I have very basic Rails 4 project (
There is a breakpoint at
I run it with ruby-1.9.3-p448, open http://localhost:3000/shops in browser to stop at the break point and try to get global vars (v g command)
I'm getting "*** Errno::ENOENT Exception: No such file or directory - -b"

It looks like debugger fails to evaluate $FILENAME for some reasons :(
The quick workaround for the problem would be filter $FILENAME out of list of global vars in ::Debugger::VarFunctions#var_global, but it is unclear why it is evaluated correctly in other situations.

It's possible this is happening because the rescues are too weak. Pull request to handle the above exception would be great

@cldwalker actually the problem is that Command#debug_eval throws :debug_error and the code you've pointed doesn't catch it.
Do you think it should?
