Hi Frank,
You are passing a table to editor:ReplaceSel(); I did a little test:
editor:ReplaceSel ({'one','two'})
and the selection disappears. So you would have to make your table
into a string using table.concat(buf,'\n').
BTW, removing stuff using your method should work:
for i = 1,#t do
if t[i] == '' then
table.remove(t,i)
end
end
t = {'one','','two','three'}
for i,v in pairs(t) do print(i,v) end
gives us what one would expect.
