It appears that the Perl that comes with Novell Webserver 3 is some
version 5 (of ambiguous revision level). The more widely available

You might find the section in perlfaq5 entitled
" How do I change one line in a file/delete a line in a file/insert a
line in the middle of a file/append to the beginning of a file?"
enlightening.
If you have the "standard" binary distribution for Win32 (assuming you
post from the same machine you use perl on) and can run perl from the
command line then you can use:
perldoc perlfaq5
to access this most excellent piece of documentation.

That is a vague question, with many different answers, depending

thanks, Bob. so, I just copy the *.pm files to the directory they belong to
(e.g. perl\lib\net)?
just wonder why the faq and readme don't mention this approach. I feel this way
-- downloading the modules, unzipping them with Winzip or whatever, and copying
module files to their directories -- is much easier than using cpan.pm which the
faq claims is easiest (probably true for UNIX systems).

Maybe. If the module contains any XS components, this approach won't
work.
Better to unpack the module distribution, then, from inside the
resulting directory run:
perl Makefile.PL
make test
make install
Better still, is to run:
perl -MCPAN -eshell
to download, build, and install your module interactively.
Hope this is helpful.

What you really want to do is :
perl -MCPAN -e shell
Or try:
perldoc CPAN
to find more information.
Examining the CPAN.pm file with an editor would reveal the
documentation, however, whether perldoc works or not. For myself I
actually find it quite wierd that people dont look at program source
more often - especially in Perl where there is so much of it. (Hey,
I've learned programming languages, after a fashion admittedly, by
reading source code.) Perhaps this lack of curiosity lies at the root
of some of the symptoms we are seeing in c.l.p.m.
You can find both tar and gzip out there for Windows (djgpp & cygwin32
ports are available and possibly more). Alternatively WinZip which is
a widely available piece of shareware will deal with these and various
other formats.
If you have the "standard" distribution for win32 then you will also
have "dmake". Once you have unpacked a module you can run through the
standard build procedure i.e.
perl Makefile.PL
dmake
dmake test
dmake install
You may find it far easier if you have a unix-like shell and
associated utilities. (I guess I lay myself open to charges of being
a unix zealot but - ) I have been finding myself advocating the
cygwin32 port of the GNU utilities and shell quite a lot recently -
but again you can look at:
http://www.cygnus.com
(On NT the Resource Kit gives you enough shell stuff to be going on
with - just enough..)

I haven't tried this on any other versions of perl (or operating systems: this

Subject: Lexers / tokenizers in Perl
Message-Id: <6hbdnm$6nt$1@monet.op.net>
Keywords: intimidate Lawson Mephistopheles scrawny
It used to be that if someone asked me I there was any kind of
programming that Perl was not good for, I would say that it was not
very good for writing lexers. That was because the way I was used to
writing lexers was to process the input a character at a time with a
state machine, and in Perl, that approach is rather slow.
This, of course, does not show that Perl is bad for writing lexers.
It just shows that this is the wrong approach to use when writing a
lexer in Perl. I discovered over time that Perl is an *incredibly
good* language for writing lexers, if you use the right techniques.
My Perl Line of the Day page usually discusses some interesting or
charming trviality. Today, however, it demonstrates an extremely
powerful technique for writing good lexers in Perl. It shows a
complete lexer for a calculator program. The lexer is one line long.

Subject: Losing track of STDOUT after open(FOO, "| program") -- normal?
Message-Id: <6hbenj$mi3$1@ucan.foad.org>
This seems to me like it should be apparent but I'm not finding an
answer I'm sure I'm grokking to the fullest... doubtless it is all
explained in gory detail and I've missed where (I've checked the
perl FAQ, done a dejanews search, and looked in the man page for
perlipc).
I'm finding it to be the case that, while STDOUT is the default
at the beginning of a script, following something like:
open(FOO, "| /bin/program -flags $input") || die "No go pal $!\n";
that if I do not explicitly open STDOUT again, any print statements
for example (like to report completion of the script) do not go to
STDOUT... instead they appear to go nowhere. (Yes, I have closed FOO)
I did find the following paragraph in the perlipc man page:
Both the main process and the child process share the same
STDIN, STDOUT and STDERR filehandles. If both processes
try to access them at once, strange things can happen.
You may want to close or reopen the filehandles for the
child. You can get around this by opening your pipe with
open(), but on some systems this means that the child
process cannot outlive the parent.
It seems this would be the cause of the behaviour I'm finding -- is
my understanding correct? Is the behaviour I'm describing totally
normal, or am I (most likely) missing something? I'm not looking to
reopen the filehandle for the child process /bin/program, I'm looking
to print to STDOUT for the benefit of Joe Luser running the script from
the shell.
If the paragraph above from the perlipc man page is the reason for
the behaviour I'm seeing, where should I look for style pointers to
find a good way around this? Is opening STDOUT explicitly in order to
print a script is done message really what I ought to do? It seems...
crufty to me. This doesn't seem to be exactly the kind of style
issue addressed by man perlstyle either, as far as I can see.
My goofball script works -- I just feel sure that what I've done to
get it to go is kludgy and unattractive (namely explicitly opening
STDOUT to write a message to Joe User's screen saying "You're done.").
Pointers to existing documentation which I may have missed will be
welcomed with relish.

Are you execing any processes ? Are you certain that this isn't really
buffering of STDOUT ? ( try setting $| ).

Strange things would happen with STDOUT if one of the processes alters the
terminal state, turning off echo for example, or repositioning the cursors eg.
Plain text output should not cause a problem.

You might just check out the recurring threads on comp.lang.c on the

They seem to get almost if not more zealously eclectic (?!!) about

Message-Id: <35395371.6AD10639@series2000.com>
Question: Has anyone tried playing with the netscape
source code (to include any perl interface/mod)?
Gripe follows:

This would be fine if those people not willing to put the effort
into answering a newbie's question would refrain from putting
the effort into roasting said newbie over "flames". It would
make for a much more respectable newsgroup and would
probably bring the SNR higher.
Analogy: We have a "road rage" problem here in VaBch.
Seems that if people respect the speed limit during rush
hour, they get cut off/tailgated/blinded/honked at/and worse.
This includes the cars with those big yellow signs on top
which read "student drivers".
Suggested rule of thumb: If the question is below your
ability, ignore it and let someone else respond to it. (That
is, unless someone is paying you to respond to ALL of
the posts in c.l.p.m.)

Not interested in the Gripe, I'll skip it; but,
I have been banging on Netscape 5.0 Source
and I would say that a lot of it is missing.
I cannot get it to compile. I have the Unix version.
All 85MB of it :-)

You don't have motif do you ? You need it to compile 'mozilla'.
The source released on the first day compiles out the tar ball without
modification on Solaris with CDE as it includes motif includes and libs.

I'm sure Sam got helped a lot with that answer. If you think Sam
should use something else than the diamond operator and not use
the manual, please post your suggestion.

I think a comp.lang.perl.help newsgroup would be a good thing. I
remember, several years ago, reading a lot of gnu.emacs.help, and it
was very, um, helpful.
So, we could have:
comp.lang.perl.help - for people needing and giving help,
comp.lang.perl.moderated - the "wizards" group, if you will, and
comp.lang.perl.misc - for perl issues and philosophy.
Just a thought.

I like the idea of comp.lang.perl.help, as for .moderated ... I'd
hold off on that until traffic patterns determined if it were necessary.

My preference is simply to add c.l.p.moderated. Those who don't like
the influx of people with less than ideal attitudes towards Perl,
programming, learning, life, or whatever could hang out in this
moderated group, where the others' posts would be rejected.
Others could come to c.l.p.misc, which could encompass the ".help"
function as well as what it's currently being used for.

All messages issued by Perl are explained in the 'perldiag'
man page that is included with the perl distribution.
Checking there will often help when perl says something that
makes you say "huh?".
( "chunk 1" means while reading line 1 of STDIN, unless you've
messed with the $/ special variable (INPUT_RECORD_SEPARATOR in 'perlvar').
)

I see from your other post that the thirteenth looksee did the trick ;-)

: Can anyone shed some light on this?
Compilers report the line number where they _recognized_ that there
was a problem. Sometimes they don't notice that anything is wrong
until several (or many) lines beyond where the mistake really is.
If you were following directions to London, you might not realize
you made a mistake until you were in Wales. All you can say is:
"recognized that I made a mistake when in Wales"
Can't tell where the mistake was made, other than somewhere before
you got to Wales ;-)
This happens with all programming languages, it is not specific to perl.

Administrivia:
The Perl-Users Digest is a retransmission of the USENET newsgroup
comp.lang.perl.misc. For subscription or unsubscription requests, send
the single line:
subscribe perl-users
or:
unsubscribe perl-users
to almanac@ruby.oce.orst.edu.
To submit articles to comp.lang.perl.misc (and this Digest), send your
article to perl-users@ruby.oce.orst.edu.
To submit articles to comp.lang.perl.announce, send your article to
clpa@perl.com.
To request back copies (available for a week or so), send your request
to almanac@ruby.oce.orst.edu with the command "send perl-users x.y",
where x is the volume number and y is the issue number.
The Meta-FAQ, an article containing information about the FAQ, is
available by requesting "send perl-users meta-faq". The real FAQ, as it
appeared last in the newsgroup, can be retrieved with the request "send
perl-users FAQ". Due to their sizes, neither the Meta-FAQ nor the FAQ
are included in the digest.
The "mini-FAQ", which is an updated version of the Meta-FAQ, is
available by requesting "send perl-users mini-faq". It appears twice
weekly in the group, but is not distributed in the digest.
For other requests pertaining to the digest, send mail to
