Well, svnwiki is a wiki developed in Chicken, is actively mantained by and has a great "local" support from Chicken contributors (Alejandro Cuervo, Nelson Castillo), and has features convenient for the project (e.g., syntax highlight for Scheme code, subversion backend etc.). I don't know exactly what "Page Index" is, but my guess is that you want an index of all wiki pages. In this case, you can always get a local copy of the wiki repository (see http://chicken.wiki.br/svn%20checkout).

Not the client's fault, really. Windows doesn't allow double quotes
in filenames.
A Posix filename is any sequence of octets not containing 0x00 or 0x2F (/).
It may be interpreted according to any encoding.
A Windows filename is any sequence of 16-bit values not containing 0x
to 0x001F (controls), 0x007F (DEL), 0x005C (\), 0x002F (/), 0x003A (:),
0x002A (*), 0x003F (?), 0x0022 ("), 0x003C (<), 0x003E (>), or 0x007C (|).
It is always interpreted according to the UTF-16 encoding.

This may be of interest to GUI enthusiasts.
At least for me gtk2 is the one big missing egg!
The interesting part of the code, to me, is what is built on top of
the wrapped library. g+ is a very clean, Scheme-like GUI library that
keeps the fussiness of the underlying C implementation well away from
the Chicken code.
Here for instance, in g+, is a GTK OptionMenu object containing an
embedded button and a nested menu, with the signal handlers embedded
in the menu structure.
(g+option-menu
(g+menu
(g+menu-item "First"
(g+signal 'activate
(lambda (i) (print "Chose 1"
(g+menu-item*
(g+button "Hello"
(g+signal 'clicked
(lambda _ (print "Why, hello!"
(g+menu
(g+menu-item "hi1"
(g+signal 'activate
(lambda (i) (print "Chose 2"
(g+menu-item "hi2")))
(g+menu-item "Third"
(g+signal 'activate
(lambda (i) (print "Chose 3"))
This is an egg from code originally produced by Tony Garnock-Jones
(tonyg) in 2002. The code rotted a bit over the years, and I spent a
few days in January cleaning it up so it builds and runs on my Ubuntu
system. Tony G responded to my licensing request yesterday and
permitted me to upload the updated code. I've packaged it as an egg.
Great!
The main part of the code is a pretty straightforward wrap of libgtk2
and libglade. The only unusual thing is that a bespoke wrap program
is used instead of SWIG, and relies on "defs" files that are published
by the (Python) PyGTK project.
I have no experience with writing glue-code, just curious. What's the
advantage over SWIG? Does this approach make it easier to stay compatible
with new gtk versions, since PyGTK is guaranteed to be?
This egg is NOT related to the gtk egg produced by Alejandro Forero
Cuervo and Manuel Alejandro Cerón Estrada. That other project was
based on SWIG bindings and seems to have stalled.
There are issues with this egg as it stands at present. It is
definitely not usable for anything serious yet.
Firstly, libgtk+ is absolutely huge and this is an attempt to wrap it
all. The build process is an absolute beast and takes ages to run on
my system. It should probably be split up into bite-sized chunks.
On my system (1.73GHz Pentium M, 512MB) it took 3 1/2 minutes
to compile. Compared to the xlib egg it's a snap!
There are UNIX dependencies in the build process, most notably the
shell script "extract-all-types" which really should be converted to
chicken.
Attached is a drop-in-replacement for "extract-all-types".
Additionally the script excludes "gdk_window_get_type".
Otherwise i get this compile error:
wrap.c: In function `code_2':
wrap.c:53: error: too few arguments to function `gdk_window_get_window_type'
I guess for the same reason "gtk_gadget_get_type" is excluded in the
original version of "extract-all-types".
There are also probably some strong gtk-2.0 version dependencies. It
builds on my Ubuntu system with Ubuntu's stock gtk 2.8.20 build. It
also expects libglade. I cannot make promises about which other
versions of GTK it will run on, and if you want to build it without
libglade support you'll have to tweak the code a bit.
Besides the error mentioned above, it compiles against my gtk+ 2.10.6.
However most sample-apps crash:
> csi gtk2-explore.scm
Version 2.5 - linux-unix-gnu-x86 - [ dload ptables applyhook ]
** (gtkchicken:3545): WARNING **: Unknown gtype in gtype-from-name: GtkTreeIter

Error: unbound variable: gtk-tree-store-append
And so on.
However these apps do work:
gtk2-test-drawingarea.scm
gtk2-test-gobject.scm
gtk2-test-libglade.scm
The wrapping system doesn't correctly handle variable argument lists
with a NULL sentinel, despite the gtk headers signalling the usage
clearly.
Some of the demo programs fail mysteriously. Tony G and I think it's
a pointer wrapping problem, and I'll be working on fixing that.
Further bug reports would be most welcome. Please include details of
your system and the version of libgtk you're using.

Re : [Chicken-users] gui api design -- some thought -- long mail
A simple alternative is that often you just want to call yourself later. That is, register a timer which when it expires, will call the given function which you give when you register the timer. It can be a one-shot or a repeating timer. In my conception of the event queue, each event has a timestamp indicating when it has to be dispatched. So an event can be inserted in the queue before already present events. > b) (which is related) Since a function call results > from an event, you can't generate an event whose > callback needs the end of > the event-generating-computation (i.e. it's not > asynchronous). > > I'd rather like to finish a computation which generates > an event before processing it. If you generate the event and put it in the queue, it will be processed later when the code gets around to checking the queue, right? Yes. The code could be a scheduler (provided by the library) or user code. > c) Also, say you want to code "When the left mouse button > is pressed (elsewhere than above my two main widgets), > make the first widget be blue and the second one be red.". > (Call this the blue-red exemple for later reuse.) > You'll need to register a callback on the background widget. > This callback needs to access (to be aware of) the two > other widgets. I don't like this. Whereas in an immediate mode UI, the main "do" function is both finding out that the button is pressed, and drawing the blue and red widgets directly right? I guess so. An alternative way to get this behavior with callbacks would be to make it possible for every widget to register interest in any kind of event, whether or not it would seem relevant to that widget. The callback can have an extra parameter to indicate the relevance. So a normal button registers only for a click event on himself, and your special button registers for a click event anywhere, and is given a "true" when the click is on him, and a "false" if it's somewhere else, along with coordinates etc. Or maybe your special button does two registrations of two different callbacks so that the parameter is not necessary... The first part of your description sticks to my idea. Hwever, when you say 'the widget registers interest', I would say 'you register a callback that will only cares of one widget'. So to implement the button, I would make a handler for 'left-mouse-button-pressed which insert a new event, 'that-button-clicked.

That's probably a really good idea. I think in general the trend is that as memory gets cheaper (RAM and disk both, and I believe they will be the same thing some day when nonvolatile RAM is cheap enough), you can find reasons to keep data around, timestamp it, take diffs, even build a sort of version control system for some classes of data, rather than assume that only the latest, most current data is relevant and letting new stuff overwrite old stuff. Especially, any text which the user enters himself ought to be considered sacred and never garbage-collected unless the user asks for it to be deleted. The book "The Humane Interface" makes this point. I was thinking a few years ago that a computer's disk ought to be structured as a giant log, where the data the user creates is appended to the log, and then data structures which the software creates to organize that data never duplicate it - they just point to it. The user enters a stream of data, and the computer makes sense of it over time. You would have built-in version control - edits are actually a special kind of diff that is appended to the log, so you will have the new version and the old version at the same time. Like CVS or subversion but implemented more efficiently. That is what early versions of the Xanadu project were about...but there is more than one way to implement it, and I can't make up my mind which is the best one (and neither could the Xanadu guys, which is why it never got done). Anyway I'm not sure that mouse events have the same kind of perennial lasting importance that text does, but in graphical documents, like diagrams, a persistent history would be nice, with unlimited undo and the ability to compare different versions. I want to build something like that when I get the GUI stuff done. Interesting point. Although it was not clear, I was thinking of some functions to get events but also query the existence of a
Re: [Chicken-users] Centralized documentation
Just a few thoughts that I believe would be good to keep on mind on the discussion on centralized documentation: * Egg authors have the choice between using eggdoc or using the wiki. Originally all eggs used eggdoc and few started using the wiki as their authoritative repository. * When an egg uses the wiki, whenever a new version of the egg is produced, the HTML page is generated automatically from whatever is in the wiki. This page is uploaded to call/cc as well as included in the tarball * The process of generating the HTML page for an egg from the wiki only supports documentation stored as a single wiki page, but I suppose it would be easy to extend egg-post-commit to support eggs having multiple wiki pages as their associated documentation. * I kinda agree that it doesn't make that much sense to keep a potentially outdated documentation page in call/cc when it is also available in the wiki. Then again, I don't see this as that big an issue, since the pages in call/cc do begin with a disclaimer pointing to the wiki page. * It should be kept in mind that some documentation for the eggs should be included with them. For those with the documentation on the wiki, the best bet is probably to continue to do what we do now (include a render to HTML of whatever is available in the wiki when the egg is generated/uploaded). * Any improvements to the CSS used by the wiki would be more than welcome. :-) There.
