in Lua, how can I use a table as varargs (…)?

Question

strjoin accepts one string and then a variable number of arguments. I\'m looking for a way to take a table with a variable number of arguments and use each item in the table

Answer 1

Use the unpack function:

local myString = strjoin(' ', unpack(myTable))

Newer versions of Lua place the unpack function in the table module:

local myString = strjoin(' ', table.unpack(myTable))

This doesn't answer your question directly, but as lhf pointed out, the following is much more efficient:

local myString = table.concat(myTable, ' ')

Answer 2

Use table.concat instead of strjoin.
