Bindex Build Status

When Ruby raises an exception, it leaves you a backtrace to help you figure out where did the exception originated in. Bindex gives you the bindings as well. This can help you introspect the state of the Ruby program when at the point the exception occurred.

Usage

Do not use this gem on production environments. The performance penalty isn't worth it anywhere outside of development.

API

Bindex defines the following API:

Exception#bindings

Returns all the bindings up to the one in which the exception originated in.

Bindex.current_bindings

Returns all of the current Ruby execution state bindings. The first one is the current one, the second is the caller one, the third is the caller of the caller one and so on.

Support

CRuby

CRuby 2.0.0 and above is supported.

JRuby

To get the best support, run JRuby in interpreted mode.

export JRUBY_OPTS=--dev

Only JRuby 9k is supported.

Rubinius

Internal errors like ZeroDevisionError aren't caught.
