Carsten,
Here is a patch for a new 'est+' summary type, including corresponding changes for xemacs and the manual. I've done basic testing on the GNU emacs version, but not the xemacs code.
I'm not sure the change to the manual provides the right amount of information
in the right place; I'd be happy to re-write to make it find in
better. Similarly, the name of the summary type is entirely up to you.
I didn't know whether to send this directly to you, or to the list; if it should go to the list I'd be happy to send it there directly.
Thanks for the chance to contribute,
Mike
This patch makes some straightforward corrections to a number of
docstrings. Each change is normally to:
- correct a typo, or
- fix up hyperlinks to function or variable names, or
- ensure slightly better conformance with the documentation guidelines
and tips given in the Elisp manual
No attempt is made to provide missing docstrings or document arguments.
Cheers,
Phil
If there was a title set for a column, org-agenda-colview-summarize would look
for the title instead of the property, resulting in empty summaries. This is now
fixed.
Make org-agenda-columns-summarize work properly with the new summary types.
It was assuming the values should be summarised by adding them together. It's
now updated to use the summary functions in org-columns-compile-map, and also
handles summary types with calculated values properly.
Leave calculated columns blank if there is no underlying value.
Don't return zero if a property is missing.
Changes are also applied to xemacs colview.
This lets you see how long has passed since the specified timestamp property
each entry. The three operators (@min, @max, @mean) show either the age of the
youngest or oldest entry or the average age of the children.
