How the insertion of closing quote works in Javascript plugin.

The JavaScript plugin uses the JSHtmlBridge cheater to do the cool things. See com.intellij.codeInsight.editorActions.TypedHandler#registerQuoteHandler(), but be aware, it's not part of the OpenAPI.

It's as easy as implementing QuoteHandler EP, like this:

Pay attention, that you need to include BAD_CHARACTER in the token set as well.

 public BnfQuoteHandler() {
 super(BnfTypes.BNF_STRING, TokenType.BAD_CHARACTER);
 }
}
