Splits a string using a delimiter
s1, s2, s3 ... sn = strsplit("delimiter", "subject")
Arguments
- (delimiter, subject)
- delimiter
- String - Delimiter
- subject
- String - String to split
Returns
A list of strings. Not a table.
Example
local a, b, c = strsplit(" ", "a b c")
Result
a = "a" b = "b" c = "c"
Details
Again, note that the return from strsplit is a list of values, not a table. To get a table, use e.g.:
local tbl = { strsplit(delimiter, subject) }
Also note that strsplit uses a raw string as delimited, not a pattern, so it's not particularily well-suited for e.g. commandline arguments, where it should be ok to use multiple spaces. To extract whitespace-separated arguments, you can use e.g.
local tbl = {}
for v in string.gmatch(" this has lots of space ", "[^ ]+") do
tinsert(tbl, v)
end
