jed, and I suspect also vi* and the various incarnations of emacs,
also recognizes a pattern which one often embeds in a comment (usually
at the top), like thus
# -*- Perl -*-
I find this feature very useful for modules, although I may set up
another association for '.pm'.

I have version 1.68. It allows me to select and then indent a block of
text using the tab key. I don't know when this feature was introduced.

I use GVim almost exclusiely. I am a wimp. I have only learned a minimal
set of original vi commands.
I am genuinely scared of emacs ;-)

Subject: Read socket using both <> and sysread()
Message-Id: <MPG.1f428e8e79cfda619898ad@news.tiscali.fr>
Hello. In the framework of a dialog with an ESMTP server, I would like
to alternate some incoming socket reading using <> (when server replies
with a single line) and sysread() (when server replies with several
lines), is there something to take care with this kind of alternance ?
Here a piece of typical part (without response codes checking) :
use Socket;
[here code to connect using two sockets : SOCKET_IN and SOCKET_OUT]
select(SOCKET_IN); $| = 1; select(SOCKET_OUT); $| = 1; select(STDOUT);
my $resp = <SOCKET_IN>; # wait server be ready
syswrite(SOCKET_OUT, "EHLO test\cM\cJ", 11); # engage dialog
sysread(SOCKET_IN, $resp, 1024); # fetch a multi-lines response
syswrite(SOCKET_OUT, "AUTH PLAIN\cM\cJ", 11); # engage authentication
$resp = <SOCKET_IN>; # wait server ask for username
[...]

do you know the difference between <> and sysread? the docs or faq
(not sure where ATM) strongly state that you should never mix them on a
single handle unless you are extremely sure of what you are doing. the
problem is that <> uses stdio which will buffer input from the handle
and then return only one line to you. a following sysread won't (or may
not) find any data to read as it was already read into a buffer by
stdio. the best way to do this is to only use sysread and do your own
buffering and then parse out a line from the beginning of the buffer
when you need one. this isn't too hard to do but it does require some
code beyond just a simple sysread call.

Why not just use read() instead of sysread()?

It's not as much a matter of "implementing the new keyword" as much
one of implementing a constructor, which is something you have to do
in C++ too, with the difference that in the former case it can have
any name and is called like a class method while in the latter by
*means* of the new keyword.

no! You don't HAVE to do it in C++... you can make a class without a
constructor. You can still make a new instance with the new keyword
without having written a constructor.

Fair enough. The main point still being that it's not as much a matter
of "implementing the new keyword" as much one of implementing a
constructor.

Yeah... although the main point was really to tell Davy that he shouldn't
expect Perl to be anything like C++ in terms of OO.
