Hello all,
I tried to workout the plugin/ module idea for the application
and I made a version 0.0 with it. The code should show the
setup of the modules, and an example for two modules: the
user interface and the import module.
I have put the source code in separate directories.
Directories:
* datamodel : this contains the internal datastructure for our
genes information. The implementation of the Person
class is only meant as dummy, and should be replaced.
I still don't like my own class names, so if somebody
has better ideas, let me know !
This module does not depend on other modules ...
For the PersonInfoList we should implement the observer
pattern ...
* genesCore : this contains some base classes for the modules +
the application class which glues all modules together
This module only depends on datamodel
* test : this module has an example/test implementation for two
modules.
* glade1 : A first glade based user interface. this directory is
empty, but I will make an implementation which has
the same functionality as the SimpleUI class
* tools : empty: this should contain classes for the widgets
modules
Modules
* Datamodel : we should also split it into a base class and
implementation,
so that another implementation is possible.
(for example for an approach where not all the data is
loaded in memory at the same time)
* Import : Module for reading from xml, database X, database Y,
gedcom, ...
* Export : Module for writing output: database X, flat file,
postscript
file, txt, xml, html...
* UI : user interfaces ...
* Tools : Widgets, algorithms, scripting plugin ?, ...
The idea with user interfaces is that they should not be necessary:
If genes is started without an interface, it can be used for batch
processing, for converting files, ...
Some coding rules I followed:
* Class names start with a capital
* variables start with small character
* members end with an underscore (this improves readability of
sources)
* I used "@TODO" and "@REMARK" marks in the source code.
these strings are normally not used for anything else, and thus,
somebody can easily do a grep on all sources to see the remarks and
todos
Some remarks:
* What is a better name for the GenesInfomodel class name ?
* We should use the "command" pattern for the tools module
* We should use the "observer" pattern for the PersonInfoList class
(if the infoList changes, all subscribed listeners can update
themselves)
* The Makefiles should be reworked
* The module names should be centralized in one include file ...
These are used for retrieving the correct module from the
application
* the Glade userInterface will follow some days after christmas ...

Send me all your comments, ...
Geert
ps Sean,
Can you update the directory structure in CVS and move the files, then I
will
checkin my code ...
