(Perl) FTP Sync Download Tree w/ Must-Match Directory Constraints

Demonstrates how synchronize a directory tree in the download direction, but only entering directories matching a set of wildcard filenames.

Note: This example requires Chilkat v9.5.0.76 or greater.

Chilkat Perl Downloads Perl Module for Windows, MacOS, Linux, Alpine Linux, Solaris

use chilkat();

# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

$ftp = chilkat::CkFtp2->new();

$ftp->put_Hostname("ftp.something.com");
$ftp->put_Username("my_login");
$ftp->put_Password("my_password");

# Connect and login to the FTP server.
$success = $ftp->Connect();
if ($success != 1) {
    print $ftp->lastErrorText() . "\r\n";
    exit;
}

# Set the current remote directory to the root of
# the tree to be downloaded.
$success = $ftp->ChangeRemoteDir("/subDir1");
if ($success != 1) {
    print $ftp->lastErrorText() . "\r\n";
    exit;
}

# Possible synchronization modes are:
# mode=0: Download all files
# mode=1: Download all files that do not exist on the local filesystem.
# mode=2: Download newer or non-existant files.
# mode=3: Download only newer files. If a file does not already exist on the local filesystem, it is not downloaded from the server..
# mode=5: Download only missing files or files with size differences.
# mode=6: Same as mode 5, but also download newer files.

# Imagine our remote directory tree has these files and directories:

# 	accentedLatin1.txt
# 	accentedUtf8.txt
# 	alice.key
# 	anter_cert.pem
# 	chiliPepper.gif
# 	helloWorld.pdf
# 	abc/chiliPepper.gif
# 	abc/ghk/
# 	data/chiliPepper.gif
# 	data/xyz/dkimHtmlBody.txt
# 	data/xyz/dkimVerifyTest.eml
# 	data/xyz/emailForCreateDsn.eml
# 	text/frenchUtf8.txt
# 	text/helloWorld.txt
# 	text/PolishEmailBody.txt
# 	text/something/

# Only enter remote directories named either "data" or matching "x*"
$ftp->put_SyncMustMatchDir("data; x*");
$mode = 0;
$success = $ftp->SyncLocalTree("c:/temp/subDir1",$mode);
if ($success != 1) {
    print $ftp->lastErrorText() . "\r\n";
    exit;
}

$success = $ftp->Disconnect();

# Show the files downloaded.
print $ftp->syncedFiles() . "\r\n";

# Output showing the files downloaded:

# accentedLatin1.txt
# accentedUtf8.txt
# alice.key
# anter_cert.pem
# chiliPepper.gif
# helloWorld.pdf
# data/chiliPepper.gif
# data/xyz/dkimHtmlBody.txt
# data/xyz/dkimVerifyTest.eml
# data/xyz/emailForCreateDsn.eml
