Defining locals or constants

[david bovill]

Is there an easy way to do this type of thing:

constant WorldRadius = WorldConstant/pi

local LocalVar = WorldRadius * 2
>


That is initialise a local variable or constant to the result of a
calculation. I can use a "preOpenStack" message to trigger a script.... but
this is not always appropriate and clumsy - is there a simpler way?

Wouldn't a function do the trick?

Not as far as I can see:

local SomeLocal = testFunction()

function testFunction
    return 6
end testFunction

Will not compile here?

Hi David,

What you want is not possible. You have to use a function and can't  
use this function to define a local variable in the way you want.

function someFunction
   return 6
end someFunction

Best,

Mark

Is there really any practical difference between these two:

local LocalVar = sqrt(10)

on openstack
    do  thingsthatneedthatvariable
end

and:

local LocalVar

on preOpenStack
    LocalVar = sqrt(10)
end

on openstack
    do  thingsthatneedthatvariable
end

If you could define and set variables like you can in many other
languages, those lines would have to run on preOpenStack anyway,
otherwise you can run into issues, where a handler is called before
the variable is set.

Yes - because I do not want to have to deal with the different situations in
which the handler is called, and initialise the variables properly. For
instance when I call a custom property of an object in another stack, which
may or may not be "open" - it could simply be loaded into memory. In these
cases I want the variable to be initialised when the script is called and
not necessarily when a stack is opened.

Well, you could do this kind of workaround I learned from Teresa Snyder:

constant WorldConstant = 25000
constant WorldRadius ="[[WorldConstant/pi]]"

on answerTenTimesWorldRadius
  put 10 * merge(WorldRadius) into tResult
  answer tResult
end answerTenTimesWorldRadius

Don't know if this makes it any easier or harder, but just providing an
option...

By the way, Ken, is a new 2.9 stackrunner on the way?

Ben-

Since bz #1241 has been sitting around in "New" status for over four years
now, I changed its severity from enhancement to normal. Maybe that will keep
it from falling off the bug radar.

C'mon team... it's not that hard to implement evaluation of rvalues at
compile time...

Hi Mark,

Sure, you are right, this bughancement should be fixed as quickly as  
possible.

Problem is, there are a lot of such bugs, such as the incorrect window  
bounding rects, non-functional SSL, a slightly messed up standalone  
builder, a broken revPrintField command, the almost-impossibility to  
create custom cursors, incomplete driver names and other problems with  
drivers, problems with serial ports, a failing getResources function,  
problems with copying backgrounds, and remaining problems with the  
debugger.

All these bugs are of the category "come on team, how difficult can  
this be?" and date back to 2003 and earlier. Which bug should be fixed  
first? More important: how to motivate RunRev Ltd to actually do  
something about this? Even the 1.5 year long beta testing programming  
didn't solve this problem. What to do?

Best regards,

Mark Schonewille

That is really a problem. Even though I am pretty happy with the 2.9  
release there are those little things that catch you as they do not  
work reliably / not as expected / not as documented or not at all. My  
special friend at the moment is SSL and I really pray to get that  
fixed. Don´t get me wrong I love the environment (even though with the  
game stuff I am pushing Rev to its limits by now, as the whole  
graphics rendering and audio stuff is falling short compared with  
other environments), so I am really curious what the future brings.  
Rev lets me do cool stuff, I appreciate that, however it could always  
improve.

All of mine, of course <g>

Seriously, though, I'm not so much concerned with getting this one fixed
since I do have workarounds for it. They're just awkward and I'd like not to
have to resort to them. But I *am* appalled that this bug (and others) still
has a status of "new" two years after it was confirmed (and even that was
some two years after I filed it).

Make it easier for the community to document, vote, comment and organise
these issues. As an example  - I would vote on this, but I find that either
due to the upgrade to 2.9 or the fact that I have not filed a bug report in
a few months - I've lost my login - it would take me 5 minutes to dig out -
but that's too much. Its just too many steps relying on limited feedback and
resources from RunRev - the list is really the only thing that works because
of the choice of Bugzilla and the lack of easy integrate feedback integrated
into the environment - a Revolution IDE should have "crowd sourcing" built
in.

How about adtoptin the 'tag cloud' metaphor that is popular with social
bookmarking sites. The 'hotter' the bug the more prominence it has in the
feedback interface. Hard to ignore something when it's jumping out at you in
36 point text!

Hey David -

I'm not trying to be confrontational here but 5 minutes to find your  
login info (which can be saved by your browser for future trips to  
QCC) seems like a small sacrifice to make in order to log information  
on a bug that is important to you.

I think that regardless of what improvements could be made to the  
Quality Control Center it is important to use the system that we  
actually have. It is by no means inadequate for the task at hand and  
can be used to get information to the development team on how to  
improve the product. I know from experience that the folks at Rev look  
at the reports and fix them when possible. And their responsiveness to  
reports in QCC over the last few months has greatly improved as well.  
I hope that just because there are some lingering bugs that may have  
the wrong status or haven't been publicly addressed people don't  
abandon the system entirely.

One more thing to add relating to this and the RunRevLive conference  
(excellent by the way) I just returned from earlier this week. I have  
never walked away from one of the Revolution conferences as confident  
in the company as I did this one. There were a number of people from  
the company there that we (the attendees) could stop in the hall and  
chat with about all things Rev. I think 2.9 created a lot of positive  
momentum for Revolution as a development tool and the company seems to  
be in a position to build on that momentum. If you have stuff you want  
to see fixed or improved then I think now is the best time ever to let  
them know about it.

Regards,

Yes I know - just being honest. I was in a meeting - and had a few threads
to reply to - I click to vote on the bug - bingo login not remembered by
browser - so I drop it hoping to come back later - still not done. If
Wikipedia or any crowd sourcing interface adopted that  interface the
database would not have got off the ground. I think it took me over 9 months
to realise Bugzilla even existed - its not in the IDE, prominently on the
web site, or links in the footer of the emails from the list - it is
effectively invisible to only those that are active developers. It is an
old-school marketing attitude to bury "bug reporting" under the guise of
"quality control".

Yes please everyone - use Bugzilla now as its what we've got!

Now where is my login....

Surely that should be 'invisible to every *but* active developers'? ;-)

I was about to suggest that Rev take a leaf out of Apple's approach in  
Aperture where you have 'Provide Aperture Feedback' item right there  
in the application menu, until I looked in Rev's Help menu...

Help>Support takes you directly to http://www.runrev.com/support/ and  
then the QCC is one of the main links. It's not quite as  
straightforward as 'provide feedback' or 'report a bug', but it IS  
there.
