^ Checking if a field is read-only
210080 [ ni arobs.ro] Can you help me please and tell how can i check if a field is read only
210081 [farrel.lifso] You could check to see if the object responds to "field=".

210128 [bart.braem g] I'd like to be able to do

  | | + 210146 [wccrawford g] He has redefined the 'another' method in the child class.  But for some
  | | | 210220 [listbox juli] I am not saying I _need_ to do that, I was curious if it's at all
  | | + 210151 [jan.svitok g] The OP defined method zoo in Child as well, and wanted to call the
  | | + 210188 [nsmith5 umbc] class Child < Parent
  | |   210190 [dblack wobbl] But the Parent class has no hoo instance method, so calling super from
  | |   210198 [nsmith5 umbc] Exactly! That's the point I was getting at. It'd be nice if this would
  | |   210211 [dblack wobbl] It depends what you mean by "should" :-)  I think the current behavior
  | |   210219 [nsmith5 umbc] If I'm thinking correctly, self.class.superclass will point to the
  | |   210222 [dblack wobbl] No; it will point to the superclass of the class of self :-)
  | |   210327 [nsmith5 umbc] class A
  | |   + 210328 [decoux moulo] no, not really. self.class.superclass make reference to the superclass of
  | |   | 210331 [nsmith5 umbc] It refers to the metaclass of the superclass of B -- see Programming Ruby
  | |   | 210333 [decoux moulo] re read your example
  | |   | 210336 [nsmith5 umbc] the metaclass of the class.
  | |   | 210337 [decoux moulo] Well, it's well known : metaclass exist in Smalltalk, singleton class in
  | |   | + 210339 [nsmith5 umbc] That's great. Thanks for the info ;-) I'm referring to metaclass as stated
  | |   | | + 210341 [decoux moulo] Re read carefully "Programming Ruby", it was written by someone which know
  | |   | | | 210342 [nsmith5 umbc] Rather than making rash statements such as that, it'd be nice of you to
  | |   | | | 210459 [hal9000 hype] Be careful... ;)  Guy is one of the very smartest people
  | |   | | + 210457 [hal9000 hype] Does the 2nd edition say that??
  | |   | |   + 210532 [decoux moulo] Well the 2nd edition speak about the metaclass and there is a paragraph in
  | |   | |   + 210611 [NSMITH5 UMBC] Yes AFAIK I was referring to the 2nd edition (don't have the book in

  |   210162 [ mfp acm.org] wow, that's way too much work (plus thread-unsafe).
  |   + 210194 [dblack wobbl] This only works for superclasses, I think, whereas super just looks
  |   + 210746 [listbox juli] Don't know if my response went through but I wanted to say that this

  | 210147 [decoux moulo] No, not really
  | 210197 [m_goldberg a] You're right. I forgot to take into account that every Ruby method

^ How do I strip off the extra double quote or white space in the string when using assert_equal method
210141 [bhoang veran] charset="us-ascii"
210152 [ben bleythin] 1) If your external file is truly CSV (comma-separated values) use a CSV
210170 [bhoang veran] charset="us-ascii"
210203 [bhoang veran] Thanks for your help, Ben!
210345 [ben bleythin] Notice that that call to assert_equal is wrapped inside a method.  So

^ Can methods be part of a array
210142 [somc motorol] I am a newbie to this mailing list.
210148 [jan.svitok g] you can do ['aaa'.method(:size), 10.method("+")]
210156 [rick.denatal] Another approach would be to use Procs in the array instead of
