MessageActionItem should permit additional fields #411
Description
Although the LSP specification does not define it explicitly, from the definition of ShowMessageRequestClientCapabilities it follows that MessageActionItem can have additional fields:
messageActionItem?: {
/**
* Whether the client supports additional attributes which
* are preserved and sent back to the server in the
* request's response.
*/
additionalPropertiesSupport?: boolean;
};
However, lsprotocol does not permit this:
print(types.MessageActionItem(title="title", asdf="asdf"))
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
TypeError: MessageActionItem.__init__() got an unexpected keyword argument 'asdf'
(See the pygls issue)
