Comments
Comments start anywhere outside a string with a double hyphen (--). If the text immediately after a
double hyphen (--) is anything other than double left brackets (
[[
), the comment is a short comment,
which continues only until the end of the line. If double left brackets (
[[
) follow the double hyphen (--),
it is a long comment, which continues until the corresponding double right brackets (
]]
) close the
comment. Long comments may continue for several lines and may contain nested
[[
. . .
]]
pairs.
The table below shows how to use code comments.
