```python
@hookimpl
def register_output_renderer(datasette):
    return {
        ""extension"": ""test"",
        ""callback"": render_test
    }
```
We can add an optional third argument, `""should_suggest""`, which takes the same arguments as the callback but simply returns `True` or `False` depending on if the plugin can work for the current set of data.

If that dictionary key is omitted, Datasette will treat this test as returning `True`.","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",530653633,Mechanism for register_output_renderer to suggest extension or not,
