I just completed my lua interpreter called GOMPIE. I use it for a faster debugging cycle. If you like it leave a message so I know people are interested.
The last 3 days the only bugs I've been able to find were in the examples and not in gompie, but this is still alpha quality, so if you find any bugs, post them on gta forums. Or better yet, post a fix there, source is included
All info on usage is in the readme.
BTW: I included scripthook, I know it's not allowed but compilation will fail if the project structure is not correct. So if it's really not allowed I will reupload it without source .
