Since version 5.1 of DrRacket? the for/vector and for*/vector function is standard included in the #lang racket library. So when loading the simple-matrix module some errors are generated: "module: identifier already imported from a different source"

Maybe removing the for/vector, for*/vector from the module isn't that a bad idea then?

Furthermore the base one is a bit further extended: #lang racket: (for/vector (for-clause ...) body ...+) (for/vector #:length length-expr (for-clause ...) body ...+)

Simple-matrix: (for/vector length-expr (for-clause ...) body)

Offtopic: I would like to thank you for the module, saved me some time writing it myself, cheers!

Kind regards, Tim Coppieters. VUB

I would love it if this module supported vectors as JSON arrays. Then it would nicely interoperate with Jay McCarthy's mongodb module, and decode the BSON it produces.

The workaround I use has this small change to lines 17-18:

  [(or (list? json)
       (vector? json))

It seems that (prime? 1 2 random) will cause an infinite loop. See fixed version below (perhaps not the best solution). The only change is at the start of the function: (cond ((< x 2) #f) ((or (= x 2) (= x 3)) #t)

(define (prime? x k (rng random))

(cond ((< x 2)

#f)

((or (= x 2) (= x 3))

#t)

((let-values (((s d) (get-s-d (sub1 x))))

(let loop ((i 0))

(if (>= i k)

(let ((test (mod-exp (add1 (rng (- x 3))) d x)))

Based on the doc, the csv.ss currently exposes a csv-reader-maker functions that creates a closure over the input port for reading the csv data.

While this is convenient for just reading csv files, it doesn't work well for composing different readers as it doesn't follow the scheme pattern of

(read <input-port>)

.

It would be nice to have a csv-reader-maker that'll make a procedures that takes an input-port so the reader can be composed.

It would be nice if pict-* combined the subpicts in the order they were given, instead of the non-ghost pict always being combined first. That would be useful for #:combining via *-append instead of *-superimpose, and possibly other uses I haven't yet thought of. An small example program is below:

#lang slideshow

(require slideshow/code

(planet cce/scheme:6:0/slideshow))

(staged

[a b c] (slide

(pict-cond

#:combine vl-append [(= stage a)

(item (code a))]

[(= stage b)

(item (code b))]

[(= stage c)

(item (code c))])))

(For such uses, allowing a #:ghost keyword that allows overriding of the ghosting behavior may also be useful. That way non-active parts can be greyed or cellophaned out instead.)

I've been trying to get an sxml view of an xml document including comments and tried with

(require (planet lizorkin/sxml:2:1/sxml)) (sxml:document "my_doc.xml")

(in mzscheme)

I noticed however that sxml drops the comments and also shifts the order of attributes around, if I do it this way.

I'd like to use sxml as a format for editing xml files, since it's a little less markup-heavy than xml, but I'd need to keep the comments and order of attributes (I put the most important attribute to the front, to make it stand out). The plain xml format needs to be the master format, since people who never heard of s-expressions are going to have to edit those files.

I started diving into the source, but failed to see an obvious way to change that behaviour yet. SSAX-code.ss is impossible to read, so I had to download SSAX.scm from sourceforge. It looks like comments could be handled by a function similar to ssax:read-cdata-body.

I appreciate if you could help me out with this, maybe add one or two optional parameters to sxml:document to convert comments into sxml comments and maintain the order of attributes.

First, thank you for all the OS PLT-Scheme -- errr I mean, Racket code. I love this stuff.

There seams to be a problem with some special cases for abbreviated xpath syntax -- looks like absolute paths have problems with xpaths that start with one of : "div", "mod", "and", "or". (could be that I just don't understand the specs)

Here are the three most reliable Reg Fixers that I feel lead in the market currently. a) Registry mechanic: The Registry mechanic is designed to scan your laptop or computer for problems in the reg that slow down your laptop or computer and even crash it then helps you repair these mistakes with the many tools that it comes with. This software program can fix quite a few issues in the laptop or computer including missing help files, removed fonts, broken shortcuts and references to uninstalled software programs. The Registry mechanic additionally easily creates backups of the reg and has a Tuneup service option and a reg defragger that can enhance operating system boot services. There are of course a lot of other tools and elements that make this software program one of the most preferred by computer users. b) CyberDefender?: If you want a Reg Fixer that doubles up as an antivirus software program and anti-malware, cyberdefender certainly is your kind of software program. I think that this software program deserves the top three position because it is stealthy and catches more malware and viruses than most other antivirus software programs. It uses Dual-core anti-malware technology to give sophisticated detection and prevention and has got the option of Link Patrol that will keep you safe from adware and spyware downloads along with phishing scams. CyberDefender? comes with tons of options to customize it to your preferences and other enhancements on version 3.0 that were recommended by reviewers and users from the earlier versions 1 and 2.

Hi Dave, I sent an earlier patch to struct.plt 2.3 to make it work with mzscheme 3.99, but didn't hear back from you yet. In any case, I took a look at it again, and the patch wasn't so good because it made it work only with mzscheme 3.99, which broke backwards compatibility. Since you probably want to make it work regardless of version, I've updated the patch so that it uses version-case to do the appropriate version-specific stuff. Summary of changes: * I created a separate module 'private/struct-info-compat.ss' which provides a function to get the predicate from the struct type syntax object. I updated datatype.ss to use this library. * As in the previous patch, I also modernized the test cases to use SchemeUnit? 2. The tests involving hierarchy are failing, but I don't think it's a problem with my patch, but rather with a missing 'definitions' collection that I don't know much about. I hope this helps!

Hi, `stream-split-at' in stream.plt 1 1 only returns one value, and attempting to use that value results in errors. I looked at the source and I think there's a simple oversight:

  (define (stream-split-at i stream)
    (stream-delay
;    ^^^^^^^^^^^^ 
     (cond
       [(zero? i)
        (values stream-null stream)]
       [(stream-null? stream)
        (values stream-null stream-null)]

        (let-values ([(prefix suffix) (stream-split-at (sub1 i)
(stream-cdr stream))])
          (values (stream-cons (stream-car stream) prefix) suffix))])))

I don't think stream-delay is correct here! At least, when I changed the code to:

  (define (stream-split-at i stream)
     (cond
       [(zero? i)
        (values stream-null stream)]
       [(stream-null? stream)
        (values stream-null stream-null)]
       [else
        (let-values ([(prefix suffix) (stream-split-at (sub1 i)
(stream-cdr stream))])
          (values (stream-cons (stream-car stream) prefix) suffix))]))

the routine behaved as I expected. Is this a bug or am I missing something basic? Do you have a good example of using stream-split-at? With the original code, I tried:

(stream-split-at 3 (list->stream (list 1 2 3 4 5 6)))

#<struct:stream>

(stream-car (stream-split-at 3 (list->stream (list 1 2 3 4 5 6))))

. context (lexical binding) expected 2 values, received 1 value: #<struct:stream>

which left me cold, but with the new code, I was able to do:

(stream-split-at 3 (list->stream (list 1 2 3 4 5)))

#<struct:stream> #<struct:stream>

(let-values ([(front back) (stream-split-at 3 (list->stream (list 1 2

3 4 5)))]) (values (stream->list front) (stream->list back))) (1 2 3) (4 5) which is about what I expected to need to do. If this is a bug, then I think stream-partition and stream-span suffer the same bug. If it's not a bug, then apparently the bug is in my brain for not figuring out the right API. Thanks, Steve Huwig P.S. stream-split-at reverses the order of split-at arguments from SRFI-1, not sure if that's deliberate.

It appears that there's some kind of stateful sequence where you add pieces of data and then call plot, but I'm not sure whether it gets reset when you plot, etc. The docs on gnuplot-plot are also less helpful than they could be; it appears from the way the docs are structured that calling 'gnuplot-plot' is supposed to open a window; it doesn't, on my machine, but I can't tell whether this is a doc bug or a gnuplot.plt bug (or whether I just need to update DrScheme?, which I'm trying now).

(parse (peg (start s) (grammar (s ((_) $)))) "a")

If the first line in an ocaml file is blank, it appears that drocaml does not do any indenting further down.

How to repeat:

- Change to drocaml language - Open new frame - type <return> let x = <return>x

The x does not jump to the right, nor does <tab> work correctly. Removing the blank line at the beginning of the frame fixes everything up.

Another bogosity in dracula docs:

The module MDistributeLists provides an implementation of IDistributeLists for any implementation of IDistributive:

  (module MDistributive
    (import IAssociative (addop a))
    (import ICommutative (addop a))
    (import IDistributive (addop a) (mulop m))
    (defun add (xs)
      (if (endp (cdr xs))
          (car xs)
          (a (car xs) (add (cdr xs)))))
    (defun mul (x ys)
      (if (endp xs)
          nil
          (cons (m x (car ys)) (mul x (cdr ys)))))
    (export IDistributeLists (addall add) (mulall mul)))

Reported by pnkfelix, 16 years ago.

Here is (slightly modified) code from the 8.2 reference manual:

(interface IAssociative
  (sig mulop (x y))
  (con mulop-associative
       (equal (mulop a (mulop b c))
              (mulop (mulop a b) c))))

(interface ICommutative
  (include IAssociative)
  (con mulop-commutative
       (equal (mulop a b) (mulop b a))))

(interface IDistributive
  (include IAssociative)
  (include ICommutative)
  (sig addop (x y))
  (con addop/mulop-distributive
       (equal (mulop a (addop b c))
              (addop (mulop a b) (mulop a c)))))

(module MDistributiveA
  (defun add (a b) (+ a b))
  (defun mulop (a b) (* a b))
  (export IAssociative (addop add))
  (export ICommutative (addop add))
  (export IDistributive (addop add)))

(module MDistributiveB
  (defun add (a b) (+ a b))
  (defun mul (a b) (* a b))
  (export IAssociative (addop add))
  (export ICommutative (addop add))
  (export IDistributive (addop add) (mulop mul)))

Hitting RUN for this example raises the following error:

. mulop: undefined in: mulop

(it also highlights the mulop in the IAssociative interface, which is not terribly useful and may be a usability bug; read on for why I think this.)

If I comment out the definition of MDistributiveB, so that MDistributiveA is the only module providing relevant exports, then the code runs fine.

I assume the problem here is something along the lines of "the docs should be changed so that the MDistributive module exports mul/mulop instead of add/addop into the IAssociative interface.

More generally, all of the examples in the dracula docs need to be tested directly.

(html->sxml "<div><input name=a><input name=b></div>") produces ((div (input (@ (name "a")) (input (@ (name "b")))) (input (@ (name "b")))))

Note that the input element named b is produced twice. My guess as to what is happening is that since the inputs are unclosed, the parser doesn't close them until it hits the closing </div>. At this point, it figures out that everything unclosed beforehand should be closed and notes two input elements that should be closed and closes them. However, it had already parsed the first input as containing the second input in its body, and since it doesn't reparse this it ends up closing the first input after it encloses the second input as well as closing the second input. I doubt this is intended behaviour.

This came up on yahoo.com (god, why can't they write html). Browsers rendered the site as intended (as if it was <div><input name="a"/><input name="b"/></div>), but the html->sxml parser did not.

To the developer of beanscheme.plt,

Your frequent updates of beanscheme.plt are understandable, as it allows you to test out each intermediate version of your software. However, I am sure it is a hassle to create, upload, and redownload your software; furthermore, it creates unnecessary posts on the planet-announce mailing list.

I suggest that you read about "development links" which let you compile and test PLaneT packages on your own computer, uploading only when you need to publish code for other users.

You can find documentation about development links here (this tinyurl.com address links to a specific page on docs.plt-scheme.org):

wx_read_png function 729 line.

My computer:

OpenSuse? 11.3 libpng 1.4.3

I have solve problem by changing that line from:

png_set_gray_1_2_4_to_8(png_ptr);

to:

png_set_expand_gray_1_2_4_to_8(png_ptr);

Works for me, but I am not sure if it works for everyone.

Hi Dave,

I'm very fond of your define-datatype macro as it enables me to create abstract datatypes. Unfortunately I have to implement #:property prop:equal+hash in some cases where I use define-datatype. Would it be possible to enhance the macro for that?

BTW I'm not sure if it's ok to create a ticket for this; it seemed better than writing a private mail.

Many thanks in any case Sigrid
