debugger could use better message when --debug is not set
---------------------------------------------------------
Key: JRUBY-4935
URL: http://jira.codehaus.org/browse/JRUBY-4935
Project: JRuby
Issue Type: Improvement
Environment: 1.5.1 xp
Reporter: Roger Pack
Assignee: Thomas E Enebo
Currently if you have
require 'ruby-debug'
debugger
and do *not* pass it the --debug flag, it outputs a warning (which is good),
but then forces you to step through the debugger source code itself, ex:
C:\dev\lists\in_transit_lists>\installs\jruby-bin-1.5.1\jruby-1.5.1\bin\jruby
--debug differ.rb
[7, 16] in differ.rb
7
8
9 unless (line[0] =~ /das_no_apid/)
10 require 'ruby-debug'
11 debugger
=> 12 line[0] =~ /dgs:(\d+)/
13 all_awol << $1
14 end
15
16 }
differ.rb:12
line[0] =~ /dgs:(\d+)/
(rdb:1) exit!
C:\dev\lists\in_transit_lists>\installs\jruby-bin-1.5.1\jruby-1.5.1\bin\jruby
differ.rb
C:/installs/jruby-bin-1.5.1/jruby-1.5.1/lib/ruby/gems/1.8/gems/ruby-debug-base-0.10.3.2-java/lib/ruby-debug-base.rb:214
warning: tracing (e.g. set_trace_func) will not capture all events without
--debug flag
[162, 171] in
C:/installs/jruby-bin-1.5.1/jruby-1.5.1/lib/ruby/gems/1.8/gems/ruby-debug-0.10.3/cli/ruby-debug.rb
162 # in order to be back in your debugged program rather than the
163 # debugger. Settings _steps_ to 0 could be useful you want to stop
164 # right after the last statement in some scope, because the next
165 # step will take you out of some scope.
166 def debugger(steps = 1)
=> 167 Debugger.start unless Debugger.started?
168 Debugger.run_init_script(StringIO.new)
169 if 0 == steps
170 Debugger.current_context.stop_frame = 0
171 else
I'm not sure what would be best to do about this, but it was unexpected. At
the least output another warning, I would.
Thanks!
