Hi all
Just a quick thought.
I looked into offline editing and found this setup. I installed the Eclipse Developement platform and added the extra Java JDK to my runtime tools. Eclipse allows you to configure 'perspectives' including LSL specific plugins. This will allow you to not only edit, but with this you can compile, optimise, test and run all your scripting. Setting the software up is a little bit tricky, but all the answers are in the readme files and help sections within eclipse and the components archive.
Here are the LsL Plus Compiler components.
There are further tools within this development platform, specifically the Glasgow Haskell Compiler (GHC) version 6.10.1 or later. You can find all you need to know in the LSL Plus help section within eclipse.
It's then just a simple matter of cut 'n' paste your scripts in and out of SL. Simples.
I hope this is useful.
