mit-scheme

In order to debug MIT-Scheme scripts with Vim, I want to be able to run the script file currently being edited as conveniently as possible. Here is what I'm doing: sicp.scm (set! load-noisily? #t) (define (abs x) (cond ((> x 0) x) ((= x 0) 0) ((< x 0) (- x)) ) ) (abs 42) (abs -24) (exit) After executing :!mit-scheme --eval "(load \"sicp\")" when editing sicp.scm in Vim, I get: Image saved on Saturday May 17, 2014 at 2:39:25 AM Release 9.2 || Microcode 15.3 || Runtime 15.7 || SF 4.41 || LIAR/x86-64 4.118 Edwin 3.116 ;Loading "sicp.scm"... Kill Scheme (y or n)? There are two main issues: The

I am just hacking around with Scheme (mit-scheme) and I have just figured out how you change the environment, so that '+' becomes a symbol for the equivalent procedure of the '-' operator. Example (environment-define user-initial-environment '+ -) (eval (+ 3 2) user-initial-environment) => 1 I was just wondering if there were a simple way to deal with environments as variables so when I input an environment into eval, like so (eval <exp> user-initial-environment) I don't have to use 'user-initial-environment'. So I can 'play' with different environments for a function. (eval <exp> env) Where

I want to evaluate a script from makefile and exit, like this mit-scheme --load "fact.scm" However, after it evaluates the file, it does not exit, and the repl appears; if I try the (exit) primitive, it asks for confirmation y/n. Is it possible to solve this ? For Unix mit-scheme reads the input files via redirection: mit-scheme < /usr/cph/foo.in > /usr/cph/foo.out 2>&1 & This is taken from the documentation http://www.gnu.org/software/mit-scheme/documentation/mit-scheme-user/Command_002dLine-Options.html#Command_002dLine-Options Charlie Forthmount Just let our command close stdin of the mit

I'm reading SICP and I'm using mit-scheme installed on my os x 10.8 laptop via homebrew . Everything works as advertised, however I'm spoiled by the ease with which I get tab completion and command line history in REPL's for runtimes like Python and Node.js. I'm not looking for anything heavy duty, but these features are pretty easy to come by in modern REPL's (it's just a simple startup file in Python and can be implemented in a few lines in Node.js ). Is there an easy way to get tab completion and command history in the mit-scheme REPL without a heavy-duty application or having to switch to

I am stuck up in a Scheme program for about 5 hours. The program that I am working on should take two lists as input and then compute the number of times the pattern within the first list appears on the second list. For example : > (patt '(b c) '(a b c d e b c)) ==> answer = 2 (patt '(a b c) '(a b c a b c d e a b c c c)) ==> answer = 3 (patt '((a b) c) '(a b (a b) c d e b c)) ==> answer = 1 Below is the code that I have till now. (define (patt lis1 lis2) (cond ((null? lis1) 0) ((null? lis2) 0) [(and (> (length lis1) 1) (eq? (car lis1) (car lis2))) (patt (cdr lis1) (cdr lis2))] ((eq? (car lis1)

I have installed SublimeREPL, and now I am trying to customize the interpreters a bit. How can I add MIT Scheme to the Tools->SublimeREPL menu? I am new to Sublime Text 2. You can read documentation about configuring additional REPLs here: http://sublimerepl.readthedocs.org/en/latest/#basics-of-language-integration-configuration-and-launch-commands And take a look at existing Scheme configuration here: https://github.com/wuub/SublimeREPL/tree/master/config/Scheme Most Scheme/Lisp dialects are quite easy to configure, you should have no problems whatsoever. Please allow me to share my

I want to type something like 'scheme file.scm' and have it interpret the file, and then take me back to my shell, rather than loading it in the REPL. edit: I tried scheme < test.scm and it still uses the REPL, the only difference is that scheme exits when the stream ends. scheme <file.scm should work (as long as you don't specify --interactive and stdin is not a terminal, scheme works non-interactively). To run a scheme program using MIT Scheme: scheme --quiet < program.scm The --quiet option ensures that the output from your program is the only thing that is displayed (i.e. you won't see the
