Subject: [ruby-core:36836] [Ruby 1.9 - Feature #4778] IO#each_chomped


Issue #4778 has been updated by Charles Nutter.


Trivial Ruby impl...

class IO
  def each_chomped
    each {|x| yield x.chomp!}
  end
end

Of course if you don't mind the whole file being read into memory:

io.each.map(&:chomp).each { ...

Might be a way to pipeline that without reading into memory.

Feature #4778: IO#each_chomped

When manipulating text files, mostly, the input record separator(saying "\n") is scrap and will be chomped.

I suggest a method IO#each_chomped directly yielding the record with input record separator chomped.

Laziness is a virtue..
