Emacs Lisp works only within Emacs, as far as I understand, so there is no way to do that. There is no need either -- people who use Emacs use it for everything. If you want to make a standalone program, you should try Common Lisp or Scheme instead of Emacs Lisp.

That's why there's a different "Casting Spels in Lisp -- emacs lisp edition". In general we will use emacs lisp only to customize emacs. For any other program we will stay with Common Lisp. Most CL implementations include a REPL, and the standard CL:LOAD and CL:COMPILE-FILE functions. Some other way of interacting with the implementation may be provided either by the implementation itself (eg. some implementation provide a GUI where you may type expressions and display results somewhat like with a REPL), or as add-on (eg. you may write a web server that allows you to evalate lisp expressions (at least in debugging mode), an example being Uncommon Web). You could also provide an access to you implementation by writing a telnet server (for example, you could try Allegro CL with telnet://prompt.franz.com/ So the answer to your question > is there some other way ? is YES. > I use emacs lisp. We doubt it. That is, unless you're reading "Casting Spels in Lisp -- emacs lisp edition". But if you really "used" emacs lisp, that is, programmed in emacs lisp, you would rather ask your questions on news:gnu.emacs.help ;-) However, emacs provides the same kinds of interaction as the Common Lisp implementations. Emacs lisp Common Lisp REPL: M-x ielm RET ; this is the default ; you launch the ; implementation. load source: (load "f.el") (load "f.lisp") M-x load-file RET f.el RET compile source: (byte-compile-file "f.el") (compile-file "f.lisp") load compiled: (load "f.elc") (load "f.fas") M-x load-file RET f.elc RET ; extension may ; change depending ; on the implementation. When you use emacs as a front end to lisp, you can in both case send expressions from a buffer to emacs lisp or the "inferior" lisp, that is to the Common Lisp implementation: evaluate an (exp) C-x C-e (exp) C-x C-e expression: ; in an emacs-lisp-mode ; in a lisp-mode ; buffer ; buffer M-: (exp) RET Other commands are also available, depending on the interaction mode you may use (inferior-lisp, slime, etc). In emacs you can get help about the commands available in the current mode with C-h m > Loading a file will do for now but I would like to know how to compile > it ? See above. Notice also that for lisp "systems", a system definition facility such as defsystem (old) or asdf (current) or xcvb (future) is also used, and then compiling or loading the system is done using functions specific to the system definition facility. > I guess I have to download MinGW or something ? No. What use would a C compiler be of? > Can I compile this source code to run it from command prompt ? Yes. See above. I consider that compilation is a late optimization option. When you're learning a language or developping a new application, you don't need to compile, because you don't need your programs to run fast. If your lisp implementation compiles automatically, good. But there's no point in asking explicitely such an optimization. Concentrate on writing clear and correct code, test and debug it well. When it's done and it's time to consider deployment, if it is expected that the users will have a lot of data to process, then you may consider proclaiming the optimization declarations and to ask your lisp implementation to compile the programme. But only if you need it to run fast. COMPILE-FILE is an improper function name. It should have been named OPTIMIZE-FILE-FOR-RUNTIME-SPEED. -- __Pascal Bourguignon__
From: Haris Bogdanovic on 1 Mar 2010 16:50 OK. So I should install slime if I want to program in common lisp. I saw in slime help document few commands for emacs to install inferior lisp. Can someone tell me what exactly to write to install common lisp with slime ? I'm asking all this question about emacs, should I ask them in a different newsgroup ? How can I tell emacs to load some file at startup automatically ? Thanks

Not necessarily. emacs -q RET launch emacs without reading ~/.emacs C-x b *scratch* RET go to the *scrath* buffer (require 'cl) C-x C-e to get setf (setf inferior-lisp-program "clisp") C-x C-e tell inferior-lisp what lisp you use M-x inferior-lisp RET launch inferior lisp C-x 2 split a window C-x C-f example.lisp RET open a lisp file. (defun f (x) type in a definition (if (< x 1) 1 (* x (f (1- x))))) C-x C-e and send it to the inferior lisp (f 10) C-x C-e type in an expression and send it to the inferior lisp So you can go a long way without slime. However, slime provides a lot of nice features you could learn to be unable to live without. Slime gives a much higher integration between the emacs user interface and the inferior lisp than the basic inferior-lisp mode of emacs. > I saw in slime help document few commands for emacs to install > inferior lisp. Can someone tell me what exactly to write to install > common lisp with slime ? There are a lot of manuals and tutorials and even videos explaining how to install or use slime. Use google and http://cliki.net/ > I'm asking all this question about emacs, should I ask them in a different > newsgroup ? Actually, while slime is an emacs package, questions about slime are entirely relevant here. After all it's use is (almost exclusively) for lisp development and it has been written by lisp programmers, so it is here you will find the best support for slime. Other questions about emacs concerning its use for lisp programming will also find an answer here. Even questions about emacs lisp, as far as they are general lisp programming questions would find good answers here. However, any programming languages may be split into three parts: - a core implementing the basic semantics of the language, - a "standard" library considered part of the language, - an ecology of add-on libraries, tools and cultural knowledge surrounding it. In the case of emacs, there's a core emacs lisp, there's a "standard" library which makes it a recognizable lisp. Questions about these parts could be answered here. And then there are a lot of libraries, tools, applications and other features added over emacs lisp to implement the emacs editor, and all the optional modes, and all the emacs applications such as network clients (email, erc, news, web, whatever), games, spreadsheets, IDE for various kind of development and languages, various applications user inteface front-ends, etc. Unfortunately, most questions about these big parts cannot be answered here because we may not have the required knowledge. For example, if you asked a sharp question about writing a mode, or about using a specific mode such as org-mode, I wouldn't know anything about it. These questions will be better answered on news:gnu.emacs.help or one of its brother groups. > How can I tell emacs to load some file at startup automatically ? All lisp implementations search for some specific file to load at startup. clisp loads ~/.clisprc sbcl loads ~/.sbclrc cmucl loads ~/.cmucl-init.lisp emacs loads ~/.emacs (or ~/.emacs.el) You can put any lisp expression in these files (emacs lisp expression in ~/.emacs). You could have learn earlier about this file by reading the manual of emacs, ie. typing these shell commands: man emacs info emacs Also, you can read info files from emacs with M-x info RET or C-h i You may start putting: (require 'cl) (setf inferior-lisp-program "clisp") in your ~/.emacs so that you don't have to type and evaluate them again in the *scratch* buffer next time you start emacs. -- __Pascal Bourguignon__

I put commands from cliki manual to my init.el file. When I type C-u M-x slime it looks in emacs bin directory and whatever file I choose I get access denied. What file should I put in init.el to work with clisp ? This is what I copied into init.el: (add-to-list 'load-path "c:/slime") (require 'slime) (add-hook 'lisp-mode-hook (lambda () (slime-mode t))) (add-hook 'inferior-lisp-mode-hook (lambda () (inferior-slime-mode t))) ;; Optionally, specify the lisp program you are using. Default is "lisp" (setq inferior-lisp-program "swank-clisp.lisp") How do I make it to look in the c:/slime directory ? How do I set default folder for emacs (when I want to open file it goes to bin folder) ? |
