Question:

Perl CkByteData and CkZip

Sep 09 '16 at 13:25

I'm trying to generate a zip file entirely in memory, but I am struggling with understanding how to interface CkByteData. Perl makes us lazy, so we don't think much about data types.

Can someone offer feedback on what I'm doing wrong in this example:

#!/usr/bin/perl

use chilkat;

my $zip = new chilkat::CkZip();
$zip->UnlockComponent("XXXXXXXXX");

my $dataobj = new chilkat::CkByteData();
$dataobj->appendStr("TEST ZIP TEXT");

my $success = $zip->NewZip("test.txt.zip");
if ($success != 1) { print $zip->lastErrorText()."\n"; exit; }

my $success = $zip->AppendData("test.txt",$dataobj);
if ($success != 1) { print $zip->lastErrorText()."\n"; exit; }

my $zipdataobj = new chilkat::CkByteData();
my $success = $zip->WriteToMemory($zipdataobj);
if ($success != 1) { print $zip->lastErrorText()."\n"; exit; }

open(FILE,">test.zip");
print FILE $zipdataobj->getData();
close(FILE);

Answer

Don't forget that AppendData returns a CkZipEntry object, not a success/failure indicator.

Otherwise you pretty much have it. I would wonder if you're opening the output file in binary or text mode. Given that I work in many different programmming languages, it's something I always would question, would never remember, and would always have to lookup..

Here's an example I wrote just now that will get linked from the refdocs and example-code.com shortly..
