Calling Pattern
Call
local r,c = sl.str.join(a1, a2[, ...])
Args
a1...aN are of any type (converted to strings internally via tostring())
Results
r is a string c is a number
Usage Example
local s = sl.str
local i = 'Bunch '
local r = s.join('Concatenate ', 'A ', i, 'Of ', 'Strings')
print(r)
--> Concatenate A Bunch Of Strings
Description
Joins all string arguments in order and returns the resultant string as well as the number of strings joined.
Upon Error
Join fails silently. If join receives no arguments, then a '' (empty string) is returned. If join receives only one argument, then that value is converted to a string and returned along with the arg count in the result tuple.
