@walter Thanks walter for the clarification. Source file can be viewed directly from pippy and user can add their tools from there. No need of copy-to-jornal now. @Benjamin Thanks Benjamin for the guidelines. Will help me alot. I''ll try to implement same by both the methods.(pippy one and Benjamin's approach). Now, we need to provide user a simple interface to upload the code. Is their any way that in paint activity only, a tab(button) should be inserted which when clicked will take user directly to desenho.py (inside pippy activity)...such that user will simply add his/her tool(code) over their. Guide me if i am wrong. (I am new to sugar actually,that why clearing my concepts here). Thanks a lot for your help.

I think that's a great idea, and it should not be too hard to implement. You will need to provide a GUI for editing, but this is easy with gtksourceview. You also need a way to save and load the user's code. If you are targeting Sugar 0.84+, then the easiest way to do this is to add the programmable tools to the datastore object's metadata as a string. See, for example, <a href="http://wiki.laptop.org/go/Sugar.activity.activity#How_do_I_implement_a_write_file_method_for_my_activity_in_order_to_persist_my_activity_in_the_journal.3F" target="_blank">http://wiki.laptop.org/go/Sugar.activity.activity#How_do_I_implement_a_write_file_method_for_my_activity_in_order_to_persist_my_activity_in_the_journal.3F</a> This method is very easy to use (probably one or two lines of code) and has the advantages that (1) it only creates a single Journal entry, and (2) the Journal entry it creates is still a standard PNG file, so it retains excellent compatibility. However, this method will only work reliably on Sugar 0.84 and newer. --Ben </blockquote></div>
