Comment #14 on issue 1914 by [email protected]: Capture correct line
numbers for Errors thrown in an eval.
http://code.google.com/p/v8/issues/detail?id=1914
@yangguo - I'm not sure if this issue is fully solved yet. Although the
Error object does contain the proper information for runtime errors,
compilation/parsing errors do not reveal line/column numbers.
For example, if I run the following code (using Chrome 23.0.1271.95 m):
```
var a = 1, b = 2;
try {
eval("var sum = a;\nsum += c;");
console.log(sum);
} catch(e) {
console.log(e.stack);
}
```
I get the following error, which includes the line/column number in my
eval'ed string:
```
ReferenceError: c is not defined
at eval (eval at <anonymous> (unknown source), <anonymous>:2:8)
at <anonymous>:4:2
at Object.InjectedScript._evaluateOn (<anonymous>:444:39)
at Object.InjectedScript._evaluateAndWrap (<anonymous>:403:52)
at Object.InjectedScript.evaluate (<anonymous>:339:21)
```
But, if I run this code:
```
var a = 1, b = 2;
try {
eval("var sum = a;\nsum += c);");
console.log(sum);
} catch(e) {
console.log(e.stack);
}
```
I get this error, which only shows the stack trace where eval is called:
```
SyntaxError: Unexpected token )
at <anonymous>:4:2
at Object.InjectedScript._evaluateOn (<anonymous>:444:39)
at Object.InjectedScript._evaluateAndWrap (<anonymous>:403:52)
at Object.InjectedScript.evaluate (<anonymous>:339:21)
```
Why would this be?
