Byebug is a simple to use, feature rich debugger for Ruby 2. It uses the new
|
||
|
|
TracePoint API for execution control and the new Debug Inspector API for call
|
||
|
|
stack navigation, so it doesn't depend on internal core sources. It's developed
|
||
|
|
as a C extension, so it's fast. And it has a full test suite so it's reliable.
|
||
|
|
|
||
|
|
It allows you to see what is going on _inside_ a Ruby program while it executes
|
||
|
|
and offers many of the traditional debugging features such as:
|
||
|
|
|
||
|
|
* Stepping: Running your program one line at a time.
|
||
|
|
* Breaking: Pausing the program at some event or specified instruction, to
|
||
|
|
examine the current state.
|
||
|
|
* Evaluating: Basic REPL functionality, although [pry] does a better job at
|
||
|
|
that.
|
||
|
|
* Tracking: Keeping track of the different values of your variables or the
|
||
|
|
different lines executed by your program.
