Dear List,
Hello,
In the following function defined in Fontsampler for quick overview
of all fonts in a directory hierarchy, I need the output to be sorted
alphabetically. How can I do that?
function dirtree(dir)
assert(dir and dir ~= "", "directory parameter is missing or empty")
if string.sub(dir, -1) == "/" then
dir=string.sub(dir, 1, -2)
end
local function yieldtree(dir)
for entry in lfs.dir(dir) do
if not entry:match("^%.") then
entry=dir.."/"..entry
if not lfs.isdir(entry) then
coroutine.yield(entry,lfs.attributes(entry))
end
if lfs.isdir(entry) then
yieldtree(entry)
end
end
end
end
return coroutine.wrap(function() yieldtree(dir) end)
end
Any help would be gratefully appreciated.
Thanks,
Mingranina
