Re: mcl.googlecode.com opens for business

Dear All,

thanks for setting this up. I am a bit confused, however. Why did you  
go with Mercurial? See previous argument about de-cohesification.

RMCL, I would think, will not be a launch point various new  
development. The main role of the repository will be to absorb various  
fixes over time to keep RMCL alive for as long as possible, e.g.., to  
the point when Apple no longer supports Rosetta. In that time, the few  
developers should take any means possible to keep a unified version of  
RMCL and not to branch it out. SVN is actually really great for that.

At any rate, perhaps the community should have a bit of a discussion  
and a show of hands in terms of who is using what kind of revision  
system. We are pretty committed to SVN and right now I have neither  
the time nor energy to "play" with a new version control system. I am  
not saying Mercurial is a bad things but to be honest I actually don't  
know anybody using Mercurial.

good news: We got AgentCubes (carbon) to work with RMCL - thank you  
Clozure - with all the GUI, OpenGL, ... stuff. Some of the GPU  
intensive stuff even manages to run faster on the Intel-Macs than the  
PPC ones (not too surprising). CPU bound computing is a different story.

So far only one patch to RMCL, which I will just include in this email:


;; l1-files.lisp
(in-package :ccl)
(defun directory-pathname-p (path)
  (let ((name (pathname-name path))(type (pathname-type path)))
    (and (or (null name) (eq name :unspecific) (%izerop (length name)))
              (or (null type) (eq type :unspecific)))))


;; pathname-name can return :unspecific which, without "(eq  
name :unspecific)" creates an error when trying to compute the length  
of a symbol.


all the best,  Alex
