Extracting full trigger code from map

Basically i am done with trying to fiddle with gui functions. Its simply too damn slow and inefficient.

How do i get the full trigger script text out of my map for external editing?

Select trigger... edit > convert to custom text

or eventually if you want WHOLE map script
open map with winmpq
extract file war3map.j (or something .j)
modify it
import it back

Do i import it back with the normal import file interface, or via mpq archiver?

Doesn't matter I think, but I can be wrong ;/

You can use JSP, http://wc3campaigns.com/showthread.php?t=78566

Use normal import
