If opt are Lua strings and :match is the standard string.match,
perhaps what he meant, instead of ,円 was to use %, which is the escape
character for Lua patterns. However, since both "-" in the beginning
of a pattern and "-" in the end of a group carry no special meaning,
the correct code would probably be this:
for i, opt in ipairs(arg) do
local token = opt:match("-+([a-z-]+)")
Unless he means to match strings containing actual backslashes, then
the code would have to look like this:
for i, opt in ipairs(arg) do
local token = opt:match("\\%-+([a-z\\-]+)")
