Simple way to Reverse an Array
Bill H
way of reversing the arrays contents?
open(FILE,"sometextfile.txt");
@THETEXTFILE = <FILE>;
close(FILE);
So $THETEXTFILE[0] holds line 1, [1] holds line 2 ect. other than doing
something like this is there a way to reverse the values?
for($i = @THETEXTFILE -1;$i >=0;$i++)
{
$THENEWFILE[@THENEWFILE] = $THETEXTFILE[$i];
}
I am just typing this in, not pasting actual code.

Has been a long time but finally we got a new SAQ (Self Answering Question).
Did you check "perldoc -f reverse"?

You have asked a SAQ: Self-Answering Question

SAQ!!
it deserves to be on this page (author is cc'ed)
http://www.ginini.com/perlsaq.html
try looking up the very word you used to describe the function you want
to perform. search perldoc perlfunc for it.

Your basic question has been answered, but is there any chance you are
actually trying to read the file backwards?

i cc'ed him on my previous post in this thread.
he tends to be slow to respond or update that page. i had to google to
find it and it wasn't even found by google (at least on the front page!)
but several others had links to it. it is always an amusing read!

Actually I am trying to read it backwards so that I can display the
most recent entry first (it is a simple log file). I will look at this
link you sent in more detail.

I'm usually pretty quick actually. Keep in mind that my timezone is GMT-12

Yes, that's what I was talking about. And I can find no mention of
<pre> removing the requirement for escaping entities at
http://www.w3.org/TR/REC-html40/struct/text.html#h-9.3.4

sorry for the slight insult! :) and i see the updated page now. just
curious, but could you put in the date of each entry? then we could
track when SAQ's get created.
and IIRC when i last emailed you an SAQ i noticed your page hasn't been
updated in a while. maybe i was thinking that and it wasn't your
response time. that just means we don't get enough SAQ's here (or
elsewhere)!
and at least i didn't pull out my 3rd grade insult dictionary and abuse
you with that! :)

You are quite correct. It just so happens that all the previous entries
(apart from the two newest) didn't have any filehandles in the code, hence
the reason why I never picked it up until now.
I've now corrected the escaping.

Perl SAQ's tend to come in a group and then go really quiet for a long time.
Expect a couple more in the next few weeks :-)

FWIW, the page displays properly on my systems (Firefox on SuSE and
Windows). I dusted off IE on XP and it looks OK there also.

Are you saying you don't understand that you can read it forwards into
an array and just use the reverse() function to process (ie, display)
it backwards?
Of course, if you REALLY want to read the file backwards, you can use
the File::ReadBackwards module (I'm not making this up - see
http://search.cpan.org/~uri/File-ReadBackwards-1.04/ReadBackwards.pm).
Or, the IO::All module acts as a proxy for File::ReadBackwards, and
IO::All makes your life easy, so it would be as simple as:
#!/usr/bin/perl
use strict; use warnings;
use IO::All;
print io('file.txt') -> backwards -> slurp; # EASY!
__END__
Of course, filehandles, opening & closing, and error handling/reporting
are all provided by the IO::All module.

you find actual abuse contact information?

If '<' and '>' had no special meaning after <pre>, how would the
closing </pre> tag be recognized?

If the log files are large, reading it in small chunks starting from end,
and proceeding towards the top will be more practical.

I think you missed part of my point, and jumped the gun a little here. I
know what File::ReadBackwards does ... Inded, I am the one who first
suggested it in this thread. See:
http://groups.google.com/group/comp.lang.perl.misc/msg/a811a14fbe6e7353
The capitalization in David Filmer's 'REALLY' implied to me that he was
not convinced that it was a good idea to read the log file backwards.
So, I tried to explain to him and others why using your module is a
better idea than
my @log = reverse <$log>;
Hope this clarifies things a little.

and the ironic thing is that i have never actually used this module
myself. i just don't ever seem to need to process logs and other large
files backwards. i wrote it to quiet the constant request for an easy
and fast way to do this. the perl cookbook 1st ed. has an awful solution
of scanning the file forward by lines and storing each line's seek point
in an array and then using that to read backwards by seeking to and
reading a line.
it was also a good exercise in writing a module that was focused on
those two requirements. i think it makes for an interesting piece of
well written code that would be worth reading by anyone into perl. of
course your comments on it are welcome and will be redirected to
/dev/null. :) and it seems to have become the community standard way to
do do this.

Gets confused quite easily with information. Review for Final was a 3
hour session which he emphasized a whole area to memorize only to not
include it in the final at all.
Most retarded teacher at Cornell; he couldn't even solve 2x=12 to
derive the eq. pt.
Unur is useless at life. You do not learn a single thing in this class.
It's a joke.

Cool, but out of topic. <g>
It can be shortened to(o):
| perl -ple 's/.\w+$//;s/(\w+)/reverse$1/eg'

Honestly, over the last 15 years during which I have been teaching in
one capacity or another, I have received both better and worse
evaluations.
I try to give my students the service they deserve for the money they
are spending on their education.
Every time I receive feedback pointing out my shortcomings, I do my best
to improve myself. It is even better if the critcism is accompanied with
suggestions on how things can be improved.

I had such a twist in my first version, and it was indeed nice to repeat
it.

And really, aren't those sites mostly geared toward people with an axe to
grind? At least where I went to university, full polling of all students was
done each semester for each class, and the results were available in the
department office for the last couple of years if you wanted to look. A far
more accurate picture I would think, as the biggest complainers were
probably skipping class that day anyway, hence their inevitable failure...

Breaking my promise immediately ;-)
My department has switched to anonymous online evaluations. These
evaluations are available for a period of about two weeks during the
finals period.
Once we turn in the grades, we receive printouts of everyone's input
(completely anonymized).
And we all get the occasional evaluation filled with profanities. In
fact, one of the evaluations I received last semester contained some
nasty language, but it was not representative.
I think there is a difference in what people say when they have to
actually put their thoughts on paper versus when they are just filling
in a form online.

Hmm, oddly like usenet... ; )
I was actually afraid that a prof would identify my comments by my
handwriting, though (until I learned that the comments were typed up before
being passed on). I actually had one prof look at my final exam in a third
year course and then ask me if I had been in his first year class because he
remembered my handwriting (yes, he explicitly said handwriting!). The
electronic experience does seem to encourage what would otherwise be
considered anti-social behaviour on the part of some people, but maybe we
should leave this topic to the sociologists.

Thanks for exposing our prejudice.
Another array-reversing version:
| perl -aF'(\W)' -ple '$_=reverse reverse splice@F,0,-2'
