Byebug is a Ruby debugger. It's implemented using the TracePoint C API for execution control and the Debug Inspector C API for call stack navigation. The core component provides support that front-ends can build on. It provides breakpoint handling and bindings for stack frames among other things and it comes with an easy to use command line interface.

debase is a fast implementation of the standard Ruby debugger debug.rb for Ruby 2.0. It is implemented by utilizing a new Ruby TracePoint class. The core component provides support that front-ends can build on. It provides breakpoint handling, bindings for stack frames among other things.

Provide Ruby core source files for C extensions that need them.

Linecache is a module for reading and caching lines. This may be useful for example in a debugger where the same lines are shown many times.

debugger is a fast implementation of the standard Ruby debugger debug.rb. It is implemented by utilizing a new Ruby C API hook. The core component provides support that front-ends can build on. It provides breakpoint handling, bindings for stack frames among other things.

Turn Pry into a primitive debugger. Adds 'step' and 'next' commands to control execution.

In showing a long lists, sometimes one would prefer to see the value arranged aligned in columns. Some examples include listing methods of an object or debugger commands. See Examples in the rdoc documentation for examples.

Debuggers are great! They help us troubleshoot complicated programming problems by inspecting values produced by code, line by line. They are invaluable when trying to understand what is going on in a large application composed of thousands or millions of lines of code. In day-to-day test-driven development and simple debugging though, a puts statement can be a lot quicker in revealing what is going on than halting execution completely just to inspect a single value or a few. This is certainly true when writing the simplest possible code that could possibly work, and running a test every few seconds or minutes. Problem is you need to locate puts statements in large output logs, know which methods were invoked, find out what variable names are being printed, and see nicely formatted output. Enter puts_debuggerer. A guilt-free puts debugging Ruby gem FTW that prints file names, line numbers, code statements, and formats output nicely courtesy of awesome_print.

XML interface for debugger

Provides debugger with command and command arguments completion, compliments of bond.

A modular, testable, Ruby debugger using some of good ideas from ruby-debug, other debuggers, and Ruby Rails. Some of the core debugger concepts have been rethought. As a result, some of this may be experimental. This version works only on Rubinus 1.2.1 or higher.

As a result, some of this may be experimental. This version works only with MRI 1.8 and 1.9' See rbx-trepanning for a version that works with Rubinius, and trepanning and for something that works with a patched YARV 1.9.2.

Combine 'pry' with 'debugger'. Adds 'step', 'next', and 'continue' commands to control execution.

This gem adds a 'pry' command to invoke Pry in the current context.

needy_debugger is a less needy (or more if needs be), fast implementation of the standard Ruby debugger debug.rb. It is implemented by utilizing a new Ruby C API hook. The core component provides support that front-ends can build on. It provides breakpoint handling, bindings for stack frames among other things.

Add a JRuby-compatible debugger to 'pry'. Adds 'step', 'next', 'continue', `break` and `breakpoints` commands to control execution.

Metasm is a cross-architecture assembler, disassembler, linker, and debugger.
