[iterate-devel] iterate shadows CL:COUNT (bug report)
by mandeep singh 03 Jul '07

03 Jul '07

For example: (iter (for i in '(1 2 3 4)) (for c = (count i (list 234 234 2))) (collect c)) fails because CL:COUNT is shadowed by iterate and so i cant call the function from that scope. A workaround is: (iter (for i in '(1 2 3 4)) (for c = (funcall #'cl:count i (list 234 234 2))) (collect c)) But it is not nice to use this work-around. regards, msingh.

[iterate-devel] Trouble using iterate (ASDF issues ?)
by Olivier Drolet 02 Jul '07

02 Jul '07

Greetings all, I can't seem to get iterate to work. After configuring my init file, and using the relevant ASDF commands, I've successfully installed, loaded, and used libraries like cl-ppcre, but iterate fails to work. My setup is Mac OS X 10.4.10 on PPC G5 running: - Aquamacs 1.0b (Emacs 22.1) - Slime 2.0 - SBCL 1.0.2 I read the [iterate-devel] list and found someone who had a similar problem: > -------------------------------------------------- > [iterate-devel] Problem with new iterate install > > Phil pbpublist at comcast.net > Sat Mar 18 16:17:42 EST 2006 > > Previous message: [iterate-devel] Count is a CL function > Next message: [iterate-devel] Problem with new iterate install > Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] > > > I am attempting to get iterate (1.4 from common-lisp.net page) going > and could use some help.
