Installable with the Extension Manager

Description

This extension adds the Google Blockly Template to XWiki, to make programming easier for users who have little/no previous experience of programming, by allowing the creation of Blockly templated documents. Currently, this template provides support for combining the blocks from the default toolbox provided by Google, viewing the source code for the same, editing a document using these blocks and saving it.

Usage

To create a document using the Blockly template, please follow the steps given below:

  1. Make sure you're logged in
  2. Click on create page at the top right corner, and choose the "Blockly" template in the create page document.

    Selecting Blockly editor to edit the page
  3. This should take you to the Blockly template page. Drag and drop the blocks from the toolbox onto the adjacent div and combine them like puzzle pieces, as desired. For example:
    For example:

    Combining blocks appropriately
  4. To delete any of the blocks, drag and drop the blocks into the bin.
  5. To view the source code for the blocks generated in the figure, click on the Source tab.

  6. Save the code using either the "Save and View", or the "Save and Continue" buttons.
  7. If you want to view the code you generated and/or execute it, go to the View Page. It looks like this:

  8. To run the code, click on "Run Code".

Prerequisites & Installation Instructions

We recommend using the Extension Manager to install this extension (Make sure that the text "Installable with the Extension Manager" is displayed at the top right location on this page to know if this extension can be installed with the Extension Manager). Note that installing Extensions when being offline is currently not supported and you'd need to use some complex manual method.

You can also use the following manual method, which is useful if this extension cannot be installed with the Extension Manager or if you're using an old version of XWiki that doesn't have the Extension Manager:

  1. Log in the wiki with a user having Administration rights
  2. Go to the Administration page and select the Import category
  3. Follow the on-screen instructions to upload the downloaded XAR
  4. Click on the uploaded XAR and follow the instructions
  5. You'll also need to install all dependent Extensions that are not already installed in your wiki
