[dsdp-tm-dev] RE: Target Management Project - Undergraduate Level thesis to Politecnico di Milano

Hello Francesco,
It's good to hear that you've mastered the RSE Tutorial, and created some sample
WIth respect to the SWT Shell It looks like there is a misunderstanding. In the
context of SWT, a "Shell" is just any root window. This has nothing to do with
the contents of that window, or with what we understand when talking about a
"remote shell" in the sense of a terminal. Read the Javadocs of SWT Shell for
more insight.
Look at what the RSE code does for the action "Launch Shell", see
to understand how to programmatically open a View like the Remote Commands
Don't try to write into / read from an SWT TextArea. Instead of that TextArea,
you'll want to use the widget instead. It's similar to a
TextArea, but it will interpret VT100 terminal commands for you. That's the
whole goal of this project -- getting an SWT View hooked up to RSE, that
interprets Terminal control sequences.
For managing "SSH-Shells and Telnet-Shells", RSE will do it automatically
for you when you work on an IRemoteCmdSubSystem as you've done.
Depending on how the user configured his connection, the IRemoteCmdSubSystem
will actually run on the IShelLService configured by the user.
If you have any more questions, just let me know.

Hello Martin,

after have perused the online documentation "RSE developer Guide", these are the things that I have done until now:

1) I have implemented a new plugin (with relatives classes) with the extensions for subsystem, popmenu and property page.

    Some classes are: that extends "SystemBasePlugin" with methods to manage the file .properties that extends SystemBasePropertyPage with methods to create buttons, textarea or many other components that I'll include it.

       PopupMenu class, that show Terminal in the "IRemoteFile" connections

Now  a new subsystem doesn't appear yet in the connections for a generic  "Remote Systems View" but my "Raw Terminal" (for now) starts from the choice in the "IRemoteFile" popupmenu (method run(IAction action)  in the PopupMenu class).

2)I have used the "packages" and "org.eclipse.rse.subsystems.shells.core" to manage the commands that the user insert into Terminal and I have created some useful classes about it. In particular to execute a generic command I have used the followed code:

            IRemoteCmdSubSystem cmdss = getRemoteCmdSubSystem(); 

            if (cmdss instanceof IShellServiceSubSystem) {

                IShellService shellService = ((IShellServiceSubSystem) cmdss).getShellService();              
                String[] env=shellService.getHostEnvironment();
                String workDir = selectedFile.getAbsolutePath();
                IHostShell hostShell = shellService.launchShell(workDir, env, new NullProgressMonitor());
                hostShell.addOutputListener(new StdOutOutputListener());   // to get the output command
                hostShell.writeToShell("mem");   // a command for example

    public class StdOutOutputListener implements IHostShellOutputListener {
            public void shellOutputChanged(IHostShellChangeEvent event) {
                IHostOutput[] lines = event.getLines();
                for (int i = 0; i < lines.length; i++) {
                        display.asyncExec (new Runnable () {
                              public void run () {
                                 shell.setTextArea(shellOut+"\n");   // shell is my "SWT Terminal View" with a Text to  show the output command and allow insert command

I have tried to execute a command in a local shell and he works! At this point my question is:

In this way can I execute a generic command in a "generic Remote System View"?

3) After that, in this moment I'm creating the new User Interface Terminal View with SWT libraries. I have created a new SWT shell that extends Shell. For example:

Display display = Display.getDefault();
            ExampleShell shell = new ExampleShell(display, SWT.SHELL_TRIM);
            while (!shell.isDisposed()) {
                if (!display.readAndDispatch())

this shell-window appears when I click "My Terminal Shell" in the IremoteFile popupmenu. But this window isn't in a "tabbed pane" like old classic "Remote Shell". How do i do to show as tabbed windows my Terminal View?

I allow user to insert command and show its output using the same "textArea". I have thought to place the cursor in the "text Area lenght +1" position and forbidden user to edit character before the (textArea lenght +1) position.  When I  read  the  character with keycode=13 it menas that enter button is pressed than I send the new command  to the methods see above and I show relative output.

Furthermore, how I manage "SSH-Shells and Telnet-Shells" services?

For other questions I'll write you.

Thanks and greetings,

Crivelli Francesco
