Synchronize local and remote directory trees by uploading newer or missing files to the remote server.

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

ssh = Chilkat::CkSsh.new()

# Hostname may be an IP address or hostname:
hostname = "www.some-ssh-server.com"
port = 22

# Connect to an SSH server:
success = ssh.Connect(hostname,port)
if (success != true)
    print ssh.lastErrorText() + "\n";
    exit
end

# Wait a max of 5 seconds when reading responses..
ssh.put_IdleTimeoutMs(5000)

# Authenticate using login/password:
success = ssh.AuthenticatePw("myLogin","myPassword")
if (success != true)
    print ssh.lastErrorText() + "\n";
    exit
end

# Once the SSH object is connected and authenticated, we use it
# in our SCP object.
scp = Chilkat::CkScp.new()

success = scp.UseSsh(ssh)
if (success != true)
    print scp.lastErrorText() + "\n";

# The remoteRoot is relative to the HOME directory of the SSH user account.
remoteRoot = "workspace/projectB"

# Upload synchronization modes:
# mode=0: Upload all files
# mode=1: Upload all files that do not exist on the FTP server.
# mode=2: Upload newer or non-existant files.
# mode=3: Upload only newer files.  If a file does not already exist on the FTP server, it is not uploaded.
# mode=4: transfer missing files or files with size differences.
# mode=5: same as mode 4, but also newer files.

# Additional files and directores can be excluded by setting the SyncMustNotMatch property.
# The SyncMustNotMatch patterns apply only to the final filename or directory part of a path.
# If a directory matches, then it will not be traversed in a recursive traversal.
# 
scp.put_SyncMustNotMatch("*.o;*.obj;*.log; temp")

# The SyncMustMatch property can be set to restrict the files uploaded to only those
# matching at least one pattern in a set.
scp.put_SyncMustMatch("*.cpp; *.h")

# Do the recursive sync to upload newer or non-existant files:
bRecurse = true
mode = 2
success = scp.SyncTreeUpload(localRoot,remoteRoot,mode,bRecurse)
if (success != true)
    print scp.lastErrorText() + "\n";
    exit
end

# The files actually uploaded can be examined in the SyncedFiles property.
# It is a string property that contains the relative path, one per line, of each
# file uploaded.
print "Files uploaded: " + "\n";
print scp.syncedFiles() + "\n";

print "----" + "\n";
