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.

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

Ruby 2.0.0 or later.

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"

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.

For a list of commands:

(rdb: 1) help

Most commands are described in rdebug's man page

$ gem install gem-man
$ man rdebug

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

Please give us your feedback.

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

Please report them on github.

All ruby's debugger programmers.
