Intellisense for ="" needs Ctrl + Space to wake up

[floralan]

inside a tag, if I have a = before "" or {}, eg: <div if:true="">, or <div if:true={}>, I need Ctrl + Space to wake up intellisense so I can have a autocomplete list for "" or {}. But for tag, I can have a dynamical autocomplete list whenever I type a character, the intellisense is automatically waked up by user typing a character.
Can you point out to me which lines/block of code in this repo that define this behavior? Our team is developing an extended html language server based on this repo, and we want a autocomplete list for {} but without asking user to use Ctrl + Space to trigger the intellisense.

Steps to Reproduce:
1, go to a html file
2, <div if:true=""
3, move your cursor away, then move it back inside ""
4, typing a character does not trigger a autocomplete list
5, using Ctrl + Space, you can see a autocomplete list.

Provided I correctly understand what you are asking, this is the wrong repo. The correct one is the mainline vscode repository.

The built-in extension for html-language-features has a file called htmlServer.ts that controls what characters trigger the retrieval of completion items.

See line 196 where it defines the server capabilities as completionProvider: clientSnippetSupport ? { resolveProvider: true, triggerCharacters: ['.', ':', '<', '"', '=', '/'] } : undefined,.

Change the character list to include a-z and you should see the behavior you want.
