| − | '''DescendantsLines''' is an in-development plugin for Gramps which generates a graphical descendants tree using orthogonal edges.
| |
| − | | |
| − | == History ==
| |
| − | 2007: Adam Sampson has written a standalone python script for parsing data.gramps ([[GRAMPS XML]]). [http://offog.org/darcs/misccode/familytree]
| |
| − | | |
| − | 2010: this script needs some updates for avoiding minor issues.
| |
| − | | |
| − | A modified script is available on the addons repository. [http://gramps-addons.svn.sourceforge.net/viewvc/gramps-addons/trunk/contrib/DescendantsLines/ft.py]
| |
| − | | |
| − | === Limitations ===
| |
| − | The code ignores role on event (was added in 2007).
| |
| − | | |
| − | == 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_development|Addons]] repository as '''unstable''' (beta). [http://gramps-addons.svn.sourceforge.net/viewvc/gramps-addons/trunk/contrib/DescendantsLines]
| |
| − | | |
| − | 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 for generating 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''
| |
| − | # Clean-up - ''in progress''
| |
| − | | |
| − | * simple Gramps XML template with events, persons, families objects (only export primary event role reference).
| |
| − | * 'localized' dates (does not follow last DTD, which uses english and ISO format)
| |
| − | * a basic descendant families textual print for draw reports: this avoids empty returns when generating reports.
| |
| − | ''TODO'': need to fix duplicated families on generated XML file. - ''done'' - next revision
| |
| − | fams = self.database.get_family_handles()
| |
| − | for child in ind_list:
| |
| − | person = self.database.get_person_from_handle(child)
| |
| − | # only family where person is the children
| |
| − | for handle in person.get_parent_family_handle_list():
| |
| − | fam = self.database.get_family_from_handle(handle)
| |
| − | if handle in fams:
| |
| − | self.write_xml_family(fam)
| |
| − | fams.remove(handle)
| |
| − | | |
| − | '''FINISHED''' - it works fine!
| |
| − | | |
| − | ==== Pass 2: use draw report environment ====
| |
| − | | |
| − | # Move Gtk code to draw report (if possible)
| |
| − | # Move cairo code to draw report (if possible)
| |
| − | # Output path
| |
| − | # Clean-up, pylint, etc ...
