[Github-comments] [geany/geany] Gi signals (#1038)

[Thomas Martitz]

Normally a plugin would connect using its own plugin object, this is what I expect for peasy based ones at least:

```
def on_document_new(self, doc):
  pass
def do_enable(self):
 self.geany_plugin.geany_data.object.connect("document-new", self.on_document_new)
```

In this case the signal connection is automatically cleaned up when `self` is destructed, i.e. when geany (via peasy) unloads the plugin.

I'm not sure we can enforce such behavior for all GI based plugins but I expect the most common cases are handled like above. 

Also, we can't enforce it for plain C plugins either (for non-geany_object signals) since those can too always use plain g_object_connect().
