wxruby development - Feb 2009 - About predicate methods convention for wxRuby-2.0

Hi all,

wxRuby is already good at complying with Ruby conventions for
predicate methods :
Foo#is_ready => can be also used as Foo#ready?

I''m currently improving the RichTextCtrl sample and I''m using
several
methods like :
can_undo, can_redo, ...
There are also methods like has_selection, has_character_attributes, ...

For these methods, what about adding aliases with an ending ?
I''d really prefer write something like :

if my_richtextctrl.can_undo?
....

This can be defined as a general naming rule scheme.

Cheers,

Chauk-Mean.

Should be fairly easy to modify in the existing system.  As it sits now, the
way we get around some things, is by simply utilizing method_missing()
method.  I don''t see why it can''t be regex''ed to
determin if it should be a
question.

I''m thinking something like:

if sym.to_s =~ /[can|has]_[\w+|_]+\?/
  sym = (sym.to_s[0..-2]).to_sym
  self.__send__(sym,*args)
end

I''m in favour of this, and of doing it how Mario suggests. There are 
other classes that would benefit eg Window#has_style. I''ll put a patch 
in later today, unless you want to go ahead and do it first

I''m not at home and I don''t have full access to internet.
So put a patch on behalf me :-)

Done. BTW, are you subscribed to wxruby-svn-commits?

Not yet but I will do it. Until now, I was just following the
corresponding mailing list archive.

Regarding this patch, will you also update the wxRuby overview doc page ?
I can do it tomorrow if you want.

Cheers.
