DescendantsLines
DescendantsLines is an in-development plugin for Gramps which generates a graphical descendants tree using orthogonal edges and routing ("square edges").

History
2007: Adam Sampson has written a standalone python script for parsing data.gramps (GRAMPS XML). [1]
2010: this script needs some updates for avoiding minor issues.
A modified script is available on the addons repository. [2]
Limitations
- No option for name display
- No quoting of xml-tag-like data. Data which resembles xml syntax may cause error.
- Script ignores role on event (was added in 2007)
- Script ignores localized date handlers (using ISO date format, date quality in english)
- Memory limitation with a large database (DOM parsing)
- The last pixel column of each secondary line of each entry is wrong coloured (red instead black)
Usage
- Copy the files DescendantsLines.py and DescendantsLines.gpr.py from svn to your Gramps plugins directory, in this case $GRAMPSHOME/gramps/gramps33/plugins .
- Create the directory $GRAMPSHOME/gramps/gramps33/plugins/DescendantsLines/ .
- Open Gramps and generate the report -- Reports -> Graphical Reports -> Descendants Lines. Choose the output path. This output path will contain an empty file after the report is run.
- Look at the file $GRAMPSHOME/DescendantsLines.png. That's the real output. The path for the output is hardcoded.
- Rename the file DescendantsLines.png to something else or remove it in order to run the plugin again.
Example
- Image:Charlemagne-DescendantsLines.png -- A family tree of Charlemagne starting from Chloderic King of Cologne. (No preview, click on "Full resolution")
Descendants Lines
There is an experimental try for migrating this Gtk/cairo code to a draw plugin working into Gramps (font, style, path, canvas, output formats).
Draft version is available on Addons repository as unstable (beta). [3]
The idea will be to keep the Gramps XML parsing, but with a copy of the active database and use of current report environment (output formats, style, path).
Needs
Pass 1: generate a tmp XML with only data needed for the report, to load it as input
- Enable Person selection (Gramps ID) - done
- Generate a temp Gramps XML database matching 'IsDescendantFamilyOf' filter rule - done
- Input path - done (need to set @prefix@: path_to_SVN/src on const.py)
- Clean-up - done
- simple Gramps XML template with events, persons, families objects (only export primary event role reference).
- key/filter issues remain, currently export all persons to XML file.
- 'localized' dates (does not follow last DTD, which uses english and ISO format).
- a basic persons list print for draw report: this avoids empty returns when generating the report and could help to check what is missing (see above).
- output path and format are hardcoded: $GRAMPSHOME/DescendantsLines.png .
FINISHED - it works fine!
Pass 2: use draw report environment
- Generate a plugins/docgen/PNGDrawDoc.py file [4]
- Move Gtk code to draw report (if possible)
- Move cairo code to draw report (if possible)
- Output path
- Clean-up, pylint, etc ...
Pass 2 (Alternate): use of user-defined (mega)-widgets
- Have a look at mega-widget request and implementation [5]
- Output path through mega-widget
- Clean-up, pylint, etc ...
Command Line Interface
Gramps provides a cli support for running reports and tools [6].
- use stdin and stdout for command line import/export [7]
