Question

I have been using PLT Scheme, but it has some issues. Does anyone know of a better implementation for working through SICP?

Was it helpful?

Solution

Use MIT Scheme.

It's recommended by the authors of SICP, and is used at MIT for the 6.001: Structure and Interpretation of Computer Programs course.

OTHER TIPS

Use Racket (formerly PLT Scheme).

The DrRacket IDE is an excellent starting point for all things Scheme including SICP.

To look up keywords in the documentation, place the cursor on the keyword and press F1. In DrRacket you can now see the images directly in the REPL (the read-eval-print-loop).

SICP Support for DrRacket, by Neil van Dyke.

Update: The new SICP package is at http://pkgs.racket-lang.org/#[sicp] Download it with the Package Manager (in DrRacket) or use raco. Manual

Update2: Also if you want to try a new implementation of the SICP picture language, then download sicp-pict2.rkt.

MIT/GNU Scheme, just make sure you load the SICP compatibility package (yes, they provide specific libraries to enhance guarantee the SICP exercises work).

I've just started do SICP this week.

Currently, MIT Scheme is broken in in Ubuntu Linux (9.04 "jaunty"). It might be working in the future.

DrScheme is working, and is working well. You can use soegard's package listed above or Neil Van Dyke's package, which is based on soegard's package and is available from http://www.neilvandyke.org/sicp-plt/. The nice thing about this package is that when installed, you can use Language|Choose Language.... menu item to select SICP.

This was suprisingly annoying to get done on macOS. Here's how it works as of today, assuming you have Homebrew. (Might want to run brew update once in a while).

brew cask install racket
raco setup  # might be optional
raco pkg install sicp

Now you can (require sicp) or simply run

racket -l sicp --repl

Which you might want to abbreviate to scheme. In bash that'd be

alias scheme='racket -l sicp --repl'

which you can add to your ~/.bashrc

PLT Scheme works pretty well, or MIT Scheme as Keparo suggested. What issues are you having with it?

CHICKEN Scheme has an sicp library that provides support for SICP. You can install it by running chicken-install sicp and writing this at the beginning of your source code: (use sicp).

I'm now working through SICP using Chez Scheme. It's a pretty old dialect of Scheme, so presumably it isn't too far from what SICP was written around.

Note that the Chez Scheme project page links a Windows binary and source that can be built on Unix-like platforms. But if you're on a Mac, you'll probably want to do

brew chezscheme
man chez

Assuming you have homebrew, which you really should.

Why not MIT Scheme? Because the interactive front end is Edwin, an editor that uses EMACS conventions. (Currently, it's an actual EMACS mode, tho it used to be implemented in Scheme.) I used to know basic EMACS, but my skills atrophied from disuse, which tells me that relearning this editor is just not worth the trouble.

Why not DrRacket? If I had seen @frederick-squid 's brew instructions, I might have given it a try. Instead I tried to follow the official instructions for scheme and sicp, which are seriously out of date. Then I tried to make the IDE go into scheme mode, which seems to be intuitive but isn't.

Just too much trouble. And I'm not sure I want to get into a fancy language design IDE, especially one whose poor support of Scheme sparked the original question.
