Gnumeric and Quantlib

[Tuan Nguyen-6]

Hello,

I am new to Quantlib, but I saw that Luigi had done a very primitive port of Quantlib to Gnumeric. I would be interesting in having a look at it to see if we can develop it a bit more.

Is there anybody who has done it already ?

Rgds.

Tuan.

Not a port---it was more in the proof-of-concept league. And it passed  
through the Python bindings for QuantLib and the Python plugin for  
Gnumeric.

I'm attaching the bit I did. It was a long time ago and the library has  
changed, so I guess it won't run any longer. You can have a look  
though, so you can get the idea.

But in my opinion, you should throw away my stuff entirely, use the  
Gnumeric API, and possibly join forces with Nando's QuantLib-XL thing.  
You'll have to go through the same hoops in order to bridge the  
impedence mismatch between an object-oriented library and a function-
oriented spreadsheet module. Maybe you can share a bit of  
infrastructure (such as the ql/functions thing, which doesn't really  
belong to the core library.)

Cheers,
        Luigi

As the gnumeric maintainer I'd love to see someone work on this.
Feel free to send me questions.  If anyone is interested we can
even include the Quantlib Wrapper in gnumeric itself to simplify
maintenance.
