Subject: [ruby-core:24027] [Bug #1687] ARGF.lineno Always Returns 0 for ARGF.chars and ARGF.bytes

Issue #1687 has been updated by Run Paint Run Run.


Nobu, thanks for looking.

Using the .lines iterator, ARGF.lineno returns the correct line number:

    $ cat argf.rb
    ARGF.lines { |l| p ARGF.lineno }

    $ echo -e "foo\nbar\nglark" >file

    $ ruby argf.rb file
    1
    2
    3

Using the .chars iterator, it always returns 0:

    $ cat argf.rb
    ARGF.chars { |c| p ARGF.lineno }

    $ ruby argf.rb file
    0
    0
    ...
    0
    0

Using .bytes has the same result:

    $ cat argf.rb
    ARGF.bytes { |b| p ARGF.lineno }
    
    $ ruby argf.rb file
    0
    0
    ...
    0
    0

On 1.8, the last two examples always print 1.

Am I missing something obvious here? :-)
