By now I've found several ways to add minetest specific custom autocompletion to eclipse.
1. Lua Execution Environment
EEs like described
here are too complicated for me. I don't have the time, nor the know how of doing it.
2. Editor Templates
That would be more my thing because it's entirely based on xml and could be provided pretty easily.
Now, what I'm looking for is a good source for all lua api functions with their parameters to do some jEdit magic and create an all-in-one xml template.
Possible sources I know of:
None of the above has a fixed structure that makes copy'n'paste easy.
Is there another source/list of all lua api functions?
Attached, there is a very alpha example of what a eclipse editor template looks like. It's created of the comments of l_env.h (source nr 1). Problem with this source in general is, that not every function is thoroughly commented (params).
