Hi fellow wiki editors!

To help newly registered users get more familiar with the wiki (and maybe older users too) there is now a {{Welcome to the wiki}} template. Have a look at it and feel free to add it to new users discussion pages (and perhaps your own).

I have tried to keep the template short, but meaningful. /Johan G

Howto:Extend Nasal

Wrapping Classes as Nasal Objects (ghosts)
For the time being, it's a good idea to take a look at the FGPositioned wrappers for the navdb to see how this is done in Nasal, see [https://gitorious.org/fg/flightgear/blobs/next/src/Scripting/NasalPositioned.cxx $FG_SRC/Scripting/NasalPositioned.cxx].
There's a plan to eventually unify all those helpers and provide them as part of the FGNasalSys class(or some custom abstract base class that C++ classes should implement to expose objects to Nasal), so that they automatically become available to all users of the Nasal subsystem.
