GSoC Meetings
== The Karma Project ==
 
Karma is a framework for creating educational software using JavaScript, html5, and SVG. The Karma team is primarily focused on developing Sugar activities but you can also Karma to create lessons that run in any web browser that supports html5. The best ways to get involved are to join the [http://groups.google.com/group/karmajs mailing list] and [http://git.olenepal.org/karma/karma get the code]
=== Rationale ===
=== Status ===
Karma is a sub-project of Sugar Labs that is under active development as a part of a [[Karma#GSoC_Project| Google Summer of Code project]]. The latest examples can be seen at [http://karma.sugarlabs.org http://karma.sugarlabs.org]. You can also check out the [http://karmaproject.wordpress.com Karma Project blog] for updates.
To try out the karma examples you need to have an html5-capable browser. The Browse activity within Sugar does not currently support html5. To try out karma within Sugar you need to install [http://dev.laptop.org/~bobbyp/surf/Surf-106.xo Surf] and its webkit dependencies or run Firefox 3.5 from the command-line (yum install pywebkitgtk WebKit-gtk gnome-python2-gconf).
The current focus of development is to convert Nepal's set of lessons coded in Squeak smalltalk. You can find the list of lessons to be converted [http://spreadsheets.google.com/pub?key=tweUJyn1BkEciHqVtSvCYDA&output=html here]. This is a good place for new contributors to get started
=== What Karma Is ===
=== What Karma Isn't ===
* Karma is not compatible with Internet Explorer because Internet Explorer does not support html5 apis such as canvas, svg, localStorage, etc.
* Karma is not meant to replace pyGTK as the dominant toolset for creating Sugar activities
* Karma is not a tool for creating activities with complex 3D graphics. Karma is a tool for creating activities with simple 2D graphics
* Unobtrusive JavaScript
* No globals
* No extension of native objects extension
=== Technical Architecture ===
* Run-time - Karma will work with basic functionality on any W3C standards-compliant browser that supports HTML5 tags canvas , audio, and audiosvg. This notably excludes Microsoft's Internet Explorer. Karma will be particularly tailored to work within with Sugar's [[Browse]] activityJournal and collaboration through Telepathy. Longer-term we hope to extend Karma to take advantage of Sugar's collaboration features.* Primary Programming language - Javascript ([https://developer.mozilla.org/Enen/JavaScript New_in_JavaScript_1.6 Javascript 1.8.16]) Karma depends heavily the javascript library jQuery, version 1.3.
* [[Karma/i18n|i18n]] -- Pervasive internationalization is a critical part of Karma
** Supported types of i18n -- ToDo
*** Output of Native Digits
*** Image switching per locale
* Moodle Integration -- method to be determined
* [[Karma/Bundle_layout|Repo and Bundle layout]]
* UI Widgets
** [[Scoreboard]]
** Dialog -- use standard jQuery UI one?
=== Conventions ===
* The [[Karma/Dictionary|Karma Dictionary]]
* [[Karma/Specifications|Karma Specifications]] (early draft)
* [[Karma/Anti-conventions|Anti-Conventions]] -- coding no-nos* [[Karma/Layout_Converted_Squeak_Lessons|Layout for converted Squeak Lessons]]* Source Code stored in http://git.sugarlabsolenepal.org/projectskarma/karma* Working demos at Each lesson must be in a folder named according to the schema "karma_Grade_Maths_title_WeekNo" where the week number is optional The following are valid names karma_3_Maths_LargestNumber_15 karma_2_English_MatchingPuzzle karma_6_Maths_AddingUpTo10_4* Version Control and repository management see the [[Karma#Version_Control|Version Control]] section of this page* Unit testing is required for the karma.js library but not for individual lessons http://karma.sugarlabs.org/tests/
* Project Documentation kept in the Sugar Labs wiki
* Coding conventions: Based in on [http://www.gnudojotoolkit.org/prepdeveloper/standards/standards.html GNU standardsStyleGuide Dojo Style Guide] ** Use camel-case sadCamelCase for function names and variables
** Exception to above -- object constructors should start with a capital letter
** Set column-width to 79 characters (from Python standard practice)boolean variables should be prefixed with "is", "has", "can", or "should"** counters should be prefixed with "num" or "count"** Whenever possible, use [http://www.jslint and then teach the rest of us how** Anything Doug Crockford advises in "JavaScript: The Good Parts".com/ jslint]
* File naming conventions: lowercase letters, underscore instead of spaces (need to write more about it)
* Coding Pattern - We generally try to follow this coding pattern as it makes it easier to browse your code
Put code in following order
1) variable declarations
2) method declarations
3) method calls
 
== Version Control ==
Currently all lessons are stored in the examples/ folder of [http://git.olenepal.org/karma/karma main karma repository]
 
== GSoC Project ==<strike>Here is how you can use the karma_lesson template to create a new repository from scratch  $ git clone git://git.sugarlabs.org/karma_lesson/mainline.git $ mkdir ../karma_3_English_3 # create a new lesson directory following our naming convention $ cp -r * ../karma_3_English_3 $ cd ../karma_3_English_3 $ rm -r .git # make sure you get rid of the old git directory $ git init $ git add . $ git commit -a -m "first commit"
=== Team === Now go to the http://git.sugarlabs.org/projects/new, make sure you are logged inCreate a new project, use the same name as you did for your lesson's main folderthen, $ git remote add origin git://... # the pubic push url
Felipe Lopez Toledo "SubZero" is creating a prototype for Karma as a Google Summer of Code project. [[USER:BryanWB| Bryan Berry]] is serving as his mentor. [[User:ChristophD| Christoph Derndorfer]] is working Then on the draft specification.to coding your lesson ;)
=== [[KarmaFrom then on $ git push origin master # will sync your local tree w/To-Do|To-Do]] ===the server
=== Project Requirements ==='''Tagging''' -- a karma lesson can be in only one of two states, stable or unstable. Any commit tagged 'stable' is the stable version of your code. Every other version of your code is unstable. We will not use numeric versioning such as 0.1, 1.0, 1.2, etc. for the foreseeable future.</strike>
* Create a single prototype activity which could be used as a template for sugarizing AJAX activities. The GSoC participant should not create her own activity but recreate an existing activity such as one of [http://www.pustakalaya.org/external-content/static/epaath/E-Paath-2.activity/activity/Activity/MenuStage.html OLE Nepal's flash activities]. == Meetings ==* This prototype should have the following features:** Simple interactive animation and audio using html5 tags like <canvas> and <audio>** An [[Karma/Assessment| assessment:Meeting 21 December 2009]] section that stores results of student's progress and gives them suggestions on improvement. Assessment info should be persistent. ** Uses simple html for the activity lesson plan and teacher notes.** Integrates with the Journal** Navigation and Help elements, ideally reusing widgets from [http://www.jquery.com jQuery]** Some element of collaboration using Telepathy (This could be really hard, depending on the state of javascript bindings to dbus)
=== Meetings =GSoC Project ==
# Regular meeting between Felpe Karma started as a GSoC project with Felipe Lopez Toledo "SubZero" as the student participant and [[USER:BryanWB| Bryan every Tuesday 0215 UTC at #sugar on ircBerry]] as mentor.freenode.net# General GSOC meeting for participants from Sugar every Tuesday 1400 UTC #sugar-meeting
