Creating arrays in Lua from list returned by gmatch

Question

I am programming in Lua and so far I have this.

S=tostring(M[i].AllSegmentsList)      --it returns "MSH, PID"
for i in string.gmatch(S, ",") do      --I have  ", " as delimiter 
  t= {}        --Now, I want the values returned by delimiter to be added into an array.
end

How can I do that.

Answer 1

Declare the table before, and add the elements in the loop like this:

local t = {}
for i in S:gmatch("([^,%s]+)") do  
    t[#t + 1] = i
end 

The pattern [^,%s]+ matches one or more non-comma, non-space characters.
