Hi all,

One of the happiest things for me in RubyConf2002 was
to meet readers of this summary.  Thanks again!


And, this is a summary of ruby-dev ML in these days.


---- ruby-dev #18613-18710 (2002-10-31 ... 2002-11-08) ----


[ruby-dev:18651] Enumerable#zip

  Matz implemented Enumerable#zip method, but he has not
  decide its behavior yet.

  Enumerable#zip is a method to mix some sequences(Array or
  Object which has to_ary method). But, when length of
  sequences are not same, the behavior is not clear.

    a = [1,2,3,4]
    b = [2,4]
    a.zip(b) #=> ?

   a.) a.zip(b) #=> [[1,2],[2,4],[3,nil],[4,nil]]

   b.) a.zip(b) #=> [[1,2],[2,4]]

   c.) a.zip(b) #=> [[1,2],[2,4],[3,nil],[4,nil]]
       b.zip(a) #=> [[2,1],[4,2]]

   e.) a.zip(b) #=> raise Exception (ArgumentError(?))

  There is a discussion whether Enumerable#zip is appropriate or not.

   ex.
    * Enumerable.zip(a, b, c...)
    * Array.zip(a, b, c...)
    * [a, b, c..].zip


[ruby-dev:18652] Re: 1.6.8 preview

  The first preview version of Ruby 1.6.8 is available.

    ftp.ruby-lang.org:/pub/ruby/1.6/ruby-1.6.8-preview1.tar.gz

    (2002/11/11: now second preview version of one is avalible.
    ftp.ruby-lang.org:/pub/ruby/1.6/ruby-1.6.8-preview2.tar.gz )
   

  This package is just only preview and it has a well known
  problem (dRuby's UnitTest is not passed). A patch to solve
  this problem has been made by nobu, but Matz does not have
  enough time to verify it.
  Moreover, Akinori MUSHA got a report that 1.6.8 preview1 made
  too many warning with -w option ([ruby-dev:18705]).


[ruby-dev:18683] Re: ERb

  Masatoshi SEKI released ERb 2.0b2.

    http://www2a.biglobe.ne.jp/~seki/ruby/erb-2.0b2.tar.gz  

  ERb is pure Ruby implementation of eRuby. If there is no
  problem, it will be in standard distribution of Ruby.
