=== Write Turtle Blocks in Turtle Blocks ===
+
== Sugar Core ==
  
−
In support of making Sugar as transparent and fungible as possible, we'd like to make it not just Free, but provide affordances for end-user modifications. Turtle Blocks is a possible stepping stone towards that end: a programming environment approachable by children as young as five-years old. So as a first step, let's write Turtle Blocks in Turtle Blocks. From that experience, we'll hopefully know how to approach the more general Sugar problem.

=== Sugar Framework for writing activity in full HTML5 ===

[[File:Sugarhtml5.png|300px]]
 +
 
 +
The objective is to develop a JavaScript framework allowing to write Sugar activities in full HTML5/JavaScript. The framework will expose to JavaScript an API to call Sugar features:
 +
* Journal/Datastore,
 +
* Collaboration/Telepathy,
 +
* Toolbar handling,
 +
* Sugar look&feel - for example via a CSS style sheet usable on HTML controls
 +
* Access to Sugar settings (buddy name, colors, current language, ...),
 +
* View source.
 +
Like PhoneGap/Cordova, the framework will come with a template to develop and package easily a new HTML5 activity. A basic tutorial will be include too.
 +
The work could be inspired by the work done with Enyo Framework in [http://booki.flossmanuals.net/make-your-own-sugar-activities/_draft/_v/1.0/developing-sugar-activities-using-html5/ 1]. By the way, the resulting framework should be JavaScript framework agnostic (no need for jQuery, Enyo, ...).

=== Project sharing website ===
 +
 
 +
Create a Project Hosting Site similar to the Scratch website where kids can share the projects they have created using various Sugar Activities.  The site should foster collaboration and sharing of projects.  The Web Site should be built using a free web framework so that it can be installed at deployment sites. Some features include:
 +
 
 +
* Ability to engage and connect with friends and classmates using various  Social Networking sites/techniques.
 +
* Ability to post projects from various Sugar Activities (ex: Turtle Blocks, Etoys, Memorize, Physics, etc.)
 +
* Separate landing pages for different audiences (kids, teachers, parents, etc.)
 +
* Section to share kid created art from projects
 +
* Ability for users to create galleries (of their own projects, favorite projects, subject specific topics, etc.)
 +
* Ability to have “private classroom spaces”
 +
* Tools to support community management of the site
 +
* Multi-language support

Working with the maintainer of [[Activities/Portfolio|Portfolio]] to add a mechanism for exporting .ogv (voice over still images) of a portfolio presentation. This is a request that has come from deployments: they'd like to be able to post videos of student work, which is currently available as a slide show with audio voice-over.

=== Implement help mechanism for activities using Mallard ===
  
−
A working knowlewdge of Python and some gstreamer skills are a must.
+
[http://projectmallard.org/ Mallard] is a mark-up language that makes it easy to provide user help. It would be a nice feature to add Mallard-like help to activities, accessed through a mechanism similar to the view source mechanism. We need to sort through two issues: integration into Sugar and integration into our i18n / L10n system.

Rather than viewing the details of a Journal entry on a separate page, the idea is to make the details appear in an expandabe in-line format on the main Journal view. The look and feel would be more like Google+ or Facebook. Performance will be a major challenge.

=== Social Sugar ===
 +
 
 +
Design and Develop GUI components that can help Sugar to reflect user's social interactions from external platforms. A perfect target can be the Group-View that shows user's friends and their shared activities [[Human Interface Guidelines/The Laptop Experience/Zoom Metaphor#Groups]], but it _could_ also show social information about these friends, IE social networks or sharing platforms publications. This would also give this zoom-level added value.

=== Plugin support ===

Community members are already working on the backend component to support this feature [http://lists.sugarlabs.org/archive/sugar-devel/2013-March/042055.html]. This is also a great opportunity to complement other GSoC-2013 proposals.
  
−
A number of activities, notably [[Activities/TurtleArt#Plugins|Turtle Art]], are supporting plugins -- the ability to extend features by downloading additional modules. However, [[Activities/TurtleArt#How_to_install_a_plugin|the mechanism for installing plugins]] is anything but friendly. It would be nice to design a uniform plugin bundle type and modify the activity installer to recognize this new type. Caveats include dependencies -- presumably the plugin would take care of that -- and version control -- plugins are often incumbent upon a specific version of an activity. [http://activities.sugarlabs.org ASLO hosting]] should also be considered.

=== End-user modifications of Sugar source ===
+
Wiki: [[Summer of Code/2013/Social Sugar project]]
  
−
We have an existing mechanism for duplicating and modifying Sugar activities: a copy of the bundle can be creaed in ~/Activities, where it can be modified by the end user. We also have a mechanism for viewing the Sugar toolkit source, but no such convenient way for making changes without risking messing up the system. While it should be easy enough to make a duplicate copy in the user's home directory, and to change the Python paths to use the modified code, we need some mechanism -- presumably at boot -- to choose which version to run: the installed version or the modified version.

A goal of Turtle Blocks is not just to get children programming, but to launch them out of block world into text-based languages where they can develop more sophisticated programs. While Turtle Blocks is written in Python and can be extended by importing Python modules, it currently exports only in its native block language and in Logo. For this project, we'd want to enable a Python export option so that programmers can take their Turtle projects and extend them into full-fledged Python projects. The hypothesis is that this would lead more children to grow their programming skills beyond simple block programs.
