Uninstalling Livecode

[RM]

Currently I have about 40 versions of Livecode installed on my Xubun tu 
system, with them all

showing up in the menu system.

This is giving my system "gut rot".

If I dig into the /home/.runrev directory I can manually delete the 
versions I don't want, but the
system still 'sees' those I have deleted, so they show up in the menu 
system.


Is there a way to remove all but the 8 versions I use (3.5, 4.0, 4.5, 
6.7.11, 7.14, 8.0.1, 8.0.2 rc-1 & 8.10) completely?

Re: [ANN] Release 8.0.2 RC1

[RM]

This was a bad case of "Richmond's Silly Buggers":

1. A cache on my Xubuntu system had suddenly had an attack of bloat so 
there was NO space left on my HOME partition; something I did not see

(because, previously, I had 1.5 GB space) before I attempted installation.

2. I messed around with the GRUB thing and booted into a recovery mode 
and managed to delete a few gratuitous installs to make space.


3. Subsequently no problems whatsoever.

4. Sorry for spoiling your day.

Richmond.

Re: OT: Pi tripod case

[Mike Bonner]

I'm working with some high quality test materials here at home first
(aka,cardboard and foamboard) to figure out what I want, and then will
tackle converting to a model.  As far as the 3d modeling goes, I have a
tiny bit of experience with blender, but know so little I might as well be
starting from scratch. (I did take an autocad 11 class LONG ago)  Tutorials
are in my future I can tell.

Re: Has anyone got to the end of the BMI Calculator example?

[Graham Samuel]

OK, I added a text file to 17812 describing my experiences. I heartily endorse 
the idea of a ‘back’ button! My narrative had to end when LC 8.0.1 refused to 
open any more property inspectors - no idea why. I also had to use the ‘fast 
forward’ button once, just go get some progress. It really does need to be more 
robust. I am still a long way from understanding widgets, I fear.

RE: OT: Pi tripod case

[Lynn Fredricks]

Shapeways prints are surprisingly good. I have visited with them previously
at SIGGRAPH, where they showed off prints using different materials and
metals.

You do need to model very carefully and specifically for 3d printing.
Remember how you were warned not to mix up color formats and image
resolutions before sending something to a professional printer - or you will
end up with a major surprise? Same thing or worse with 3D printing.

Re: OT: Once more

[Mike Bonner]

Ah k. I'll have to see if I can find a high power tp-link for this.  I like
the alpha i'm using now, but if a tp-link will work I can always add a
reflector or windsurfer antenna to get the range I'm hoping for, plus I
have a couple 9dBi rubber duckie antennas (and a 2.4 yagi, though it would
be a pain for what I'm doing) .  Another option would be to find a 5.8 that
will work since it will give better line of site distance, but I'd prefer
to stick with 2.4 since I can't guarantee the end user will have a dual
band wifi capability.

I guess the other option is I can just declare myself apple incompatible
since it works so well with EVERYTHING else. I'll have to borrow an iphone
or ipad and see if that makes it tank too.

I don't suppose you have the exact listing for the tp-link available?

Yes and yes. I have it now running on a Raspi 2B (and it runs also with the
on-board WIFI of Raspi 3). On Raspi 2 the fix was to try all WIFI dongles I
could find in my workwear  ;-)
Using a 'newer' TP-Link fixed everything.

I'll check out adafruit, I haven't looked there in a while.  I'll also
check servo city to see what kind of things might trigger ideas.

One way to capture a nut?  Give me a project.  Keeps me busy for months.

Re: OT: Pi tripod case

[Mike Bonner]

Yeah, I'm thinking a hex socket to fit the nut (external socket, so full
piece thickness can be maintained for strength) then I have this handy
paste stuff that is used for glass bedding.  I can coat the nut threads to
keep them clear and paste it in.  Having decided to design a case mount
rather than a case, it should be considerably easier now.

Re: OT: Pi tripod case

[dsc]

Do you get stuff from AdaFruit?  They sell a 3/8 to 1/4 adaptor that some 
people screw into a simple tight hole in a 3D design with glue to make a strong 
1/4 thread.  I think you can also do this with some laser cut pieces but with 
acrylic you have to be careful with the hole size because it might crack.  I 
have also seen some press-in (heat or force) for laser milled pieces that I 
have seen described online.  You might need to get those from--arg--that place 
that has all the cool hardware.  You just need to choose material carefully.  

With the laser cutting you can adapt a box design and you would use (say) 
InkScape or Illustrator instead of TinkerCad (for 3D).

OT: Once more

[Mike Bonner]

One more OT question if I may.  My current project uses a pi with a long
range wifi dongle (an alpha), and hostapd so that the pi acts as an access
point.  Everything is working great.. Except when i try to connect with my
mac.

I had at first thought that the wifi was drawing too much power from my
battery pack and when I tried to connect it shut the pi down, but it
appears that is not the case. I can connect from various windows machines,
from linux, from android devices.. I can't test with IOS unless I borrow
hardware to do so, but everything I've tried EXCEPT the mac connects fine.
(If it was a power issue a y cable adapter would have solved it, but
noo)

Unfortunately, when it decides to crash on connection from my mac, it does
it with extreme prejudice.. On reboot I haven't managed to find any logs
telling me WHY.  (I may be able to change how caching works so that there
are no delayed writes.. maybe that will help)

Has anyone had trouble connecting to a pi that is running hostapd with a
mac?  And if so, was it fixable?

Re: OT: Pi tripod case

[Dar Scott]

TinkerCAD even has a thread generator.  It might be able to do the 1/4-20 UNC 
for the tripod.  I'm not sure how strong the threads will be.  

You might want to consider laser milling a modified case design that is 
available to make room for mounting and gluing on a nut.  You can etch the 
surface around the hole to help with gluing and maybe 
to control it.

Re: OT: Pi tripod case

[Mike Bonner]

Hey, that's nifty. And reminds me that I don't have to design a whole case,
I just have to design something that a current pi case can slip into that
has a tripod adapter. (which is easy since its basically a hunk of
something with the right size/thread nut, and a pocket to hold the pi)

I think I'll still go with a 3d print but just making a receptacle that the
pi will fit into with properly placed holes for cabling and tripod nut
brings it back within my fabrication abilities.  (Goes to get out the
dollar tree foam)

I could probably even do something out of metal. (I'm lucky, my dad has a
metal lathe, and recently rebuilt a mill from the ground up, so if I can
figure out what I want, he can help me with the fabrication)

Thanks for the help, I don't know why I was so stuck on having this be an
all integral case. It will actually work much better as a separate unit. (I
can design in a place to mount the external wifi antenna and a shelf for
the battery pack too)

I like the almost self-referential nature of this sentence.

Are you talking about editing?  Then I agree greatly.  I do get lost in 
structures.  I would appreciate the editor helping me.  I sometimes avoid deep 
nesting or many lines between structure boundaries by ending some error 
handling with a return or a throw.  Mostly, I try to find some meaning for the 
innermost loop and break that out as a separate function, especially something 
I can use elsewhere.  That lowers my need for block scoped variables, too.  (If 
I know the loop won't have a lot of iterations, I break down the content of the 
innermost into meaningful parts, too.)

So, I agree with editor help.  (Assuming I grok'd this right.)

LiveCode 8.0.2-RC1 contains *only* bugfixes. It is a maintenance release,
and does not include any new features.
LiveCode 8.1.0 DP1 is a development preview release, and contains new
features (e.g. new Windows player, updated standalone builder).

Every bug that is fixed in an older version (i.e. 8.0.2 rc1/rc2) will be
merged up into newer versions (8.1.0 dp1/dp2)

@Richmond
Could you please file a bug report? Do you see the same error when
installing 8.0.1 for "You only"?

Best,
Panos

Re: "LiveCode Infinity": lexically-scoped variables and bytecode blocks

[Monte Goulding]

What I think we could do which I personally feel would be a bug fix is if a 
variable is declared with an initial value then reassign it if we iterate over 
the local command again.

For example:

repeat 
local tIndex = 1
-- tIndex is always 1 here
repeat
add 1 to tIndex
end repeat
end repeat

FWIW, http://quality.livecode.com/show_bug.cgi?id=17813#c3

Here's Ali's comment in full:


Here is the pull request:
https://github.com/livecode/livecode-ide/pull/1192

Essentially the problem was that the 'frame behavior', which unifies
all of the palette header and footer handling, assumes that there is
a 1-1 mapping between preference menu items and preferences. The
original implementation of PB ordering used two preferences for each
menu item (sort type and sort order for each of stack, card and
control), which meant that the frame behavior couldn't set the
checkmarks correctly.

Hence the fix was to combine each pair of prefs into one
(pb_stackSortOrder & pb_stackSortType -> pb_stackSort), add a mini
API for setting and getting the preference to make sure it was in a
consistent form, and then changing all the places where these pref
names were used.

Note I missed one instance, hence bug 17769, which will be fixed in
8.0.2 rc 2 (but not 8.0.2 rc 1 and possibly not 8.1.0 dp 2). The fix
for that is here: https://github.com/livecode/livecode-ide/pull/1222

I also took the opportunity there to add tests for each of the
ordering types.

OT: Pi tripod case

[Mike Bonner]

I'm looking for a decent pi camera case with a tripod adapter on the bottom
(so that pictures are correct orientation without worrying about rotating
them)  Since most cases are set up so that correct rotation is attained
with the usb cables poking out the bottom, the case would have to use an
offset adapter of some type for my wifi dongle to poke out the bottom.
(cabled dongle, so there is some flexibility (no pun intended) as far as
clearance goes)

I have a project pretty much done (with lc server/picam on the pi being
remote controlled long distance by an lc application grabbing snapshots)
but having a more functional casing option will make a huge difference in
the final product.  A custom print with a hole to cement in the right size
nut, or with a threaded hole would be fine, but chances that I'll ever own
a 3d printer is slimmer than none.  Plus my fabrication skills for this
sort of thing aren't so good, so I guess i'm looking for an affordable
pre-made, or affordable 3rd party that can print a few cases for me.


Suggestions?

It all depends upon what you are doing.

I, by necessity, have layers of nested loops.  Not being able to exit an
outer loop (or, for that matter, to identify the companion beginning of a
control structure, takes odd contortions for the first and several minutes
at a time for the second.

Strong typing, even optional strong typing, would be a speed advantage when
repeatedly handling math, for example--if theVals[] will only hold integers
(e.g., pennies), and I regularly sum them, it's simply faster for the code
to know that they're integers instead of converting them.

And when you have not alternative but 10K+ lines of script, and handlers
that are unavoidably several hundred lines, being able to localize
variables is a Godsend; you don't have to worry about whether you used the
same obvious name elsewhere, and whether you'll get side affect.

Re: Has anyone got to the end of the BMI Calculator example?

[Mike Bonner]

Yeah, I forgot that.  You actually have to go into custom colors to set the
rgb values, but it would be clear as mud to someone who has never done it
before.

Definitely add to it.. If the tutorial tools can be fleshed out and made
easier, and more complete (hopefully with full storyboarding?) it would
help encourage a multitude of creative uses.  (It might even be useful in
detailing "bug recipe" walkthroughs, as well as hopefully a way to include
tutorials in standalones.. I'd LOVE to include tutorials in at least one of
my standalones.  (Lots of turnover at the place that uses this particular
application, and whlie its simple, having a tutorial walk a person through
the steps would be really great)

Re: "LiveCode Infinity": lexically-scoped variables and bytecode blocks

[Dar Scott]

In LiveCode, I tend to use small private functions.  In a twisted sense, a 
handler that calls those does have block-based lexically scoped variables, the 
block is just pushed into a separate function.  

On those occasions that I do write long handlers (for whatever excuse), I 
sometimes pretend that variables are block scoped for documentation reasons.  I 
declare the variables right before the section they are used in.  This might be 
confusing for others reading my code, though, so I minimize this.  

I also use 'it' as though it has block scope and try not to let its life go 
beyond the chunks of a handler as my brain sees them.  Clear use of 'it' often 
avoids the need of a variable.  (Though a variable with a good name helps with 
documentation at times.)  

So, for me, other improvements in compiling without language changes are more 
important.

Dar

Well done Mike for getting your report in so quickly. I intend to add to it 
with a narrative of what I saw (on an iMac with Yosemite 10.10.5 running LC 
8.0.1). I hope that Peter is right and that it’s all one problem, although 
there are other niggles than the guidance system - for example, when one is 
told to set colours, it would not be clear to a newbie that these are RGB 
colours, since the colour palette offers several alternatives and RGB probably 
doesn’t come up first… hoping to get on to my narrative soon.

So are things such as strict compilation, case dependency, and the like
(which I think should be defaults, but . . .).

I do see lexical scope, named control structures, and the availability of
strong typing as absolutely critical for the longterm (even to the level of
being a a go/nogo issue).

Looking for suggestions on how to approach this...

[Glen Bojsza]

Hello,

I am looking for a way to cycle through a large list of urls and capture
the home page and the about page (if it exists...some sites don't have one)
using LC 8.

My desired output would be a single pdf file per url.

Is LC 8 a good solution since I will need to do this on a regular basis and
each list may become a couple of thousand urls?

Can revBrowserPrint be used to output a pdf directly?

The ideal solution would be to feed a list of urls and the app would start
working on producing pdfs (using the url excluding the domain as the name
for the pdf).

Any suggestions on this would be great.

thanks,

Glen

Hi Mike,

Since, as far as we know, these are all directly related to the same 
feature and can likely be fixed together, please just file a single bug 
report (and someone will split it up if necessary).

Re: Has anyone got to the end of the BMI Calculator example?

[Ali Lloyd]

If you are having issues with the tutorial it would help a lot if you could
say:
1) What platform you're on
2) What stage of the tutorial you got to before it got stuck
3) How you're stuck specifically
  - Does the instruction window not appear at all?
  - Is the instruction window hidden behind another window (probably a
palette)?
  - Is the *target* of the required action missing (eg no tools palette to
drag an object from, no property inspector to change the property, no
dotted-line guide to show where to place an object, no object to
click/place/select)?
  - Is the instruction satisfied (as far as you can tell) but the tutorial
has not moved on to the next step?
Thanks,
Ali

Re: Has anyone got to the end of the BMI Calculator example?

[Graham Samuel]

Thanks - doesn’t always work for me. The thing has actually got into a loop 
now… telling me to edit some script but not apparently letting me do it. I’m 
tired of this. I REALLY want to understand LC8 and my next step was to see if I 
could adapt an old desktop app of mine to HTML5, but right now there are too 
many concepts I haven’t grasped so I can’t start. Grrr.

Re: Has anyone got to the end of the BMI Calculator example?

[Mike Bonner]

The secret for me (which shouldn't be necessary) is to drag whatever
control/palette/whatever is being referred to by the tutorial and it forces
a redraw of the tutorial part itself, at which point I can get to the next
step.

Re: "LiveCode Infinity": lexically-scoped variables and bytecode blocks

Lexically-scoped variables are completely incompatible with the current 
execution model of LiveCode Script.  If you changed it, it would be from 
many perspectives a different language.


I believe that Mark Waddingham has a plan, at some point in the future, 
to change the LiveCode engine so that LCS is _also_ compiled to bytecode 
and run in the same VM that LCB is.  Because variable scope is 
determined at compile time, you could then have multiple "versions" of 
the LCS language, which could all be run simultaneously and interact 
with each other without any problems.  However, this would be a huge 
project (in fact, the project is, fundamentally, the long term "Open 
Language" goal).

Re: Has anyone got to the end of the BMI Calculator example?

Hmm - looks like confirmation that the example (well the guidance really) is 
not robust. Since writing my email I did get a bit further by what amounts to a 
process of random clicks, but now I’ve reached “resize and position the graphic 
as shown” when nothing IS shown, so stuck again… very frustrating.

To have this in livecode itself is on my top 3 list . . .

Has anyone got to the end of the BMI Calculator example?

[Graham Samuel]

I’m still trying to get a handle on LC8, and I now have LC 8.0.1 on my Mac, 
which AFAIK is the latest stable release. But I still can’t get the BMI 
Calculator example to work all the way through - the guidance has abandoned me 
at the first field, and the ‘fast forward’ arrow doesn’t do anything.

Has anyone got to the end, and if so, how did they do it? I know I am very much 
behind compared to all you LC 8 aficionados, but I am not yet convinced that I 
really understand what a widget is, so I need to see a whole working example to 
understand how widgets have changed the LC that I have been using for so many 
years.

Can anyone help, or maybe suggest an alternative practical learning strategy - 
or shall I just tinker around until the fog clears?

TIA 

Graham

Peter,

LCS and LCB code is generally human readable (to the extent of the
knowledge of the reader). Bytecode is much less readable. Is LiveCode,
Ltd or the Open Source effort doung anything to screen for Widgets with
malware hidden in blocks of byte code?

Re: How to change the color of the text in a disabled button ?

[dunbarx]

Why not use two b buttons. The colored text one would not be opaque, and have 
no border. Simply overlay the two with the colored one on top visible when the 
other is disabled.

"LiveCode Infinity": lexically-scoped variables and bytecode blocks

[Peter TB Brett]

Hi folks,

Just a quick update to let you know that work has already started on the 
"LiveCode Infinity" improvements to LiveCode Builder.


There are two really interesting things that will be finished soon.

Variables in LCB are going to become lexically scoped 
(https://github.com/livecode/livecode/pull/4113).  This means that 
variables declared inside an "if" or "repeat" block won't be accessible 
after the end of that block.


if true then
   variable tVar as String
end if
-- tVar isn't accessible here

This also means that if you have a "repeat" loop, the variables that are 
declared inside the loop will be automatically reset on each iteration. 
It helps avoid bugs where temporary values created inside a loop get 
carried over to the next run of the loop.


   repeat 5 times
  variable tVar as optional String
  -- tVar is reset to "nothing" every time the loop runs
   end repeat

If you wanted tVar to be preserved from one iteration to the next, you 
can simply move the declaration outside the "repeat" loop.


Finally, it means that you can now "shadow" variables.  For example, 
this will become valid LCB code:


   variable tX as Array
   repeat 5 times
  variable tX as Number
  repeat 4 times
 variable tX as String
  end repeat
   end repeat

The second new feature is the "bytecode" block 
(https://github.com/livecode/livecode/pull/4097).  This lets you write 
blocks of raw LCB bytecode in your LCB source files.  At the moment 
there are not very many places where this is likely to be useful, but in 
the future when we add more bytecodes (as part of the "LiveCode 
Infinity" project) bytecode blocks will let us write much more of LCB in 
LCB.


I believe that "unsafe" blocks and "unsafe" handlers will be added soon. 
 These will be used to mark code that does risky direct memory 
manipulation.


Peter

Yes, a group of two images used as icons will do the trick. But it is rather 
boring to do that for a zillion of buttons… not counting the different 
resolution for different screens.

Re: How to change the color of the text in a disabled button ?

[RM]

That's all rather odd as the text in a button, regardless of what the 
textColor is set to goes grey

as soon as it is disabled.

If one groups the button and then disables the group the button text is 
also greyed out.


If one takes a snapshot of a button and then uses the resultant image as 
a button that, also, won't

do any good as one cannot DISABLE an image.

Thanks Ali,
Pretty sure I signed the agreement so we are good to go.

Will hopefully be back in a day or two with a QQC link.

Hi James,

Q1 - yes, that's fine by me, as long as you've signed the CLA
http://livecode.com/store/account/contributor-agreement-signup
(I'm not going to make too much of a habit of committing things on other
people's behalves, but the datagrid docs are important and I really
appreciate the time you and Paul have taken / are taking to help with this)
:-)

Q2 - we don't currently have good 'support' for combining sub-guides into
one, so at the moment I'd prefer just one markdown file if that's ok.

Q3 - I think that's a sensible approach, yes!

OK the bug bit and I thought, why not.

I have begun to convert the DG Manual to markdown.

It is actually fun (I know, I need to get out more.)

I have converted the first two chapters (66 out of 230 pages) and before I
move on have a few questions.

The first is for Ali: Can I submit a zip of the files in a bug request to
pass them over too? Modifying something on GitHub is one thing,adding all
this is another.

Actually the second one is for Ali too: The images will all be in a folder
called images (for insertion into the existing folder) but how many markdown
docs should there be. A single doc would be very big. I am thinking along
the lines of one doc per chapter. Thoughts?

Q 3. Currently the images used are all pre LC 8. I was thinking of using
these first up and once everything done and dusted (and up on Github) go
through and update them to LC 8.  Yes?

information about 32/64 bit. But QT is running fine on this machine and I
haven't had any complains about Mac users up to now. What does this mean?
Where can I check, if my system is running in 32 or 64 bit?

Apple have no longer support QuickTime on Windows and it is deprecated on
OSX; it has seen no substantial changes since the release of AVFoundation in
OSX 10.7. Additionally, it has never been available to 64-bit applications
on any platform. Apple strongly encourage all apps on OSX to use
AVFoundation instead of QuickTime.

LiveCode pre-8.0 was a 32-bit only app and wasn’t directly affected by the
deprecation of QT. However, since 8.0, we have also offered a 64-bit
version, which offers performance improvements and, in future, will allow
increased functionality (many interesting frameworks on OSX, like MapKit,
are 64-bit only). Basically, 64-bit is now the norm on OSX and 32-bit no
longer sees any new features from Apple. By default, the IDE runs in 32-bit
mode (it can be switched to 64-bit mode by changing the app’s properties in
Finder). Standalones can be built to include 32-bit mode, 64-bit mode or
both; if you select 64-bit mode, QuickTime will not be available.

The DirectShow framework that the new player on Windows uses supports
user-installed codecs; if your users were to install a Sorenson decoder,
they would retain the ability to play your videos without you having to
re-encode. As far as I can tell, the decoder is proprietary to Sorenson and
is not something LiveCode can supply; you may have access to it as part of
your Sorenson compressor, however. 

Unfortunately, AVFoundation does not support installing additional codecs
and does not support the Sorenson codec. For this reason, we maintain the
ability to use QuickTime in 32-bit mode on OSX (even in 8.1) but there is
nothing we can do to make it work using AVFoundation or in 64-bit mode.
Apple could remove QuickTime entirely in some future OSX. If re-encoding
your videos is a major undertaking, it might be better to start now in
readiness for when QT is no longer available.
