Description

I want to know if there are any experts who have customized constants, such as entering 'Persion.'` So it will prompt operations such as'. name,. id,. sex '. I have seen that the API needs to use' registerCompletionItemProvider 'with' triggerCharacters', but I cannot see how to use them specifically. Please guide me
