[ANN] fxirb 0.2.0 - Multiline Edit (and request for help

Martin DeMello

4/10/2005 4:28:00 PM

available at http://rubyforge.org/proje...

Finally got around to my 0.2 milestone, proper multiline editing.

You can now:

1. Paste in a multiline block of code and edit it immediately using all
four arrow keys

2. Enter a multiline block line by line, and have it occupy a single
multiline slot in the history once it's done

3. Edit a multiline history item using all four arrow keys

Associated behaviour change:

Up/Down arrows now only scroll history if not in multiline mode
PgUp/PgDn always scroll history

The other major change is the ability to pass in an on_exit block, which
is instance_evaled by the FxIRB widget when its internal IRB thread
exits. Usage:

fxirb = FXIrb.init(window, nil, 0,
LAYOUT_FILL_X|LAYOUT_FILL_Y|TEXT_WORDWRAP|TEXT_SHOWACTIVE)
fxirb.on_exit {exit}

This should make it possible to embed fxirb in another application, and
not have the whole application exit when IRB exits.

The target for the 0.3 and 0.4 milestones are a menu-and-button frame in
standalone mode, and an implementation of 'gets' (I really would like
some help with the latter - I don't know enough about IRB internals or
FOX to see what I need to do. To see the problem, just start up FXIrb
and type in "a = gets")

To use fxirb I need fox12 but am having difficulty using gem to install
it on Cygwin. What is the suggestion for getting fox ruby support for
Cygwin?


Cheers,

Sorry, I've never tried this - I just use the one-click installer.

http://www.fox-toolkit.org/in... suggests that fox compiles
cleanly under cygwin, at least.

Also, I'm not using any fancy fox features, so it should be possible to get
this running under Fox 1.0 if that is less problematic than 1.2. Let me
know if you need to go down that route, and I'll help port it back to
1.0 (IIRC porting it to 1.2 in the first place was trivial, but I don't
have a Fox 1.0 install around any more to check it).

Binkley,

Would you be interested in getting together sometime? Feel free to
give me a call. 713-807-9023.

Drat, I didn't mean to send to that address!

Thanks! I'm getting quite a nice flow between my editor and fxirb now!

btw, on XP some messages (streams?) seem to come out on the command window,
not the fx window e.g.
(irb):14: warning: parenthesize argument(s) for future version
(irb):14: warning: parenthesize argument(s) for future version

That sounds cool. I wanted to give it a try under Linux, but with my
existing fxruby installation (1.2.2) it segfaulted; then I upgraded my
fxruby to 1.2.5, which just hanged upon pressing enter.

What's the problem? As you can see, I can't try this now.

Can you paste in a sample session? Not seen this happen on Win2k.

I've not tested this at all under linux - I based it off Marco Frailis's
win32 fxirb. I should make that my next priority, actually - it's
somewhat more useful than a menu and button frame :).

The whole thing just hangs up (windows says 'this application is not
responding'). I thought it might be infinitely recursing
FXIRBInputMethod#gets, but it isn't, so I'm at a bit of a loss as how to
even debug it (no stack trace).

A line read by irb is evaluated in an IRB::Irb instance (that class is
defined in irb.rb). As I can read fxirb.rb, you didn't overwrite #gets
anywhere seeked by IRB::Irb upon method lookup. So what happens is that
the good old Kernel#gets is called.
