I know this has been asked before... Own Function Libraries...

[Void Singer]

pretty sure the basic answer was covered in post 2 by Crystal (no, it must be done manually)

 

PS.
there is no way to "quietly" push new scripts/functions/libraries to customers withing lsl, since the functions that deliver and replace scripts must be owned by the same owner.... that means at the very least a new object that updaates the old one, either directly, or by complete replacment of the object in question.

Ahh I missed Crystal's reply for some reason and yes, I'm very much aware of the lack of "quiet"-ness. Just seemed to me, like so many posts in this forum and many others, that it had traveled in a direction not in keeping with the OP. But hey, just recently came back to SL after an absence and felt like diving back in

It would certainly be nice to have some form of pre-processor directives and most certainly a versioning system added into it as well. Something like:

#include my_library.lsl

or even...

#include-latest my_library.lsl

and have it compare the script's version number so you could automatically push the latest version at compile time and even force a recompile at run-time if required.
