Switch statements don't fully compile with curly braced anon function cases #55

Open w00tyd00d opened 10 months ago

w00tyd00d commented 10 months ago

Describe the bug

Switch statements that use an anonymous function (specifically with curly brackets) within a case will prevent any subsequent cases from being compiled. Since it needs curly brackets for it to bug, it seems like it's an error in the parser picking up the curly bracket to end the switch when it shouldn't.

To Reproduce

  1. Create a switch statement in any .jmc file.
  2. Use an anonymous execute function within a case that uses curly brackets. Any following cases will be ignored by the compiler.

Temporary workaround: add a break statement.

switch ($switch_var) {
    case 0:
        execute run $result = 0;
    case 1:
        execute run $result = 1;
    case 2:
        execute run {
            $result = 2;
        }
        break;
    case 3:
        execute run $result = 3;
}

compiles to what's expected.
