I launch debugger in Ruby eclipse.
This message appears
ruby 1.8.6 debugger listens on port 4985
but then nothing seems to be happening - ruby thread shows as having started but the application doesn't kick off.

Debug current instruction pointer is sitting on
I18n.load_path << "#{File.dirname(__FILE__)}/active_support/locale/en.yml" in active_support.rb

I try to start the debugger again and again ; suddenly after a very long time (5-10 minutes usually but can be much longer) the application starts. After that has happened a number of the dormant threads take off.

Hi David,

Could you please check if you are using Fast ruby debugger (interacting
with the ruby-debug-base gem) or Built-in ruby debugger?

Generally, any debugger slows the application down, but ruby-debug-base
uses some native code to minimize the performance costs.
Built-in debugger works too, but it's quite slow, especially for large
applications.

Regards,
Alex

I have ruby-debug-0.10.3 gem installed on my computer. When I start Eclipse I get a window title 'Auto-install gems' which states that plugins have contributed local copies of the following gems for automaytic installation. I am invited to select which gems to have installed. The gems listed are

linecache
ruby_debug_ide
ruby_debug_base

I have tried to upload a screenshot of this window but cannot attach it successfully to this post.

I have selected to use both ruby_debug_ide and ruby_debug_base in my environment.

Could you please provide more details about your installation?
I am not sure where is "Auto-install gems" window coming from.

You can send attachment to my email address if eclipse newsgroup doesn't
accept it.

Alex

Hi David,

It's not DLTK window, I suppose it's coming from Aptana RadRails.

Alex

Hi David,

I think you can start at http://www.aptana.com/support

Maybe I need a little history lesson but it would appear that RDT fell into the hands of Aptana while in the meantime DLTK for Ruby emerged and gained prominence.

Would most Ruby developers using Eclipse have gone the DLTK path?

I have read some postings proclaiming that RDT was painful and developers had dumped it in favour of DLTK.
