[ruby-dev:10341] list and quit command in debug.rb

わたなべです.

1.5.4 の debug.rb が使い辛いというかバグってる気がします.

% ruby -r debug -r ping -e 0
Debug.rb
Emacs support available.

/usr/local/lib/ruby/1.5/ping.rb:40:
(rdb:1) l
[35, 44] in /usr/local/lib/ruby/1.5/ping.rb
no sourcefile available for /usr/local/lib/ruby/1.5/ping.rb
(rdb:1) q
really quit? (y/n) y
/usr/local/lib/ruby/1.5/debug.rb:423:in `exit': SystemExit
        from /usr/local/lib/ruby/1.5/debug.rb:423:in `debug_command'
        from /usr/local/lib/ruby/1.5/debug.rb:219:in `catch'
        from /usr/local/lib/ruby/1.5/debug.rb:219:in `debug_command'
        from /usr/local/lib/ruby/1.5/debug.rb:617:in `trace_func'
        from /usr/local/lib/ruby/1.5/debug.rb:768
        from /usr/local/lib/ruby/1.5/debug.rb:769
        from /usr/local/lib/ruby/1.5/ping.rb:40

場所までわかってるんだから表示してよとか, なぜ SystemExit に
なっちゃうのとか.

いまはこうしてます.
