[Libreoffice] Expending LO Math capabilities

Hi

Actually I think (after doing the patch) that such extensions should be
more easily handled by macros.

On a side note: Have you get to now dmath?
http://www.dmaths.org/documentation/doku.php?id=presentation:en

In any case, here is a fragment of a very simple macro that allow you to
append whatever you want into a formula:


+++++++++++++++

Sub MacroMath

GlobalScope.BasicLibraries.LoadLibrary("Tools")

Dim oDocument as object

oDocument = ThisComponent

'test if the document is a math document (OpenDocument Formula)
If getDocumentType(oDocument) <> "smath" then
   msgbox " The document is not a ODF formula"
   Stop
EndIf

oWhatIHave = oDocument.Formula

myExpression = "forall <?> in <?>, exists <?> in <?> divides f(<?>) +
g(<?>) leslant <?>, <?> in <?>"

oDocument.Formula = oWhatIHave & myExpression

' bla bla bla
End Sub

+++++++++++++++

Add a nice dialog to get some input parameters and a lot of clumsy math
expressions could be added very quickly.

Regards

Olivier
