Regular expressions aren't properly highlighted in certain scenarios #853
Description
in vscode 1.53.1
/foo/;
return /foo/;
throw /foo/;
yield* /foo/;
yield /foo/;
await /foo/;
export default /foo/;
if(_) /foo/;
else /foo/;
while(_) /foo/;
for(;;) /foo/;
for(_ in /foo/) /foo/;
with(_) /foo/;
do /foo/;
while(_);
void /foo/;
typeof /foo/;
/foo/ in /foo/;
/foo/ instanceof /foo/;
new /foo/;
!class extends /foo/ {};
/foo/[/foo/];
!/foo/;
~/foo/;
+/foo/;
-/foo/;
++/foo/;
--/foo/;
/foo/++;
/foo/--;looks like this:
as can be seen, regular expressions aren't properly highlighted:
- after
throw/export default - after
await/yield(but notyield*) - after
while(),for(),with(),do,else(but notif()) - after
in/of(infor..in/for..of) - after
void/typeof/new - as either operand of
in/instanceof - after
extends(inclass) - after unary
++/--
worse yet, this can break the highlighting of surrounding code:
yield /[[]/;
if(1) {
foo["bar"]();
a: { break a; }
} else return 123;
