Hello,
Here is a summary of ruby-dev ML from the end of December
to last week.
[ruby-dev:19198, 19277] Ruby 1.8.0 / yield(nil) and yield()
Masatoshi SEKI pointed out that the behavior of yield(nil) has
been changed to the same as yield() in 1.8.0-preview1.
ruby-1.6.8:
def foo(*arg)
yield(*arg)
end
foo() {|*x| p x} # -> []
foo(nil) {|*x| p x} # -> [nil]
foo(1) {|*x| p x} # -> [1]
ruby-1.8.0-preview1:
foo() {|*x| p x} # -> []
foo(nil) {|*x| p x} # -> [], same as foo()
foo(1) {|*x| p x} # -> [1]
Matz changed 1.8.0 sources to work same as 1.6.8. Also he and Tanaka
Akira started discussion for how this behavior should work.
[ruby-dev:19233] [1.8] speed
Forking from [ruby-talk:59980] thread, investigation for memory
allocation and GC performance has been started, based on reports of
[ruby-talk:59662], [ruby-dev:18482] and [ruby-dev:19242]. They found
the problem in details of the current implementation. Some GC
improvement patches were posted.
[ruby-dev:19261] lstripped here-document
Nobu Nakada proposed the idea for a new here-document style inspired by
[ruby-talk:50473]. In his idea, if you assign a character (except
quotes) after the here-document indicator “<<-”, All blanks and
assigned character at the head of each line will be deleted.
Here is a example assigning ‘|’:
p <<-|EOS
> foo
> bar
EOS
# => " foo\n bar\n".
He already posted a patch to add this function. Matz wants any
comments for the idea from all Rubyists.
[ruby-dev:19287] Re: Class.inherited
From [ruby-talk:60377], Matz is considering Class.inherited invocation
timing. He has a plan to change Class.inherited to be invoked after the
class is declared.
[ruby-dev:19331] [Oniguruma] Version 1.5
