Re: New to Common LISP,Need help in String manipulation function

I think you should use some XML-Library for this (S-XML, etc.) - see cliki.net for a list of XML-Libraries for lisp.

Has anyone used 0install?

I just read about 0install, http://0install.net/ . Seems like it tries to become a way of installing software locally as a user, which is something very desirable in some situations. Has anybody tried this yet? Especially, such a thing could be a nice addition to clbuild / quicklisp, in the sense th...

Re: State of user extensible sequences

Thank you. Yes, that works. I wonder how efficient this is, I think I would not have implemented this extension with the object system, but rather with callbacks, for reasons of efficiency, but who cares. I wonder why other implementations do not adapt this. Having some mechanism of optimizing what ...

State of user extensible sequences

As it would come handy in what I am currently programming, I was wondering whether "User-extensible sequences in common Lisp" described in http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.65.1604&rep=rep1&type=pdf or something similar has already made its way into some common lisp implementa...

Re: Copy-on-Write Mapping of Memory - is it possible?

This was not an SBCL question, I am not sure how come that you talk about it. And as I pointed out, I just wondered whether this was possible with some system. Trivially, a Copying GC cannot make an advantage of copy-on-write pages directly (however, indirectly, it could optimize some parts, like th...

Copy-on-Write Mapping of Memory - is it possible?

Whjat I was wondering since a long time now is whether it is possible to map a part of the current heap memory onto another one in a Copy-On-Write-Manner, like it is done when fork(2)-ing under Linux, just that the same process can request it explicitly. In theory, using some magic with libsigsegv s...

Is there a Scheme implementation in CL

Hello. Is there any Scheme implementation in CL? I am looking for one since quite a lot of time now, since I have some code that must be written in r5rs-scheme, but would like to use it under CL too. Writing an r5rs-compatible scheme to integrate it in common lisp should not be that hard, since as f...

Re: Low-Level File Access

reading into a sequence needs a lot of memory. using mmap is faster and normally simpler, otherwise one would have to implement random access. I wonder why mmapped files accessible via normal sequence ops are not already a common extension to cl. I mean its something obvious and should be easy to im...

Re: Problems with CLISP and Fastcgi

Ok. I changed the LogLevel to Debug. Somehow, fastcgi:write-stdout doesnt support the application of more than one string as an argument. Additionally, what confused me is that the only possibility to be really sure that the fastcgi-script is re-read is to completely restart apache. The following co...

Problems with CLISP and Fastcgi

I managed to compile CLISP with the FastCGI-Module on Debian, using the Debian-Sources under squeeze and adding the configure-flag --with-module=fastcgi. Now, *features* contains :FASTCGI. Running the example given on http://clisp.cons.org/impnotes/fastcgi.html in cgi-mode anything works fine. Runni...
