irb/completion BUG?
15857 [phasis@ha an] When  I try irb -r irb/completion and type "ab.<TAB>",
15865 [keiju@is it ] Perhaps, You use an old version of irb/completion. Down load from RAA.

If you want explicit instvar definitions...
15858 [sma@3p us .d] To allow a better documentation of classes, I added a "var" method to

Experimental "in" operator for collections
15863 [sma@3p us .d] There's one thing where I prefer Python over Ruby.  Testing whether an
+ 15866 [mike@le to .] object.in? array
| 15885 [sma@3p us .d] Sure. This was my first try but then I thought it might be interesting
+ 15897 [hal9000@hy e] I've been in favor of an "in" operator for awhile...
| 15971 [sma@3p us .d] Why?
| 16007 [hfulton@au t] Just because changes to the core language should be
| + 16016 [benoit.cerri] I agree wholeheartedly.

+ 15915 [matz@ze ab t] I like this idea.  My only concern left is whether "include?" is a

  + 16009 [patrickdloga] I would regret having more reserved syntax. The beauty of an simple
    16053 [sma@3p us .d] It is probably a matter of personal taste.

embedded ruby
15871 [wjl@mi dl ss] Has anyone had success embedding a ruby interpreter?
+ 15873 [decoux@mo lo] Yes,
| 15879 [wjl@mi dl ss] Well perhaps my problem is that I was following the documentation I
| 15881 [Dave@pr gm t] Nope - this is a bad example, and I've added an errata entry for
+ 15878 [elanthis@us ] Yep!  Just last week I got one running beautifully in AweMUD.  ^,^
| + 15883 [tspilman@ho ] That would mean writing my own parser for ruby.... that seems a bit of a
| | 15900 [elanthis@us ] Why do you have to write a parser?  Just load the Ruby code, and then use stuff like rb_funcall() to execute certain methods.
| + 15914 [decoux@mo lo] No. You have not understood. For example in an extension, or an embedded

Ruby and SWIG
15874 [mlang@ho e. ] Did anyone use latest SWIG cvs with ruby wiht positiv results?
15877 [fukusima@go ] Ruby support in the latest cvs version may be broken.

ssh interface?

15892 [gnhurst@hu s] It is a ruby version of 'zebedee', which is a freeware implementation

Q about TrueClass & FalseClass
15886 [sma@3p us .d] Is there any special reason why TrueClass and FalseClass are direct
+ 15896 [hal9000@hy e] Or do it trivially in Ruby. Though it's somewhat meaningless.
+ 15905 [feldt@ce ch ] * introduce Boolean class; super of TrueClass, FalseClass
  15909 [matz@ze ab t] But I'm not sure how useful it is in the dynamic typed language like
  15973 [sma@3p us .d] Good point.  You're right.  I forgot about that.

How to enumerate known subclasses?
15887 [sma@3p us .d] In Smalltalk, any class knows its subclasses (at least the loaded
15911 [matz@ze ab t] How about making a class/module relation table at first by enumerating
15974 [sma@3p us .d] Sure. That could be easily added but are there any arguments against
15993 [matz@ze ab t] Mostly implementation issue.  Implementing subclasses array requires

Embedding Ruby in another program

Dir[]

+ 15906 [wayne.blair@] Here are a couple of hacks that  might get you what you want.  If anyone

| 15936 [todd@de ig s] I noticed (maybe this is a problem with Ruby) that all the directory names
+ 15908 [matz@ze ab t] Hmm, ruby 1.7 allows you to escape space by \.
| 15921 [mike@le to .] Why should spaces be escaped? Why would a space be a delimiter in this method?
| + 15933 [matz@ze ab t] Mostly historical reason.  Hmm, let me think about it.
| + 15935 [benoit.cerri] I agree that this would be more intuitive and would also take care of the

15918 [tammo.freese] I currently have to work on development/maintenance of a VBA Excel

Block arguments vs method arguments
15923 [mike@le to .] Why is block arguments definition so different from method arguments definition?
+ 15925 [decoux@mo lo] It's best to see |x, y, z| as a multi-asssignement
| + 15926 [mike@le to .] Why aren't they arguments? or why aren't methods arguments a multi-assignement?
| | + 16045 [r2d2@ma .a c] Neither do I. I hope that when we have a working <...>, |...| will become
| | | 16070 [hal9000@hy e] to
| | | + 16076 [matz@ze ab t] This is a price for a mistake I made.  I feel really sorry that YOU
| | | | + 16104 [hal9000@hy e] Speaking only for myself... this guilt is surely misplaced.
| | | | + 16132 [spwhite@ch r] How about this for another approach?
| | | + 16081 [ser@ma s. er] Hear, hear.  The thought of using <...> makes me cringe.
| | |   16088 [dnm@po ox co] I suppose having my first post weigh in on a syntax issue is as good as
| | |   16089 [mirian@co mi] I agree... and I'm just starting to get the hang of this language, so
| | |   16090 [gc@ma dr ke ] Hey! -- If I count right, 4 persons (Sean Russell, Hal E. Fulton, Dan
| | |   + 16095 [dnm@po ox co] I'm definitely meddling in something I don't understand fully here, but
| | |   + 16096 [ser@ge ma e-] 1) There are better (IMHO) solutions for the problem.  I, personally, liked
| | |   | + 16098 [gc@ma dr ke ] That isn't a big deal since we will use a "closed" version here, sticked
| | |   | + 16106 [hal9000@hy e] they
| | |   | + 16120 [matz@ze ab t] I don't think it's better, because
| | |   | | + 16133 [mike@le to .] What about "(...)"?
| | |   | | + 16137 [gnhurst@hu s] It seems to me that this sheds new light on the problem, and
| | |   | | | 16139 [matz@ze ab t] It's better looking, but may cause syntax conflict, e.g.
| | |   | | | 16141 [spwhite@ch r] It needs upgrading if it lacks the version keyword. :)
| | |   | | + 16145 [ser@ge ma e-] Yes.  The only way this would be a Good Thing would be if the scoping rules

| | |   | |   | 16187 [ser@ma s. er] Aaaaaauuuugh!!!!
| | |   | |   + 16167 [matz@ze ab t] Yes.
| | |   | |     16186 [ser@ma s. er] Wow.  Duh.  Why did I miss this?
| | |   | |     16193 [matz@ze ab t] Any variables other than local variables would NOT be allowed in <..>.
| | |   | + 16135 [ugly-daemon@] I don't like either : or < >. Someone here made the suggestion that we use ( )
| | |   + 16105 [hal9000@hy e] True, but let's improve the semantics without injecting too much noise
| | + 16072 [matz@ze ab t] They're what I'm trying to achieve.  Hard part is keeping minimum
| + 15928 [decoux@mo lo] a block is defined independantly of |x, y, z| not a method.
| | + 15930 [mike@le to .] I don't understand. Blocks have arity, their arguments are not independant.
| | + 15937 [decoux@mo lo] [1, 2].each {|x, y| }
| + 16159 [alwagner@tc ] Would one of you nice people on this thread please explain what the "problem"
|   + 16163 [mike@le to .] This thread started because I was intrigued by the syntax of block arguments not being the same as method arguments (ie, you must use |a,| to expect exactly one argument). I was missing that block arguments are not really *arguments*.
|   | + 16165 [decoux@mo lo] Another possibility is to don't change ruby and have only ||. The
|   | + 16169 [matz@ze ab t] I proposed three changes before (forgot message number).
|   + 16168 [matz@ze ab t] There're TWO closely related but different problems.
|     16171 [alwagner@tc ] I don't know what this means.  That yield calls a block multiple times?
|     16235 [mike@le to .] a, b, *c = <the arguments given to yield>
+ 15931 [matz@ze ab t] Block parameters are originated from iteration variables, which can be
  15941 [mike@le to .] I like that.
