How to correctly use collectCandidates()? about antlr4-c3 HOT 5 CLOSED

A token index is the index of the token in the token stream, not a character index. What you first have to do is to take your caret position and find the correct token index for that. You can do that by simply iterating over the token stream and find the token that encloses the caret position.

Say I have this select name from u|sers query and caret position is in the last token.
By iterating over the token stream, I need to find the token index that has caret position right?

let index=-1;
for(let token of tokenStream.tokens) {
    console.log(token.type + " : " + parser.symbolicNames[token.type]);
// TODO find caret index
}
// index = 3

Correct.

I noticed that tokens are protected protected tokens: Token[]; in ts. How to get tokens in ts do you know?

Easy, check the C3 source how it is done there.
