
Define standard return codes:
# Fallback to native open return native_open(filepath) # plugin.py from hostapi import FileOpenHandler class CustomHandler(FileOpenHandler): def can_handle(self, path): return path.endswith('.encrypted') plugin file open
// Cleanup void (*on_close)(void* context); FileOpenPluginAPI; "id": "com.example.custom-opener", "version": "1.0.0", "hooks": "file-open": "extensions": [".xyz", ".custom"], "priority": 10, "async": true, "handler": "handlers/file_open.js" "hooks": "file-open": "extensions": [".xyz"
