Re: [MacPerl] Word Count Programme..

[Andre Leclerc <alecler@cam.org>]

Hi,

You know, reading your code carefully for typos, missing $'s, and so on, is
always a good thing to do before asking for help. :-)

Also, well-formatted code is so much more enjoyable to read and review...

And if you're going to write things like $WordCount = $WordCount + 1, you
might as well be programming in Pascal. Try to "think Perl", it is a cool
language with loads of power.

I thought you might enjoy to see how simple things can be in perlish
(tested for accuracy against the results BBEdit gives).

-------------------
#!/usr/bin/perl -lw

use strict;

my $filename = 'sample.txt';
my ($charcount, $wordcount, $linecount) = (0,0,0);

open(F, $filename)
   or die "Error opening $filename: $!";

use locale;
while (<F>) {
   $charcount += () = /./gs; # newline counts as a character
   $wordcount += () = /\w+/g;
   $linecount++;
}
no locale;

close F;

print "Characters:  $charcount";
print "     Words:  $wordcount";
print "     Lines:  $linecount";
__END__

Good luck,
AndrŽ
