[iterate-devel] I have patched iterate to accept keywords as clause heads
by Denis Budyak 13 Nov '08

13 Nov '08

Hi there! It is known that loop macro allows keywords as clause start designators: (loop :for i :from 1 :to 10 :collect i) So do many html generation libs, e.g. cl-who: (:a :href ...) Iterate didn't do that and it caused problems while using iterate in conjunction with other libraries such as cl-utilities which defines collecting and collect macros. I patched iterate so that it can use keywords now: (iter:iter (:for i :from 1 :to 5) (when (oddp i) (:collect i)) (:finally (print "hurray!"))) So one need no more to import any symbols from iterate (maybe except iter itself). I also added test of "iterate with keywords" to a regression test suite. you can find a patch and a new file here. http://paste.lisp.org/display/69869 Discussion (currently empty) can be found here: http://groups.google.com/group/comp.lang.lisp/browse_thread/thread/f252c793… Would iterate developers like to incorporate the changes to the main branch? If not, would you object against creating separate iterate-keywords project on the net? best regards Denis Budyak

[iterate-devel] in-stream closes stream at the end: bad idea?
by daniel radetsky 22 Oct '08

22 Oct '08

Iterators: Was working with iterate, and noticed this issue. I did a quick-n-dirty fix to get rid of it (copy and paste to a new in-ostream driver). But I thought: Is there actually a good reason to close the stream at the end of the loop? Or, is there a correct way to make in-stream not close the stream that I should have been using? If not, and if there is still development going on for iterate, I can fix it up more nicely and submit a patch. My thoughts: - in-stream should, by default, not close the stream. Unlike in-file, we should expect that the stream was created by some process that will handle closing the stream at the end, such as with-open-file. - If the user wants to close the stream at the end, he should do something like (finally (close stream)). More complicated abstractions here aren't really helpful. I had also been thinking that in-stream/in-file could be modified to make it easier to pass them user-defined reading functions, but that's another post. Daniel

[iterate-devel] Support of iteration over CLSQL queries
by Кальянов Дмитрий 11 Jun '08

11 Jun '08

I have written a driver for iterating over CLSQL queries. I suggest that it would be useful to include it in iterate or mention it in manual. It is available at http://common-lisp.net/project/iterate-clsql/

[iterate-devel] Problem with DEFCLAUSE-DRIVER

Hi I am trying again to extend ENUMERATIONs with ITERATE. Here is my try ;;;; -*- Mode: Lisp -*- ;;;; iterate-enumeration.lisp -- ;;;; ITERATE extension for ENUMERATIONs.
