Re: Cubist's first bug report
What's the culprit for that? I dare say: = It's not the random (as Mark S. proved with his example) = It's not a random-incompatible "add" (see example below) It is the basic problem that LC has with counting items, lines, words or other chunks. The number of is defined in a logically inconsistent way.

Re: Raspberry Pi GPIO
Perhaps the best "library" to Raspi-GPIO, that may also answer most of your technical questions (in the C-part). http://elinux.org/RPi_GPIO_Code_Samples Note the line in the C example that explains how to make this "Raspi 1"-code working on a Raspi 2. Especially for you the WebIOPi may be also interesting: http://webiopi.trouch.com/ Relating to PIR sensors there are well-tested-tutorials in English in the folks (I dont link to the one I used, because it's in German only). === This is my 'unsharp' opinion (may hopefully need an update with LC's FFI): If you use python via shell from LC this doesn't really matter: LC 7 is *much* slower than LC 6, and LC 6 is slower than Python, and Python is *much* slower than C anyway. Sums up to a factor of close to 100 in time needed. LCB will not bring that down below 10, I presume.

Using the GPIO is nothing else than writing zeros or ones to a file. Nobody needs a library for that?

Re: Get url "file:///..."
Hi all,
the task of Jim is, as I understand, that he wants a correct
actual browser interpretation of the file, that is, what Safari
displays, some say HTMLtoTEXT to such a conversion.
LC's status for 'the htmltext' is HTML of before 2005 ...
The applescript is probably instable because of delayed result
sending/ getting but it's the most actual interpretation you can have.
Now I just looked into my treasure chest for MacOS and found the
following. I tested once for 50 files. Worked stable and very fast.
(This is the conversion method that TextEdit uses).
Hermann
-- DOES NOT CONVERT text that is javascript generated by a browser.
-- Convert files on MacOS, tested on 10.11/ 10.12
-- Outputs to an input-file with the ending changed to format
-- "textutil -convert format
-- format is one of the following
-- txt, html or htm, rtf, rtfd, doc, docx, wordml, odt, webarchive
on mouseUp
set defaultfolder to \
"/Users/jimhurley/Library/Mail Downloads/elec_web/precincts/"
put the files into fs
-- filter fs with/without some criterium
repeat for each line f in fs
put shell("textutil -convert txt " & f) into nirwana
end repeat
end mouseUp
If you have all files and only these in one folder you could simply use:
(all files converted by one line, you could do that also in Terminal).

put "/Users/jimhurley/Library/Mail Downloads/elec_web/precincts/" into f0

Re: Getting textShift To Shift Down?
Tested now and it works here:
LC 's textshift does exactly what it *can* do (with the primitive typesetting
system of HTML which it uses):
[1] It takes the baseline, moves the chunk relative to that up or down, leaving
the surrounding text on that baseline.
[2] After that it gives the whole line a new height (if variable textheight) or
fits it midway into the fixed line height, that is it moves the baseline.
One can watch this with with "showlines" and "hGrid".
What you 'optically' want, can you achieve exactly with a professional
typesetting system ("TeX") only or, approximately, if you shift (also) the
*complement* of the object in the line.

TMHO, such threads should end -- if available -- with a full
working solution. Perhaps somebody can use this, for example
me, in half a year :-)
=== HowTo
Switch the "locked" flag (= the check in Finder's "Get info"-dialog
box) of a Mac OSX file.
Yo have to be superuser or the owner of this file for that.
[1] using applescript (see note at end of this post)
on mouseUp
answer file "File to unlock" -- obtain the path/to/file
if it is not empty then
replace slash with colon in it
delete char 1 of it --> delete leading colon <-- BN
do switchLocked(it) as applescript
end if
end mouseUp
function switchLocked ff
return "" & \
"tell application " & "Finder" & \
" set p to alias " & ff & \
" set locked of p to not (locked of p)" & \
"end tell"
end switchLocked
[2] using shell
on mouseUp
answer file "File to unlock" -- obtain the path/to/file
if it is not empty then
put quote into f1
put word 5 of shell ("ls -lO " & f1) into myFlag
--> myFlag is "-" if not locked and "uchg" if locked
if myFlag is "uchg" then
put "nouchg" into myFlag --> lock
else put "uchg" into myFlag --> unlock
put shell ("chflags" && myFlag && f1) into nirwana
-- put shell ("ls -lO " & f1) --> check if it's done
end if
end mouseUp
=== Note
Bernd N. and I had a dialog about the "execution error" of the
original script [1] above and he found the culprit:
If you give an alias that starts with a colon (or a POSIX path
that starts with a slash) then the Applescript Script Editor puts
"startup disk" in front of this and it's OK). We have to delete
the leading colon or put the diskName in front of the path).

Let me add these considerations regarding 'frame delay' by DIY:
== Advantage: We can use the given times or adjust to current
'environment'on the fly if we control the animation by ourselves.
For example change the frame every *full next* 50 millisecs by
send "handler" to me in 50 millisecs - (the millisecs mod 50) millisecs
This holds the animation "in rhythm" and doesn't buffer and spit out
at once the 'waiting frames' -- as some browsers and GIF players do.
== I use to look at (and edit) frames delay with GraphicConverter.
As you say, most gifs (here 99%) use the same delay for all frames,
much too short for usage in HTML5 standalones.
== Regarding frame delays in general, especially usage of gifs in HTML5,
this will be a real ('cross-browser') problem:
"The problem seems to be that many browsers will ignore very short
per-frame delays and ***replace them with a default delay*** (often
0.1 secs). And the cutoff for what counts as a "very short" delay
varies between browsers: Firefox apparently accepts anything down
to 0.02 seconds per frame, while IE ignores delays below 0.06 seconds
per frame."

Re: snapshot and animation capture
[Fits best into that thread, better than creating a new one] Here another community stack, mainly prepared for Raspi, but works (much faster, of course) also on Mac/Win/Linux. The stack is a resizable transparent window-masked stack. = Choose shapes to be created on-the-fly from menu: ... Rectangle, Oval and N-polygons (regular, 3<=N). = Resizing is possible also non-proportional. = Screenshots are done from the shape, i.e. if you use an ... oval you get the inner transparent part from screen and ... the frame of the image is your oval. Simple rectangle shots are fast (impressing LC-features). Shaped shots need much more time, incl. creating and saving image, on a medium fast machine (Mac mini, 2.5 GHz) 800 ms and 1800 ms on a Raspi2. (Of course this is dependent of image size, the times are averaged over sizes, the average size is 600x400 px.) For the "shaped-shot" part I'm probably too complicated and don't see the easy way.

Re: HTML5 "Features" Library Substacks and "send ### in time"
Ciao, [1] Firefox does NOT work any more since version 44.0 with LC's HTML5-standalones. Sadly, because Firefox was up to 5 times faster with the standalones (with loading AND playing) than other browsers. ALL standalones are affected, no matter the dp version. This is reported at Bugzilla@Mozilla, they really try to help us. If I read that correct, it is even planned for Firefox 47.0 to implement some backward-compatibilty. Peter B. will 'repair' that from LC's side soon (8.0.0-dp15), you then simply have to recompile your projects with the new version. [2] LC 8.0.0-dp14 has with my tests a speed loss by factor of up to 10 compared to dp9. [Will report in detail to QC tomorrow]. Hope your results are better. Please tell us. [3] In general to HTML5: PeterB. and the dev team is really working hard on all the nasty detailed problems (you can see that immediately when reading at github.com/livecode/livecode) with the HTML5-standalone builder. ==> There is an own HTML5-Subforum <=== http://forums.livecode.com/viewforum.php?f=120 Peter B. comes in regularly there and gave already a lot of valuable information, nothing is unanswered until now.

Re: snapshot and animation capture
Hi, I've made a stack for the Raspi collection, that does the following: Creates a *resizable* rectangle frame (window shape of a non-opaque rectangle), currently set as systemWindow. You can drag that around the screen and trigger a small button on the frame. Then a screenshot of the visible interior of the frame is made and saved as PNG. You can open and view these 'shots' in the stack, if it is switched to non-window-shaped. It's all "intermediate" Livecode, runs on Mac/Win/Linux and is fast enough on a Raspi. On Win/Linux resizing "flickers", you may play there with the 'update-beat' (currently 4 ticks), but it works. I didn't publish it until now, because "window-shaping" is currently/not yet possible in the available Raspi IDE's or standalones.

What numbers do you wish to see there? Possibly you are thinking of a scrollbar that varies it's thumbs units. Say for example, if the width of your scrollbar is 200: from left to left+40 divides into -5*60 to -2*60 = 180 units scaled to width 40 from left+40 to left+160 divides into -2*60 to 2*60 = 240 units scaled to width 120 from left+160 to left+200=right divides into 2*60 to 5*60 = 180 units scaled to width 40 This would scale the **INPUT** (=the x-axis), what is possible to achieve, but you then have to script your own "showValue" field. The current approaches of Kay and me scale the **OUTPUT** (= y-axis), usually quite different. @Kay C.

Look positive at HTML5 now
Here a constructive post to HTML5. CLUSTER-6: ** Six HTML5 standalones running smoothly together in one window. ** hh.on-rev.com/html5/ (the cyan button "CLUSTER" is at bottom). I don't hesitate at all to criticize if appropriate, but much the same I don't hesitate to praise: Have fun and try yourself, LC 8.0.0-dp15 did a big step forward with the HTML5 builder! Look at your great work, Peter (and some co-workers)! After you started the six modules you can have with that cluster 9 clocks running "in sync". Work with one module and watch the others. Load one single other module before loading cluster-6, then it's faster. This is a real stress test for browsers, compare their performance with cluster-6. Currently Firefox is running fastest (with animations), Safari has the best caching for repeated usage. Zoom the window *content* in/out to fit your window or screen (I mean the cmd-minus/plus/0 mechanism). I have (with a 50 Mbit connection) Cluster-6 complete here in ... 12 seconds with Firefox ... 16 seconds with Safari ... 32 seconds with Chrome ... 40 seconds with Opera This is my opinion to the current state of HTML5: It's still in the lower half of a first final state. **And it's not very coincident with my wish list.** But where it is, it is far beyond my expectations. And it has already now become hard to touch it's limits (I tried). I like it, go on! === Hermann p.s. these modules demo a little bit what already works fine.

Mark Wadd. said recently, freely out of my brain: 'LC uses emscripten only to render into the canvas'. I suggested the use of other HTML5 objects already in November and got a strict "NO": The HTML5 standalone will not have features that are not in the engine. The other way is already somehow possible: One can have a webpage with actions that work on the LC canvas like on every other canvas, for example get mouseActions or keyboardActions if over the canvas. But for that the LC canvas is a "dead" drawn object, like a still image, you can't go 'deeper'. Except LC would allow to attach js handlers alike the browser objects do.

Re: LiveCode for the Hobbyists
Really good points, Roland. Let me add explicitly this one. Build on the next generation, who will become decision maker in a few years. And, if they *know* the software, may also become possible buyers of LC-related products: Give teachers and their students in class FREE copies. Give university students and hobbyists very cheap copies. If the company continues to have such crazy pricing strategies as now then it will loose in sum: The negative income by people "jumping off" will be greater than the additional positive income by raised prices. For example I went with backing nearly everything in the last three years already over my limits: An Indy license, a community membership (who of the writers here has also one?), an additional HTML5 license, a lot of time wasted for beta-testing. I'm hobbyist, sell nothing ... The next "pricing game" will force me to jump off. And jumping off will mean to jump off by 100%, in anger, not only partially. And certainly I'm not the only one who works for no money, pays only to support LC.

Hi, I read about "do" again last night, because Craig N. (in a comment to Peter H.'s QCC #16941) suggested to use single quotes also for triggering a re-compilation, as "do" does. He used a 'declaration'-example similar to yours. Now you end in a rather nifty example. on mouseUp repeat with x=1 to 20 do "local tVar_" & x do "put x*x into tVar_" & x end repeat put tVar_5 into fld 2 end mouseUp [1] In strict compilation mode it throws "unquoted literal" on "tVar_5", all OK. [2] In slack compilation mode it throws "local tVar_5", also OK? I think so. The point is: *** "do" recompiles ***. Thus line 3 with x=5, what is "local tVar_5", is offending in that re-compilation, because tVar_5 is already implicitly declared in line 6 of first compilation. > ..

Re: Programmatically determine the average greyscale
BR and jacques, it's kind of a 'LC-mania' of me to put a fully working solution, if available, near the end of a thread. Here's one I made for converting to grayLevel colours and adapted to your case. Tell us your solution also, please. The following is pretty fast, I wrote it after learning some secrets of imageData from Bernd's "little stacks" and forum posts. So praise him and LC's pointer arithmetic for the speed. It takes here on a medium fast machine in average 16 ms for your 20x20 px image segment (incl. setting of the button's or field's adjusted textcolor) === local ii="preview", bb= "bigBen" -- image's and button's name ## Function computes an average RGB-colour value for an image ## (or a rectangular segment of it). ## Divide below in each loop if image is *very* large -- x = imageData 32bit ARGB of the full img ii -- w = width of the full image ii -- pixel rows = r1 to r1, pixel cols = c1 to c2 -- wr, wg, wb = weights for r, g, b function weightedColorMean x,w,r1,r2,c1,c2,wr,wg,wb repeat with j=r1 to r2 put (j-1)*w into j0 repeat with i=c1 to c2 add sum( \ wr*byteToNum(byte 4*(j0+i)-2 of x), \ wg*byteToNum(byte 4*(j0+i)-1 of x), \ wb*byteToNum(byte 4*(j0+i) of x) ) to s end repeat end repeat return s div (sum(wr,wg,wb)*(r2-r1+1)*(c2-c1+1)) end weightedColorMean on mouseUp put the millisecs into m1 put the width of img ii into w put the imageData of img ii into iData -- perception values: put weightedColorMean(iData,w,20,40,20,40,1,6,3) into M -- usual luminance formula (wikipedia, cited by Jaques) -- put weightedColorMean(iData,w,20,40,20,40,3,10,1) into M if M > 191 then set textcolor of btn bb to "51,51,51" else set textcolor of btn bb to "255,255,225" put M && the millisecs-m1 && "ms" into fld 1 end mouseUp === Hermann p.s.

Re: Programmatically determine the average greyscale
BR, you do estimate the luminance of a 120x175 = 21000 px region on base of the evaluation of ONE single deterministic pixel? Accepted, of course, but then it may be better, from a probabilistic point of view, not to take "the" pixel (40,40) but *any* randomly chosen pixel of that region. You could do for that: set randomseed to (char -8 to -1 of the millisecs) put 19+random(120) into pX ; put 19+random(175) into pY == hh p.s.

[2] You CAN solve this in a very short time with LiveCode. You could give the following a try (less than 5 minutes). This is ONE 'static' setting, that works for ALL images. Make a new textField, that will use contrast to *every* single pixel that is below the text. It requires later on only to script that the name of the buttons will be hidden and instead displayed by the correspondingly placed and sized field (you can use with that even formattedHeight and formattedWidth to optimize sizing and location). Settings: opaque=false locktext=true autohilite=false forecolor=255,255,255 script="on mouseDown;grab me;end mouseDown" ink=notSrcOrReverse showBorder=true -- needed with that ink or if you wish a border borderWidth=0 -- needed with that ink, not if you wish a border blending=12 Increase the blendlevel to have less contrast between "black" (darkGrey) and "white" (lightGray) blendLevel=0 gives 'full' black and white Now bring this field to front and drag it over any part of pictures or black/gray/white rectangles of your stack. You should have readable contrast while dragging and whereever you drag it (if the field is not empty).

Re: How do I enable scrolling of a group ?
This is essentially the same technique that Scott R. suggested. New is the MOVE-TO-SCROLL-FACTOR, in case you prefer that. ** The scroll respects here the group's relative to card's size. ** ** Thus scrolling becomes "parallel" to the mouseMove distances. ** For example if you move your fingers/the mouse from (20,70) to (50,30) then the hscroll of the the group changes by +30 and the vscroll of the the group changes by -40. Of course you may moreover scale these factors (fw0, fh0 below) to your needs, for example to an increase for a large display. -- In group's script. -- Here given for hscroll and vscroll, mostly I use only one of both. -- Also I give it for mouseMove, you change this to your need -- (touchMove ...) better than I do. local d0=false, x0=0, y0=0, h0=0, w0=0, fh0=1, fw0=1 on mouseEnter; put false into d0; end mouseEnter on mouseUp; put false into d0; end mouseUp on mouseRelease; put false into d0; end mouseRelease on mouseMove x,y if not d0 then exit mouseMove set hscroll of me to w0+fw0*(x-x0) set vscroll of me to h0+fh0*(y-y0) end mouseMove on mouseDown put (the height of this card) div (the height of me) into fh0 put (the width of this card) div (the width of me) into fw0 put true into d0; put the clickV into y0; put the clickH into x0 put the vscroll of me into h0 ; put the hscroll of me into w0 end mouseDown I also have sometimes, in order to have a 'static' scrollbar size, a transparent (for example by using ink 'noop") object, may also be disabled, of card's (half) size in the group. ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode

He uses images as backpattern. For text the label. How to manage that with a transparent button and dropshadow?

Re: How do I enable scrolling of a group ?
Alex, sorry, I know from your posts which I read long before writing to this list that you don't need help for the scrolling per se. I just wanted to add my MOVE-TO-SCROLL-FACTOR as a whole. inside of a working script. I don't like to scroll with 5 long moves until the targeted loc is reached and may be I'll use your app. :-) The point with the scrolling is probably given in the dictionary entry to "scrollbarDrag": "Sent to a field, scrollbar, or group when the user drags the scrollbar thumb **or when a text selection causes a field to scroll**" The "or-part" may be the explanation why scrolling works with the text field and not with the group. Without 'autohilite' a textfield may also not scroll. "Doing Touch scroll by rawkeyDown" will be interesting for a lot of readers. Would be great if you share your solution with a script snippet at the end of this thread ...

Thanks again Graham One remark to the internet date (which is the date format I always use and then convert to dateItems if needed for calculations). If using recent or future dates one should have in mind that "the internet date" respects **daylight saving offsets** of the dates.

Re: Problems creating a field in LC8 DP16
William, meanwhile I tested this in depth and must say that you are right with that: The formattedWidth and formattedHeight don't show the exact boundaries, as you wish. But from my knowledge of TeX I know, that this isn't obtainable for fonts that don't have an extremely optimized metric. This isn't even solvable by "pure" typesetting engines (nor by LC). The formattedWidth is meanwhile pretty good measured. [It has some problems with extreme slanted fonts. That's the problem of non-perfect text-metric of the fonts.] The formattedHeight is *better than ever*, but has still some problems with interline-spacing at top or at end of strings. So, with the final version of script you probably have to wait for stable 8.0.0 (or 8.0.1) -- there is too much "in motion" with the new "text engine". Peter certainly could say more here. Perhaps you should report this as bug, so that they know there are, despite their improvements, still problems? We should use for demos of these problems, to be fair with respect to font-metrics, a high-quality otf/ttf-font (for example "Skia"). Hermann p.s. I was some time ago preparing a stack for the Raspi-stacks collection that shows the exact boundary box of the "outer opaque region" of a transparent object. I'll expand it now to test also the formattedHeight and formattedWidth of a text-display. Wprothero wrote > Is this a bug? Shouldn’t the formattedHeight and formattedWidth show the > text?
