RE: [libreoffice-users] I want to add formulas and functions to calc

There should be care in naming extensions and avoiding collisions with OpenFormula and other 
extensions (implementation- or user-defined).

It might be good to review the specification of OpenFormula in ODF 1.2 for all of the functions 
defined there.  There may be OpenFormula functions of interest that are not yet implemented in 
LibreOffice Calc and it would, in those cases, be useful to implement them as part of the full set.

Also, there needs to be agreement on how extensions not provided for in ODF are identified.  I 
recommend against using org.openoffice simply because there would need to be some sort of joint 
arrangement to manage that as a shared namespace.  Not a bad idea, but absent that it might be 
useful that one use a unique name prefix for LO-defined extensions (as opposed to user-defined 
functions).

This is all to avoid collision of names among implementations when LibreOffice Calc documents are 
interchanged with other ODF-supporting spreadsheet implementations. For user-defined extensions, 
one might want to have a naming policy so those extensions don't collide as well.

Make an Extension and put into the Extensions Repository.

http://www.libreoffice.org/features/extensions/
http://extensions-test.libreoffice.org/

If you do not know how to create an extension and if you do not want
to learn it (which isn´t difficult), you could post the Code and a
description of your new function and hope that some other old man
will pick it up and create and publish it as an extension.
