Ruby Interactive Shell

ruby-talk
1

Hello,
I'm looking for a Ruby interactive shell where I can paste snippet of
codes (rather than typing them in). eval.rb doesn't do it (or I haven't
found a way to make it do it).
Thanks!

Tried this? http://rubyforge.org/projects/fxirb/

There is an answer to your question at the bottom of this page:

<snip>
If you add this to your .irbrc file:
IRB.conf[:PROMPT][:XMP][:RETURN] = "\# => %s\n"

and start with irb --prompt xmp you'll have a great session for copying
and pasting code.

IRB comes with your Ruby installation.

Kind regards

If you are emacs user, ruby-mode provides that (C-c C-r ruby-send-region).

irb --prompt xmp you'll have a great session for copying

and pasting code.

But you can't paste code that contains '?' because IRB wil think it shoulds autocomplete.
Also irb crashes a lot.

Thanks for the lead. However, I can't find an .irbrc file anywhere in
my machine (Windows XP). Where is it located?

Thanks,

If nothing else works, or works well, I may have to -- sigh -- look at
emacs.

My fault, I'm afraid - I've had zero time to work on this lately :frowning: I'll
try to have the basic keybindings finished by the end of the week and
put out a 0.01 release. The CVS version already has indenting and some
level of dedenting working, which is the other half of what I wanted
before I released it. Forthcoming features (short term):

1. A few decent key bindings
2. Multiline edit
3. Integration with ihelp

Feature requests happily accepted. I'm also pondering an IRC-style input box
and output pane - any thoughts?

Say what? I've been an enthusiastic Ruby/Irb user for around 2 years
now and I've *never* seen irb crash. What platform are you running
on?

I use cygwin when on windows. With cygwin your "C:\Documents and
Settings\user_name" directory is your home directory. So you put it in
there.

Your probably using the one-click installer if irb is crashing on you
:slight_smile: - I had that experiance too - I am not sure what the answer is under
that setup.

Say what? I've been an enthusiastic Ruby/Irb user for around 2 years
now and I've *never* seen irb crash. What platform are you running
on?

I'm in a PC platform, WinXP as Operating System.
Irb crashes mainly when I use the autocompletion (the bigger the number of possibilities the worse)or when I'm overriding a method.

It says... (let me crash it now):
"irb(main):003:0* c:/ruby/lib/ruby/1.8/irb/workspace.rb:52: [BUG] Segmentation fault
ruby 1.8.2 (2004-12-25) [i386-mswin32]

This application has requested the Runtime to terminate it in an unusual way.
Please contact the application's support team for more information."

I don't know wether it has been reported already, but always that I type a variable name, press Enter and then Tab it crashes.

>> a = 1
>>a.
<<press tab>>

crash!

But it also crash a lot in day by day work.

Its the same under the one-cick installer.

I have this problem too.. it is very annoying. I work with Linux
during the day but when I get home I only get to use WinXP. Not
having irb handy removes a certain amount of the joy from Ruby. I was
told that installing new readline .dll and .so files could help this
but it doesn't seem to make a difference.

I had hoped that FXirb would address this but it doesn't seem to
support autocompletion yet.

Anybody know a way of getting the one-click irb to behave?

it is a known problem, if you look at the archives.
Sadly it seem noone has a clue on how to fix it :slight_smile:
Even if, IIRC, someone hinted it could relate to something like readline/cmd.exe's output buffer being overflowed, and in fact, if you try autocompleting a constant it seem to run fine (provided you did not set too much constants :), while it crashes if you try to expand something like "Object.<tab>".

PS
please consider avoiding top-posting, it is a bad habit :slight_smile:

If anyone has a solution, I would implemented in the one-click installer in
a heartbeat!

Agreed.. sorry, gmail doesn't seem to have a preference and this one
slipped through.

On a different note, anyone familiar with FOX and/or IRB care to
comment on the following?

I've just taken a look at the source for WinIrb and was wondering how
hard it would be to add an optional sidebar with a list of all
declared local_variables and perhaps their values if they are trivial
objects. I think this would be very useful for those shell sessions
where you are making it up as you go along. Would this be difficult?

Secondly, I wanted ot see if I could add tab completion, hooking the
tab key up seems easy but what method should be called to get irb to
return a list of possible solutions?
