Know the line number of an error

[bblanco]

Hello,

Firstly, sorry for my bad english.

We have a JS file where we catch an exception. We need to know how
Firebug knows the number of error line, to show it in the console
using a function that we have create. Thanks!

Sometimes the error line number is in the error message. To look just
print out the exception properties:
catch(exc) {
for ( p in exc)
...output p and exc[p]
Firebug also grabs the call stack by setting a debugger callback
errorHook.

Do you know about Firebug->Script->BreakOnError? If you set this you
will stop on the error.
