John,

If your name is ever submitted for sainthood, I'll sign the documents.

Many thanks from a grateful teacher!  (Now I need to learn how to do this
stuff myself...)

Okay, this might now be done. You should be able to install it using 

raco pkg install simply-scheme

OR you can use the package manager from within DrRacket.

MAJOR disclaimer: I am not a user of Simply Scheme, and this package does not 
appear to include any tests.

However, it appears that 

(+ “40” 2)

does evaluate to 42, and 

(random 34)

evaluates to different numbers on subsequent runs. That’s about all I know to 
test ….

Let me know if you have any questions or problems with it.

2017-10-22 Thread 'John Clements' via Racket Users 
Okay, I spent half an hour on this, and I think I’m done… um, almost.

Actually, it appears that my quick job of updating the drracket tool has 
resulted in a configuration that can reliably make DrRacket seg fault (!). 
Since this package does not involve FFI in any way, this is a bug in DrRacket, 
so now I’m duty-bound to see what the heck is going on.

While I appreciate the level of detail that Stephen provided, I am
absolutely slammed and don't know github usage, so what looks smallish to
you (and probably would be for me if I were better educated on the system)
is looking mighty large to me.  In terms of the fix, what needs to change
is that there is code in simply.scm that needs to be commented out;
everything else remains as it originally was.  And the code is actually
documented within simply.scm: it says to remove the RANDOM code if the
underlying interpreter supports it (which is the case here) and that's it.

The version of Scheme this was designed for was at UC-Berkeley.  It
wouldn't surprise me if there was some common ground with MIT Scheme, but I
don't know for sure.

I do plan to learn github at some point, but I'm kind of stuck at the
moment.  If it only took an evening from where I am right now, I'd do this,
but my lack of familiarity with the overall system has me very
uncomfortable.

They can be updated, but I would recommend that, instead of updating
them, you move them to pkgs, as Stephen suggests.

(Of course, if you know people are using them and they cannot easily
change your code, please do update the planet version! But in any
other situation, I'd recommend abandoning them.)

Re: [racket-users] Can anyone help me with a change?

2017-10-22 Thread Stephen De Gabrielle 
I don’t think packages on PLaneT can be updated but I may be wrong.

I have moved things from PLaneT to the Racket Package system, and it isn’t
very hard, certainly wasn’t time consuming (an evening).

1. Make a new github repo
2. add the old code,
3. Run it to see what breaks
4. Fix it - I don’t mean to sound flippant - the Racket docs and release
notes are very helpful
5. Repeat 3-4 till it works

Another option, given the book was released in 1999 for (MIT? R4RS?) Scheme
and noting the select language dialog in DrRacket allows you to select the
Scheme language; it may be easier to adapt the scheme library that came
with the book to the more recent version of scheme available in DrRacket.

There are also professional educators (I’m not) on this list who can
probably give better advice, but they probably not checking the Racket
mailing list on Sunday night!

Kind regards,

S.

Hi,

I think it's the case that making the change to `random` is simple (or
removing it if that's the appropriate thing), though I *believe* that
Danny would be the only one who could re-upload it to planet.

If you're willing to get it from a different source, e.g.
pkgs.racket-lang.org, then it should be easy enough for anyone to
upload the modified version there.

Cheers,

Andrew
