Hi,

once again this special mailing list settings :(
Here my answer to Lucas, now for the list too.

Hello everyone,

I've developed my self a set of functions using visualbasic for Excel
and they do work fine. I've also tried those on LibreCalc (as Macros)
and they also work fine as well.

I was thinking then on porting that code so as to use those functions
as built-in functions within Calc, but, to be honest, I have no clue
on how to do it. I'm not even a great programmer. I have very basic
knowledge on programming.

Please tell more about the functions. What calculate the functions? Who needs them? If they are only useful for a very special purpose, it might be better to write an extension than to put them to core. We have already some extensions, which are delivered together with LibreOffice, and a lot of extensions for download.


So, any instructions would help me out understand which is the right
process on developing some thing new for Libreoffice.


Are those functions defined in ODF1.2 and missing in Calc? Then you can follow the guide http://wiki.services.openoffice.org/wiki/Calc/Implementation/Spreadsheet_Functions

Are those functions defined in regular Excel and not defined in ODF1.2? Then there are only small changes to the guide needed.

In both cases you first need to build LibreOffice.

If those functions are more suitable for an extension, you might get a starting point in http://wiki.services.openoffice.org/wiki/Extensions_development and the LibreOffice SDK will help you with a Developers Guide and examples.

Kind regards
Regina
