IIUC, Marijn is talking about the required libraries for compiling Racket, and since cairo is used in the doc build, it is needed, which (at least in the Fedora package I have) means that you also need to have X installed. Indeed I am inquiring after the libraries required for compiling Racket. On Gentoo, cairo can be configured ``without X'' (whether X is installed or not), so if cairo is really needed for building ``without X'' it is no problem to specify that. So my question is then, is cairo really needed for compiling the textual part of Racket or is it a dependency that slipped in by accident? Marijn: if this is a problem, you might get around it by avoiding the documentation build, but maybe not -- I think that the icon build also requires it. It's not a problem. I'm trying to correct a user-reported error in the dependencies of the Gentoo Racket package. If I made a wrong inference/assumption about when cairo is needed, then I want to correct that. My initial thought though, was that it was an inadvertent dependency for the textual part.

Switching tabs when running the following example exhibits the problem. Can anything be done about it? So it seems a missing container-sequence block was causing unnecessary extra problems. With it switching tabs is a lot less painful. However, unfortunately trying to resize the window when showing the second tab is still glacial/unusable. Some clarifications: 1) I'm not claiming the problem is in the table-panel class. I'm just using it as my vehicle to put lots of widgets on the screen. As far as I can judge there is nothing in table-panel that could cause this performance problem. 2) This is a test case reduced from a real program. Therefore the way it goes about recreating widgets cannot be justified without the context of the larger program. It is still not very small, but I did not see a way to make it any smaller without destroying the essential behavior. You can find a reduced test case for just the window resizing problem below.

[racket-dev] platform dependence with tab-panel callback
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, if you create a tab-panel with a callback, then on GNU/Linux the callback is called once by the system, but on Windows 7 it isn't. This can result in different initial tab visibility. For example: #lang racket/gui (define root (new frame% (width 300) (height 300) (label Test tabs))) (define (tab-callback tab-panel event) (send tab-panel change-children (lambda (children) (list (vector-ref tab-vector (send tab-panel get-selection)) (define tab-panel (new tab-panel% (parent root) (callback (lambda (tab-panel event) (displayln called!) (tab-callback tab-panel event))) (choices '( (define tab1 (new panel% (parent tab-panel) (style '(deleted ; === (define tab2 (new panel% (parent tab-panel) (style '(deleted (define msg1 (new message% (parent tab1) (label visible?))) (define tabs `((,tab1 . t1) (,tab2 . t2))) (define tab-names (map cdr tabs)) (define tab-vector (list-vector (map car tabs))) (send tab-panel set tab-names) (send root show #t) The difference in this example is caused by all tabs being initially deleted and the callback always enabling one tab. Arguably this is not a valid configuration (I don't know), but there are other ways to tickle this difference that don't rely on that: any effectful callback would exhibit the difference. Is it possible to remove this platform-dependent difference?

The first other random example I tried was `split-string' in Emacs, which did the same thing as Racket. They may choose python's version as the goal. It doesn't look like they have looked very hard as of yet at what else is out there. Probably because they are expecting compatibility between most implementations. Welcome to Racket v5.2.0.7. (regexp-split ([^0-9]) 123+456*/) '(123 456 ) should it be considered a bug in racket that it doesn't support capturing groups in regexp-split? No. Without the capturing group the results are identical: [...] Which is expected. Good, just establishing a baseline here, but it is good that some compatibility is *expected*. How nice is that? Since we're expecting compatibility between python and racket, I guess it goes without saying that racket's and guile's regexp-split should be compatible as well. R7RS Large may standardize a regular expression library, and we can make that easier by reducing incompatibilities between schemes. We can all grow from examining our incompatibilities, discussing them and sometimes resolving them. Python does something which is IMO very weird: re.split(([^0-9]), 123+456*/) ['123', '+', '456', '*', '', '/', ''] It's even more confusing with multiple patterns: re.split(([^0-9]([0-9])), 123+456*/) ['123', '+4', '4', '56*/'] There's probably uses for that -- at least for the simple version with a single group around the whole regexp, but that's some hybrid of `regexp-split' and `regexp-match*': it returns something that interlevase them, which can be useful, but I'd rather see it with a different name. Yes, I agree that I find it a bit weird as well. You don't lose anything by supporting this though, since you can always use a non-capturing group, but I do agree that it can be considered an inappropriate extension of the meaning of regexp-split. I'll be sure to raise these issues on the guile list. We've talked semi-recently about adding an option to `regexp-match*' so it can return the lists of matches for each pattern, perhaps add another option for returning the unmatched sequences between them, and give the whole thing a new name?

Interestingly, after playing with it for a while, suddenly when I run it the plot produced has a different viewing angle and dragging it is actually working.

On a closer inspection I notice that some of the vertical parts of the stairs are slanted after zooming in (will send screenshots privately). The thing is, the error shouldn't be happening at all. As far as I can tell, it happens because at least one surface normal of a polygon that makes up the plot has a +nan.0 in it. That *could* happen if your machine's floating-point processor is pretty b0rked - for example, if it returned +nan.0 for square roots of very small numbers.

Spend your energy on your application. (I don't want to get into why right now, but my book will have an entire section or chapter entitled Don't Use R6RS.) If you have some super-good reason for wanting to use R6RS, a few more comments... All I really wanted was the mod0 function from r6rs, which I can get without causing any further problems doing: (require (only-in rnrs/base-6 mod0)) The particular problem you're having is due to rnrs/base-6 wanting to use mutable pairs, while libraries implemented in Racket want to use immutable pairs. They *could* be made more interoperable, but all the ways I can think of would have other undesirable costs, and you'd either end up getting bugs in other places or get really lousy performance. I guess I was under the mistaken impression that all this stuff was compatible with each other. I can live with that not being so, but it seems that it might then be a good idea to include some of the functions that r6rs has, but racket doesn't, in some other module. As a workaround if you *really* want to use R6RS, but also use regexp-split, is to make a tiny #lang racket/base module that wraps Racket's regexp-split to convert any pairs in the return value to mpairs. BTW, if you want to parse input like this from a port, you can use Racket regexp operations or a grammar-based parser directly on the port, rather than reading a line and then doing a regexp-split on the line. The latter way is a Perl idiomatic way of parsing a language like this, and that way will also work in Racket, but there are arguably better ways. Thanks, I had no idea.

I think you need to add `(send grid refresh)' to the admin's
`set-focus' method.
It's funny that you mention this `set-focus' method, because I can't
find it in the docs, although my code seems to think it's a canvas%
method (oops?). I hope my confusion isn't contagious. ;P
Calling `refresh' of either the display or the editor in the admin's
on-focus works beautifully though, thanks.
Calling `on-focus' doesn't make an editor request a refresh, so
the refresh is currently happening only when the caret is blinked
(which does cause a refresh request).
That explains it.
Another thing. How do you enable simple select/copy/cut/paste
behavior with standard key-bindings in an editor?
Apply `(current-text-keymap-initializer)' to the editor.
I'm kinda struggling with this one. What I came up with is:
(define default-keymap (new keymap%))
((current-text-keymap-initializer) default-keymap)
(add-text-keymap-functions default-keymap)
and then I do (send editor set-keymap default-keymap) for each editor.
Is that what you meant?

Another thing. How do you enable simple

Apply `(current-text-keymap-initializer)' to the editor.
I'm kinda struggling with this one. What I came up with is:
(define default-keymap (new keymap%))
((current-text-keymap-initializer) default-keymap)
(add-text-keymap-functions default-keymap)
The last line here is actually not needed and doesn't seem to do anything.
and then I do (send editor set-keymap default-keymap) for each
editor. Is that what you meant?
Yes, though I forgot exactly how the parameter value works.

Use `add-editor-keymap-functions' in addition to
`add-text-keymap-functions'.
Actually I was already trying these, but AFAICT they don't do anything.

I'm actually trying to create something spreadsheet-like. I'm using editors to manage(display/edit) cell contents. Although each cell(-editor) individually doesn't have a menu, when used in a complete application there probably will be menus, and I'm planning to check out what the framework provides.

Beware that, under Windows, `on-paint' is called before `on-size', which means that the state update in your `on-size' callback happens too late. I think it would be nicer if `on-size' reliably came before `on-paint' but it's difficult to maintain those kinds of guarantees across all platforms. One solution is to add a call to `refresh' in your `on-size' callback. Thanks for the heads-up.

[racket-dev] weird (memory?) bug using (dis)similar require mechanisms

Generally speaking, I dread keybinding-based discussions because it is impossible to make everyone happy (and usually only the unhappy people speak up :). It will probably get really quiet now then ;P. Still, I think you folks are right that changes need to happen. I've looked over various apps and the guidelines and whatnot and (yep, I buy the argument that 'Terminal and Safari don't follow the HIG so why should we?'.) so here's the changes I've just pushed. Mac OS X Windows : - renamed Close to Close Window (but kept the keybinding switchero-ness as is) Gtk: - changed the menus so there is only one Close menu (no Close Tab or Close Window); if there are multiple tabs, it closes the tab otherwise it closes the window. To close the window in the multiple tabs case, you have to use the close box (or maybe alt-f4 if the OS-level keybindings map it to closing the window). I think the distinction (between platforms) in the menu is mostly academic (both are good choices) and should IMHO be eliminated since it can only create confusion when people on different platforms talk to each other. But anyway, the test for whether the platform is Gtk seems to be faulty, because now I'm seeing the ``Windows/OS X''-style menu. The good news is that it's now working as you describe. All platforms: - changed New Tab to menukey-t - changed Run to menukey-r These are working. - changed Replace to menukey-shift-f This also seems to be working. I think FindReplace could be so much more useful though: Ctrl-F find-search-term-as-you-type instead of Ctrl-F search-term Ctrl-G, identifier renaming (ignore strings, symbols, partial matches), regular expression replacements, identifier regular expression renaming (lifts restriction on partial matches, by using wildcards to extend to full match). I'm sure other people have more/better ideas. Please let me know if you spot any problems. No problems, just work in progress (as is all software) ;P Thanks for working on this!

The empty space shouldn't be there. 2) Now uncomment the first commented line, the one that creates buttons and run again. The texfields are now narrow and instead of empty space there are now buttons. This case seems fine. 3) Now uncomment the begin/end-container-sequence lines and run again. Suddenly the textfields are wide again and there is extra vertical space in between the textfields and buttons.
