Re: Tracking Lines Printed to a FileHandle

The more I think about it, the more I think that for most needs it's probably best to just count newline characters immediately prior to printing:

$count += $print_string =~ tr/\n//;
print OUT $print_string;

...why get tricky with something so easy, right?

Yes after looking at the project it was much simpler to just count the newlines before each print, and that is what I wound up doing. Thanks for the suggesstions and help. Here is a sample of what i wound up doing as far as the same FILEHANDLE, different file goes: $filename = "MyJScript01.txt"; push(@filenames,$filename); $filenumber = 1; #variable to track the filenames format: MyJscript#.t +xt where # is a number open (OUT,">$filename"); print OUT "<script language='JavaScript'>\n"; print OUT "function whichMapper(obj){\n"; print OUT "if(obj.selectLSO.selectedIndex == 1){\n"; $lineCounter = 3; #Track the number of newlines printed to the JS file (other code with many prints each line incrementing $linecounter)... if($lineCounter > 1000){ close OUT; $filenumber += 1; $filename = "MyJScript0".$filenumber.".txt"; push(@filenames,$filename); open (OUT,">$filename"); $lineCounter = 0; } } print OUT "}\n"; print OUT "</script>\n"; close OUT; (at the end I do stuff with the files created)... [download] This is a snippet from a larger program, but basically what I was doing was creating a javascript file based on some data in a db. The file was being included into a dynamic webpage. The file apparently got too large an cause a buffer overrun in the include directive of the web server we use. so I just decided to break the file up into smaller files and include them in order. Wound up working fine.	[reply] [d/l]

$filename = "MyJScript01.txt";
push(@filenames,$filename);
$filenumber = 1; #variable to track the filenames format: MyJscript#.t
+xt where # is a number
open (OUT,">$filename");


print OUT "<script language='JavaScript'>\n";
print OUT "function whichMapper(obj){\n";
print OUT "if(obj.selectLSO.selectedIndex == 1){\n";
$lineCounter = 3; #Track the number of newlines printed to the JS file

(other code with many prints each line incrementing $linecounter)...

    if($lineCounter > 1000){
        close OUT;
        $filenumber += 1;
        $filename = "MyJScript0".$filenumber.".txt";
        push(@filenames,$filename);
        open (OUT,">$filename");
        $lineCounter = 0;
    }
    
}

    print OUT "}\n";
    print OUT "</script>\n";
close OUT;
(at the end I do stuff with the files created)...
