Zugg Software :: View topic - Lua Script in Alias causing illegal token error

Beginner Joined: 15 Apr 2013 Posts: 24

Hello all, wrote a script in luaEdit and then brought it into cmud but I'm unable to get it to run and wonder if anyone has some insight.

The variable holding a string list is defined in cmud.

c = zs.var.c
d = zs.var.d
w = {}
n = 0

for k,v in ipairs(c) do
n=n+1
w[n] = v
end

This code throws an illegal token error on the for k,v line, specifically saying (c) ... if I remove the brackets the error will shift to the n+1 section.

I could easily rewrite this all to zscript, but that wasn't the point, this was an attempt to use the built in lua support.

Any thoughts?

Did you set the language of the script to lua?
Should be a drop down list just to the right of the alias name

Can you print c and see the correct value before doing ipairs?
Have you tried just using pairs?

Yes, I did and could see c correctly ... and d as well. The zs object was alive and well.

I think this may be some sort of UI bug. I changed the language to Lua and then pasted my script into an alias, and it works.

Thanks for trying to help debug this, Now I just need to remember that Lua's 0th element is null in a cmud stringlist and I"ll be ok.
