Summary of ruby-dev 17609-17666:

[ruby-dev:17615] substitution at when-clause

Takaaki Tateishi proposed to extend the case-expression, so that
we can substitute a variable with the result of comparison '==='
at when-clause as follows:

case "abc100def"
when /\d+/ => pos
  p pos   # => 3
...

However, Matz didn’t agree with him since the semantics is not
intuitively appropriate.
Keiju Ishitsuka also proposed another extensions which allow us
to use block-like expression in case-expression as follows:

case {|v| v == x }
when v1
  ...

for x case v == x
when v1
  ...

The above expression is almost equivalent to the following expression:

f = proc{|v| v == x}
case
when f.call(v1)
  ...

We can obtain a result of comparison using this idea:

case {|v| $result = (v == x)}
when v1
  ...

Matz was being positive about this idea.

[ruby-dev:17633] rdtool (the newest ruby documents)

Wakou Aoyama proposed that we had better automatically generating ruby’s
documentations using RD.

[ruby-dev:17662] update irb to cvs repository

Ishitsuka Keiju announced that he would update irb in the official CVS
repository.

Did you check RDoc? It’s awesome.

There was a talk of bundling rdtool and Matz wrote that he would use
RWiki to manage documentations before the above proposal.
I think that important point in his idea is to use something like
RD for automatically generating ruby’s documentations, since it is
a little difficult to manage sources and documentations separately.
There is no english manual of ruby-1.6 now.

Thanks. Yes, It’s good, too. I hope bundled tools for RD.

(c.f. rdtool support for manual page.)

Ah OK. Dave, will RDoc feature man page output?

That’s what I thought; perhaps you want to try RDoc and see if it fits
your bill even better for that task.
