| I'm trying to insert a string that I need to adjust before entering.
%1 is amulet aardwolf |
t = {}
table.insert(t, "string.gsub("%1","( +)|","")")
I get error
[string "Trigger: "]:2: ')' expected near 'amulet'
I read lue table details and help for lua tables and searched forum...
When I do it this way
%1 is amulet aardwolf |
aaa = string.gsub("%1","( +)|","")
t = {}
table.insert(t, "aaa")
it works. But I don't want to use another variable and I think it must work the first way... somehow | Top |

That is a bad reason.
Anyway, in your first attempt you should change
table.insert(t, "string.gsub("%1","( +)|","")")
to
table.insert(t, string.gsub("%1","( +)|",""))
Also, your second attempt doesn't actually work.
You want
not

| here is what i get if I omit the quotes
table.insert(t, string.gsub("%1","( +)|",""))
Run-time error
World: Aardwolf
Immediate execution
[string "Trigger: "]:6: bad argument #2 to 'insert' (number expected, got string)
stack traceback:

I played with all sorts of quotes and didn't get the result.. :(
You are right with the second part
is correct and works. | Top |

Ah...of course. Sorry, I wasn't thinking. gsub returns multiple values. So you can't directly pass it to table.insert. What the second one is doing is implicitly dropping the second return value from gsub. |

| What's your regexp doing? You can't use the "|" in Lua regexps (unless you are looking for "|"). In PCRE regexeps the "|" symbol means "or".
foo = "amulet aardwolf"
t = {}
table.insert(t, (string.gsub(foo," +"," ")))
require "tprint"
tprint (t)
That example removes the spaces in foo. The brackets around string.gsub forces the return of the first result only.
[EDIT] Ah I see now. Try this:
foo = "amulet aardwolf |"
t = {}
table.insert(t, (string.gsub(foo," +|","")))
tprint (t)
Replace foo by "%1" and it should work, eg.
t = {}
table.insert(t, (string.gsub("%1"," +|","")))
