Widgets Language v7 - nodeGame/nodegame GitHub Wiki

All the text displayed to the user should be parametrized: instead of hardcoding it, make use of the texts object to store all your text strings.

This has the key advantage of enabling the easy replacing of any text with another, without changing the code of the widget.

Defining Default Texts

If you are creating a new widget, define a static texts variable with all the display strings:

/** ### NewWidget.texts
 *
 * Default texts to display
 */
NewWidget.texts = {

    // Variables in here contains display text.
    welcomeMessage: 'Hello!',

    // HTML is supported.
    disconnect: '<span style="color: red">You have been ' +
        '<strong>disconnected</strong>.</span><br>',

    // Parametric text is supported.
    gameMode: function(widget, param) {        
        if (param === 'PRACTICE') {
            return 'You are in practice mode.';
        }
        return 'This is the real game.';
    },

    // More text variables can be added as needed.
};

Getting Default Texts

Use the getText method to access the requested text when your widgets needs it. For instance:

// Inside a method of the NewWidget class.

this.getText('welcomeMessage'); // 'Hello!'

this.getText('disconnect'); // '<span style="color: red">You have been ' +
                            // '<strong>disconnected</strong>.</span><br>'

this.getText('gameMode', 'PRACTICE'); // 'You are in practice mode.'

Overwriting Default Texts

If you need to change the value of any default text, you can use the setText method or initialize the widget with a custom texts property. For instance, this translates your widget in Spanish:

node.widget.append('NewWidget', root, {
    texts: {
        welcomeMessage: 'Hola!',
        disconnect: '<span style="color: red">Usted esta ' +
                    '<strong>desconnectado</strong>.</span><br>',
        gameMode: function(widget, param) {        
            if (param === 'PRACTICE') {
                return 'Usted esta en practice mode.';
            }
            return 'Ya empezamos!';
        }
    }
})
