I'd like to make some associative tables e.g. table={x=7,y=90,z=40}
but I want to save tokens by using a string because I'm going to have a lot of them, and make a function that returns a table based on whatever is in the string.
So something like:
string1="x=7,y=90,z=40" string2="empty=100, dinner=casserole, transport=horse, weight=150" table1=assoc_table(string1) table2=assoc_table(string2) ?table1.z -- 40 ?table2.transport -- horse |
how do I go about this? split wont work. what does my function assoc_table(str) look like?

There are many options, but I use HTBL().

string1=htbl"x=7;y=90;z=40;" string2=htbl"empty=100; dinner=casserole; transport=horse; weight=150;" |
You can also define global variables collectively by using CAT() to join _ENVtables.

cat(_ENV,htbl[[
string1{x=7;y=90;z=40;}
string2{empty=100; dinner=casserole; transport=horse; weight=150;}
]]) |

you are right, split is the correct starting point - idea is to use 2 split!
— split each key/value
local tmp=split(“x=7,foo=bar”)
local out={}
for kv in all(tmp) do
— split a pair + extract table values with unpack
local k,v=unpack(split(kv,”=“))
out[k]=v
end |
