sbcl

At the end of section 6.5 in the current SBCL manual, we have the following quote: If your system's performance is suffering because of some construct which could in principle be compiled efficiently, but which the SBCL compiler can't in practice compile efficiently, consider writing a patch to the compiler and submitting it for inclusion in the main sources. Such code is often reasonably straightforward to write; search the sources for the string “deftransform” to find many examples (some straightforward, some less so). I've been playing around and found the likes of sb-c::defknown and sb-c:

I need something like this , a collection of elements which contains no duplicates of any element. Does Common Lisp, specifically SBCL, have any thing like this? For a quick solution, just use hash tables, as has been mentioned before. However, if you prefer a more principled approach, you can take a look at FSet , which is “a functional set-theoretic collections library”. Among others, it contains classes and operations for sets and bags. (EDIT:) The cleanest way would probably be to define your set-oriented operations as generic functions. A set of generic functions is basically equivalent

When writing Common Lisp code, I use SLIME. In particular, I compile the buffer containing definitions of functions by using C-C C-k, and then switch to the REPL to run those functions. Putting executable code to run those functions in the buffer does not appear to work so well. If the code has bugs it can make a mess. It would be handy to have a way to include code that doesn't get compiled in the buffer, but do get run from the command line, e.g. when doing sbcl --script foo.lisp If that were the case, I would not have to keep adding and removing code every time I wanted to run code from the

【实践】MS WINDOWS系统中把 SBCL 集成到 Lispbox 中 最近在分析 Lispbox 中各个组成部分的启动顺序和调用方法，略有所得，遂尝试把 SBCL 集成到 Lispbox，具体方法如下： 1、安装好 Lispbox ， 直接下载解压就可以了（我的安装目录是 F:\lispbox-0.9）； 1、安装好WINDOWS版本的SBCL（我的安装目录是 D:\Program Files\Steel Bank Common Lisp\1.1.0）； 3、在 lispbox-0.9 目录下新建一个目录 Steel-Bank-Common-Lisp，把 D:\Program Files\Steel Bank Common Lisp\1.1.0\ 下的所有文件和文件夹全部拷贝到 F:\lispbox-0.9\Steel-Bank-Common-Lisp\ 目录下； 4、修改 F:\lispbox-0.9\emacs-24.2\site-lisp\ 下的 lispbox.el 文件，修改为如下： ;(setenv "SBCL_HOME" (lispbox-file "sbcl-1.0.42/lib/sbcl")) (setenv "SBCL_HOME" (lispbox-file "Steel-Bank-Common-Lisp")) 5、把 F:\lispbox-0.9\ccl

I'm trying to figure out how to use the output stream of one program I start with RUN-PROGRAM so it can be used as the input of another program started with RUN-PROGRAM (i.e., the moral and perhaps literal equivalent of piping). I've tried using a number of combinations of the :INPUT , :OUTPUT and :WAIT keyword arguments, but nothing I've hit upon has been productive so far. Any tips would be helpful; for example, how would I go about doing something like ls | grep lisp from the shell? One of my attempts is (defun piping-test () (let ((grep-process (run-program "/usr/bin/grep" '("lisp") :input

I want to use buildapp to make the curl-lisp executable given as an example : buildapp --output lisp-curl --asdf-path ~/src/clbuild/systems/ \ --load-system drakma \ --eval '(defun main (args) (write-string (drakma:http-request (second args))))' \ --entry main This will most definitly not work, as I got no path "~/src/clbuild/systems/", as I use quicklisp my systems should be at "~/quicklisp/dists/quicklisp/software", but when I execute: buildapp --output lisp-curl \ --asdf-path ~/quicklisp/dists/quicklisp/software \ --load-system drakma \ --eval '(defun main (args) (write-string (drakma:http
