Re: Line numbers for soft-wrapped styled text?

[hh via use-livecode]

The solution of Alex T. was the first example I saw of a useful
usage of the styledText array. TMHO this is the way to go for the
future of more and more complicated styled text.

As was said elsewhere, there could be a considerable speed up if
first the visible range of lines, say numbers L1 to L2, is determined.

We had once a thread in the forum about that. The fastest method:

Compare the formattedHeight of line 1 to L of fld T to the vscroll v0
of fld T. Not by walking with L up from one, but by using a binary
search for L1 and then starting from there to find L2 by comparing to
v0+the height of fld T. This needs only a few millisecs even for large
chunks.

Then use Alex's method with the styledText array of these lines. Or,
quick and dirty, save the selectedChunk, select before each line L
in the range L1 to L1 and collect the selectedLocs and then restore
the selectedChunk.

Now draw the line numbers each into an own freshly created field or
use Alex's space below method.

p.s. Hopefully you will share your final code.

Re: Object Selection Handles

[Craig Newman via use-livecode]

A lesson should be taken from any CAD program worth its salt.


Handles are ALWAYS rectangles for objects, and always within the bounds of the 
object in question.


That said, a group might be an exception, since handles would overlie the 
controls at the extreme corners of a group, and that looks and feels wrong.

My understanding is that only a group can do that, not a button

if there is group snoozle on cd i of this stack then

else

place group snoozle onto cd i of this stack

Re: Line numbers for soft-wrapped styled text?

[Alex Tweedly via use-livecode]

What a cool idea !

In fact, could you not simply do
   set the liststyle of line 1 to -1 of fld "mytextfield" to "decimal"
and then unset the liststyle whenever needed (e.g. when the field is 
subject to  copy, save, etc.)

Very minor drawbacks for my needs are aesthetic:  I prefer a line 
number field without trailing decimal points ("1" rather than "1." as 
LC's listStyle renders), and that line number be left-aligned by LC 
renders its list line numbers left-aligned.


But overall quite nice, and very snappy. Thanks, Jim!

Blowfish digest , how to create in Livecode

[Matthias Rebbe via use-livecode]

Hi,

i have a MySQL DB which uses passwords  created with php crypt function using 
blowfish

the php code looks like this for example

$salt='$2a$08$NWy7XidPPL2XEsouCG3dy’;
$digest= crypt(‘myPassword01’,$salt);

how can i do this in Livecode server? I find SHA1digest and MD5digest functions 
in the dictionary, but no blowfishDigest function.

Or isn´t that possible in LC?

As I'm currentl refershing my 'web-knowledge' I made a demo.

An overlay by a LC window. You can set its transparency and could even
use this technique to make windowshaped 'overlay-stacks' (so that you can look
through and click through the 'holes' of that stack).

Widget usage example #3
http://forums.livecode.com/viewtopic.php?p=152773#p152773

It's not perfect, you will have to add scripts, but the HTML is fully included.
Stack size (incl. browser widget and HTML+CSS+javascript) < 30 KByte.

May be this is not really what you want, but TMHO an overlay by a lot of single
objects will slow down the performance of the video dramatically.

Re: where does the standalonebuilder saves the substacks in an Mac OS App?

[J. Landman Gay via use-livecode]

I think that's right, Apple enforces this rule.

The standalone builder will move files to a Resources folder when it 
builds the app. For backward compatibility, scripts that reference the 
engine folder are redirected to the Resources folder automatically.

To my understanding, it's a requirement in accordance with Apple's

old location where the actual application binary resides, but in the
new location they can.

As an administrative user I am able to copy files to both locations,

That is my understanding at least. I've not dug in enough to know for

Object Selection Handles

[Dan Friedman via use-livecode]

Greetings!   Is there a property to change the shape of the selection handles 
when using the selection tool?  In LC 9 (and 8), they are round circles that 
protrude outside the edge of the control.  In previous versions, they were 
squares that remained within the rect of the control.  These large “dots” make 
it hard to do fine alignment of controls.

I know there is a selectionHandleColor property, but is there anything like a 
selectionHandleShape property?

Also, the border of the selected control is dashed when selected.  Can that be 
removed as well?

Thanks in advance,
-Dan

Re: where does the standalonebuilder saves the substacks in an Mac OS App?

[Bob Sneidar via use-livecode]

To my understanding, it's a requirement in accordance with Apple's sandboxing 
policies, if you want an executable to be able to make changes to files inside 
the executable bundle. The way it's supposed to work, no application is allowed 
to write or modify anything in the old location where the actual application 
binary resides, but in the new location they can. 

As an administrative user I am able to copy files to both locations, but 
sandboxing is not about folder permissions. It's about executable permissions 
and it's baked into the OS so no one can (ostensibly) change it. 

That is my understanding at least. I've not dug in enough to know for certain.

Re: Retroactive background behavior

[Craig Newman via use-livecode]

Hi.


You cannot make a button with backGround behavior, only a group. And even with 
a group, you would have to place it on all cards explicitly if you had not 
created that backGround group at the beginning. The automatic placement of a 
group on new cards has to be in place before those new cards are created.

As I recall there is a method of retroactively creating a button with

How is my recollection?

The textChanged message is only sent when changes are made to the text 
of a field.  Changes to styling attributes may also affect line heights 
and wrapping (e,g, bold will increase text width, textSize will enlarge 
it overall), and those changes are beyond the scope of triggers for the 
textChanged message.


That said, I don't believe there are any messages for style changes, so 
I agree a frontScript here trapping multiple message should not be 
needed/useful.


AFAIK the only way to account for styling changes is either in the 
scripts for the UI elements that enact them (which is what I'm using 
now) or polling (which I generally try to avoid unless I have no other 
way to solve a problem).

if you don't care? I have an old application just migrated to LC 8, where I am 
running an independent stack file in that old dir("Contents/MacOS"), and it is

Is there any Apple link about that or are there any informations, into which

Yes, Apple required that change a while ago.

Here's what I've got (lazy default values):

I may at some point change the RBL setting because I hate RBLs, but

I don't think that's it. I've had time codes displays running before, achieved 
in this way, so something that normally works, doesn't. I haven't worked out 
if this is an issue with 8.1.3 or another side effect of the particular movie. 
Or just that working late on a small screen, I made some other stupid mistake.

I took a similar approach for now - rather than playing the movie and then 
catching the currenttime, I used my timer to keep setting the current time, 
moving it on a frame at a time (in fact for now I wanted to export a timelapse 
of the movie anyway, so was happy to jump it along half-a-second at a time). 
But in my ideal world I'd have this working interactively, including allowing 
the user to scrub the movie to a different time and have the data graphics 
update as they did.

That's what I don't know yet! Obviously it's not enough that it's a .mov 
instead of a .mp4; when I exported it, the movie also changed codec, 
resolution, framerate... (partly because I was in a hurry so I decided to work 
with a smaller lighter version to make progress). I'll need to try some 
experiments with changing fewer attributes to find out which is the crucial one.


What are the characteristics of the movie you tried it with, that didn't work?

Hi Ben,

To try to answer the second part of your question first.

it’s showing each frame quickly so your eye tells you
it’s a movie.

One solution I had to use in the past to make a decent
animation was to break the movie into each frame and
then put each frame onto each card.  I had a short
movie so it ended up being 254 cards.  It was for iOS

Then I was able to have a graphic which appeared

The first, which drove me somewhat mad until I found an out, was that the video was 
always displayed on top of other LC elements - graphics, fields. This is using a player 
object; I found that the controller would be rendered correctly layered among other 
objects, and indeed would obey blending levels; and occasionally in tool mode the video 
frame would also; but once I switched back to browse mode and played the video, it 
invariably displayed on top of everything else, at 100% opacity. Toggling the 
"buffer" property did not appear to make a difference.

The second problem - which I also found frustrating because I'm sure I've done 
something similar before without this arising - was in triggering the updates 
to my overlay graphics. I thought that I could have a timer sending a regular 
message to my code which would check the time of the movie, and adjust graphics 
appropriately. The code worked but I only saw an update twice; when the movie 
started, and when it stopped. As far as I could tell this wasn't an issue about 
the screen not updating; but that the message genuinely wasn't sent while the

Well, yes - it is just displaying the glyph completely out of context.


Now what is interesting is that LC 8.1.3 on Mac OS 10.7.5 will NOT
display characters simply as
characters, but tries to be too clever for its own good.


No - it is not being too clever. It is doing precisely what it should 
for the purposes of laying out text (and indeed what the CoreText engine 
on MacOS does - as that is what the engine uses). Pretty much everyone 
writing apps does not want to care about the (very complex) details of 
turning text into positioned glyphs, they just want a text string to be 
rendered how 'you would' expect, with regard to the codified rules which 
have been developed over a large number of years for typesetting 
language into a printed representation. Moreover, generally people want 
that done in a way which is 100% consistent with all other apps on the 
same OS (which is why using system services for such things is so 
important - Windows, for example, has a lot of behaviors built-in for 
dealing with CJK fonts which date back 1-2 decades, if an app doesn't 
support those then it won't operate in the same fashion).



As I am the developer of a program that does "all the knitting"
internally all I really would like is exactly
what this chap describes above. The fact that LiveCode seems to be
doing some of "the knitting" off
its own bat and/or leveraging OS "knitting" is what is causing me 
problems.


Quite - you have a special-case - you don't want to layout text, you 
(probably) just want to render glyphs which you specify.



I have already run the latest builds of my Devawriter on Mac OS 10.12
and Ubuntu 16.04
without these problems.  However I have several clients who run their
Macs on Mac OS 10.6.


Well, it is unlikely that anything will change with regards 10.6 with 
regards LiveCode. 8.1.x will be the last branch which will support 
anything less than 10.9.


To be fair, 10.6 is pretty much now a completely dead operating system 
for anything other than offline use. Critically, it does not and will 
never support some new SSL related transport modes, nor does it get 
Certificate Store updates. Basically, as time goes by the number of 
things a 10.6 machine will happily connect to *safely and securely* 
'over the internet' will diminish to probably zero. (I know this from 
experience - my laptop is still on 10.6 for various reasons and is just 
about unusable now as it can't be used to connect a variety of online 
services anymore - updating it to 10.11 or 10.12 is on my todo list).


In regards to your specific requirements, I had a thought on that last 
night. I think essentially what you want is a way to treat a sequence of 
codepoints in a field as a sequence of glyph indicies into the current 
font. So rather than treating the 0x1CF7 codepoint as a character, it 
would just be treated as a number to index into the glyph table of the 
(inherited) font set on its style. This could be done as a textStyle, 
although that would give you no control over positioning, the only thing 
it could do there is use the advance width / baseline in the glyph to 
position it sequentially.


Warmest Regards,

Mark.
