Merging of events in people with supertool

[Woody]

Hi,

I’m currently creating a family history book based on a village. I’ve already merged several individuals.

As a result, I naturally have many duplicate entries in the events section. I’d like to somehow consolidate these. Here’s an example:

The profession “Master Baker” appears three times, each with a different date.

Kari @kku , could this be combined using a Supertool script?

So, if the type, description, and location of the event are the same, and only the date and source differ, the date should, of course, be expanded to a range (from-to), and the source should be added to the others.

Could you please help me with a script again?

OS: Win 64, Gramps AIO64-6.0.8–1

Thank you in advance.

Here is another extreme example.

I can try to make such a script.

In the meantime you may take a look at the README.md before installing this addon: gramps/addons/events_and_citations at master · kkujansuu/gramps · GitHub

With it you can manually merge a person’s events by dragging them in the gramplet window (e.g. in bottombar). It also supports merging date ranges.

But if you have a large number of such people then a script would be more suitable.

Hi Kari,

I wasn’t familiar with this Gramplet.I never stop learning with Gramps.

But there are mutch more than 1000 people. That’s why I’m asking if Supertool can handle that. I would have processed 100 people manually or with the Gramplet you just discovered.

Try this script. The file merge-events.py is in the next message.
