gnu readline ruby vs. perl
Wybo Dekker
action. I made two, hopefully equivalent, test scripts in Perl and Ruby,
but they behave differently.
Here's my Perl script:
#!/usr/bin/perl
use Term::ReadLine;
# count lines in stdin (the mail message):
$n=0; while (<>) { $n++ }
print "$n lines\n";
my $term=new Term::ReadLine 'vpp';
$term->readline("type return to quit: ")
And here the test run:
$ echo test |readlineperl
1 lines
type return to quit:
$
Now the Ruby version:
#!/usr/bin/env ruby
require 'readline'
include Readline
# count lines in stdin (the mail message):
n=0; while gets: n+=1 end
puts "#{n} lines"
readline("type return to quit: ")
Its test run does not exit with a return - it needs ctrl-C:
$ echo test |readlineruby
1 lines
type return to quit:
./readlineruby:10:in `readline': Interrupt
from ./readlineruby:10
$
Is this a bug? Or a missing feature, like Readline.new?

Ruby's readline takes input from stdin. Perhaps Perls takes from
/dev/tty, or something. Any information is welcome.

The test exited immediately after printing the prompt, on my box.
What are your platform, ruby and readline versions?

I've experienced same problem with OP.
$ ldd /usr/lib/ruby/1.8/i686-linux/readline.so | grep readline
libreadline.so.4 => /lib/libreadline.so.4 (0xb7f00000)
$ ruby -v
ruby 1.8.2 (2004-12-25) [i686-linux]
Same on the 1.9 (March).

I had the same, both on ruby 1.8 and 1.9, but with libreadline.so.5

This was on cygwin.

Same on linux.
Seems depending on readline implementation.

Ugh... probably because they were "overwritten" by the mis-numbered
articles.
Hopefully someone has backups... I imagine they are rather
historically important...

I should have backups of all these articles. I can check when I get
home tonight.

Hmm. Now it's got TWO X-Mail-Count headers. That's not good.
Is there a reason for the listserv to preserve existing mail-count
headers?

Possibly... it looks like the listserv doesn't strip existing
X-Mail-Counts, though it puts them second.

If anyone needs them to do the restore, I'll .zip them up and send them
to you.
