Re: [racket-dev] gui responsiveness
As a side note, I remember having stumbled on the same issue some while back, and the way I dealt with it was to refresh based on a random outcome. Not clean, but it works pretty well as long as the refresh calls are still close enough.

It's good to know that the ordering is intentional, and to have some nice ways to work around it if needed. The reason I thought that refreshes were lower priority was because of the scrollbar behavior in the program below. On Unix/X, dragging the scrollbar back and forth does lots of paints, but I only actually see a few of them. Does that sound like a bug to you? #lang racket/gui (define num-on-paint 0) (define frame (new frame% (label Refresh) (width 500) (height 500))) (define (draw-screen canvas dc) (set! num-on-paint (add1 num-on-paint)) (sleep 0.1) ; simulate a longer painting effort (send dc draw-text (~a num-on-paint paints) 400 70)) (define canvas (new canvas% (parent frame) (paint-callback draw-screen) (style '(no-autoclear hscroll (send frame show #t) (send canvas init-auto-scrollbars 700 #f 0.0 0.0) On 04/16/2014 01:56 PM, Matthew Flatt wrote: You're right that it's about event ordering and not refresh coalescing. Since mouse events are handled after refreshes, you won't get the next refresh request until an earlier one is handled, after which the next mouse event can trigger another refresh request. I think the difference between Unix/X and Windows may be that Windows sends fewer mouse events. There are trade-offs here, but my experience is that ordering input events before refresh does not work well in general. To trigger refreshes at a lower priority in this case, you could use Neil's suggestion or change (send this refresh) to (set! needed? #t) (queue-callback (lambda () (when needed? (set! needed? #f) (send this refresh))) #f) ; = low priority where `needed?` is a field that's initially #f.

Can anyone else on Linux reproduce this behavior? The patch below dramatically improves the responsiveness by forcing the eventspace to process medium-level events (mouse movement) before refresh events. Without the patch, each mouse drag causes a paint. With it, multiple mouse drags are processed before a paint. I'm unsure about this fix. Windows doesn't show the problem (I don't have a mac to test), so I think it's just a GTK issue. My guess is that the gui layer is relying on the native libraries to coalesce multiple refresh requests (but this is not working with GTK). Can anyone confirm this?

To make this info easier to find, I'm wondering if the racket-lang.org maintainers would be interested in publishing a canonical index of Racket courses (both online and in-person) linked off the Community or Learning sections on the homepage, and inviting the community to add to it. (Similarly, linking to a canonical index of Racket meetup groups (à la http://clojure.meetup.com/ and https://wiki.python.org/moin/LocalUserGroups) would be great too.

[racket-dev] class implementation and make-primitive-class
For a course project I've been working on adding generators to contracts for use with contract-random-generate, and I've been trying to construct classes and objects from simple object/c contracts. When trying to find a way to functionally create a class at runtime, I came across the `make-primitive-class` function in class-internal.rkt. This function is exported, and available at a plain racket repl, but has no documentation that I have been able to find and the comments about it in class-internal.rkt seem to be incorrect. Trying to call it from the repl has problems also, for example (ignoring for a moment that the arguments aren't of the expected types) - (make-primitive-class #f #f 'foo object% null #f null null null null) ; compose-class: arity mismatch; ; the expected number of arguments does not match the given number ; expected: 28 ; given: 27 The definition is in terms of compose-class and is just missing a `null` argument for the abstract-names, but even after fixing that in my local branch there is a discrepancy with the comments regarding it's first argument `make-struct:prim`. ; The `make-struct:prim' function takes prop:object, a class, ; a preparer, a dispatcher function, an unwrap property, ; an unwrapper, and a property assoc list, and produces: ;* a struct constructor (must have prop:object) ;* a struct predicate ;* a struct type for derived classes (mustn't have prop:object) ; ; The supplied preparer takes a symbol and returns a num. ; ; The supplied dispatcher takes an object and a num and returns a method. ; ; The supplied unwrap property is used for adding the unwrapper ; as a property value on new objects. ; ; The supplied unwrapper takes an object and returns the unwrapped ; version (or the original object). ; ; When a primitive class has a superclass, the struct:prim maker ; is responsible for ensuring that the returned struct items match ; the supertype predicate. This suggests that make-struct:prim should take 7 arguments, but passing a function of 7 arguments to it from the repl produces: - (make-primitive-class (lambda (a b c d e f g) (values #f #f #f)) #f 'foo object% null #f null null null null) ; #procedure: arity mismatch; ; the expected number of arguments does not match the given number ; expected: 7 ; given: 5 Also as far as I can tell `make-primitive-class` is never used in the code base, it is defined in class-internal.rkt, but can be commented out without seeming to break anything else. Does anyone know if there is a purpose for this function, or if there is documentation somewhere on the functions I need to pass it in order to construct a class. I think I'm starting to get a better idea of how it might work from reading more of class-internal.rkt and how the class* macro expands, but any guidance would be appreciated.

Re: [racket-dev] class implementation and make-primitive-class
The `make-primitive-class` function is a leftover from pre-v5.1 days, where the problem was to turn a C++ object into a Racket object. I'm not surprised that it has rotted away, it should be removed entirely, and I doubt that it's what you would want even if it worked.

Re: [racket-dev] class implementation and make-primitive-class
For purposes of your course project, couldn't you make your own class-instance object system, atop structs or hashes, that gives you whatever dynamic programming features you want? It's very-very easy to do a basic one (with single inheritance and single dispatch), until you get into speed optimizations. Or, if Swindle has a MOP, you could use that.

Re: [racket-dev] class implementation and make-primitive-class
That wouldn't work for this project because I need to be able to generate an object that satisfies a given Racket contract and can be passed to user functions that expect such an object so I need to use Racket's class system. I have a working prototype that builds class syntax then calls eval-syntax on it, I was just trying to figure out if there was an easy way to avoid using eval.

[racket-dev] Adding flvector to match
It would be really handy for me right now to be able to match on flvectors, and I think it's useful enough for minimal Racket. I've already tried this option: 1. Export flvector as a match expander from racket/flonum but racket/match depends on racket/flonum somehow. So I looked through the match code and determined that this one would be pretty easy: 2. Change racket/match to recognize patterns with 'flvector head (The code is very clean; kudos to whoever last rewrote it. :D) I think #2 would at worst hijack someone's custom flvector match expander, but probably do the same thing or better (e.g. also handle ellipses).

If you use `git submodule update' today and forget to use it in the future, probably things will be fine for a long time, because native-pkgs doesn't change often. If native-pkgs does change and you forget `git submodule update', then (as I understand things) `git status' will tell you that there's a mismatch.

stale git submodules show up on a status. What I've found helpful is to add
a bit in my prompt that tells me if the current git repository has a non
up to date status (And the current branch). If you're running Zsh this is
a good place to start for that:
git_prompt_info() {
ref=$(git symbolic-ref HEAD 2 /dev/null)
if [[ -n $ref ]]; then
echo -n [%F{red}${ref#refs/heads/}%f
st=$(git status -s 2 /dev/null)
if [[ -n $st ]]; then
echo -n %f*%f
fi
echo -n ]
fi
}
export PS1='$(git_prompt_info)[%F{green}%m%F{white}:%F{blue}%2c%f] '
Or on Bash:
function git_prompt_info() {
ref=$(git symbolic-ref HEAD 2 /dev/null | cut -d'/' -f3)
if [[ -n $ref ]]; then
# Zsh prompt this was based on
# echo [%{$fg_bold[green]%}${ref#refs/heads/}%{$reset_color%}]

Although this is unlike the previous symptoms of stale submodules,
draw-x86_64-macosx-2 sounds like something that might be related to
native-pkgs. So on a hunch I tried this:

Although it was an unusually slow/big fetch, it succeeded.
And now the build now. (Well as I type this, my laptop fans are
blazing away, as it is still running the raco setup stage. But it
proceeded OK past the point it was failing before.)
Maybe this is obvious to everyone else, but I wanted to mention it in
case it helped anyone else building on OS X.

Nothing has been split out of the current git repository, but there is
now a native-pkgs git submodule for the native-library packages.
If you build on Mac OS X or Windows or if you run a snapshot build,
then you'll need to use
git pull
git submodule init
git submodule update
once on each repository checkout from now on, and
git pull
git submodule update
for updates after the first checkout.
If you just `git pull' without the submodule commands, then you'll have
an empty native-pkgs directory. That's fine if you're building on,
say, Linux. If you're on Mac OS X or Windows, then the

Re: [racket-dev] Using `git submodule` vs. `git pull --ff-only upstream master`
Yes. FWIW I do:
function parse_git_dirty() {
[[ $(git status 2 /dev/null | tail -n1) != *working directory
clean* ]] echo *
}
function parse_git_branch() {
git branch --no-color 2 /dev/null | sed -e '/^[^*]/d' -e s/*
\(.*\)/\1$(parse_git_dirty)/
}
Which goes into the the end of:

And now that you mention it, I _did_ see the * in my prompt. I
should have paid attention to it, but
`git status` showed nothing. I should have done `git diff`.
Sorry for the noise here. (My total experience with git submodule
updates consists of the 2 or 3 times I've had to do this with Racket
-- and at intervals of enough months that I manage to forget in
between.)
