説明
Describe the issue
Integer literals in C++ may be written as 1'000'000'000 instead of 1000000000 for greater readability. When this is used inside a #define, if breaks highlighting which treats the rest of the code as being inside a string.
Which language seems to have the issue? cpp
Are you using highlight or highlightAuto?

Sample Code to Reproduce
#include <iostream>
#define INF 1'000'000'000
int main() {
int a = INF;
return 0;
}
Expected behavior The token 1'000'000'000 should be highlighted as a number, and the following code should also be highlighted normally, instead of as if it is inside a string:
Additional context
The snippet below seems to be highlighted fine, so the issue is likely the interplay between quote-separated literals and defines.
#include <iostream>
int f(int x) { return f(2'000); }
int main() {
int a = 1'000'000'000;
int b = f(1'000);
return 0;
}
