Now added: t:redraw(), see [ltabfill] example.

And it looks like it won't be implemented for the foreseeable future:

"#t does not invoke the __len metamethod when t is a table."
See end of: http://lua-users.org/wiki/GeneralizedPairsAndIpairs

This means pd.Table will remain ugly, with :length() :set() :get(), at 
least until Lua 5.2 (maybe).

Ok, using the Makefile.static you should be able to download two tarballs:

https://devel.goto10.org/dl.php?repname=maximus&path=%2Fpdlua%2F&rev=0&isdir=1
http://www.lua.org/ftp/lua-5.1.3.tar.gz

Unpack pdlua.tar.gz, then put lua-5.1.3.tar.gz directly inside pdlua/

Then edit pdlua/Makefile.static to change the PLATFORM= line to macosx, 
and within pdlua/ run "make -f Makefile.static"

It should compile first Lua then pdlua, and then you can test it with 
"pd -path src/ -lib lua"


Hope this works, let me know if not.
