[JASS] giving jass variables lua variable values?

[gorillabull]

can you give a jass variable a lua variable value? say you are generating a bunch of destructables and you want to assign their rawcodes to a jass variable

You mean the Object Merger?

Generate the code by lua and import it.

haha good idea

It's infact the only possibility besides transforming your script by another language. Jass is interpreted only by the game and has no compile-time functions that would allow you to read files or run other programs. vJass on the other side provides directives like //! import and //! external. Latter is very slow though and you have to consider that //! import is handled before //! external, so you cannot effectively generate jass scripts by an external lua program and import it within the same save call. Your lua program could however modify your .j file itself or run jasshelper anew.

I do it the way that I have redirected the save function of JNGP starting my own executable instead of jasshelper. Then I run various tools that alternate my .j and other files and merge it with data outside of the map file. And finally parsers like jasshelper get called to verify the outcome.
