(Lianja) SFTP Sync Download Tree w/ Must-Match Filename Constraints

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

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

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

loSftp = createobject("CkSFtp")

llSuccess = loSftp.Connect("my-ssh-server.com",22)
if (llSuccess = .T.) then
    llSuccess = loSftp.AuthenticatePw("mySshLogin","mySshPassword")
endif

if (llSuccess = .T.) then
    llSuccess = loSftp.InitializeSftp()
endif

if (llSuccess <> .T.) then
    ? loSftp.LastErrorText
    release loSftp
    return
endif

// 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.

// This example will download all files, but only those files having filenames
// that match *.gif and *.eml

// 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/

// Indicate that we only want to create auto-create local directories (if needed)
// for the files that are actually downloaded.  If SyncCreateAllLocalDirs remains
// .T., then the corresponding local directory is created for each remote directory
// traversed regardless of whether files within are downloaded.
loSftp.SyncCreateAllLocalDirs = .F.

loSftp.SyncMustMatch = "*.eml; *.gif"

lcRemoteDir = "syncDownloadTest/someDir"
lcLocalDir = "qa_output"
lnMode = 0
llRecursive = .T.
llSuccess = loSftp.SyncTreeDownload(lcRemoteDir,lcLocalDir,lnMode,llRecursive)
if (llSuccess <> .T.) then
    ? loSftp.LastErrorText
    release loSftp
    return
endif

// The following files were downloaded:

// chiliPepper.gif
// abc/chiliPepper.gif
// data/chiliPepper.gif
// data/xyz/dkimVerifyTest.eml
// data/xyz/emailForCreateDsn.eml
