Zugg Software :: View topic - Howto: passing a stringlist to a Lua function

What is the best way for passing a stringlist\database record to a Lua function? Say, for a list of 500 entries?
The obvious way is #FORALL @stringList {#LUA {luaFunc(%i)}}
What other ways are and what about their efficiency?

Depends how you're storing stuff and why - if you're going to be using Lua, it might be more sensible to use a Lua table and not use a stringlist at all.

It is a stringlist used in trigger pattern, so it will be CMUD variable 100%. And the function is in Lua. I can feed it with values one after another with #FORALL (current implementation) or move this work inside that or another Lua function (how? And is the result worth all the efforts?)

Can't you just use zs.var.varname?

You can refer to that stringlist and use it in a function easily.

Example, I have a stringlist of like 600 city enemies.

If I want to print them all, I could just do:

Yes, I can. I haven't thought of this way.

And what if there are several variables with the same name but in the different classes? How zs.var will distinguish them?

You know, that's a good point - I don't think it's possible to go down the tree from a class to its contents, only up the tree from the contents to the class. You can ascertain which variable you've got by looking at its class property, which is the class object of its parent class. But if it turns out you have the wrong one, I don't think there's any way to make Lua look for the other variable instead.

This should do what you want. zs.var["ClassName/VarName"]

Edit: I checked, the above will work.
