Finished: Gramps 4.0

Gramps was originally written as a GTK application intended to only be used in a graphical environment. Over time, support has been added for other user interfaces (CLI and web). In order to reduce unnecessary dependencies between the various interfaces, the software architecture is being organized into 5 main categories of code - each in their own directory.

The descriptions below provide the general purpose and scope of each category.

src/gen/

This directory contains the core components of Gramps. The src/gen/ directory shall not have any dependencies on the other top level source directories (src/gui/, src/cli/, src/webapp/, etc). The src/gen/ directory also shall not have any dependencies on the gtk library.

The word "gen" was chosen because it is short for "general" and "generic" which is a good way to describe code in this directory because it doesn't depend on or require a specific user interface. "gen" is also short for "genealogy" which is also an appropriate term for the code in this directory because it implements the "business logic" that makes Gramps a genealogy application.

src/gen/datehandler/

The datehandler directory contains the code for handling dates in different locales.

src/gen/db/

The db directory contains the code for manipulating the Gramps database.

src/gen/display/

The display directory contains business logic for displaying database objects in textual form. For example, localized date display and name display code.

src/gen/filters/

The filters directory contains the code for filtering objects.

src/gen/filters/rules

The rules directory contains the code for rules used by the filters. The rules are divided into sub-directories according to primary object type:

  • src/gen/filters/rules/citation
  • src/gen/filters/rules/event
  • src/gen/filters/rules/family
  • src/gen/filters/rules/media
  • src/gen/filters/rules/note
  • src/gen/filters/rules/person
  • src/gen/filters/rules/place
  • src/gen/filters/rules/repository
  • src/gen/filters/rules/source

src/gen/lib/

The lib directory contains the classes for the database objects.

src/gen/merge/

The merge directory contains the classes for merging database objects.

src/gen/mime/

src/gui/plug/report

This directory has the dialogs for running reports, such as selection criteria, file pickers, and paper sizes.

src/gui/selectors/

This directory contains the code for the object selection dialogs in the GUI.
