[[extension]] how to get link address when hovered - vscode-extensions

Question

I want to get the whole link address, but with the hoverProvider, I can only get the part of hoverd range.
here is the activate code and the result
export function activate(context: vscode.ExtensionContext) {
// Use the console to output diagnostic information (console.log) and errors (console.error)
// This line of code will only be executed once when your extension is activated
const disposal = vscode.languages.registerHoverProvider("javascript", {
provideHover(document, position, token) {
const range = document.getWordRangeAtPosition(position);
const word = document.getText(range);
return new vscode.Hover(
word
);
},
});
context.subscriptions.push(disposal);
}
so how to get the whole link 'https://www.youtube.com'?

Answer 1

According to the documentation, the getWordRangeAtPosition method allows you to define a custom word definition with a regular expression. A good regular expression to match a URL can be found in this answer.
Thus, in your case, you'd simply have to add a regular expression to the getWordRangeAtPosition method:
provideHover(document, position, token) {
const URLregex = /(https?:\/\/)*[-a-zA-Z0-9#:%._\+~#=]{1,256}\.[a-zA-Z0-9()]{1,6}\b([-a-zA-Z0-9()#:%_\+.~#?&//=]*)?/gi;
const range = document.getWordRangeAtPosition(position, URLregex);
const word = document.getText(range);
return new vscode.Hover(word);
}
