i'm trying to figure out the best way to organize library functions. i would like to have one object per lib, named the same as the lib. for instance, date functions could be accessed through the xdate object (table?). x - to signify that its a lua extension. this would result in the f-date library functions being reorganized as such -

xdate.format_nn
xdate.timestamp
xdate.datestamp
xdate.datetimestamp

any ideas?

got it

xdate = {}
function xdate.format_nn(n)
local r=tostring(n)
if n<10 then
r= "0" .. n
end
return r
end

http://www.lua.org/manual/5.1/manual.html#5.3 describes the standard way to do this.

ah yes, the module functions.

the manual doesn't help me make any sense of it but i've found a page that appears to help quite a bit.

i'll attempt to module-ize and report back.

It's possible that it's currently broken in CHDK lua, I haven't actually tested it.
