verify errors are not colorized

[zwetan]

When a script dynamically load definitions

for example

#!/usr/bin/env as3shebang -el -ec

import shell.*;

var person_loaded:Boolean = Runtime.load( "Person.swf" );
trace( "Person loaded: " + person_loaded );

import test.as3examples.*;

var p1:Person = new Person( "John Doe", 21 );
trace( "p1 = " + p1 );

because the definition is in "Person.swf"

the line

var p1:Person = new Person( "John Doe", 21 );

will generate a VerifyError

Not only we want to catch this error but we also want to colorize it like other errors.

for ex

but here the problems

• the error occurs outside the script scope
• a try/catch around Runtime.eval() can not catch such errors

[zwetan]

a try/catch around Runtime.eval() can not catch such errors
because what happen internally is that the C++ already does a try/catch
and if an error is found it then stringify it to the script output.

by replacing Runtime.eval() with Runtime.returnEval()
we can return the output of the script into a string
and then we can test for some strings to check if a VerifyError occured

then we can format the output as if it was an internal script error

[zwetan]

Here the result

we do catch the error
but we remove the stacktrace (as it is not related to the script)
we apply options if they are enabled
etc.

other example with DEBUG enabled
