Re: [opensource-dev] I could use a little help with boost and callbacks and stuff

[Ricky]

IIRC that _number thing has to do with iteration.  The example code I
gave in the email here passes one parameter (myParameter).  I'm not as
strong with Boost or the Standard Lib methods as I was a couple of
months ago, but I don't recall there being a no-parameter version.
The count of parameters is entirely dependent upon the function/method
being passed.

I discovered this technique online after searching the 'net looking
for how to work with functions and methods as first-class types in
C++: I wanted to pass the method of a class instance off to another
function (in my case, a template) so that is could call it in a
centralized manner.  I was able to do so this way, though it feels a
bit hackish - like a lot of C++ I'm afraid. (Yes, C++ isn't my fav
language, but D isn't what we are working in.)

Sorry I can't help much farther: my experience is limited, and my SL
viewer hacking experience is even more limited!

[opensource-dev] VD Build Page Hacking

[Ricky]

I finally got so annoyed with the build page that I decided to do some
hacking on it.  Turns out that the reason why it isn't displaying
changesets or JIRA entries is because the JSON format was changed
without correcting the Javascript.  What's more, the JSON information
doesn't have the needed data anymore.

So.  I dug and I hacked, and I hacked and I dug, and voila, I'd mashed
up a facsimile of what I think it did in the past.  And yes, I used
the phrase "mashed up" on purpose: the page I built taps into
BitBucket's REST API to get the missing data.  It's not all that
pretty to go that route, but it works.

Here's a demonstration: http://rwcproductions.com/~ricky/snowstorm/
And here's the patch:
http://rwcproductions.com/~ricky/snowstorm/index.js.patch.txt

Yes, there are some whitespace changes, and render_description() could
be cleaned up further, but I tried to not affect more than the areas
needed to make it "workable."

Suggestions, thoughts, etc. welcome.

the ui element is doing fine, it's the "non-ui" class that I can't get 
to work with the buttons...

I'm trying to get Zi Ree's client side AO to work with toolbox 
buttons.

There's a class "FLoaterAO" which is basically the setup dialog, and 
that works fine after "buttonizing" it.

There's another class AOEngine which is the actual running AO, and 
that one needs to get two methods:

void AOEngine::Toggle() { toggles the AO on or off }

bool  AOEngine::isRunning() { returns true or false depending on the 
state of things }


I'm having trouble getting those two methods registered in the 
callback registry, so that I can use them in app_settings/commands.xml

Any help is appreciated!

LC
