Re: What do you want to contribute?
I would be working to extend the natural language syntax in every way possible through the new language capabilities. For twenty years now, whenever someone says LC is verbose, we've responded with sort lines of fld demo by item 3 of each put word 3 of line 2 of x into line 14 of y or something similar. Chunk syntax is awesome, but it's not the end. The underlying principle is that whatever you can reasonably interpret from an intuitive english expression will be more powerful than other syntaxes. Some examples off the top of my head, english similarity level TBD: swap the values of x and y apply function trim to each line of x apply function demo to x until the result stops changing scan all the files in directory demoDirectory including subdirectories and put the paths of the ones that contain the letter z into x And finally, let's go crazy: open a window if full screen mode color it black place 20 white pixels randomly on the screen, with no pixels closer to each other than 15 pixels create a new graphic of type player use the image player.png for the player graphic this is where the game starts if the user tilts the device left or right, accelerate the player graphic uniformly in the direction of the tilt, proportionate to the amount of tilt, so that at maximum tilt it takes 120 ticks for the player graphic to move across the whole window If the user touches the screen, accelerate the player graphic uniformly toward the user's touch if the player graphic reaches the same horizontal location as the user's finger, decelerate the player graphic uniformly to motionless in 10 ticks once every 30 to 240 ticks, create a new graphic of type star place the new star graphic randomly, but always 50 pixels from the top of the window use the image star.png for the new star graphic accelerate the new star graphic uniformly toward the bottom of the screen so that it takes 120 to 300 ticks to get to the bottom of the screen if the new star graphic reaches the bottom of the screen, delete it if the new star graphic collides with the player graphic, delete the new star graphic and add 50 points to the player's score sixty seconds after the player graphic is created, stop all motion, delete all the star graphics if the user touches the player graphic, set the player's score to 0 and start the game I know that's crazy. gc On Wed, Feb 13, 2013 at 5:29 PM, Peter M.

Re: What do you want to contribute?
Here's an interesting real(ish) world example:
http://www.leancrew.com/all-this/2011/12/more-shell-less-egg/
The goal is to find the ten most common words in a text file.
Donald Knuth wrote something in literate code form, in Pascal. The result
was ten pages of code. In the article, Doug McIlroy wrote it in shell
script as:
1 tr -cs A-Za-z '\n' |2 tr A-Z a-z |3 sort |4 uniq -c |5 sort -rn
|6 sed ${1}q
and called out Knuth on his supposedly more clear, ten-page solution.
It turns out six lines of transcript accomplishes the same thing:
repeat for each word w in replacetext(url (file:
filePath),(?i)[^a-z], )
add 1 to c[w]
end repeat
combine c using cr and comma
sort lines of c descending numeric by item 2 of each
put line 1 to 10 of c
If anyone can do it more elegantly, I'm curious to know how. But in a
language where we can write our own syntax, this seems likely to be
possible:
put file filePath with all non-alphabetic characters replaced with space
into fileString
for each unique word w in fileString, put w,the count of w cr after
countList
put the first 10 lines of countList sorted numeric descending by item 2
Maybe that's not clearer, but it should be possible.

Re: What do you want to contribute?
yeah, I wasn't happy with that syntax as I was typing it. Part of the
beauty of being able to create/share syntax is that others can improve on
what you come up with, and only the good syntax survives into general
usage. Maybe this would be better:
put file filePath with all non-alphabetic characters replaced with space
into fileString
for each unique word w in fileString
put w,the count of w cr after countList
end for
put the first 10 lines of countList sorted numeric descending by item 2
or maybe this:
put file filePath with all non-alphabetic characters replaced with space
into fileString
put ((each unique word w),(the count of w)cr) in fileString into
countList
put the first 10 lines of countList sorted numeric descending by item 2
or heck, maybe this -- I rather like the use of individual to represent
the non-alphabetic replacement in the earlier examples:
put the 10 commonest individual words in file filepath along with comma
the count of each cr
but again, only actual experimentation with real developers will determine
what makes intuitive sense and what is just useless too-specific jargon.

Re: What do you want to contribute?
w is a string, but I'm assuming that in context, syntax like count of would make sense syntactically, and that the language could make it work. yeah, commonest sucks, but I didn't want to push it by going with two words like most common. Also, given how specific the use case is, it would likely not work as syntax. for each seems like a reasonable synonym for repeat for each, Your example seems like a reasonable alternative. My goal wasn't to define the one true syntax for this example, but just to throw out some alternatives to suggest what I think should be possible. In practice, whatever makes sense to enough people will be the syntax that survives.

What's the best way to store data that one iOS app sends to another?
Each instance of my iOS app needs to maintain a list of other users of the app and be able to send them information, and retrieve information they have sent. Think email, but without the image, attachment, etc. overhead -- more like sending tweets as emails. What sort of host/infrastructure would work for this?

Re: What's the best way to store data that one iOS app sends to another?
I've been thinking about this. I'm assuming (all with salt): 1. At some point the user set a password. At that point the iOS app applies MD-5, sends that to the server, and stores the hash locally. 2. When the app wants to access something from the server, it makes a request for an authentication string. The server takes the user name and the current time and sends that back,and stores that hash itself. The iOS app hashes the authentication string combined with the password hash, and includes that with its requests. Since both the server and the iOS app know the authentication string from (1), they do not have to exchange it now. Richard, is this something like what you're doing?

I've successfully signed up for stackmob and connected with it.
Interestingly, it ended up being simpler than I expected. I spent several
hours trying to find the right url encoding etc., but it turned out this
worked:
on mouseUp
set the HTTPHeaders to fld headers
post fld data to url (fld url)
put it into fld result
end mouseUp
Where fld headers looks like this:
//version sets your REST API Version. 0 for Development. 1 and up for
Production
Accept: application/vnd.stackmob+json; version=0
X-StackMob-API-Key: my-key-here
Content-Type: application/json
and fld url looks like this:
http://api.stackmob.com/chatmessage
and fld data looks like this:
{user:t...@mailinator.com,forecast:7,t:vlIj,zip:63108}
{user:o...@mailinator.com,
forecast:7,t:vlIj,zip:63108}
no special encoding, no https.

Re: [Topic][Dumbfounded] Is there a way to resize and move a group without touching the inside objects
Hi Scott, I tried to simplify this and make it so that each control is adjusted in one step. This also optionally take different scaling factors for horizontal and vertical. Let me know if I missed anything. I'm not sure what everyone was seeing with resizing the group affecting the objects in it -- I'm not seeing that as far as I can tell. All the implementations shown so far are losing fidelity due to rounding. If anyone is going to repeatedly resize groups/objects like this, it would make sense to store the original rects as a separate property, and always start from there. If the resizing needs to be cumulative, then I'd store the cumulative resizing factor as a property of the group, then when resizing multiply that by the new/additional factor before applying that to the stored rects to set the sizes. Once we have open language, I'm so looking forward to being able to say something like: set the rect of every control of G to integerRect(shiftRect(scaleRect(shiftRect((the rect of it),-L,-T),H,V),L,T)) gc command scaleGroup G,H,V if V is empty then put H into V put the left of G into L put the top of G into T put shiftRect(scaleRect(shiftRect((the rect of G),-L,-T),H,V),L,T) into R repeat with N = 1 to number of controls of G set the rect of control N of G to integerRect(shiftRect(scaleRect(shiftRect((the rect of control N of G),-L,-T),H,V),L,T)) end repeat set the margins of G to scaleRect((the margins of G),H,V) set the rect of G to R end scaleGroup function scaleRect R,H,V if V is empty then put H into V return (H * item 1 of R),(V * item 2 of R),(H * item 3 of R),(V * item 4 of R) end scaleRect function shiftRect R,H,V if V is empty then put H into V return (H + item 1 of R),(V + item 2 of R),(H + item 3 of R),(V + item 4 of R) end shiftRect function integerRect R return round(item 1 of R),round(item 2 of R),round(item 3 of R),round(item 4 of R) end integerRect On Fri, May 10, 2013 at 7:00 AM, Thomas McGrath III mcgra...@mac.comwrote: Monte, I won't be attending this year but I will be on the simulcast so I'll sort of be there in spirit at the conference…..

Re: scrolling stack I made
Hi Colin, Nice work! I added timing code to get the framerate. On my macbook pro when nothing is actually moving, it achieves about 40 fps. When the images are moving it drops to about 24 fps. I'd be curious how using the move command might compare. I don't think it would be faster since with each frame it's likely that all the commands would have to be canceled and re-issued to change the speed. I also simplified the movement routine to a single line to update the position of each object, which eliminated the need to store the position in the array.

Re: randomly order a list
There is, indeed much confusion here. I, of course, am correct ;-) I simplified the problem to a list of two items: 1,2 That way the sort command has exactly two outcomes. It either reverses the list, or it doesn't. The two outcomes should happen roughly 50% of the time. This script demonstrates that sorting by a large random number works, and sorting by a random number up to the number of items (2) does not. on mouseUp put 1,2 into originalList repeat 1 put originalList into newList sort items of newList by random(2) if newList is originalList then add 1 to sameCount1 end repeat repeat 1 put originalList into newList sort items of newList by random(9) if newList is originalList then add 1 to sameCount2 end repeat put Sorting by random(2) kept the same order sameCount1 out of 1 times. cr \ Sorting by random(9) kept the same order sameCount2 out of 1 times. end mouseUp For anyone interested in the math, as you would expect, the random numbers for the sort come out 2,1 roughly 1/4 of the time, so the result is that the list is in the same order roughly 75% of the time when using random(2). Here's one result I got: Sorting by random(2) kept the same order 7514 out of 1 times. Sorting by random(9) kept the same order 5014 out of 1 times.

Re: randomly order a list
Dar -- I hardly think you need my blessing, but I agree with your definition of p(k). I ran some numbers through Wolfram Alpha, and it looks like even for 100 item lists the probability of the first item being sorted to the first spot is about 0.015, or 1.5 times what it should be if sorted by random(the number of items). Of course, that's not the overall probability that the list is mal-sorted. That probability is much higher, and I'm not sure how to calculate it (hanging my head in shame), but roughly: Say you have a set of 100 items where each gets a unique random number to sort by except for the first two, which both get 1. They *should* be able to come out either A,B or B,A, but they can only come out A,B. Note that this does not depend on what common number they get -- even if they both got 100, then although both of them would be moved to a different spot in the output, there should be two possible outcomes, but there is only one. Hence the probability under this circumstance of having an improper shuffle is 0.5. Likewise, if three items had the same random number, there would be only one possible outcome when there should be 3*2*1 = 6 possible outcomes, so there is a 5/6 or roughly 0.83 probability of a bad shuffle. This goes up, obviously, as the number of dupes increases. Further, there can be more than one duplicated number. If two items have 99, and three others have 23, then the probability of an improper shuffle is 1 - 1/2 * 1/6 = 1 - 1/12 = about 0.92. My failure comes in aggregating all the various possible sets of duplicates. Of course, the goal is achieving success, not calculating failure. I did the math (okay, Wolfram Alpha did the math) and using: sort lines of myList by random(9) random(9) For a list 1 million lines long has a probability less than 1 in a million of having even a *slightly* non-random order (within the bounds of the random number generator). That seems good enough for me. For shorter lists the concatenation would be unnecessary. I commented on the feature request. I think this would be an excellent application of the new language features once they are available. gc ___ 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

Re: randomly order a list
At the risk of beating the decaying equus -- the previously suggested random() solutions should be fine for all purposes --I found an alternative that: 1. Is faster than sorting by random(9) random(9) 2. Is about as fast as sorting by random(9) 3. Is (I think) less likely to have duplicate sort keys The drawback is that it is determinative (albeit random) for any given set of data, unless you are willing to accept performance equivalent to sorting by random(9) random(9), while providing near-certainty of a true sort (I think). The one-time, as fast as any solution so far, sort is: sort lines of myVar by md5digest(each) Collisions are highly unlikely in 128 bits. Even random(9) random(9) only provides about 60 bits, which, to be clear, is *more* than enough, but md5 is (I think) even more certain, and faster.

Re: randomly order a list
What code were you using Alex? I thought the first step(s) of the MD5 process reduce (or grow) whatever input string is given to 128 bits, and then everything from there operates on the 128 bit data. Likewise for SHA1, in 160 bits. In other words, the size of the individual strings should have a limited impact on the MD5 algorithm. For example, the two times returned by this are nearly identical: on mouseUp repeat 5 put random(9) after S[1] end repeat repeat 5000 put random(9) after S[2] end repeat repeat with i = 1 to 2 put ticks() into T repeat 100 get MD5digest(S[1]) end repeat put i ticks() - T cr after R end repeat put R end mouseUp On Tue, Jun 4, 2013 at 6:26 PM, Alex Tweedly a...@tweedly.net wrote: No comments on the collision-or-not-ness, but some concerns about performance. The performance of random() random() is conveniently data-independent, but that for md5digest() is not.

I didn't test it thoroughly, but the swap-over point is fairly low - somewhere around 500 chars per line. -- Alex.

I did some reading and it sounds like md5 and sha1 should both be deprecated in favor of sha256. On Fri, Jun 7, 2013 at 10:57 AM, Dar Scott d...@swcp.com wrote: Right. There is a little bit of overhead for padding for both md5 and sha1 (they use the same padding method), as a string a multiple of 64-bytes is created. Then each resulting 64-byte block is processed; this is linear. The methods are very similar, an important difference being the number of 32-bit chaining variables; md5 has four and sha1 has five. (The final values are the hash.) That is a factor in making the sha1 basic operation take longer, and thus the whole process take longer. (We could look it up and count all the XOR, SHIFT, OR and AND operations, but you can imagine there would be more in scrambling five things instead of four--well, scrambled along with a portion of the block.)

Re: Really large groups
I agree that it seems challenging, but I think if it's done right it could be fairly transparent and robust. I wrote some code to display the number of factors of each number from 1..N. It uses a graphic and draws a single-pixel-width vertical bar for each number. It creates a new graphic for each hundred numbers (they start to become unwieldy when you try to set more than a thousand points or so). All of that works, but if I'm trying to do 1..50,000, or even 1.. a few million. That makes the group with the set of graphics I'm creating up to millions of pixels wide. Insane, I know, but the recent progress on the twin prime conjecture has me excited and curious.

Re: Weekend challenge
I'd be very curious to know what the rails code looked like. I've said many
times, and I hope the new language features enable this soon, that there are
*many* extensions to the LC language that would be equal parts intuitive and
useful.
The unique requirement on the type might be (assuming the data has been
processed to 6-item comma-delimited lines):
put the indexes of lines of myList where the count of item 4 of each 1 into
myDupedTypes
For the requirement across the ID, section, and subsection, and type, not
counting the type when it dupes its parent subsection, maybe:
put the indexes of lines of myList where item 1 of each is among the items of
item 2 to 4 of any into myDupedIDs
Just a thought.
As one example of what we're missing, consider this implementation of Conway's
game of Life in J:
life=: (_3 _3 (+/ e. 3+0,4{)@,;._3 ])@(0,0,~0,.0,.~])
Granted, that looks like greek, but J is incredibly expressive. Consider what
it does in just one line:
1. Pad the array representing the current state of the grid with zeroes all the
way around, so
1,0
1,1
becomes
0,0,0,0
0,1,0,0
0,1,1,0
0,0,0,0
2. Slice that array up into 3x3 sub-arrays, allowing overlaps, so now we have:
0,0,0 0,0,0
0,1,0 1,0,0
0,1,1 1,1,0
0,1,0 1,0,0
0,1,1 1,1,0
0,0,0 0,0,0
3. Sum those arrays to an element in a new array -- 1 if the sum is 3 (dead
cell with 3 live neighbors, or live cell with 2 live neighbors) or 4 if the
center cell is 1 (live cell with 3 live neighbors). The result is:
1,1
1,1

Thanks Geoff, I'll definitely look it over. I actually won't have to use it
though because I was excused from the exercise, the server is doing it
instead. But it bugged me that I couldn't write a nice, neat handler to do it.
The backstory: The client wanted a data verification check performed on both
the server and in the LiveCode stacks. I spent a weekend toiling over this, I
probably wrote six or eight different versions using different methods. I
never did produce anything neat and compact, so the next Monday I asked the
server person how they did it. They replied with a four or five line
algorithm which was very close to one of my initial attempts, but they didn't
have to do any duplicate checking. Apparently there's a way in Rails to do
that easily. They were bouncing arrays around. A couple of my attempts used
arrays but looping through all the sub-keys wasn't any easier than just
looping through the list.
I was feeling kind of miffed that they were able to produce a workable script
in a couple of hours and I'd been messing with it for days. Fortunately the
client said never mind, they would just use the one on the server, and that I
should move on to other things.
I was not disappointed, but it did leave me feeling kind of stupid (and a
little defensive about LiveCode.) I was relieved that no one here jumped in
to say oh, just do this. But I still wonder if I was missing some cool
trick.

Re: RosettaCode
I don't have much experience with the site, but what I've seen seems more
friendly than contentious. The goal seems to be the exchange of information, to
help people learn about the different languages.
With the new language features coming in LiveCode, I think it provides a rich
template for extensions to our syntax. For example, the anagrams problem made
it abundantly clear that we need a sort characters command, as well as words.

Re: Vertically aligning text in a field
Not sure what's up with the offset that seems constant and inherent, but this corrects for it. It does nothing about the apparent offset caused by the difference between the textheight and and textsize of the first line, because if the size varies, the textsize returns mixed. In any case, this works for me to a reasonable degree of accuracy: set the topmargin of fld 1 to (8 + the height of fld 1 - the formattedheight of line 1 to -1 of fld 1) div 2 Here's a demo stack that shows what this does. Each time you click the Test button the text changes, then vertically aligns, then puts in two equal-height boxes above and below to show the results. https://dl.dropboxusercontent.com/u/41182876/vertical%20text%20demo.livecode On Sat, Dec 20, 2014 at 11:24 AM, J.

Re: Inspector Issue
Sorry I didn't see this before -- if you're seeing that the problem is now fixed, then maybe -- maybe -- there was something wrong with the stack before. If you still see the problem, if you have a large number of cards/controls, maybe there's some inherent limit in the inspector you're hitting. Navigator has limits as well, they're just very large. I think in menus it's something like 300 cards/objects, and in lists I think it's 3000, or maybe 10,000. Those were set a long time ago because of performance limitations. At this point I could probably remove them and the engine/Navigator would likely hold up for much larger counts.

Re: A Got-Ya
Two things to consider: 1. It's almost impossible to catch conflicts with custom properties. They don't have to be mentioned by name in a script because: 2. It's a feature that custom property names can be stored/referenced using variables. For example: repeat for each item P in left,top -- not custom properties, but the same principle applies set the P of button example to 10 * trunc(the P of button example / 10) end repeat If you have a large number of custom properties to initialize, this allows you to do something like: put cProp1,23 cProp2,18 cProp3,98 into P split P using space and comma repeat for each key K in P set the K of button example to P[K] end repeat In neither of these cases would it be easily detectible to the compiler what (custom) properties are being referenced, and these cases aren't close to pathological. On the other hand, simply disallowing the use of a variable to store/reference a (custom) property would be a significant loss of functionality.

Re: A code style question
I figured the first version would be faster, since it only checks each thing once, where the second version tests some booleans twice, but this isn't going to be called repeatedly, so maximum performance isn't an issue. I was more curious about the readability, because I thought I might be the odd one out here, and it seems I am. The nested if statements in the first one, and the duplicated set the baseID of this stack to this card offend my eye. Once I realized I needed to test for exists OR is among more than once I used a separate function for those. Along with an inline if function I already had, and switching from a stack property to a local, I came up with: local baseID function baseID newID put iff(validID(newID),newID, \ iff(validID(baseID), baseID,this card)) into baseID return baseID end baseID3 function iff X,T,F if X then return T else return F end iff function validID I return ((I is among the items of this card,card list,background list,stack list) or exists(I)) end validID Maybe not everyone's cup of tea, but clear to me.

Bernd's solution is correct if you really want to create/delete cards. It would be better/more scalable to just maintain a list of the information and use a single card to display it. Then deleting a card would just mean removing an entry from that list. ___ 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

Refactoring
Small thing, but I just turned this twelve-year-old code: put Double-Click: into tProperty if the optionKey is down then if the commandKey is down then put Option-Command-Double-Click: into tProperty else put Option-Double-Click: into tProperty end if else if the commandKey is down then put Command-Double-Click: into tProperty end if into this: put Double-Click: into tProperty if the commandKey is down then put Command- before tProperty if the optionKey is down then put Option- before tProperty I love turning ten lines of code into three lines of code. I hope twelve years from now I can look back at those three lines with the same degree of horror I feel now looking at the ten-line implementation. ___ 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
Re: stackfileversion and locking 6.5.2
well that didn't take long :-P It turns out that there is one field in the stack -- delete the contents of that field, and the stack opens fine in 6.5.2. I copied the contents of the field and pasted into Pages, then deleted the contents of the field, and the file opened fine in 6.5.2. I then pasted the contents back in, and the stack survived.

(this way, any references in the stack that use the stackname won't be broken). When this is done, when you save it, rather than just saving it brings up the filename dialog as if it were a new stack, and if you try to save it in the same place with the same name, you receive the usual warning about overwriting the stack.
