[ruby-talk:00453] Re: interactive ruby, debugger

Hi, ....Guten Morgen!

...As gotoken-san saying, in Japan, many students in department of
technology learn German as the second foreign language.
I, as well as them, took German, but I can remember little
German grammar, pronounciation, and spelling...
So, all I can say when I meet the German on the street,
"Guten Morgen! May I help you?" ...ahh..that's not German...

I am also very glad to see you whose knowledge is deep about programming.
I have to appreciate gotoken-san who introduces ruby-talk and
invites people in ruby-list.

( I had mistaken here. Not 'trace.rb' but 'tracer.rb'. )

I agree to deeply. Ruby has almost powerful debugger-interface.
But! although that certain debugger in ruby package seems to be
enough powerful and simple, it seems that it is not used so much...
I do not know the reason why... As you said, lack of ruby-debug.el?
confortable GUI? humm....

BTW, I like vi for editing. I never use ruby-mode.el. :-)

Thank you for explanation. Although I use only LaTeX instead of (raw)TeX,
I has seen much command which starts by '\'.
You created your hand-written signature! using MetaFont! That's cool...

Now I know, unlike '\cle', '\NaHi' causes a compilation error.
