GSoC/2013/Activity Help
Introduction
This page contains information about the project "Implement help mechanism for activities using Mallard". This project is being implemented as a GSoC 2013 project.
Although the initial proposal was to use Mallard for the help mechanism, the research done and the progress of the project proved that simply using the current help content would serve the purpose. Therefore with the approval of the mentors, the implementation with Mallard is dropped.
Objectives
- Implement a help mechanism to view Help in the Activity
- Support l10n for help content
- Write help for more activities
- Improve current Help Activity
Progress
View help for the Activity in the help itself
Help content for the current Activity can be viewed in the Activity itself. It will pop up in a window when the user enters the key combination ctrl+shift+h. If there is no help content for the Activity, an error message will be written to the log. I have used the bundle_id of the Activity to match it with the corresponding help content file (in html).
ActivityHelp in Browse
ActivityHelp in Pippy
Support help content localization
For the help content I have generated the POT files using sphinx internationalization tools. The POT files are submitted to help_content project in Pootle with the emmense support of Chris. The help content is being translated.

Update Help Activity
Help Activity was improved to so as to support localized help content. Before localization content is supported, Help Activity was released with the help content in the form of html files, static content including images, css, javascript etc. With localized help content, there will be one set of static content and different html files for each and every language that help content is localized into. I have done mainly two modifications.

helplink file
helplink is a json file. It includes the bundle_id of the Activity and the name of the corresponding help content (html) file. This file will be used when viewing help content in the Activity. Following is the current version of helplink.json.
{
"org.laptop.sugar.ReadActivity": "read.html",
"org.laptop.WebActivity": "browse.html",
"org.laptop.Chat": "chat.html",
"org.laptop.Calculate": "calculate.html",
"org.eq.FotoToon": "fototoon.html",
"org.laptop.RecordActivity": "record.html",
"org.laptop.MeasureActivity": "measure.html",
"org.laptop.Oficina": "paint.html",
"org.sugarlabs.PortfolioActivity": "portfolio.html",
"org.laptop.Memorize": "memorize.html",
"org.laptop.Terminal": "terminal.html",
"org.laptop.AbiWordActivity": "write.html",
"org.laptop.TurtleArtActivity": "turtleart.html",
"org.laptop.Pippy": "pippy.html",
"org.laptop.TamTamMini": "tamtammini.html"
}
directory structure modification
To support localized content I had to change the directory structure of the help directory of the Help Activity. Following is the directory structure before,
help -_images -_static -*.html (help content)
new directory structure (with localization support) - only localization of English and Sinhala are shown as en example
help -_images -_static -en -*.html (help content in English) -si -*.html (help content in Sinhala)
l10n_script.sh
l10n_script.sh is a bash script develop to ease the process of bundling all localized help content to be shipped with Help Activity. In Help Activity, all the help content are in help directory. This script will generate the localized html content and place them in help directory with the proper directory structure. In releasing a new version of Help Activity, the maintainer can simply copy the help directory to the Help Activity directory, bundle it and ship.
Following is a snap of the directory structure associated with the script
help l10n_script.sh translated_po -si -02_index.po -03_about.po -da -16_sugar_ui.po -en -23_gnome.po
Update current help content
I have been updating the current help content, making them upto date with localization supporting screen capturing (label icons of the screen captures with numbers and refer and describe the icons below in text so that it can be localized). During the review process of submitting help content to Pootle, a lot of improvements with regard to the language are being done.
To-do
- Write help for activities
- Update current help content for some Activities including FotoToon and Record
