displaying all errors

[Ell Quing]

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

from /usr/local/lib/site_ruby/1.8/wordnet/lexicon.rb:209:in

... 16 levels...
from ./ruby_src/wordnet/rwfinder.rb:29:in `each'

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 =3D> e
puts e.to_s
puts e.backtrace.join("\n")
end
