title: config_filename
---
type: property
---
summary: The filename of the plugin config.
---
body:

This property returns the path to the file that holds the config for this
plugin in the loaded project.  This is by default in `configs/<plugin-id>.ini`.
Plugins could override this in theory but it's not recommended.  The primary
use of this property is to track dependencies.

For a convenient way to load the config see [get_config](../get-config/).

## Example

```python
from lektor.pluginsystem import Plugin
from lektor.context import get_ctx


class MyPlugin(Plugin):

    def on_setup_env(self, **extra):
        color = self.get_config().get('color')
        def get_css(artifact_name='/static/demo.css'):
            ctx = get_ctx()
            @ctx.sub_artifact(artifact_name, sources=[
                self.config_filename])
            def build_stylesheet(artifact):
                with artifact.open('w') as f:
                    f.write('body { background: %s }\n' % color)
            return artifact_name
        self.env.jinja_env.globals['get_css'] = get_css
```
