Learning by doing... Non working example!
local Lines={}
repeat
local Line=Handle:read('*line') --> bug local Line
Line=Line and string.gsub(Line,'\r','')
if Line==nil or Line=='' then
-- process lines here; e.g. with iterator
Lines={}
else
table.insert(Lines,Line)
end
until Line==nil --> Line is ever nil

And in my newer example also the declaration of Line needs to be moved
outside the loop. After all the working example:
local Lines,Line = {}
repeat
Line=Handle:read('*line')
Line=Line and string.gsub(Line,'\r','')
if Line==nil or Line=='' then
-- process lines here; e.g. with iterator
Lines={}
else
table.insert(Lines,Line)
end
until Line==nil
I am a programmer since ~20years now but sometimes I fall back to a
newbie ;-)
