Description

debugger2 is a fork of [debugger] (https://github.com/cldwalker/debugger) for Ruby 2.0.

It uses only external C-APIs. Not of Ruby core sources.

(and debugger is a fork of ruby-debug(19) that works on 1.9.2 and 1.9.3 and installs easily for rvm/rbenv rubies :)

I want to merge original debugger if it has no problem. So debugger2 may be obsolete. Feel free to give us your comments.

Install

First clone this repository:

git clone git@github.com:ko1/debugger2.git

Next, compile the extension:

rake compile

Build the gem package and install it:

gem build debugger2.gemspec
gem install debugger2*.gem

Supported Rubies

Ruby 2.0.0 or later.

Usage

Wherever you need a debugger, simply:

require 'debugger'; debugger

To use with bundler, drop in your Gemfile:

gem 'debugger2', :git => "git://github.com/ko1/debugger2.git"

Configuration

At initialization time, debugger loads config files, executing their lines as if they were actual commands a user has typed. config files are loaded from two locations:

  • /.rdebugrc (/rdebug.ini for windows)
  • $PWD/.rdebugrc ($PWD/rdebug.ini for windows)

Here's a common configuration (yeah, I should make this the default):

set autolist
set autoeval
set autoreload

To see debugger's current settings, use the set command.

Using Commands

For a list of commands:

(rdb: 1) help

Most commands are described in rdebug's man page

$ gem install gem-man
$ man rdebug

More documentation

I forked this project from https://github.com/cldwalker/debugger. Maybe it can work same as debugger'. However, now don't supportpost-motem' mode and `threading'.

Please give us your feedback.

Reason for Fork

Ruby 2.0.0 has debugger support API. No need to install internal headers.

Issues

Please report them on github.

Credits

All ruby's debugger programmers.
