Re: Filter with wildcards

[David V Glasgow via use-livecode]

This is the thing about regex, amazing,powerful, impressive, but scary as hell.

I will play with this a little, though… so thanks for your time when you should 
have been doing something else.  I appreciate it.

Re: Weird window behavior

[David V Glasgow via use-livecode]

Only just catching up with this (been walking in Scotland)…

Probably not tremendously informative now, but I’m not using Levure, I am using 
backdrop, and on Ventura.

I’ll check the state of RaiseWindows when I can - would it be expected to 
change depending on backdrop use?

 Do you (or anyone else who has chimed in on this list) have the backdrop 
 feature enabled?
 
 The reason I ask is that the behavior you describe is similar to this 
 report https://quality.livecode.com/show_bug.cgi?id=24199 (I think at 
 least) - which has now reduced to being due to the backdrop - 
 https://quality.livecode.com/show_bug.cgi?id=24200.
 
 Warmest Regards,
 
 Mark.

Creating 'read only' text files

[David V Glasgow via use-livecode]

Hi folks,

Really simple question that I can’t see having been asked before, so here goes…

I have a stack that outputs small text files.  Each includes a hash value 
referencing part of itself that can be checked subsequently, so any change to 
the text can be flagged.  

Is there a way I can easily create read-only files (Mac & Win) to discourage 
accidental user changes?  No need for encryption or hiding information 
anywhere, I just want to deter casual oopsies.

Thanks in anticipation...

Re: Weird window behavior

[David V Glasgow via use-livecode]

Me too.  Or maybe me too.  Is this the same thing?...

Even if focus shifts from my stack to Message Box, the next click on my stack 
causes it to just disappear.  Most alarming until I realised what was 
happening.  My stack is just behind everything else and CMD tab (x2) brings it 
to front.  Phew...

M2, LC 9.6.8

Sort list alphabetically- ignoring first character if it is a space

[David V Glasgow via use-livecode]

I am trying to alphabetically sort a list of unique strings, some of which have 
a leading space character.  I need these to sort as if the second character is 
the first character rather than all space prefixed strings being bunched 
together.

I just had a hilarious conversation with ChatGPT on this challenge  We ended up 
having a disagreement about whether a keyword “ignoring” exists in Livecode.  
Please tell me it doesn’t.  (although even if it does, I don’t think it helps 
me with my task)

Anyway, I did learn something, but not whether there is an elegant way to do 
this.

I can see how I could extract strings starting with a space, replace the first 
character with the second character, combine the lists, sort, then replace the 
doctored strings with the space prefixed originals.  

However, I couldn’t help but wonder if there is a better  solution.

Anyone?

Best wishes,

David G

Getting OS user name

[David V Glasgow via use-livecode]

Hi folks

Three questions…

1/ On Mac & Win, are there any circumstances in which (assuming itemdel=“/“) 
the last item of specialfolderpath(“home”) is not the current user’s name? 

2/ Is this always the same as doing a “whoami”?

3/ Any LC method of getting the long user name?

Of course that is completely true for academic content!  This ain’t that.

In the paper I simply state that all text searching, manipulation and 
aggregation was achieved using Livecode scripts, with a footnote to a brief 
description and link to … 

Go on.  Ask your wife.  That is how it’s done. (unless you used R, or Python, 
which are celebrities needing no explanation or external link)

The https://livecode.com landing page is rather sparse, and focussed on drawing 
customers in rather than conveying anything about text processing, or obvious 
links to information on text processing.  No criticism of that at all.  It’s a 
commercial site.

Referencing Livecode

[David V Glasgow via use-livecode]

Hi Folks,

I am writing a paper for publication (I hope) describing analysis of internet 
predator messages achieved using Livecode.

I want to reference LC but I am not sure if there is a standard form or URL for 
doing this.  If not I am inclined to use https://en.wikipedia.org/wiki/LiveCode 

Any alternative suggestions?

David Glasgow

PS Also, while trying to find a suitable URL I came across the ‘Cheat Sheets’ 
page and PDFs, and stumbled on a couple of errors in the just LC one… not sure 
who to alert.

// String

"foo" & "bar" is "foobar" "foo" && "bar" is "foo bar" "str" begins with "st"
"str" ends with "g"

// Chunks

char 5 of "str" is "n"

In the 1990s as a happy HyperStat user, I exchanged occasional mails with him. 
When I later discovered Metacard, I mailed him in some excitement hoping he 
would port HyperStat to it, but he was already committed to web.

I will certainly have a further nose around…

Generating Random numbers to conform a distribution

[David V Glasgow via use-livecode]

Quite a lot of stats and maths packages offer a feature whereby the N, the Mean 
and the SD are variables specified by the user, and N random numbers are then 
generated with the required mean and SD.  I remember the venerable and 
excellent Hypercard  HyperStat 
 (1993) by David 
M Lane doing exactly that.

In general terms, how do they do this?  One option would be to ‘pair’ each 
random number with its reciprocal around the mean, but that would generate 
perfectly symmetrical distributions, not to mention is only half random.

Alternatively you could ‘aim’ at the sum and do a little series of kludges at 
the end of the RND generation.  Ugly and cheaty, and neither addresses the SD 
challenge

Or is there an elegant formula?  I have Googled about and can’t see one, but 
maybe I don’t know the magic words.  And if someone wanted to script this in LC 
what would be the best approach? (just general guidance here, wouldn’t want 
anyone to invest their valuable time in what is at present just vague musings)

Any hints from the stats gurus?

Cheers

David Glasgow

Re: Encountering slow navigation to a card containing very large fields? Do this one simple trick.

[David V Glasgow via use-livecode]

Maybe context would help.  I receive digital evidence from police Hi Tech Crime 
Units, consisting of lists/tables of messages, search histories, web histories, 
files downloaded, etc etc.  These relate to online activities of alleged 
internet offenders. Some consist of data relating to a few months activity, 
others may be 10 years or more - so vary hugely in the sheer quantity of data. 
This is what is imported into the first field.

 I have established a number of sets of keywords/tags  which can be cycled 
through using ‘filter with’ to find list items which might indicate particular 
forms of malign motivation of the alleged offender. So, a user clicks button 
“Filter with X keywords” looking for, for example,  coercive/aggressive tags.

All ‘filtered with' lines containing selected tags appear in the second 
scrolling field. Sometimes nothing much will be found, but sometimes this field 
may become 50 to 74% the size of the field containing the original  imported 
data.  This (second) field can be scrolled and eyeballed until something of 
forensic significance is spotted.   Clicking on that line scrolls the first 
field to display and highlight the line in its original context (i.e showing 
preceding and following lines).  

With respect to Bob’s observation about the work to display a background group 
being 'already done’ if the navigated-to card contains the background group 
containing the field, that is pretty much what I assumed is happening.  The 
intriguing question is why the work necessarily  is ‘undone’  when navigating 
to any card not containing the group.  Does it consume such significant 
resources the default is to clear it?  It would be nice to be able choose to 
preserve or cache the work if that has such a significant impact on performance 
as in this case. 

Best Wishes,

David Glasgow

Yup, I do that.  processing takes time, but honestly it is amazingly fast.  
Dumping found lines into the results field takes a surprising amount of time, 
but even that doesn’t bother me too much.  The issue is purely navigating back 
to the card containing the 600lb fields from any card that doesn’t.

Typically 30,000 to 800,000.  One field wrapped (the imported ‘source’ text) 
and the other a, unwrapped list of found lines containing a keyword.

The wrapped line field is locked and doesn’t change after import and is 
unaffected by the  keyword-containing-lines process.  I suppose a good question 
is are line wraps recalculated on navigation to the card.

Re: Encountering slow navigation to a card containing very large fields? Do this one simple trick.

[David V Glasgow via use-livecode]

Hi Jim,

The text in fields doesn’t move or change after the initial analysis. the 
slowdown is just navigating back to to the card containing the fields from from 
one which doesn’t contain the fields.

Re: can I filter lines with a list of alternative OR strings?

[David V Glasgow via use-livecode]

Thanks, Dick!  I’ll play with that and see how I get on.  The filter is in a 
loop which mostly uses simple strings, so presumably I would need to separate 
any regex filters into a separate loop using 'with regex'.

I have also learned that this is called “alternation”.  Didn’t know that, so 
now I can investigate further! 

thanks again

Re: Text overwriting itself in non wrapping field

[David V Glasgow via use-livecode]

Fixed line height didn’t fix the problem but thanks for the suggestion.

However, looking more closely there are 3 visible characters where cr should 
be.   They are â9u except 9u is constant and the first character is almost 
always there, but varies wildly.  Often an underscore but also accented a, e or 
u.  Even more weirdly, if I search the field for ‘9u', several lines are found, 
but not any in the mutant line.  

And yet more weirdly again, when the line is displayed in a field with wrap 
true, the weird three characters appear at the beginning of ‘new lines’ except 
they are not actually new lines because they highlight as a single block.  An 
invisible form feed?  or something else between 9 and u  that a wrapping field 
decides is a wrap point but confuses the hell out of a non-wrapping field?

If I thought this was just a weird one off, I would shrug my shoulders and move 
on.

Shall I do that, and we will never speak of this again?

Best wishes,

David G

Text overwriting itself in non wrapping field

[David V Glasgow via use-livecode]

Hi folks,

I have imported just under 10,000 lines of a web history into a non wrapping 
scrollable field.  As the subject above indicates, in one line characters 
appear rendered over the top of each other.  The is quite stable, so redrawing 
or scrolling doesn’t make it go away.

That line is pretty long, but not longer than field limits - 10693 chars

Examining it, it looks like it ought to be a number of separate lines, and it 
also contains weird visible and also white space that is not a simple space.  I 
can’t see any recognisable pattern to suggest where cr should be.

Any suggestions about what is going on and how I might fix it?

Cheers

can I filter lines with a list of alternative OR strings?

[David V Glasgow via use-livecode]

Hi Folks,

I can filter text using a single term plus a numerical range s eg:
*re 1[0-5]*
matching a text stem “re “ followed by any one of 10, 11, 12, 13, 14 or 15 

But is there a form where the alternatives are also text?  eg something like:

*big [“dog”, “cat”, “fish”]*

The above searches OK, but only for “big”.  There is no error, but the 
parenthetic list is ignored, I think.  A number of lines 'filtered with' 
contain the stem but none of the listed suffix strings.

I suppose there is also a supplementary question that if there is a list of 
alternative strings  option, is it more efficient than filtering for "big dog", 
big cat, etc in turn?  If the option exists I feel like it ought to be faster, 
but what do I know?

Cheers

Re: scripted Show tooltip not a thing?

[David V Glasgow via use-livecode]

I rather lazily didn’t post an update, but on reflection I had already decided 
to do exactly what you recommend, Richard.  

Your advice isn’t wasted because my thinking about why it is the best thing to 
do wasn’t that clear.  It is an important UI point you make about advice only 
being  useful as an antecedent of choice.  Also, since I have avoided flippy 
flappy tooltips in my rather control-crowded app, it makes zero sense to have 
one exception which users would have no knowledge of, or reason to find until 
they stumble upon it.  And then maybe wonder why the same doesn’t happen 
elsewhere.

Why is it so easy to design a bad UI, when it is such a pleasure to experience 
a good one?

Thanks,

David G

Thanks all.

I scripted as if the delay was the duration the tooltip is displayed.  Duh!  Of 
course the delay is hover delay before the tooltip shows!  I knew that, and yet 
somehow didn’t know it at the same time.

Re: screen resolution and stack height

[David V Glasgow via use-livecode]

Thanks for more thoughts guys.  I do have a scale factor button, but don’t want 
to stretch, so I use ‘letterbox'

The cinematography web page inspired me to experiment more freely and I found 
that 3:2 seems to be a good compromise despite not matching any screen 
’standard'.  It scales on screens pretty well, and fits reasonably well printed 
onto a landscape A4 page, which is about 2.82:2

It is matches the aspect ratio of  DSLR sensors and classic 35mm film, which to 
my eye at least, looks lovely.  Perhaps because it is very close to the ‘golden 
rectangle’ (3:1.85).  That could just be me being a bit bonkers, but it would 
be interesting to know if there is more widely felt appreciation of certain 
aspect ratios.

So for now I am going with 1200x800

Cheers, & thanks again

Interesting!  I suppose my original point is that in the old days you could 
create at any intermediate ratio and it would match or scale nicely to fit the 
screen.  

Is there a larger ratio that works similarly?(I suspect not)

Alternatively, I will take the recommended anarchists’ solution and make it the 
best dimensions for the task.

Thanks for the advice folks.

Re: On the subject of things with the same short name... ('identical' groups which behave differently)

[David V Glasgow via use-livecode]

Ah! (light comes on).  Thanks Sean.  So ‘me’ is actually more specific than it 
would seem!  I avoided ‘me' because it returns the short name of an object (of 
which there are several), and went for the long name of me because it is 
unique.  

Just to be clear, what you are saying is that when LC searches for ‘me’, the 
first one found will always be the target, and the search stops there.

I still don’t understand why rect (the rect of the long name of me) works in 
one but fails in another group, though.

Cheers,

David G

So if someone  has a cross platform (Win/Mac) app designed to process text

Re: Text encoding.

[David V Glasgow via use-livecode]

Following this with interest, but also a little confusion.  I completely fell 
into the trap of assuming you encode outgoing and decode incoming.

Alex states that put textEncode(tWHoleText, "UTF8") into tWholeText speeds 
replace up, but David B says LC internal format is UTF16.  Doesn’t the 8 vs 16 
difference matter?  Or matters less than other encodings?

Re: Replacetext of any characters between parentheses with a space

[David V Glasgow via use-livecode]

Ha! Another way.  I couldn’t get the regex to work, despite Paul's invaluable 
help reminding me that replacetext  is a function.

My cobbled together solution involved setting itemdel to parentheses then 
deleting items.

As the Grateful Dead rather repetitively put it:

So many roads
So many roads 
Mountain high, river wide
So many roads to ride
So many roads
So many roads

(in LiveCode)

Replacetext of any characters between parentheses with a space

[David V Glasgow via use-livecode]

LC coders, please tell me why this won’t work!  My guess is that this is a 
regex issue, not LC, but I am so stuck.

I want to replace all text within in parentheses (including the parentheses) 
with a single space.  I have tried assembling the matchExpression in advance 
and in line, and also escaping the parentheses just in case they are reserved 
in regex.  Or do I need to enclose the matchExpression in something other than 
or in addition to, quotes?

on mouseup

  put field "import" into timport

  replacetext (timport, "(.*)", " ")

  put timport into field "import"

end mouseup


I get the less than inspiring:

 execution error at line 3 (Handler: can't find handler) near "replacetext", 
char 1

Finding invisible/non printable characters in a string

[David V Glasgow via use-livecode]

Hi folks, hope everyone is well.

Would I be right in thinking if codepoint count > the number of chars in a text 
string, then it probably contains invisible characters?  

Or would I need to search through Hex to check?

Or something much easier and cleverer that I hadn’t even considered.  Because 
that’s what this list and working with Livecode is like.

Hmmm maybe I have just completely misunderstood. The parameters dictionary 
entry for export snapshot says:


object: Any valid object reference.
size:   The width,height of the snapshot in pixels.
metadataarray:  The metadata is an array of metadata. Currently the 
only key supported is "density" with a value in pixels per inch (ppi).

import snapshot parameters include rectDescription and stackRef, then :


objectRef:  Any valid card or control object reference.
sizeDescription:The width and height of the snapshot in pixels, 
in the form height,width.

no mention of a metadata array

Snapshot image density

[David V Glasgow via use-livecode]

Hi Livecoders,


I have been thinking about offering snapshot image density options on an app 
which currently only offers (import) snapshot size options.  I chose import 
snapshot script variant because users’ machines may well react badly to an 
attempt to save an image (security).  However, most of the software they use 
will allow a clipboard image to be pasted into a record.

First question:  Is it right that import snapshot doesn’t offer image density 
options as export snapshot does?  If that is correct, (it is what the 
dictionary on 9.6.0 shows) question the second….should I just export to the 
temp folder, immediately import, copy to clipboard and proceed as before?  Or 
is there a more elegant route?  (I suppose there is also a question 2.5, are 
temp folders always available irrespective of the severity of security 
restrictions which might be imposed?)

The density options I want to offer are 

Screen (96 DPI)
Print  (300 DPI)
Publication (1000 DPI)

3rd (double barrelled) question… Would the correct syntax to set up for 
publication density be

'put 1000 into snapshotArray[“density”]’  

and then to actually capture…  

'export snapshot from objectref with metadata snapshotArray[“density”] to file 
“SeeSR.png" as PNG

I would investigate myself if I had the time, but sadly I also have to earn a 
living through my day job.

BPD EUPD

[David V Glasgow via use-livecode]

Not going to get all professional/technical here, but this condition is 
*really* tough on those who have it.  Think social-emotional roller coaster.

It also generates challenges for those who interact with them.  What allowances 
individuals choose to take is a matter of choice, of course.  However it seems 
to me it would be useful for some consideration from list-parent.  Not a 
license to offend gratuitously, but equally I would be more than happy for 
there to be encouragement to repair off list rather than the usual threshold 
for list off-booting.

Re: Star score graphic generator achievable with inks... or...?

[David V Glasgow via use-livecode]

Thanks, but Bob Sneidar was exactly right in his original post.  His solution 
works beautifully with real numbers represented as part stars.  I did look at 
the segmented widget, but I wanted to represent real numbers from averaging 
customer ratings.

The only teeny  limitation is that between each star there is a small gap in 
which ‘between stars’ scores are not displayed until the threshold of the next 
stars leftmost point is reached.

In terms of the typical web display of customer feedback, it isn’t significant.

Cheers

Thanks,Bob,  but as I understand what you are saying, wouldn’t that only trade 
in whole stars?  The easiest way to do that would be with icon switching - I 
want to have the last star part gold and part grey, (with a  vertical boundary 
through the star) if that is what is demand by the mean feedback score being 
represented.

I’m thinking perhaps icons will be the easiest way to go.  Maybe 10 stars each 
representing a degree of  ‘goldness’ and I will just set the stars Icons as 
required.  Duh!  Actually 11 stars, I will need a 0% gold.

Thanks anyway

Star score graphic generator achievable with inks... or...?

[David V Glasgow via use-livecode]

Hi folks,

I am thinking about an app to create a 'star score' graphic for any given 
score/maximum value.

I don’t want it to be just integers up to the number of stars, but for one for 
the stars (if mean score is neither zero or the maximum) to be part golden and 
part grey.

I initially thought this would be straightforward but I am now scratching my 
head.

I was wondering whether there is an ink combination of two graphics (star and 
‘screen’) which would allow the covered part of the star to appear grey but the 
card bg  behind the screen to be unaffected.

Please assume I really don’t understand inks at all.  If that isn’t going to 
work, any other suggestions?


Best Wishes,
David G

Re: Resources folder on mac, and the good old days

[David V Glasgow via use-livecode]

I am following this with interest because, as I have previously lamented, I 
would like to give away apps to colleagues without the huge, incomprehensible 
headache of certificates, signing and notarising etc.

I want to make absolutely sure that I understand it correctly, that a player 
app which was enabled to run on a machine (either by user or the more formal 
method) could be designed to list and run any number of stacks distributed as 
stacks, and placed in a designated folder or sub folder.

If correct, doesn’t that:

A/  Enable distribution and updating of any LC ‘app’ simply by the prospective 
user dropping it into the correct folder?  (AKA ‘the good old days')

B/  Undermine the fundamental intention of certification in the first place?  
(Personally, I would trust Livecoders, and indeed often run posted stacks 
without a second thought, but what if Richmond* went over to the dark side?) 

Cheers

David G

 Same here. Not that I've every liked that paradigm, just that it's been 
 that way since life crawled out of the ocean.
 
 However this should do the trick.
 
 if tArray["status"] is an array then
 put tArray["status"]["text"] into tStatus
 else
 put tArray["status"] into tStatus
 end if

Baffling can't create variable message

[David V Glasgow via use-livecode]

LiveCoders,

I have a pulldown menu button to which I want to append new searches that it 
does not already contain.

I have scripted this in various ways, multiple lines, single line, add 
parentheses, leave ‘em out, use extra variable/not,  in an attempt to isolate 
what I am doing wrong.  Sometimes I get a missing ‘then’ error, when it is 
clearly present.  However, in several constructions of the script, including 
the one liner below, I get

 “Can’t create a variable with that name (explicitvariables?) near text, char 
113

The script is:

if the text of button "Search All" contains field "custom" = false then put 
return & field "custom" after the text of button "Search All"


I'm doubly confused because a) in this version of the script I am not using 
variables, and b) Strict compilation mode is unchecked.

I have no idea whether this is a clue, but only commands seem to be colourised 
in the script editor.  I also noticed that the breakpoints tab reports a 
breakpoint on line 54 (which doesn’t exist), and which I have never knowingly 
set.

LC 9.6.0 MacOS 10.13.6


At this stage I would welcome someone pointing out  a palm->face rookie error 
rather than anything more sinister .  


Best Wishes,

David Glasgow

Re: [OT] Poll: What does it mean for 1 rect to be 'within' a certain distance of another rect?

[David V Glasgow via use-livecode]

Well, my suggestion a non starter if you need to do hard sums, and you eschew 
invisibles. 

However, my thinking was this... I understood that the task was to detect when 
two rectangles r1 and r2 were within distance d of each other.   Presumably 
ether a flat bit or a pointy bit, coming in at any angle.  if each rectangle is 
centred and grouped with a rect that is bigger by d/2, any intersection of any 
two bigger rects means that the smaller corresponding r1 and r2 rects are at or 
within the desired distance d (half d measured by r1’margin over r1, and half 
by r2’margin over r2). The size of the groups is ignored, and as long as all r 
& r’ stay centred it should work, unless the rects move super quickly.

Oh.  It just occurred to me is that the bigger rects would have to have rounded 
corners.  Hmmm.  


OK, I’ll just sit back and see how it should be done.

Cheers

David G

Hi Sean,

I think that kind of aspirational statement, particularly in the world of 
software development, is the kind of thing to be really pleased and surprised 
about if it actually happens within 12 months of the estimate. In my book it 
certainly doesn’t qualify as a lie.  To anticipate features for a commercial 
product in development would need  a seriously strong and informed insider 
steer.  No consolation, I appreciate, but if anyone should be in a position to 
understand the particular challenges of software development, it must be other 
developers.

Which kind of reminds me about my last mail…. paying for Windows SuperCard and 
waiting for it to arrive.  I was SO wound up about that.  Weirdly now, it is a 
fond memory.

David Glasgow

I intended to comment on list, because I was impressed with Videolinkwell and 
thought folks on the list might be interested!

 I watched the videos and think your app is really cool and worthwhile.

There!  I did it again!

Re: Cmi5 eLearning Standard in LiveCode MEETING TODAY AT 1 PM EST

[David V Glasgow via use-livecode]

VideoLinkwell looks like a great tool, Martin.  I spend a lot of time analysing 
video recorded police interviews, so I I know what a huge slog it is to 
document what happens and at which point(s) in a video.

Is there a walkthrough of features/tools?

Field ID clash

[David V Glasgow via use-livecode]

Using 9.6.0 on Mac 10.13.6

I duplicated a field and found a third field responded to the mouseup of the 
duplicate.  It seems the duplication generated a clash of IDs between the 
duplicate and third field.  I could just select and start again, but I was 
wondering whether there is a safe way to manually (or force automatic) change 
the ID of one pr other of the fields.  I also wondered how this might happen in 
the first place.  Is my stack OK, or might a more serious problem be 
developing? 

Any thoughts or suggestions?

Best wishes,

David Glasgow

Re: Design Question

[David V Glasgow via use-livecode]

Oooh!  For once I might make a contribution!

I had the same issue in a healthcare context.  These IT systems vary 
tremendously between services, are complex and often hard to connect with - 
either by design, or by lack of interest in supporting other software.

I found the best way to get a combo education and training/clinical app to be 
accepted was to create it with no dependencies (local or online), no attempt to 
connect with management systems, no writing of data anywhere, just the ability 
to copy and paste charts and data that nurses can incorporate into other 
reports.  Although clinical information systems are hostile to most actions, 
they have to allow pictures (like x rays and other scans) and spread sheet data 
to be pasted into the record.  Ironically, they almost all allow Word documents 
to be incorporated into the clinical record too.  Nurses don’t need to be shown 
how to do these things, because they wrestle with ugly, poorly designed 
clinical information systems on a daily basis.

In other words, you’re on the money, I think.

Getting page counts of PDFs

[David V Glasgow via use-livecode]

Livecoders,

In my day job, some of my income comes from the number of pages from  a number 
of PDF documents thatI have to read for individual cases.  I thought it would 
be fun and useful to write an LC script that would either count the pages or 
(even better) get the page count of a folder full of PDFs.

I didn’t imagine it would be too hard, because both Mac and Win OSs report page 
number instantly and accurately in the file information windows.

I discovered that in a small sample of PDFs a line… 
<< /Type /Pages /MediaBox [0 0 612 792] /Count 149 /Kids [ 1396 0 R 1397 0 R


...contained the page count, which was a bit confusing because I read that the 
Mediabox was only about page dimensions.  Then I found that some PDFs don’t 
contain that line, or at least not in the clear.

There is a general online consensus that reliably finding the page count of a 
PDF involves quite a lot of messing about and parsing, and may involve pretty 
much counting the pages.

I found some code here  with 
the following walk through:

//1.  See if there's a 'Linearization dictionary' for easy parsing.
//Mostly there isn't so ...
//2.  Locate 'startxref' at end of file
//3.  get 'xref' offset and go to xref table
//4.  depending on version the xref table may or may not be in a compressed
//stream. If it's in a compressed stream (PDF ver 1.5+) then getting the
//page number requires a LOT of code which is too convoluted to summarise
//here. Otherwise it still requires a moderate amount of code ...
//5.  parse the xref table and fill a list with object numbers and offsets
//6.  handle subsections within xref table.
//7.  read 'trailer' section at end of each xref
//8.  store 'Root' object number if found in 'trailer'
//9.  if 'Prev' xref found in 'trailer' - loop back to step 3
//10. locate Root in the object list
//11. locate 'Pages' object from Root
//12. get Count from Pages.


If this is right, how on earth do OSs do it so quickly?  Also, and more to the 
point, am I on a fools errand to do this with LC?  I haven’t seen anything that 
obviously couldn’t be done (didn’t understand the regex, but assumed with 
effort…).  However parsing huge files just doesn’t look like it would be worth 
the effort, particularly as I can select all the documents,  get info, and sum 
the pages in my head..

Cheers,

David Glasgow

Re: sorting lines by date

Thanks everyone & Curry.  I will play with this some more.  Looking at the 
lists I am given, most of the date columns are declared to be UTC.  I intended 
to try to detect other formats in due course, but thought I’d start with the 
common one.

Reminds me of my favourite Jake Peralta line: “Stupid rest of the world, 
writing their dates all dumb!”

Hi Tom,

That’s what I thought I was doing.  From the dictionary…

The dateTime keyword recognizes all LiveCode's date and time formats and sorts 
them in time order, rather than alphabetical or numeric order.

sorting lines by date

I am working with text files consisting of many thousands of lines, most of 
which are in the format URL & Tab & Date - but a few don’t have a date.

So they look like this ...

I assumed I could sort the lines by date using the following:

set itemdel to tab
sort lines of field "import" datetime by the last item of each

(I know I could speed this up using a variable, but I wanted to just see the 
result first.)

I wasn’t sure what would happen to the lines with no date, but assumed they 
would pile up at the beginning or the end of the field (which would be fine).  
However, what happens is that the script runs, and the order above is 
generated.  I can’t see any meaningful ordering of the lines.

I have a horrible feeling that dates are more complicated than I imagined, 
although I am sort of hoping  there something simple I just haven’t grasped.  
If so, what?

Best wishes,

David Glasgow

Re: slow loading & navigation to card containing large field

[David V Glasgow via use-livecode]

Hmmm.  Food for thought both!  

Loading I just use 

put URL ("file:" & theFilePath) into tdata

I have always assumed that reading as binary is only for data that isn’t  text. 
 I’ll try that. If I want to display some or all of the file in a field, do I 
need to process the data read as a binary, or can I just put it into a field?

So far I have worked on the principle that users should be able to see the 
effects of their searches, etc, so have defaulted to field.  Maybe I could 
store part of the list in the field (and swap in/out out as users scroll 
through) but do the main storage and heavy lifting within a custom property?

Thanks very much for the suggestions.

Cheers,

David G

slow loading & navigation to card containing large field

[David V Glasgow via use-livecode]

Hello LCers

On Mac 10.13, LC 9.6

In my stack I have a field on one card consisting of imported text, which is 
typically several thousand of internet searches/file names/URLs.

I search for a number of  keywords, which are then aggregated, and by 
navigating to another card, display summary statistics  on the content 
analysis, in the form of a bar chart displaying the top 20 found terms.  So not 
a lot of data on the charting card.

I have a fairly extreme case of 781,000 lines (80,988,686 chars) in the content 
analysis field, consisting of a web history.

I am amazed at the efficiency of the searching process, which takes a while, 
but is as fast as I could hope.  It is slower than earlier versions, but the 
memory usage stays very steady, which wasn’t the case in 8 or early 9.  I’m 
happy to swap a bit of speed for more stability.  The content analysis works 
nicely, the transition to the chart card and chart displays quite quickly.

I have 2 problems:

1/ Loading the plain text list of URLs from file is slowish, but more 
importantly, for some time gives no indication that the file is loading.  After 
selecting the file, there is a long pause before the cursor becomes the OS 
beachball, another long pause and then eventually the card and populated field 
appears.  Is there any way of letting users know that this 82MB file *is* being 
loaded, they just need to be patient?  Or am I wholly in the hands of the OS?

2/  Navigating from the chart card back to the card containing the big list of 
URLs is very slow, typically taking about a minute from the mouseup on the 
navigate button (or command from message box).  A précis of the message watcher 
shows the delay occurs between the consecutive closeBackground and cREVTable 
messages below.

mouseup 3:55:45 PM (1)

closeCard 3:55:45 PM (0)

closeBackground 3:55:45 PM (0)

cREVTable 3:56:43 PM (58144)

opencard 3:56:45 PM (22)

(In the preopenstack of the big field card, I hide a group containing 9 fields 
each containing maybe 30 words - nothing that should take much time)

Am I just asking too much of LC, or are there any suggestions about making the 
transition between cards brisker?

Fwd: Build problems with 9.6 [mostly fixed]

[David V Glasgow via use-livecode]

I never saw mail below  reach the list, and received no replies, so I am trying 
again.  

Aside from thanks to Panos, I reported  a new problem with an error “could not 
auto-detect inclusions or security categories because stack is password 
protected” when I don’t think it is password protected.  I tried setting the 
password of the stack  to empty, with no change to error.  Stack has no sub 
stacks. I suppose I could select inclusions manually, but it would be nice to 
know what is going on.

Cheers,

David G

Re: Build problems with 9.6 [mostly fixed]

[David V Glasgow via use-livecode]

Updating to Xcode 10.1 did the trick, so it looks like something had gone awry 
with the previous Xcode install.  I really hadn’t  appreciated that there is 
any LC dependency on Xcode with respect to desktop builds.

Thanks for the advice Panos.

I now get a build, but with the warning “could not auto-detect inclusions or 
security categories because stack is password protected”

This didn’t happen in 7.x or 8.x, and as far as I know, the stack is not 
encrypted.  I have seen a discussion of the same message with a script only 
stack, but I couldn’t see any real connection with my case.  

I tried 

set the password of stack "ISOPtex" to empty

in the message box, but still got the same message on build.

Any suggestions anyone?

Thanks David G

Oh boy.  Feel a bit dumb now!

Currently 10.1, downloading 11 now, just in case.

response this time 

You have new mail in /var/mail/mrdglasgow

… which was a report.  I searched for ‘error’ and there were none, but 
launching Xcode resulted in the same error as before.

Is it worth trying a build with LC, or should I install Xcode 11?

Cheers

In response to this I get

xcode-select: error: invalid developer directory '/path/to/your/Xcode.app'

Launching X-Code I get an unknown error with a long field of text in the 
console.  Want to see it?

Build problems with 9.6

[David V Glasgow via use-livecode]

Hi Folks,

I have been trying out 9.6 on Mac on a stack developed with 7.1.4.  I made some 
minor tweaks to the stack and then tried to build a standalone.  I didn’t check 
change the default build settings.  It built for linux, then entered a blizzard 
of 'stack with the same name is in memory’ alerts then crashed.

I relaunched and switched off builds for Win, Mac 32 bit and Linux, so building 
just for Mac 64 (which was all I wanted).  Build for mobile both unchecked by 
default

This failed with the following error(s)

There was an error while saving the
standalone application

Adding ad-hoc signature failed with error:
/Users/mrdglasgow/Dropbox/Rev
Dev/ISOtex/Forinan12/Forinan.app:
replacing existing signature

Agreeing to the Xcode/iOS license requires
admin privileges, please run xcodebuild -license,All and then retry this
command.

/Users/mrdglasgow/Dropbox/Rev
Dev/ISOtex/Forinan12/Forinan.app: the
codesign_allocate helper tool cannot be
found or used

Que Pasa?  This isn’t for distribution or anything, and I have never tried to 
sign anything previously built.

Re: Unicode and languages

Ha!  You beat me to it, Alex.  The only extra is that Paul might be able to

Made me wonder how Google translate does it when it is set to 'detect language’

Re: Any electronic document formats offering interactivity?

[David V Glasgow via use-livecode]

Thanks for responses.

I should have been clearer.  As usual.

The interactivity within LC is no problem.  The user effectively creates a 
‘dashboard’ profile representing their own assessment of multiple risk factors 
at play in a particular case.  Currently, a representation of the resultant 
profile can then be captured as static image or PDF.  To keep the dashboard as 
clean as possible, within the app, explanatory notes are hidden unless labels 
are clicked.  I was wondering if it might be possible to retain just this 
aspect of functionality.  So someone viewing previously saved profiles could 
access pop-up explanatory notes.  It seems to me that PDF could offer that, but 
1 it is hard to do and 2 many PDF viewers don’t offer the interactivity 
promised by Adobe.

I did briefly consider HTML, but wanted to deliver a single file as the output, 
and an image of the dashboard profile is essential.  

An alternative strategy I think is going to be preferable, would be to save 
locked cards to a ‘results’ stack as the output format.  I was kind of hoping 
minimally interactive profiles could be saved in a more generally accessible 
format, but it seems (once again) what is easy in LC is blimming tricky outside 
it.

Cheers,

David G

Any electronic document formats offering interactivity?

[David V Glasgow via use-livecode]

Hi folks,

I would like to be able to generate a document from LC consisting of a single 
page (effectively a copy of a card) which can offer some basic interactivity. 

I would be pretty happy if users can create a document that would display 
‘tooltip-like’ explanatory notes if summary fields are clicked.

I couldn’t make any sense of the interactivity offered by PDF.  I did a bit 
better with ePub, but the emphasis seems to be on links, animation and video 
etc, which is far more than I want.

Any advice or suggestions?


Best Wishes,

Re: [macOS] Notarization, hardened runtimes, LCB, and executables

[David V Glasgow via use-livecode]

I have to say that this fills me with despair.  I try hard to  write serious, 
useful  programs, for fellow professionals,  but I am not a developer by trade 
or training.  I have a full time job, which subsidises my time using LC

The beauty of LC (and Metacard before it)  has always been how amazingly easy 
it is to write something genuinely useful and share it with others, pretty much 
irrespective of platform.  I used to just share with colleagues via DropBox.  

Now I look at an app I have developed and realise I have neither the time or 
technical ability to navigate through certification and notarization.  

Is this the beginning of the end for enthusiast developers?


Best wishes,

David Glasgow

The wonderful “Owner” is the property you’re after, I think.

Hope that is useful.  If it is, possibly my first time!

Re: How does OSX tell what app to open when you double click a file?

[David V Glasgow via use-livecode]

No idea if this is any help at all, but I run two versions of Apple Pages (I 
have my reasons… ;-)

I have the older version set as the default for all Pages documents, and make 
exceptions when I need to.  Interestingly, MacOS 10.13.6 gets confused 
sometimes.  Even if a document is set to open with the newer version, some 
launch the older version.  Can’t always see why.

They also always open with the older version, if that version is already open, 
irrespective of the setting in Get Info.  Except if you use “open with” 8.1, 
then the later version is launched and used.

I have also noticed that some docs are set to open with the older version with 
the text in the get info 'open with' drop down menu saying 

Pages (Default) (4.3)

Whereas others just say

Pages (4.3)

I can’t work out if there is a difference between the two, but the drop down 
menu also normally offers 

Pages (Default) (8.1) 

Which is only effective if 4.3 is not open

So this looks like a dark art not even the Apple Developers have mastered.  
Although I guess they would argue that no one in their right minds runs more 
than one version of the same app. 

Cheers,

David G

Re: Do variable vs field as AppleScript

[David V Glasgow via use-livecode]

Thanks, Bob, that’s what I suspected.

From the UI point of view, its just feels a bit clunky - combined with being 
uncertain about whether the speechrecognitionserver is still working or whether 
recognition has failed, and whether the human  needs to repeat the phrase or 
not.

Maybe I am conflating two issues, but I wondered whether I could get it all to 
be a bit more brisk.

Cheers,

David G

Do variable vs field as AppleScript

[David V Glasgow via use-livecode]

I have a script which in the fullness of time will repeatedly (several hundred 
times) run a list of commands as an Applescript.  It will take a fair bit of 
time to loop through because each iteration involves speech recognition.

My question is, will there be any meaningful speed advantage to storing the 
AppleScript in a variable rather than field?  This doesn’t mean finishing all 
340 iterations faster, because the slowdown is the human thinking about the 
question and giving a response.  I’m thinking about a bit more responsivity 
from 

tell application "SpeechRecognitionServer"
local tresult, choicesLanguageModel, titem
set choicesLanguageModel to {"false", "slightly true", "mainly true", 
"very true"}
set tPrompt to "item 6"
set tresult to listen for choicesLanguageModel with prompt tPrompt 
giving up after 30
say tresult
return tresult
end tell

(I should say that the line "set tPrompt to "item 6”” looks a bit weird because 
it is incremented under script control, and when that happens the indent is 
lost.)

I know I could test, but if someone just knows….

Cheers

Re: teeny tiny answer dialog text on Windows

Yeah, I did wonder that, too.   On openstack (mainstack ) I set the font to

teeny tiny answer dialog text on Windows

[David V Glasgow via use-livecode]

Hello, folks.

Having returned to work on an old stack I have found that whereas standalone 
answer dialogs look fine on Mac, on Windows (10) the text (eg. “Do you really 
want to quit?”) is so small it is barely legible.  (Building on Mac 10.12 and 
10.13)

I set the font to Arial, so although I would expect some font difference, there 
won’t be  problem with missing font.  I also built standalones with LC 7.x and 
8.x, because I seem to remember that fonts changed in some way in LC8.  No 
obvious difference between them, and no improvement.

Before I resort to setting font size via HTML in script for each dialog in 
turn, any suggestions for a  global fix?

Thanks

Best Wishes,
