Because sometimes a text based interface is more easier to use than a GUI.

With Console you can add a command line interfaces to your web application. Use it for SQL query interface, admin shell, test interface, build integration, etc.

• Supports raw line-based input, predefined commands, and basic control characters.
• Built-in argument parsing. Supports grouping with double quotes.
• Simple command/callback mechanism to quickly add new console commands
• Command history
• Terminal-like scrollable buffer
• Following control characters are supported: BELL (^G), TAB (^I), LINE_FEED (^J) , FORM_FEED (^L), CARRIAGE_RETURN (^M).
• Bash-like command completion using TAB
• Bash-like "visual bell"
• PrintStream implementation for redirecting output to console (even System.out or System.err).
• Custom command prompt and greeting message
• Set size either using width/height or rows/columns
• 'ObjectInspector' helper to expose properties and methods in any Java object to the Console as commands.

Note: Since version 1.1.6 the Console add-on requires Widget RPC add-on.

Sample code

        // Create a console
        final Console console = new Console();

        // Handler for the console
        root.addComponent(console);

        // Size, greeting and other configuration
        console.setPs("}> ");
        console.setCols(68);
        console.setRows(20);
        console.setMaxBufferSize(20);
        console.setGreeting("Welcome to Vaadin console demo.");
        console.reset();
        console.focus();

.term, .term .i {
    background-color: #F5F5F5 !important;
    color: #222222 !important;
}
