Hello,  
Does anyone here know if Ruby 1.8.6 fixes the “BreakPointer” problem in  
Rails? The reason I ask is that I have been working with Curt Hibb’s  
InstantRails in Window (at last I have found a usable Rails system on  
Windows). Currently, I am on InstantRails 1.6, but Curt has made  
available InstantRails 1.7 which has the following components:

Instant Rails 1.7 contains the following major changes:

- Upgrades Ruby to version 1.8.6
- Upgrades Rails to 1.2.3
- Upgrades phpMyAdmin to version 2.10.0.2

Frankly, I am not at a stage where the latest and greatest matters to me  
since I am still learning Ruby and Ruby on Rails and InstantRails 1.6  
has worked fine for me. But if there is a compeling reason to upgrade  
from Ruby 1.8.5 to Ruby 1.8.6, or from Rails 1.2.2 to Rails 1.2.3 then I  
am not vested into any versions either since I don’t have any projects  
in production.

The only thing that I miss is the BreakPointer in “old” rails which I  
had when I started learning Ruby and Ruby on Rails last November.

Thanks for your time in advance and a big thank you to Curt again for  
making this fine package available to the Ruby and Ruby on Rails  
community which makes it usable on Windows. Unfortunately, I have to be  
on Windows majority of times due to job related reasons, but Curt’s work  
has made is possible for me to use Ruby and Ruby on Rails without having  
to reboot my dual boot machine all the time to go over to my preferred  
Fedora Core 5 installation.

Bharat

Ruby 1.8.6 will not fix the breakpointer-problem - thats for sure. The  
breakpointer relies on Binding.of\_caller. Binding.of\_caller itself uses  
an unintended behaviour of the ruby interpreter which was fixed in Ruby  
1.8.5. Until Rails integrates a fix for this, breakpointer will be  
broken.

There are other tools to accomplish what breakpointer does, for example  
[DATANOISE.COM](http://www.datanoise.com/ruby-debug/) , which has far more features  
(which also means that it is not as simple as breakpointer…).
