Perfect IOhannes!
It works! Thanks for the explanation.
Let me finish the patch and I will post it here with a better description of the problems and solutions.
All the best

Dear List,
I am trying to write a txt with pdlua (using pdluax) in a Mac (yosemite) Everything is clear but I can't solve a permission error:
lua: error in dispatcher: [string "txtwrite.pd_luax"]:11: example.txt: Permission denied
that should be unrelated to pdlua.
the problem is, that you do not really know *where* on the filesystem you are writing the file. contrary to what you might expect (e.g. besides the "problem.pd" patch), a simple call to
open()(and lua's io.open() is just a thing wrapper around the underlying C-function) will create a file in the working directory of the calling application - which is determined at startup to the place where you started Pd from. since you are on OSX, i assume that you are starting Pd from simply clicking on the application icon, which IIRC uses the filesystem root (/) as your working directory (at least some older versions of Pd, probably including Pd-extended).now in general it's a good thing that you are not allowed to write stuff in
/. the fix is rather easy: provide full pathnames when using low-level file io-functions. for testing it might be a good idea to use a tempdir, e.g. /tmp/example.txtgfdsar IOhannes
