Ohayou GNOME. Weekly Report 4 : GSOC

20th June 2011 : During the fourth week of gsoc I worked on following :

• Core Python Plugin : My mentor Bruno's commit to GCompris added Core Python Plugin support.So now it enables a multi python dir path which can be useful in init_path.sh to pass several directory, one with a plugin engine and one derivative.So now I may use it in all my activities that are importing BrailleChar module by simply modifying the path seperated by ":".Code for multi python plugin.
  

  
  # Set the different path for this activity
  # This is sourced by runit.sh
  pythonplugindir=$path/../braille_alphabets-activity:$path/../dicey_dicey-activity
  



• Braille Math Symbols :
To my surprise I discovered that "...braille is not a language, it's just another way to read and write English--or any other language, such as Japanese,Spanish,German etc".And it became a bit tedious task to look over braille codes for different languages.I did a lot of research over it and finally jumped over :
Louis Braille School :It is approved by the Washington State Board of Education as a private school for children who are blind or partially sighted.
Libbraille : A tool which was originally created to test libbraille and gnome-braille unicode Braille transcription features and international Braille alphabets. It is a Free Software and Open Source.So I have decided upon the braille codes for operators as described below.

Sign    Braille cell 
'+'     3,4,6
'-'     3,6
'*'     1,6
'/'     3,4



• Python Style Guide : It was fun to read coding conventions for the python code and applying the same to my code."A Foolish Consistency is the Hobgoblin of Little Minds" True it is readability counts.Check this out : http://www.python.org/dev/peps/pep-0008/


• Refinement of Dicey Dicey Activity :This week work lead to almost completion of braille deciphering dicey dicey activity. Fixing out bugs, daily commits to make it better, introducing the shuffling concept to all set of questions, rework to have a better distribution of set of lists,braille math symbols, documenting the XML file,etc.Check the code here


• Rhymes_Riddles : I have started with my third activity rhymes_riddles and introduced brain teasers in it.A set of riddles are put up for answering, braille code for correct answer is given in form of a clue.Kids need to read a riddle and decode the braille code.Check the code here.
  And I have overcome those tedious git problems and permissions finally,learnt from the mistake I used to make each time earlier; so happy:)

It's a great summer./ME Happy coding:-)
