DataGrid2 - Improved Graphics Means What - Exactly?

[Sannyasin Brahmanathaswami via use-livecode]

The DataGrid 2 fund raiser is interesting, not so much for the DataGrid; which 
I don't use;

(Instantiating a small group template multiple times to make a longer grouped 
control is easy enough and scrolling list fields do the rest, so far there 
hasn't been a use case yet where Datagrid complexity warranted the ROI on using 
it. And the helper $ price tag doesn't help adoption. perhaps one day)

Meanwhile…Reading the text of the announcement carefully, still leaves room for 
wonderment,

What is the scope of the improved graphics rendering? Is It DataGrid only?

What about
1) other long grouped controls that need to scroll as one long group?
2) scrolling fields
3) scrolling list fields

Will they continue to "jitter/jerk" as they move? - that's how our users 
describe it vs standard mobile object "flow smooth as glass/water"

Does this initiative "cure the jitters"  for all scrolling objects?

In theory `the number of bytes of ` should in my opinion return 
whatever the byteLength function would given the codeunit docs state:

> The hierarchy of the new and altered chunk types is as follows: byte w of 
> codeunit x of codepoint y of char z of word …. 

However this report was resolved as not a bug so I guess that theory is wrong 
and maybe there’s a docs bug in there (I have asked internally on our language 
channel) http://quality.livecode.com/show_bug.cgi?id=13248 

put the number of codeunits of  “️” -> 3 

So this is actually 6 bytes but as documented you can’t rely on the codeunit 
length being 16 bit so I guess that means there is currently no way to get what 
you want reliably. Whether you need it is a separate discussion.

If you are dealing with bytes of binary data then use byteOffset. Is that what 
you mean here? Probably better to talk about ranges rather than substrings if 
you are discussing binary data.

Seems murky.  I'd much rather at least have something like a byteLen 
function, which returns the number of bytes for a given string.  With 
that I can maintain byte offsets into a file with good performance and 
no ambiguity.

How do I find a substring in binary data in a what that will tell me the 
number of bytes of the offset?

Some Unicode characters, such as emojis, have to be represented by two 
codepoints in UTF-16 (known as surrogates) so they take four bytes not two. 
Additionally, the number of bytes for characters with accents will take either 
one codepoint or two depending on whether they have been coded in pre-composed 
or decomposed form. (e.g. ç can be either U+0063 U+0327 (decomposed) or U+00E7 
(precomposed).

So it is isn’t easy to estimate the number of bytes in a UTF-16 string.

I would guess that LiveCode will store the characters of a string in single 
bytes if all the letters of the string conform to ISO-8859-1. So if you can be 
certain that your text is all ISO-8859-1 encoded, you can estimate at 1 byte 
per character. (The guess is base on the fact that the first 256 Unicode code 
points replicate ISO-8859-1).

Regards

Peter

You shouldn’t need to know. The engine will use native encoding where possible 
for efficiency. A lot of the performance improvements between LC 7 and 8 were 
using the right code paths based on whether the string is native or unicode.

If it’s text encoded then you probably want to use character offsets and let 
the engine worry about optimising it. If you know it’s binary data then use 
bytes.

How can we know which is in use for a given string?

Suppose I wanted to process a lot of text, so performance is critical. 
Using bytes would be optimal, since any chunk type or even Unicode 
characters may vary in length.


So if I wanted to create an index of byte offsets into a large chunk of 
text, how would I know how long a character is?

That’s true (the 16 means 16 bit) but internally strings may be either native 8 
bit or unicode 16 bit.

It should just be a direct memory copy so it’s about as efficient as you are 
going to get. If you don’t need the trailing chars it would be more efficient 
from a memory perspective to delete the remaining chars.

With many chunk expressions, I would imagine it does.  With line chunks, 
for example, the engine needs to walk through the string, comparing each 
character to CR, counting the found CRs as it goes.


But even then, better to have the engine do that in machine code than 
for us to do it in script. :)


In this case, though, I believe it doesn't need a loop per se, since 
AFAIK character are fixed-size entities internally (Mark Waddingham, is 
that true that UTF-16 gives us two-bytes per char across the board?).


If I'm mistaken there, any traversal of the string is still about as 
efficient as it's going to get in a general-purpose language, since it's 
relying on the well-optimized Unicode libraries many projects depend on.


All that said, as much as I enjoy benchmarking I wouldn't sweat 
use-cases involving small data.  1k chars could be sliced with any chunk 
type so quickly it probably won't matter.

I don’t think so. It’s similar to substring functions in other languages. As 
Mike said, string chunk expressions are one of the best things about LiveCode.

You can do things like:

  put char 5 to 25 of line 4 of tVar into tVar2

First 1000 characters without loop?

[Rick Harrison via use-livecode]

I have a string variable which contains over 2500 characters.
I only want to grab the first 1000 characters of that string.
Rather than looping 1000 times to grab each character
is there a way to just grab the first 1000 efficiently in
one big chunk?

I have been learning from Dans books
 since I started with
HyperCard, and I recently completed a project which uses his Quartum
PDFLibrary .  Saddened
by the news of his passing, he will be remembered.

AW: HD Windows Video Formats

[Tiemo Hollmann TB via use-livecode]

Hi Jeff,

I am working with H.264 mp4 videos for both Windows (directShow) and Mac
(AVFoundation), compressed with Sorensons squeeze. The drawback is, that
Windows 10 doesn't comes with a H.264 codec by default, so my users have to
install the codec. I made good experiences with the LAV-Filter codec pack.

Tiemo

Betreff: HD Windows Video Formats

Hi,

Just curious what video wrappers and codecs folks are using for HD (1080)
for windows 10 playback (surface) with the directshow drivers native now in
livecode.

its an odd set listed in the directshow format page

https://msdn.microsoft.com/en-us/library/windows/desktop/dd407173(v=vs.85).a
spx


wmv looks to work but has a 10mps max which has some issues with underwater
shots with lots of solids. the h264 compression option looks to be wrapping
in an mpeg2 and not quite sure of a path to get there. Does anyone do h264
that playback decoders installed under generic win10 install and a path to
how you made the files?

thanks

jeff reynolds

Could you expand on this a little bit? StandaloneSaving/Saved are only
sent during a build, so I'm not sure how I'd use those to intercept a
startup message.


Yes but they could be used at standalone building time (probably will 
require a little bit of reordering of processes slightly) so stacks 
could embed their resources in a stackfile.



Also, when do the externals actually load? If they load at startup
before any messages are sent, then won't the externals already be done
with before the stack receives the startup message?


At present they are bound before the startup message - which is the 
problem as there is no opportunity for script to run.


Currently, you can do the suck up and spit out method - you just mustn't 
mark the externals as 'included' in the s/b... And then add code to 
standaloneSaving / standaloneSaved:


standaloneSaving (to augment your stackfile with what is needed)
   create a substack of your mainstack file which contains the externals 
you want in custom props
   a library stack handler in the substack which spits out and sets the 
externals property of itself


standaloneSaved (to reset your stackfile to what it was before)
  delete the substack

Then in the startup handler of your standalone mainstack, 'start using' 
the substack if it is present. That should then load the externals which 
you've spat out to disk in an appropriate place.


Warmest Regards,

Mark.

Re: Widgets as Buttons

[Richmond Mathewson via use-livecode]

At the risk of looking goofy, why not create an SVG image with a solid 
border:

But to get a larger hit area you still have to make a group, because 
SVG widgets don't have margins and they always grow to fill their 
rectangle. It would be nice to be able to define a wide margin.


But if we ever get the ability to use them as button icons, that would 
be an even better solution.

Re:  using widgets for buttons like disclosure triangles.

On mobile they seem very unresponsive.

Jacque says you have to actually tap the pixels inside the defined 
svg area.


We had this discussion before relative to using small graphics as 
buttons. So, are we back to making small groups with a background 
graphic fill white with blendlevel set to 1 or tranparent button on 
top etc.?


In Spotify, they have super small, tiny disclosure, reveal, popup 
thin arrows and they work so well, without your finger having to hit 
some exact target zone… It's almost as if for a small icon that may 
only be 20 X 20 the responsive zone is more like 50X50 with the icon 
in the middle so even "big thumbs" have no trouble.


Any thoughts on best approach? What are you doing?

One wonders if we need an enhancement request (if even possible) to 
set an object prop like:


fullRectResponsive = true

then mousedown/up works whereever you touch inside rect.

or something like that.

Oh hell. Just got home and found this.

Dan and Chipp were responsible for getting the user conferences going.
Dan was outspoken and a gadfly - I never knew him to pull his punches, 
and was a vehement promoter of xtalk. I still have a working draft 7 
copy of the HyperCard Script Language Guide that Dan did for Apple back 
in 1987 sitting by my desk. We kept talking about getting together to 
catch a Giants game but never quite got around to it.
