import_view() - getting VE.Top is not defined error

[mesurinna]

Expected behavior

On window.beforeUnload i save all data in the SessionStorage with export_view(). If i import then on page reload all data is shown correctly with the import_view() method. But when i want to use the terminal i am getting an JS Error VE.Top is not defined?

what did i missed?

This is my Code where i initialize the terminal:

`

   $('.terminal_demo').terminal(

        function(command) {
            if (command !== '') {
				$(".cmdInput").val(command);
				$(".cmdInput").change();
				this.pause();    				
            }
        }, {
            greetings: 'Terminal Emulator Demo',
            import_history: true,
            name: 'js_demo',	        
            prompt: '> '
	    }
    );

    if (sessionStorage.getItem(rootFormName + " ." + str_class[0]) != null) {
    var restoreData = JSON.parse(sessionStorage.getItem(rootFormName + " ." + str_class[0]));
    $('.terminal_demo').terminal().import_view(restoreData);
}   

`

The problem is that export_view data is not suitable to JSON.stringify because it have interpreter Stack Structure with functions, so if you export view with nested interpreter you will get the same interpreter.

I can make it ignore interpreters if it's not Stack object.

Also lines have finalize functions but they will just be ignored by JSON.stringify

Saving data without JSON.stingify in sessionStorage and wihtout JSON.parse to read is resulting in another JS Error Ae.Push is not a function.

How can i save these data and reload them on a page refresh?

[mesurinna]

can i just echo out the data exported by export_view()? Just want to reload just all stuff happened before.

In devel branch you now can restore view from JSON but you will not get restored:

• if you echo function (like default greetings)
• if you echo with finalize (you will not have some data on your commands like a11y attributes or command class)
• stack of interpreters (if you call push it will not be restored)
