Hi folks -

I spent most of yesterday looking around these forums trying to get NB 6.9 to debug my Rails 3.0 app running with Ruby 1.9.2 (installed via rvm). When I try to run my app in debug mode I get this error:

Fast Debugger (ruby-debug-ide 0.4.9) listens on :53116
/Users/wkocik/.rvm/gems/ruby-1.9.2-p0/gems/ruby-debug-ide19-0.4.12/lib/ruby-debug-ide.rb:123:in `debug_load'
/Users/wkocik/.rvm/gems/ruby-1.9.2-p0/gems/ruby-debug-ide19-0.4.12/lib/ruby-debug-ide.rb:123:in `debug_program'
/Users/wkocik/.rvm/gems/ruby-1.9.2-p0/gems/ruby-debug-ide19-0.4.12/bin/rdebug-ide:87:in `<top (required)>'
/Users/wkocik/.rvm/gems/ruby-1.9.2-p0/bin/rdebug-ide:19:in `load'
/Users/wkocik/.rvm/gems/ruby-1.9.2-p0/bin/rdebug-ide:19:in `<main>'
Uncaught exception: no such file to load -- script/rails

It seems odd to me that it mentions ruby-debug-ide 0.4.9; I don't even have that gem installed:

wkocik$ gem list -d ruby-debug-ide

*** LOCAL GEMS ***

ruby-debug-ide19 (0.4.12)

I've added -J-DrubyDebugIDEName=ruby-debug-ide19 to my netbeans_default_options in netbeans.conf. This hasn't solved it, though it has changed its behavior. Before I did that the debugger failed to start, but showed no message. Looking at NB's log I found it was looking for, and failing to find, the ruby-debug-ide 0.4.9 gem.

I also replaced my org-netbeans-modules-ruby-debugger.jar file with one that Erno posted in another thread to try to help out a couple of folks who were seeing NB try to launch their Rails 3.0 projects by calling script/server, which no longer exists. It's now correctly trying to call script/rails, but somehow failing to find it.

When viewing the gems in the platform I've got the project set to, I do see all the appropriate gems including Rails 3.0.0. I also tried using Ruby 1.9.1 on the off chance that maybe NB didn't recognize 1.9.2 as 1.9, but that didn't make a difference.

I'm stumped. I have no idea what to try next. Does anyone else?

Thanks,
-Bill

Update: I've just realized that my issue is an exact duplicate of the one noted in this thread:

Hi bkocik,

I feel your pain, I have also now spent many hours trying to figure out what the problem is and how to solve it, so far no luck.

As you noted this is the same problem myself and others have experienced, hopefully someone involved in NB development will get us an answer soon.

Cheers,

Etienne.

Erno might be busy, but I expect he'll jump in here sooner or later and bail us out. He's always very helpful.

I actually had this working at one point early on, but then I decided I didn't like NetBeans having a different idea of my GEM_HOME than my command-line environment did because it meant that bundler on the command line wasn't synched with bundler in NB, so I went messing around with things. Ever since then I haven't been able to recreate those initial conditions under which it actually worked, and I don't know why.

Hi guys,

Sorry for the late reply, I've been away. It seems that the 1.9.2 /
Rails 3 / RVM / ruby-debug 0.4.9/10 combination is not working too well
(or at all) with NB. I will need to dig deeper to find out the root
cause. If you want to return the IDE to the initial state you can remove
the userdir (you can see where it is in Help | About) or run the IDE
using an alternate userdir: http://wiki.netbeans.org/FaqAlternateUserdir
(I'd recommend trying an alternate userdir first).

Unfortunately the situation at the moment is that I don't have much time
to work on NB Ruby, but I will try to get back to this when I have a
chance. In the meanwhile I will keep monitoring the list and try to help
and provide quick fixes when I can.

Thanks,
Erno

"...I don't have much time to work on NB Ruby..."

Not really something you want to hear from the folks who make the very IDE that I've chosen to go with for my Ruby/Rails development.

Hi Erno...

Paul · Posted via mailing list.

Say it ain't so, Errno!

I've appreciated your quick answers and fixes in the past, and I look
forward to you being back in the saddle soon.

I do want to say that the bug described below is kind of important at
the moment, now that Rails 3 is officially released, and RVM / Ruby
1.9.2 / Rails 3 seems to be the recommended setup. I'm running that
setup on the server, but I'm running 1.8.7 on my development machine
at the moment, hoping to slide by without anything unexpected
happening while waiting for your fix.

Hi all,

I did as Etienne said above + worked around the "no such file to load -- script\rails" by editing directly the ruby-debug-ide.rb file, aroud line 123
( d:/Ruby19/lib/ruby/gems/1.9.1/gems/ruby-debug-ide19-0.4.12/lib/ruby-debug-ide.rb:125:in `debug_load' )

sr = "d:/fourth/script/rails" # d:/fourth is my project's root, obviously
bt = debug_load(sr, options.stop, options.load_mode)

# and comment following line:
# bt = debug_load(Debugger::PROG_SCRIPT, options.stop, options.load_mode)

Then debugging is all of sudden peaceful again.

Based on what Nicholas did I think I have generalised it for multiple Ruby / Rails projects by replacing the line
bt = debug_load(Debugger::PROG_SCRIPT, options.stop, options.load_mode)
around line 125 of ruby-debug-ide.rb with

if Debugger::PROG_SCRIPT == 'script/rails'
ps = `pwd`.chomp+'/script/rails'
else
ps = Debugger::PROG_SCRIPT
end
bt = debug_load(ps, options.stop, options.load_mode)

I don't have the confidence to attempt a 'proper' solution but (in my limited experience - I am a newbie) I can't see what this doesn't work for.

I've done what @baldmark did and the server is starting now, but Netbeans won't stop at the breakpoints.

does it work for you guys, not much use otherwise.

update: I now followed the steps from Etienne as well and tried running the debugger from commandline and attaching Nebeans to it, still no luck

thanks

I also had a problem with breakpoints (which I reported in http://forums.netbeans.org/viewtopic.php?t=31492) but they mostly seem to work.

Hi,
just want to give an update. I downloaded the latest nightly, and I can use the debugger now.
