# Plugins

This folder is the primary home for bundled plugins and also the default search
path for drop-in plugins.

User-facing docs and CLI flows treat these integrations as plugins. Some Python
types and some stored config keys still use older `Provider` naming internally,
but that is a legacy implementation detail rather than the preferred public
term.

Preferred layout:
- Put each plugin in its own folder under `plugins/<name>/` with an `__init__.py`.
- Keep plugin-specific assets beside the code in that same folder.
- Single-file `.py` plugins are still supported, but package folders are the
  recommended plug-and-play format.

That means a plugin can ship as a drag-and-drop folder with extras such as:
- `cookies.txt`
- templates or fixture files
- helper modules
- small static assets

Built-in bundled plugins use the same layout as external plugins. Additional
drop-in plugin search paths are:
- `plugins/` in the repo root
- `plugins/` in the current working directory
- Any directory listed in `MM_PLUGIN_PATH`
- Any directory listed in `MEDEIA_PLUGIN_PATH`

Plugin rules:
- A plugin can be a single `.py` file or a package directory with `__init__.py`.
- Current plugin classes inherit from `PluginCore.base.Provider`.
- Give the plugin a stable name using `PLUGIN_NAME` or the class name.

Example skeleton:

```python
from PluginCore.base import Provider, SearchResult


class MyPlugin(Provider):
    PLUGIN_NAME = "myplugin"
    URL_DOMAINS = ("example.com",)

    def search(self, query, limit=50, filters=None, **kwargs):
        text = str(query or "").strip()
        if not text:
            return []
        return [
            SearchResult(
                table="myplugin",
                title=f"Result for {text}",
                path=f"https://example.com/{text}",
            )
        ]
```

Bundled walkthrough:

- Plugins can expose named config instances. The current stored config may still
  use legacy key paths such as `provider.<plugin>.<instance>`, and cmdlets target
  instances with `-instance <name>`.
- Use `.config plugins` in the CLI to browse configured plugin instances.
- The repo now includes a real FTP example plugin in [plugins/ftp/__init__.py](plugins/ftp/__init__.py).
- The walkthrough is in [docs/ftp_plugin_tutorial.md](docs/ftp_plugin_tutorial.md) and shows `search-file -plugin ftp -instance <name>`, folder drill-in via `@N`, file download routing, `@N | add-file -instance ...`, and `add-file -plugin ftp -instance <name>` uploads.
- The repo also includes an SCP example plugin in [plugins/scp/__init__.py](plugins/scp/__init__.py).
- The walkthrough is in [docs/scp_plugin_tutorial.md](docs/scp_plugin_tutorial.md) and shows `search-file -plugin scp -instance <name>`, SSH-backed directory drill-in, file download routing, `@N | add-file -instance ...`, and `add-file -plugin scp -instance <name>` uploads.
- The repo also includes a built-in HydrusNetwork plugin in [plugins/hydrusnetwork/__init__.py](plugins/hydrusnetwork/__init__.py). Its Hydrus client API now lives in the plugin-owned package [plugins/hydrusnetwork/api/__init__.py](plugins/hydrusnetwork/api/__init__.py), its registry-facing store adapter lives in [plugins/hydrusnetwork/store_proxy.py](plugins/hydrusnetwork/store_proxy.py), and its heavy internal operations live in [plugins/hydrusnetwork/store_backend.py](plugins/hydrusnetwork/store_backend.py). This `plugins/<name>/api/` package shape is the intended pattern for plugin-owned API helpers going forward. The plugin resolves configured Hydrus instances directly from plugin config instead of routing back through `Store.registry`; the proxy exists only so generic store callers can still target configured Hydrus stores. [API/HydrusNetwork.py](API/HydrusNetwork.py) and [Store/HydrusNetwork.py](Store/HydrusNetwork.py) are legacy compatibility shims only, and store discovery prefers the plugin-owned Hydrus hook over those shims.
