Hi Lutz,

Should this happen?

Perhpas its just a little too nested?

newLISP v.9.0 on Linux, execute 'newlisp -h' for more info.

> (select D (index true? (map directory? (setq D (directory)))))

Segmentation fault

just an addon...

The above was on my path by creating the smalest directory selection from a bunch of files.. So if the above doesn't work then i guess this is

the smallest a "directory filter" can get in newlisp ->

(and (setq X (index true? (map directory? (setq D (directory))))) (select D X))

The first definition crashes because D is modified by 'setq' while beeing used by 'select'.

Also using 'select' with an index list constructed using 'index' is the same as using 'filter', so why not just doing?

Code Select Expand
(filter directory? (directory))

or if you want all files not a directory:

Code Select Expand
(clean directory? (directory))
