When running a program from the command-line, I get the following  
errors:  
from /usr/local/lib/site\_ruby/1.8/wordnet/lexicon.rb:211:in  
`lookupSynsetsByKey' from /usr/local/lib/site_ruby/1.8/wordnet/lexicon.rb:209:in`each’  
from /usr/local/lib/site\_ruby/1.8/wordnet/lexicon.rb:209:in  
`lookupSynsetsByKey' from /usr/local/lib/site_ruby/1.8/wordnet/synset.rb:876:in`fetchSynsetPointers’  
from /usr/local/lib/site\_ruby/1.8/wordnet/synset.rb:870:in

from /usr/local/lib/site\_ruby/1.8/wordnet/synset.rb:869:in  
`synchronize' from /usr/local/lib/site_ruby/1.8/wordnet/synset.rb:869:in`fetchSynsetPointers’  
… 16 levels…  
from ./ruby\_src/wordnet/rwfinder.rb:29:in `each' from ./ruby_src/wordnet/rwfinder.rb:29:in`find\_related\_words’  
from ruby\_src/inference/xvo\_qa.rb:101:in `find\_answer’  
from ruby\_src/inference/xvo\_qa.rb:170

Is there some option I can use to display the “16 levels” of errors,  
instead of having them hidden? Thanks.

That’s one error and a stack trace for said error. Whatever it was it  
happened in /usr/local/lib/site\_ruby/1.8/wordnet/lexicon.rb on line  
211 but it was probably caused by some code in ruby\_src/inference/  
xvo\_qa.rb at or around line 170. The middle stuff likely had nothing  
to do with the exception (which is why ruby omitted it from the stack  
trace).

If you explicitely catch the error, you can get to it through the  
backtrace method:

begin  
#do stuff  
rescue =\> e  
puts e.to\_s  
puts e.backtrace.join("\n")  
end
