Review Request: KDE Observatory (new plasmoid)

[Sandro Andrade]

Summary:

Plasmoid for visualizing development activities in KDE projects. The
motivation comes from the (now inactive) KDE Commit-Digest web site
and the KDE Observatory aims at provide such information as up-to-date
as possible in the plasma desktop. The designed architecture uses two
main components for accomplishing this task: collector and views. A
collector is responsible for acquiring data from a specific data
source, such as lists.kde.org or ebn.org, and storing such information
in a sqlite database. A view provides a visual representation of
collected data. The plasmoid's configuration options allow for the
specification of the watched projects (by means of their commit path
and Krazy report path), selection of which projects should be depicted
in each view, and some parameters for timers, view transition effects,
and the extent of days to be analysed in commit history.

Implemented features:

- Commit Collector (acquiring data from lists.kde.org) - with incremental update
- Krazy Collector (acquiring data from www.englishbreakfastnetwork.org)
- "Top Active Projects" view (more committed projects)
- "Top Developers" view (more active developers - in terms of commits #)
- "Commit History" view (graph showing commit # evolution through the
specified commit extent)
- "Krazy Report" view (showing a per project and per file type Krazy
information)
- Timed transition of views
- Slide effect for view transition

How to use it:

1) Add the plasmoid (plasmoid name = plasma_applet_kdeobservatory)
2) Open configurations
3) The page "Projects" exhibits all created projects. By clicking the
"Add" button a new project can be created (some pre-fabs would be good
here - Plasma, Amarok, etc). Each project has a name, a commit subject
(prefix used in subject field of lists.kde.org?l=kde-commits), a Krazy
report path (http://www.englishbreakfastnetwork.org/krazy/reports/<krazy-report-path>/index.html),
and an icon.
4) The page "Views" shows the enabled projects in each view (Top
Active Projects, Top Developers, Commit History, and Krazy Report). By
default, new created projects are enabled in all views.
5) The page "General" provides configuration for the commit extent to
be collected in lists.kde.org (be prepared for longer acquisition time
when using higher values - limited to 30 days), the synchronization
delay, some parameters for view transition, and a general
enabling/disabling/re-ordering of all projects in a view.

The Commit History view depends on Qwt (yes, I'm still changing
CMakeLists.txt :).

Thanks for any feedback,
