I tried replacing my io.read() with your io.lines() construct, but
because the
if statements are still not working for me mine is still not
detecting the "&"
Here is my program as it currently stands:
#! /usr/local/bin/lua
-- Read fortunes in
do
local aline
jar = {}
pointer = 0
cookie = 1
for aline in io.lines() do
jar[cookie .. "+" .. pointer] = aline
pointer = pointer + 1
print(">" .. string.sub(aline,1,2) .. "< " .. cookie .. "
" .. pointer)
if ( string.sub(aline,1,2) == "&&") then
break
end
if ( string.sub(aline,1,1) == "&") then
pointer = 0
cookie = cookie + 1
end
end
print(pointer .. " " .. cookie)
end
This incorporates your change, but cookie still increments for me,
and pointer is
never re-zeroed, In your example none of your if statements had a
finishing end,
am I doing that wrong??
do I need to do
if (condition) then do
statement
statement
end
I am trying that with the code but it is confusing me....
