Monaco Editor Playground Code
monaco.editor.create(document.getElementById('container'), {
value: `
int main() {
auto _ = R""( content )"";
}`,
language: 'cpp'
});
Reproduction Steps
paste the code in the js section and observe the resulting highlight being wrong
Actual (Problematic) Behavior
The raw string end isn't properly detected and the string highlighting continues until the end of the file
Expected Behavior
the raw string's end is properly detected
Additional Context
C++ raw string have the form R"delimiter(content)delimiter" where the delimiter is a (possibly empty) sequence of characters that may include quotes. when the delimiter contains quotes, the end isn't properly detected. having looked at the sources, while I don't understand everything, it looks a lot like this regex is responsible, as it exclude the quotes from the characters making up the delimiter (there's a mismatch with the regex for the opening delimiter):
raw: [
[
/(.*)(\))(?:([^ ()\\\t"]*))(\")/,
