do trailing spaces cause (file? x) to return nil?

Post by ghyll »

I have a few directories full of files named with trailing spaces. I thought this would remove the trailing spaces, but it only returns nil.

Code: Select all

(dolist (x (directory path))
        (rename-file x (trim x))
)
I tried debugging by using (trace true) with the following code:

Code: Select all

 (dolist (x (directory path)) 
   (file? x))
)
The "." and ".." files in the directory are files, but the other files return "nil". Does the trailing space prevent newLISP from recognizing the file as a file? Is there something else that may be causing the error (e.g. bad code on my part)? Thanks!

Maybe you overlook that directory only returns file base names, without the path prefix?

D'oh! You're completely correct. I forgot to move Terminal from my "newlisp" directory to where it should have been. Thank you :)
