Windows library can not.


Do you ship your app as a 64-bit windows exe?

I wonder if its just a limitation of the library we use when compiled 
for 32-bit archs...


Warmest Regards,

Mark.




I thought you had nailed it as we build both 32 and 64 bit Windows EXEs 
and I might have been testing the wrong one, but I just rebuilt the app 
using LC 9.6.8 for 64-Bit Windows only (turned off the 32 bit build) and 
retested and get the same error as in the bug report occurs. ZIPs under 
2GB unpack fine. Over 2GB produces the error "ziperr,Can't open file: 
Unknown error" as the result for calling revZipOpenArchive pArchive, 
"read" where pArchive is the filespec.


I think we'll just add a file size check on Windows and advise that that 
customers will need to use a OS or 3rd party ZIP tool to move their 
research data if over 2GB.


For many of our customers, this will never be an issue as their total 
research data will not even come close to 2GB. Some of our customer are 
using video data, and for them, a single video source (used for their 
research) can easily be over a GB itself or even over 2GB by itself. A 
research study can consist of several (or many) such sources.


Unfortunately, with multi-mega pixel phones these days making capturing 
a lot of video very easy more researchers are using large video files in 
their research.

Re: RANT (Mild): revZIP library

2022-10-11 Thread Paul Dupuis via use-livecode

Thank you for the history.

Yes, using other ZIP tools via shell is a possibility, but one I would
rather not do. While some researchers who use our app are very computer
savvy, most are not. Having a LiveCode ZIP in a window with a nice UI
that uses terminology our data analysis tool already uses to let them
'package' their data works well for usage and adoption.

We're already doing invisible shell work-arounds for a number of engine
bugs, with using ffmpg to replace Export Snapshot (see
https://quality.livecode.com/show_bug.cgi?id=23694) the latest. I would
just rather not add another 'work-around'. I was actually spending time
today cleaning out an old work-around from when a minimized stack set
one of its coordinates to -32000 as a way of indicating it was minimized
(before the iconic property existed) and work-around fro when a stack
was minimized it would get a 'resizeStack' message with a new width and
height of 0,0. None of these apply any more but we don't always have
time or awareness to remove work-arounds when they are fixed, which can
sometimes be years after the work-around was put into place.

Anyway, thank you for the suggested approach. It is actually really goo
to know someone else has already done it.

Hi Paul

I got affected by that and other win revzip issues too. I ended up parsing them
through a shell script and using windows built in unzipper. Of course the
downfall with that is a lack of feedback on progress which, for large files
like this, requires a great deal of time to process and feedback is almost a
necessity. I made the shell visible just so that the customer was aware of its
progress. It was ugly in terms of UIX but it got us out of a short term hole. I
hope you can get a more long term solution.

I’m sure you’re capable of building the shell script but let us know if not.

ever imagined a chart could do, and more. (*)

The Chart widget is a wrapper forChart.js v3.7.0

beautiful and highly customizable charts, in a simple way. Data can be
displayed as a line graph, bar chart, radar chart, donut/pie chart,
polar chart, bubble chart or scatter plot.

It really is wonderful - all kinds of charts, very fast, animations,

date sequence charts needs some extra magic, and I don't know how to
find that magic.

Thanks for the suggestion of reading the .lcb; I probably couldn't have
made sense of it anyway - but there is no .lcb file for the chart widget.

It's just my bad luck that all the charts I want to do are the kind that
is beyond me :-)

Anyone using this widget ?

Is there some documentation (other than the obvious dictionary entries)
about how to do different kinds of chart ?

In the last 4-6 months, I've done 3 or 4 little personal projects where
I wanted to create a chart, but I've not been able to figure out how to
use the charts widget to do time-based charts.

What I mean is, e.g., create a chart for the following data

2022-02-01100
2022-02-04500
2022-02-05525
2022-02-17900

Obviously, the dates along the X-axis should be spaced properly
according to their data value, not equally spaced and simply labelled.

Looking at the charts.js documentation, it tells me (or rather, fails to
tell me, since I can't understand it) that I need to define an 'adapter'
and shows some sample javascript. I don't really understand how to do it
simply in javascript - far less how I could use that in the widget.

Can anyone give me a clue or a pointer ?

Many thanks,

Alex.

P.S. currently I solved it using my own GraphMaker library (see LC
conference from 2018) - but I'd really like to retire that library in
favour of the new widget.

Where the heck is the chart widget (com.livecode.widget.chart)?

If so, this is a terrible disadvantage of any use of widgets. I feel I

In our applications, we trap the script error dialog and replace the

executionContexts and some other debugging information to us to report 
an error (if one gets by quality/beta testing).


So we get the executionContext that say "error such and such occurred at

script the handler is in.


When we et the message and log the problem in our instance of Bugzilla, 
one of the 1st things is to look at the script and see what the line of 
code references actually says.


It could reduce a trouble should step to include the line numbers 
programmatically in the error report.


No a huge priority in the scheme of things, but a "nice to have" sort of

Re: Sorting [was: Polygrid sorting]

So what if you use the column headers on a PolyGrid (or whatever) to 
give the user a UI for sorting by column (adding, or not, sort arrows to 
the header labels).


Is it still more efficient to re-query the database with the new, user 
chosen, sort order and repopulate the PolyGrid?


Or more efficient to just resort the data already populated into the 
grid in the desired order the user has chosen? I suspect this later is 
the more efficient case unless you are sure you have a fast network and 
server with low latency and no competition for bandwidth.


As always, people's use-cases for these widgets vary widely. That is why 
the more versatile a widget is the often (but not always) the better it is.

Combine by column - never used it before, so never thought of it.

It's significantly faster, roughly 40% improvement over the previous 
best.


Note, the spec requires that each line begins with the line number, so 
you need to add something like:



   local tmp
   repeat with i = 1 to the number of lines in g1
  put i  after tmp
   end repeat
   put tmp into x[1]

   put g1 into x[2]
   put g2 into x[3]
   put g3 into x[4]
   put g4 into x[5]

and finish off with

   combine x by column
   put cr after x

to fully match the earlier results.

structure in a single variable to run some procedures on.


So a user driven action of:

1) Add a line (or a few) to the fields
2) repackage data and run a few procedures
3) User repeats starting at step 1

Can become very slow as the number of lines in the fields gets large - 
as you all have noted!


Thank you all again!

Livecode performance problem

2022-08-19 Thread Paul Dupuis via use-livecode

I have a set of fields, call them A, B, C, and D. Each has the same 
number of lines. Each field has different text (per line)


I need to combine the data - frequently - into a form that look like:

C>


For the number of lines in the set of fields. Currently I do this as 
follows:


put empty into vCombined
put fld A into v1
put fld B into v2
put fld C into v3
put fld D into v4
repeat with i=1 to the number of lines in v1
  put i & line i of v1 & line i of v2 & line i of v3 & 
line i of v4 into line i of vCombined

end repeat

I put the field contents into variable before the loop to combine them 
as my understanding is variable access is faster than field access in a loop


My question to the Hivemind is: Is there a noticeably faster way to 
covert these field to the tab delimited structure as show above than the 
code above?


This current takes about 20 seconds for 2000 lines or about a second per 
100 lines (very roughly, I was not using a timer in my code, just my 
wristwatch seconds in the IDE debugger between breakpoints)


Thank you for any pointers in advance,

Paul Dupuis

No list, but I did discover one reason for choosing PolyGrid over 
DataGrid recently. Large number of columns (such as user generated 
research data). The DataGrid is a group and so is limited to a total 
width of all columns of 32767px, or about 327 columns at the default of 
100px per column. Exceed this and the data stops displaying. I have 
tested PolyGrid with 1000 columns without issue. The Datagrid column 
limit can also be an issue if you are close to the limit and the user 
resizes 1 or more columns to exceed the total pixel limit (assuming you 
have column resizing turned on, which it is by default)

This code produces no errors and works. However, I was just trying to 
look up 'effective width' to see exactly what it was doing in the 
Livecode 9.6.8 Dictionary and struck out!


Under the 'effective' entry in the 9.6.8 Dictionary, 'width' is not 
listed as an inherited property that 'effective' can be used with. 
Under 'width' it is not listed. If I look at the entry to the 'stack' 
object, I find 'width' but that just takes me to the entry for 'width'


Am I imagining something, OR is there such a thing as 'effective 
width' and if so, where the heck is it documented?


PS. I thought the width of a stack (or window) vs the effective width 
was teh difference between the inner dimensions of the stack (the card 
size) and the size  of the stack with borders and titlebar (outer 
dimensions). I forget which is which and, again, can not find it 
documented! Also, I thought that contrary to the Dictionary entry to 
the 'effective' keyword, you could SET the 'effective width' of a 
stack/window to change the size of the outer dimensions(?)


I'd appreciate any pointers to where effective width or effective 
height of a stack is documented.


So testing shows that (in LC 9.6.8 at any rate) the following STACK 
properties can use the effective keyword:

height
width
rect (or rectangle)
left
right
top
bottom
topLeft
topRight
bottomLeft
bottomRight

and, indeed, the different between the property and the effective 
property is the property (inside dimensions) and effective property 
(outside dimensions)


The "effective" keyword is ONLY documented with the rect/rectangle 
property in the Dictionary and not for any other dimensional properties, 
even though they work as expected (well except for Window 10: 
https://quality.livecode.com/show_bug.cgi?id=16305)


It also appears (from testing) that you can set the effective rect (as 
documented in the rect Dictionary entry) and set the effective width or 
the effective height (not documented in the Dictionary). I have not yet 
tried setting the "effective" form of the remaining dimensional 
properties (top, left, topLeft, etc.)

You can't use "effective" with custom properties either.
https://quality.livecode.com/show_bug.cgi?id=23557

You *can* set the effective rect of a stack, although you may not get 
the result you expect.

https://quality.livecode.com/show_bug.cgi?id=16305



I now remember bug 16305. Mark entered it based on a list discussion 
where I reported it. Hence my comments on it. I now use Panos's 
workaround (in fact my code base is riddled with "work-arounds"), but 
there seem to be a (limited) consensus that on Windows 10, the effective 
rect should only factor in VISIBLE border elements, not INVISIBLE ones. 
I still wish they would fix it.


That all said, where is effective width/heigh/rect of a stack/window 
documented in the Dictionary? The 'effective rect' and other 'effective' 
dimension properties of a stack/window are important for multiple window 
positioning, resizing, alignment, and more and should be in teh 
Dictionary. ALSO, as the 1 exception to the "you can not SET 'effective' 
things rule, that should definitely be documented.


I'll file a documentation bug report, but I don't want to file one just 
to find out I looked under the 'wrong' place.

Re: Sorting [was: Polygrid sorting]

2022-08-15 Thread Paul Dupuis via use-livecode

Perhaps some expansion of the column "pgContentTypeofColumn" property? 
The current possible values are: 
text|svg-lcname|imagedata|imagefile|color|boolean|autoincrement
Allowing the addition of 'numeric' and 'datetime' would at least allow a 
mapping to sorts although sort support 'international' (perhaps should 
be the default for a polygrid column of type "text" and "binary". I am 
also not sure how svg-iconname, imagedata, imagefile, and color should 
sort. Perhaps svg-iconname should sort as "text". Bolean can sort as 
"text" since ascending puts "false" first and descending puts "true" first.

otherwise sort alphabetical.


Would that be a reasonable enhancement request ?

Would "natural" be a reasonable suggested name ?

From a July 27 comment from Steven Crighton on

For the moment you have to update the new widgets manually. To do 
this, first log in to your LiveCode account. In the left hand 
navigation make your way to Products > thirdparty. Scroll down this 
list to find LiveCode Enhancements and download that bundle. Inside 
the bundle folder there is a widgetpackinstaller.livecode file – If 
you want to update everything in your bundle in one go I recommend 
using that. Simply open that stack and click the install button. Note 
– DataView will now be PolyList after you have updated.


I updated once and looks like I'll have to again.



Thank you Mark! (and Steven)

Re: Polygrid sorting

2022-08-15 Thread Paul Dupuis via use-livecode


FYI,

I also just tested on a MacBook Air, M1, running Monterey with LC9.6.8 
and the version 1.0.0 of the Summer Bundle widget packs and the PolyGrid 
and my sample stack displayed for me at 10, 100, and 500 columns and rows.

I just tested on macOS Mojave (10.14) on an Intel MacBook Pro and the

Now I have to find the MacBook Air with Monterey and see...

So I see that the Summer Bundle of widgets in the store has a note that 
says "Latest update 1.0.19: 11 August 2022"


However, the Download button says "Version 1.0.0". Does anyone know how 
to update the widget set to 1.0.19 or how to update a single widget?

Okay, I built the stack and tested it under Windows 10. The 3 beeps are 
intentional. It is to let me know when it is done as some test with 500+ 
columns/rows takes a while. It does display under LC9.6.8 (64 bit) on 
Windows 10.


Now I have to go try it on macOS?

Re: Polygrid sorting (problems)

2022-08-15 Thread Paul Dupuis via use-livecode

So there is an example of sorting in the PolyGrid documentation under 
the entry for the MESSAGE "headerClick" and under the entry to the 
PROPERTY "text" (and in 'the text of me')


The example code only sort the visible rows as "the text of widget X" 
returns the data of PolyGrid X as tab delimited, WITHOUT the column 
headers, but ONLY the visible rows.


So, what to use for sorting all the data in a PolyGrid by a particular 
column?


The tsvData of widget X (and csvData, and Text) doesn't seem to work. 
The all seems to only get the visible data (rows). Only the pgData of 
widget return the whole dataset of the PolyGrid. Is this the way these 
properties are supposed to work?


If that is how text, csvData, and tsvData are supposed to work 
(returning only the visible rows), then the sort example in the PolyGrid 
documentation require updating otherwise these properties require updating!

Datagrid and new Summer Bundle table/grid widgets

2022-08-11 Thread Paul Dupuis via use-livecode


To anyone with the Summer Bundle:

The Datagrid object has a practical limit on the number of columns that 
I just reported as https://quality.livecode.com/show_bug.cgi?id=23875
(about 327 columns at a default column width of 100px due to the Group 
objects 32767px width limit)


Do any of the table/grid widgets in the Summer Bundle allow going beyond 
this limit? Could someone with a Summer Bundle please test the 
table/grid widgets. I have included the script I populate the column 
names and a first row of data in a Datagrid with below. I'd just like to 
know whether any of the new table widgets can exceed thsi Datagrid 
limit. Thank you to anyone who can spare the time to test in advance.


on mouseUp pMouseButton
  local tColumnNames, tArray
  ask "Number of columns?"
  if it is empty then exit mouseUp
  --
  repeat with i=1 to it
    set cursor to busy
    put "Column"& into tColumnName
    put tColumnName into line i of tColumnNames
    put i into tArray[1][tColumnName]
  end repeat

Re: Datagrid internal error

On 8/10/2022 5:02 PM, Trevor DeVore via use-livecode wrote:

32,767 is the max for width as well. If there are enough columns it is
possible that the DataGrid is rendering a group that exceeds this limit and
hence the error. The DataGrid works around the limit when rendering rows,
but not when rendering columns.

I suppose a quick test would be to create a DataGrid with 330 columns that
are at least 100 pixels wide and see if you get the same error.



So I created 2 test stacks with a Datagrid and a button to set the 
number of columns and populate a row of data. One stack I did in 
Livecode 4.6.4 (the oldest I have) and one I built in Livecode 9.6.8 to 
see if there were differences in the handling of the error condition 
between versions of the Datagrid object.


[Note: Some of the Datagrids in our app are from LC 4.6.4 and we've 
never removed them and replaced them with newer versions and I don't 
believe Livecode does anything to automatically update the Datagrid 
objects in an old stack when opened in a new version of Livecode]


Under LC464, trying to create a number of columns with default widths 
that would exceed the 32,767 pixel width limit of the group object 
(using 330 columns with a default width of 100px or 33,000 pixels) produces:


1) A blank header (no columns)
2) Visible column for data, where only the visible columns of the first 
row (8 columns) are populated with data and when you scroll to the 
right, all remaining column of the 1st row of data are empty. The grid 
is scrollable horizontally to what looks to be around 320-330 columns.


Using 320 columns, works as expected. 325 works; 327 works. 328 only 
produces 327 columns in the header with 327 values for data in the first 
row. 329 produces a header with 329 columns and no data is rendered in 
the 1st row.


Under LC968, the LC968 test version of this with 330 columns produces:

1) Columns headers 1 to 8 (the header that are the visible width of the 
Datagrid)

2) No data is rendered and the grid is not scrollable.

Using 320 columns, works as expected. 325 works. 327 works. 328 produces 
327 columns in the header and no data in the first row. 329 is the same 
as 330 (only 8 visible column headers and no data and no scrolling).


So, the results are subtly different from Datagrids from LC4.6.4 and 
Datagrids from LC9.6.8, but both fail to do what a user would expect 
without any visible errors.


However, having the number of columns exceed the width of a Livecode 
group object in pixels does not seem to be the source of the error I am 
trying to track down which was:


Line 139 set the dgProp["columns"] of grp "rwMatrixObj_DataGrid" to 
tColumnNames


tColumnNames is a variable containing a list of text lines that are 
customer entered column names, so they could be ANYTHING (up to 255 
chars, no control characters, including DEL (127)) that a user could 
type or paste into a field, including words in any language using Unicode.


As the executionContexts data does not contain the actual values of the 
variable tColumnNames when the error occurs AND (for reasons) I can not 
get the data from the customer, does ANYONE have any idea what 
tColumnNames might contain that could produce the error(s) show below?

Re: Datagrid internal error

2022-08-10 Thread Paul Dupuis via use-livecode

I do appreciate the responses. My question was not about the number of 
records, but about the number of COLUMNS and whether there is any 
practical or known limit.


When my code is setting the column names, that list comes from customer 
entered data. I know that each name is less than 255 characters and 
restricts entry of certain characters (previously listed) such as comma, 
[ ], etc. How many names is unknown.


In this specific case of the error I reported, the customer is not in a 
position to be able to help much (if at all). Since it is customer data 
dependent, we are not able to reproduce the error in the IDE. SO my very 
specific questions was: Has any one seen an error like the one I 
reported (copied again below) OR know of any issues/limits when setting 
the dgProp["columns"] property of a Datagrid?


A customer encountered the following execution error (below) in our app 
(built on Livecode 9.6.7, MacOS 12.5). This error is occurring in the 
scripts for the Datagrid itself, rather than our code. At the end, it is 
one of our handler, "populateMe", where line 139 is where the error starts.


Line 139 set the dgProp["columns"] of grp "rwMatrixObj_DataGrid" to 
tColumnNames


tColumnNames is a variable containing a list of text lines that are 
customer entered column names, so they could be ANYTHING (up to 255

I was referring to dgNumberOfRecords

• get the dgNumberOfRecords
• set the dgNumberOfRecords of group "DataGrid" to 20
• Getting the dgNumberOfRecords is the same as getting the 
dgNumberOfLines. Setting the dgNumberOfRecords has a special significance 
however. If you set the dgNumberOfRecords then you are telling the data grid 
that you know how many total records there are and you are going to supply the 
data for each record on an as-needed basis. This is useful when you have data 
in a database cursor that you would like to feed into the data grid.
After setting this property the data grid will send the GetDataForLine message 
to the data grid whenever it needs to display data for a particular line. You 
can define this command in the data grid script or elsewhere in the hierarchy. 
The definition is as follows:

command GetDataForLine pLine, @pDataA
   
end GetDataForLine


You should fill pDataA with the appropriate data based on the line of data 
being requested. pDataA should not have a numeric index. It is the array that 
would be assigned to one of the numeric indexes if you were assigning the 
dgData property.

Summer Bundle table/grid widgets....

2022-08-09 Thread Paul Dupuis via use-livecode

I am in need of a control to display a table of numbers. The top ROW are 
column labels (text, sometimes up to 255 characters). The left COLUMN is 
row labels (text, sometime up to 255 characters). I'd like a widget that:
1) Can display this with the top row (or headers) fixed so they remain 
visible when the data is scrolled
2) Can display this with the left column fixed to they remain visible 
when the data is scrolled
3) Provides built in abilities to sort the numbers in all the data of 
the grid/table, by any column, ascending or descending as the user desires.


I have already built this with a grouped field (for the fixed left 
column) and Datagrid (for the remained of the table).


Do any of the new widgets in the Summer Bundle do this inherently 
without me having to make a custom object (as I had to do with the field 
+ Datagrid)?

Re: Datagrid internal error

2022-08-09 Thread Paul Dupuis via use-livecode

comma delimited or cr delimited, without looking it up, I am sure it is 
in the right format since it work 99.99% of the time.


The names that would be in the column list all go through a name check 
function. That function prevents names that are all spaces, longer than 
255 characters, or are a handful of "reserved words" and checks that 
each name does not contain the following characters


    if (it < 32)  then return false -- all control characters (0x 
to 0x0031)
    if (it = 34)  then return false -- "    quote (0x0034) 
-- LC string encapsulator
    if (it = 40)  then return false -- ( left parenthesis (0x0040) 
-- used in filter and theory criteria
    if (it = 41)  then return false -- )    right parenthesis (0x0041) 
-- used in filter and theory criteria
    if (it = 44)  then return false -- ,    comma (0x0044) 
-- LC item delimiter
    if (it = 60)  then return false -- <   less than sign (0x0060) 
-- htmlText tag delimiter
    if (it = 62)  then return false -- >    greater than sign (0x0062) 
-- htmlText tag delimiter
    if (it = 91)  then return false -- [  left square bracket (0x0091) 
-- LC merge delimiter
    if (it = 92)  then return false -- \    backslash (0x0092) 
-- regex string escape character
    if (it = 93)  then return false -- ] right square bracket (0x0093) 
-- LC merge delimiter
    if (it = 124) then return false -- | vertical bar (0x0124) 
-- used in code

    if (it = 127) then return false -- DEL delete (0x0127)

So, comma's are excluded, as are [ and ], and control characters, etc.. 
However all Unicode characters, codepoints 128 and up are allowed. 
Testing shows you can have a Datagrid where you can set the columns to 
empty, so that is not the cause of the error.


I can only image that the customer entered a name with some characters 
that Datagrid has a problem with as a column name OR that the shear 
number of columns (as the customer is working with a very large dataset) 
exceeds some practical Datagrid limit, but what would that be?


I don't really want to have to carve out time to build test stacks to 
try names with every possible characters or ever increasing numbers of 
column names until the error occurs or those possibilities are ruled 
out. I was hoping there might be someone on the list who was familiar 
enough with the internals of the Datagrid to have some idea what might 
have caused the error.


Unfortunately, the customer's data is confidential, so they do not want 
to provide the data to us to use for testing. And the customer is either 
not technically savvy or does not have time (they have said they are 
under a deadline) to help much in troubleshooting. They can get the 
analysis this Datagrid provides by exporting some data to Excel and 
doing the analysis in Excel, so the error is not a show-stopper for them 
as well. Definitely not as convenient as the report in our app, but a 
viable work-around.


See my original post for the executionContexts and the specific error.

For example, some information from the customer suggest they are working

Datagrid internal error

2022-08-08 Thread Paul Dupuis via use-livecode

A customer encountered the following execution error (below) in our app

tColumnNames is a variable containing a list of text lines that are 
customer entered column names, so they could be ANYTHING (up to 255 
chars, no control characters, including DEL (127)) that a user could 
type or paste into a field, including words in any language using Unicode.

I think the widgets are great additions to Livecode. That said, I have 
not purchased the MegaBundle. My Livecode commercial/business/whatever 
license is paid out to something like 2023 or 2024 due to past fund 
raising where the mothership offered license extensions as part of the 
packages in those efforts. I am licensed for all platforms, with the 
professional extensions, so I don't need any more platforms and I really 
don't need my license extended or any store credits. If there had been a 
bundle offering that was JUST the extra widgets and stuff without an LC 
license stuff bundled in, I would have bought one.


I don't like to get too far ahead of LC licensing. After all I could get 
hit by the proverbial bus tomorrow and having 2 years or prepaid LC 
licensing would go to waste (for me at least).


So, I think it is worth the $ if you need additional platforms and/or 
your license extended (if it is about to expire in, say, another 15 
months or less). It may not be worth the $ if you are all set for the 
next couple of years on LC licensing itself.

Re: wait 0 with messages (and the defaultStack)

Yea, a number of years ago, I went to always fully qualifying object 
references through all the techniques you mentioned, but we've just not 
had a chance to scrub the entire code base (100,000 lines+) and so this 
one got missed until now.


We're now going through the entire code base to catch any last cases 
where object references could be in error due to any wait with messages 
statements (combined with user actions).

command or function that is not in the message path.

For instance, if I am processing all the fields on a card, I put the handler in the card script 
and then use the form 'field "myField" of me' to reference each field. Even better, 
if I reference the object repeatedly I will 'put the long id of  of me'

On 7/30/2022 3:53 PM, Paul Dupuis via use-livecode wrote:
My understanding of 'wait 0 with messages' is that it will cause any

Is this correct?



First, than you to those that have responded.

The reason I got curious about 'wait 0 with messages' (or even just 
'wait 0') is because of an epiphany I had just last week regarding a bug 
a customer reported in our software. The customer experienced and 
execution error and our software presents a custom dialog that allows 
them to email out support account some information, including the 
'executionContexts' so we have some code debugging information.


The problem as a 'can't find object' error. In reviewing the code, I 
could see no way that the error should have occurred. The code was using 
the ChartMaker library to create a graph. It all looked good per 
documentation and we could not reproduce the error in house. I then 
noticed a 'wait 0 with messages' prior to the line the error occurred on 
and noticed that the line that had the error used object references 
relative to the current stack (which the defaultStack was explicitly set 
to much prior).


My epiphany was realizing - for the first time, despite LiveCodeing 
since HyperCard and having a Masters in Computer Science and my entire 
career being in the IT/software development space for over 40 years - 
that when the 'wait 0 with messages' is executed, if there was a pending 
USER click on another window, the defaultStack could change and then the 
relative object references would not be able to find their target objects.


Perhaps I should have realized that a 'wait 0 with messages' COULD 
result in the defaultStack changing much sooner OR perhaps I should 
always fully qualify all object references (which I have been doing for 
quite a few years, but this was old code), but it is a 'gotcha' of using 
wait with messages I had never thought of.


The Dictionary Entry (LC 9.6.8) does state "If the wait..with messages 
form is used, LiveCode continues normal processing during the wait. The 
current handler is frozen, but the user can start other handlers and 
perform other actions such as switching cards." and 'switching cards' 
does imply changing the context of relative object references even if 
the defaultStack does not change, so perhaps I should have realized, but 
didn't until just last week.


Now I am very curious about exactly what wait 0 with messages does and 
also about what actions change the defaultStack. Does anyone know of an 
article or something someone has done to identify all the messages, 
commands, or functions that change (or potentially change) the defaultStack?

Is this correct?


My understanding of this is close but not quite the same.
The "wait 0 with messages" statement is the fastest implementation 
("wait 0") of an opportunity for the system event loop to process any 
pending instructions. The "with messages" statement in effect yields 
control to the event loop to check if any "send in time" messages have 
timed out and are pending or to handle other tasks that may have 
accumulated (mouse or keyboard events, etc).




So Mark,

Your understanding is that 'wait 0' (WITHOUT with messages) would allow 
OS events like a screen redraw, USB drive insertion/removal, etc. but 
NOT livecode engine events in the queue like mouseDown, mouseUp, 
resumeStack, etc,


OR

That wait 0 (again without with messages) would include in addition to 
OS events, LC built-in events like mouseDown, resumeStack, etc., but not 
custom messages (or LC standard messages) sent to the queue via sent in 
time?


Thanks for responding!

Re: Livecode Builder developer wanted

I've hired and managed independent software developers for various 
businesses for nearly 40 years. I am well aware of the market.


We pay competitive contract rates. My estimate of time is probably about 
right for someone who has set up at least 1 or 2 cross-platform LCB DLL 
wrappers based on decades of estimating IT projects, but it was more 
meant to suggest the work is something in the scope of many hours to 
days vs. weeks or months.


As for job size, if you are a contract developer who has a queue of 
large jobs providing regular income, good for you. My experience is that 
many contract developers value non-time sensitive small jobs they can 
fit in and around larger projects to fill in the inevitable gaps between 
larger projects that can come up.


If no one is available or interested, as I said, it is not time 
sensitive, so we can either wait or tackle it ourselves as time permits.

Hi Paul,

I seriously doubt that anyone would be chomping at the bit for this task.

First, you expect the person to spend their free time looking at the task to
determine the effort and cost required to accomplish the task.  There is
no paid incentive to do that first step.  If after the person gave you their
estimate, and you decided you didn’t like it, then the developer has lost
their time and effort for nothing.

Secondly you have stated that you expect the effort required would be
no more than 1 day.  It’s very possible that your 1 day projection is
completely off the mark. If it took the person more time than that, you
would probably be dissatisfied.  Who would want to deal with that?

Thirdly, even if your projection of 1 day of effort was 100% correct, why would
anyone want to bother trying to do the task for just one day’s pay?  It simply
isn’t worth the time or the hassle for any potential programmer to want to
deal with the task for that reason alone.

So yes, the bottom line here for you is that you indeed will have to work
on the task yourself or it’s not going to get done at all.

I hope you will keep this in mind for any future work you would like
to have performed.

I have to get back to my work here.

I hope you have a fruitful and productive day!

Actually, I am surprised. I have seen mentioned on this list dozens of

However, if there are no takers, then I guess I'll just make the time

macOS Ventura (13.x.x)...

2022-07-10 Thread Paul Dupuis via use-livecode

Is anyone out there in Livecode land running a developer beta of macOS 
Ventura (13.x.x)?


If so, I am hoping you can perform a quick test:

systemVersion() returns 10.16 for macOS Big Sur or Monterey under 
Livecode 9.6.7 and earlier (in the 9.6.x versions). The systemVersion() 
bug was just fixed in LC 9.6.8.


I'd like to ask if someone on Ventura (13.x.x) can run LC 9.6.7 or any 
9.6.x less than 9.6.8) and confirm that systemVersion() also reports

Images and arrays...

2022-07-05 Thread Paul Dupuis via use-livecode


I am drawing a blank:

If I have the following code:

  export snapshot from rect tRect of player 
"mediaConvert" of stack "libHrAPI" to tImage as PNG

  put tImage into pRefArray[tRef]

The actual image (not a reference, such as a long ID) is placed in the 
tRefArray[tRef] array element


However, if I have a variable tImageID that contains a reference to an 
image such as


image id 10328 of card id 10001 of stack "X"

How do I get that actual Image stored in the array?

put tImageID into pRefArray[tRef] -- results in the array element 
storing the long ID


put (tImageID) into pRefArray[tRef] -- also results in the array element 
storing the long ID. I thought the () might for the long ID to be 
evaluated to an actual image

The results of the testing would me help to enhance my LC Notarizing lesson.

Re: {OT} Are there any ffmpeg "experts" on this list?

2022-06-24 Thread Paul Dupuis via use-livecode


Panos,

Thank you!

I was unaware of the mediaFoundation library - I had thought that we'd 
not see support under LiveCode 10 switches from DirectShow to 
MediaFoundation.


That said, our application is macOS and Windows and the appeal of ffmpeg 
via shell is that the same code will work across platforms for us.


Still, for other projects, I'm very happy to have been made aware of the 
mediaFoundation library!

Not a ffmpeg expert, but have you seen the mediaFoundation library? See the

Re: Would anyone miss convertOctals?

2022-06-09 Thread Paul Dupuis via use-livecode

Never use octal. pretty much any entries theses days are decimal or 
hexadecimal. Even binary (bit shifting or masks) is exceedingly rare



On 6/9/2022 8:44 AM, Mark Waddingham via use-livecode wrote:
So I'm currently sitting here about to embark on fixing 
 (which is the 
final thing to sort out before being able to merge my constant 
expression patch) and I was reminded of 'convertOctals'.


Now, generally, I am somewhat averse to actually removing any language 
feature (even those we have deprecated, unless we absolutely have to!) 
- however, I would really like to make convertOctals have no effect at 
all in 10.0+ as it adds a disproportionate amount of complexity 
compared to (what I think, at least) its utility is (particularly in 
the context of things 'coming next' like the script compiler).


So three questions:

  1) Do you know what convertOctals is, and what it does?

  2) If you do, have you ever actually used it in any scripts which 
are actually still in use?


  3) If you do use it in any scripts which are still in use, would you 
be willing to change them to not use it?


  4) If you do use/have used it, had you ever noticed that it has been 
slightly broken for years?


Now, its always better to offer a carrot when there is a stick (or in 
this case, an axe) being wielded and the carrot in this case would be 
to expand the numeric literal syntax to add both explicit octal and 
binary number literals alongside hexadecimal:


    0xabcdef - hex literal
    0o777 - octal literal
    0b101110101

The key difference between 0o777 and using 0777 (with convertOctals 
true) is that the former is not ambiguous at parse time, it doesn't 
require a runtime property set to true in order for the engine to 
convert the string to a number correctly.


Please let me know your thoughts :)

Warmest Regards,

Mark.

P.S. In the scheme of 'breaking changes' - we've already made a number 
of them for 10 already, and my gut tells me removing convertOctals is 
likely to cause less consternation than those we already have - but I 
could be wrong!

Re: Maximum length of mySQL request ?

2022-05-20 Thread Paul Dupuis via use-livecode


You can save some characters by the following:

SELECT ... FROM myTable WHERE id IN (5523,7831,162814,34895,...)

which is the same as using multiple OR equals in your example.

If you need to break this up further, you can UNION the results of 
multiple queries, such as:


SELECT ... FROM myTable WHERE id IN (5523,7831,162814,34895,...) -- i.e. 
the first 100 or 1000 ids

UNION
SELECT ... FROM myTable WHERE id IN (100,512,,16545,...) -- the next 
100 or 1000 ids

UNION
... repeat as needed

Hi list,

I don't mean the results returned by mySQL, but the request itself.

For instance, I have a table with 18 entries and counting, and
I will need to send requests such as :
SELECT FROM myTable WHERE id = 5523 OR id = 7831 OR id = 162814 OR id 
= 34895...

and at times the request might concern 100 ids or even more.

I am not too concerned about execution speed, as id is a unique key,
but rather for the request itself : I wonder if it might be truncated
if too long...
Or perhaps a better and safer practice would be to break it into a 
serie of

shorter successive requests when it exceeds a certain threshold ?

Thank you in advance.

In older versions of LC you could have custom property keys that had 
commas in them, such as a key like "topic,subtopic" for a online help 
system. The current (and recent) property inspect tries to convert 
custom property keys with a comma into arrays! Just thought I would

This is not any sort of immediate help, but a quick Google search 
suggests that both AVF (Apple Video Foundation) and MMF (Microsoft Media

support classes and APIs to access multiple media tracks and metadata. I 
don't know about Mobil player support (or Linux), but now is the time 
while Livecode 10 is in developer preview stages to lobby Livecode Ltd 
to broaden the player object to support more cross-platform features. I 
suggest opening an enhancement request at https://quality.livecode.com/ 
for text track access (subtitles are an accessibility requirement on 
lots of media these days) for LC 10.

Bob Sneidar wrote:

Where are we supposed to write application support files if not to 
Application Support?

First they demanded control of the file format apps use for Prefs, now 
this...

I did a little bit of research when I ran into my app breaking on 
Catalina and up when trying to reach a folder at 
specialFolderPath("temporary") and write files in that folder. The 
problem is that newer macOSes use an runtime algorithm to try to 
determine when an application is asking for access in "special" places. 
If the algorithm detect special access (sat to the Desktop or Documents 
folder or a Webcam and so on) the OS pops up the "Do you want to allow 
.. " dialog for the user to allow or deny access. An application signed 
and notarized WITH entitlements can specify some entitlements that are 
checked and if the App has declared these entitlements to protected 
resources, they are allowed. Some "protected" resources have NOT 
corresponding entitlements (at least currently). For disk access to 
folder paths without entitlements, the user can grant an application 
Full Disk Access, from System Preferences > Security, but and App can 
not specify an entitlement for Full Disk Access. It must be granted by 
the user.

Further, an Apple Engineer is a forum response (or someone claiming to 
be an Apple Engineer) noted that the algorithm to detect requests for 
special access resources can make mistakes and not recognize a request 
as a request and there for present a dialog to the user for allowing or 
denying and the default is to deny. So some circumstances, like apps 
running  in multiple processes (was an example cited, but it was implied 
there are other circumstances) your app MIGHT get the allow/deny dialog 
OR it might not - depending on your app. And for some resources, it just 
won't get any dialog and no entitlement will allow access, only 
instructions to the user to grant Full Disk Access (or some other 
similar ONLY allowed by the user permissions) will work.

In short, Apple's sandboxing is a developer mess. If you can, placing 
files in the Documents folder is best as (A) you can specify the 
Documents folder in an entitlement and (C) the sandboxing algorithm does 
seem to always detect (first time) Documents access requests and pop up 
the dialog.

DISCLAIMER: I did not have time to research this in detail and the 
"apple engineer" may or may not have been a real Apple engineer or knew 
what they were posting about. Our installer asks people on the last 
screen to grant our apps full disk access (if they are on Catalina+) and 
most people do and it solved a lot of recoding.

No. Alt+A9 does not work. I checked my Registry (per

I thought I would be clever and write a bit of LC script (see below)

I guess the larger question is: For a person developing an LC based app 
who's users what to enter Unicode characters, what is the "best

Well, Microsoft is not consistent (not that I am surprised!)

ALT X number works in TextPAd, but not in MS-Word. The alternate method 
(mention in this MS support note: 
https://support.microsoft.com/en-us/office/insert-ascii-or-unicode-latin-based-symbols-and-characters-d13f58d3-7bcb-44a7-a4d5-972ee12e50e0) 
of type U+ such as U+B5 for µ and then pressing ALT-X does work 
in MS-Word, but not in TextPad!


Neither method works in Livecode 9.6.7
So, not:
ALT + 00A9
ALT 00A9
ALT X 00A9
U+A9 ALT X

Hi list,
I have been asked by a client to make some upgrades to a standalone 
app that I built with LC 6.5 about 12 years ago.
The app is a front end for managing a remote DB on a server. The DB 
content is roughly 90% in french, and the rest in english and german. 
It has about 16 entries and counting.


I am about to buy a LC standard plan for both Mac and Win, since the 
app is been used on both platforms, and will also be in the future.
But before I proceed, I'd like to make sure that it will help solving 
a minor problem that users have met lately.


Last year a re-compiled the app, without changing anything, with a LC 
8.2 Community version.
It keeps running fine on both Win & Mac, except that on Windows, some 
special characters in french (like Ê or Æ or Œ) have become impossible 
to type with regular keys combinations (or any other mean), when it 
was possible before with the LC 6.5 version.
Furthermore, a few new users will be added to the crew, who will work 
with qwerty keyboards, when the rest of the staff will continue to 
work with azerty keyboards.


So finally my question : it seems that the standard plan is the best 
option because it will give me access to the latest LC versions, but 
what about these special characters issue ? Is it only related to LC 
8.2, or will it also occur with the latest versions ?


Thanks in advance.

Re: Launch of multiple application instances (Mac vs Win)

2022-05-08 Thread Paul Dupuis via use-livecode

Nevermind. I found the "Relaunch Sampler.rev" stack referred to in the 
Dictionary entry and it explains how the message is used further.



On 5/8/2022 12:08 PM, Paul Dupuis via use-livecode wrote:

The LC 9.6.7 Dictionary entry to 'relaunch" states:

3. If nothing is returned but the message is not passed, then the new 
instance is terminated and the existing instance's "defaultStack" is

If there are no existing instances, the new instance will run.

1. seems pretty straightforward:

on relaunch

Would allow the 2nd (or whatever number) instance to continue to start up


3. Seems obvious as well:

Here, the message is not passed, so the new instance is terminated and 
the "defaultStack" of the existing instance is brought to the foreground



However, I do not understand 2. What the heck does ;If "background" is

only example given is:


onrelaunch pDocument openDocument pDocument endrelaunch

And the Dictionary states that actually multiple parameters can be 
passed (for example if multiple documents where dragged onto the app 
to launch it). I feel there is something missing in the Dictionary entry!

Launch of multiple application instances (Mac vs Win)

2022-05-08 Thread Paul Dupuis via use-livecode


Seeking help:

On MacOS when you try to launch a second instance of an application, the 
macOS just brings the open app to the front (for example, if it is 
hidden on minimized).


On Windows, when you try to launch a second instance of an application, 
Windows launches a second (or 3rd or 4th or ...) instance of the 
application.


All well and good, but here is my problem. We have some users of our 
application that, on Windows, are accidentally launching more than once 
instance of our application and then getting confused (our users are 
often not very computer literate).. This confusion can lead to them 
thinking they have lost data or other problems caused by doing some work 
in one instance and some in another and not recognizing they have 
multiple instances running.


I would like to add some start up code to application, that on Windows, 
detects if our app is already running and  (a) shuts the 2nd instance 
down OR (b) [PREFERABLY] warns the user they are launching a second 
instance and offers to (1) bring the existing instance to the foreground 
(and shut itself down) or actually continue and launch a seconds 
instance (for power users who know what they are doing)


Has anyone written code to do this?

i.e. code to detect an already running instance and code to bring that 
instance to the foreground?


If so, are you willing to share the code?

Just looking to not have to reinvent the wheel here.

Thank you in advance!

Re: LC 9.6.7 export snapshot from a player object seems to fail on Windows (10)

2022-04-29 Thread Paul Dupuis via use-livecode

There are apparently no work-arounds for the failure of this version of 
the export snapshot on Windows 10/11


I've tried:
    -- method that does not work on Windows, but works on macOS with 
player hidden [A REQUIREMENT]

    put the rect of player "myPlayer" into tRect
    export snapshot from rect tRect of player "myPlayer" to tImage as PNG
    put tImage into img "myImage"

    -- trying alt method #1 [FAILS LIKE ABOVE]
    export snapshot from player "myPlayer" to tImage as PNG
    put tImage into img "myImage"

    -- trying alt method #2 [TAKES A SNAPSHOT OF THE WINDOWS SCREEN]
    put the rect of player "myPlayer" into tRect
    export snapshot from rect tRect to tImage as PNG
    put tImage into img "myImage"

    -- trying alt method #3 [WORKS ONLY IF VISIBLE ON SCREEN WITH 
NOTHING ON TOP (no overlapping windows)] This also fails (with an 
execution error) if the user has moved the window so the player is 
off-screen!

    put the rect of player "myPlayer" into tRect
    export snapshot from rect tRect of window (the windowID of this 
stack) to tImage as PNG

    put tImage into img "myImage"

As I need to grab multiple specific frames of video as a series of 
images behind the scenes for any analysis/report, I can not have the 
player visible while the user is running the analysis. Current the code 
hides the player controller. The player is on a non-visible stack and 
the video is associated with that hidden player. A loop then sets the 
currentTime of the player to various points based on clips provided by 
the researcher and takes an image of each frame that currentTime is set to.


This works on macOS and in some prior versions of LC and/or Windows, 
worked on Windows as well and now in LC 9.6.7 on WIn 10/11 it does not.

Prior to the export the player has a video load and has the 
currentTime set to a particular frame, and I can see in the stack that 
the player is showing the correct frame is visible.

I can also see that the image "imageConvert" is also visible, but empty

After the Export Snapshot is executed, it looks like tImage contains 
valid PNG data, although I can not tell if it is the correct image
After the Put statement, the image "imageConvert" is set to a white 
rectangle with a little bit of the player border on the left and top. 
It is the same size as the player where as the empty image I started 
with was larger.


This is with LC 9.6.7 on Windows 10. This code works on macOS. Does 
anyone know if there is a known Windows bug with export a snapshot 
form a player and any work around?

Hi Paul

I just tried the same thing and got the same result.  It works on Mac, not on 
Windows.

I also tried exporting the image as a file to see if that made any difference.

   export snapshot from rect tRect of player "mediaConvert" of stack 
"libHrAPI" to file [filepath/filename.png] as PNG

  I got an image file but it is the same as what you see in the image object on 
the stack — an image of a white rect inside the player boarder.

So it looks like it is a bug.  The snapshot does create a proper png it just 
doesn’t grab the current video image inside the player it just gets a white 
rect.

On 4/28/2022 11:12 AM, Mike Kerner via use-livecode wrote:

I did, but I was hoping for some community comment, as well.


Here is my take on the content I was interested in:

1) Web application development. If you are building a new app for the 
web, you can do that pretty well now in LC 9.6.7 and LC 10 will be even 
better.


2) If you have an existing application, say for the Desktop, but also 
for Mobile, depending upon what that app does, porting it to the web 
under LC 9.6.7 can run into problems, under LC 10 it will be easier, but 
10 still has a lot of "developer preview (dp) releases to go before all 
the things that will make web apps under 10 better will be there.


3) The compiler will be a nice addition for most people, an *essential* 
addition if you have some app that is currently performance constrained. 
The compiler is off in the LC 10 (release) and LC 11 time frame.


4) In Kevin keynote he alluded to some possible language/object 
enhancements t o make responsive UI design easier (less coding). These 
may (or may not) include such things as a "group type" object to layout 
panes or rows and columns  for interface elements (other LC objects) and 
- as part of another topic - a new single window IDE design may have 
dockable and undockable windows that may or may not have code support 
that developers can use to make having their own dockable/undockable 
windows built more easily. Some of this work will be a replacement for 
the Geometry Manager (little used due to problems with it)


So, for me, a number of things I am keenly interested in: (1) easier 
posting of existing desktop apps to the web, (2) faster apps, and (3) 
language enhancements that may UI design faster and involves less 
coding. However none of this is available now and it will be arriving 
over various time frames from "soon" to "later".


All comments and interpretations of what was presented are my own.

Prior to the export the player has a video load and has the currentTime 
set to a particular frame, and I can see in the stack that the player is 
showing the correct frame is visible.

I can also see that the image "imageConvert" is also visible, but empty

After the Export Snapshot is executed, it looks like tImage contains 
valid PNG data, although I can not tell if it is the correct image
After the Put statement, the image "imageConvert" is set to a white 
rectangle with a little bit of the player border on the left and top. It 
is the same size as the player where as the empty image I started with 
was larger.


This is with LC 9.6.7 on Windows 10. This code works on macOS. Does 
anyone know if there is a known Windows bug with export a snapshot form 
a player and any work around?

I would REALLY like language support for easier layouts, from groups (or

resizable groups or controls. The geometry manager is not idea and

Well, if the language isn't updated to support dockable windows then 
that sucks! I've coded dockable windows in LC script currently. Each of 
2 Windows has a group that contains all the relevant functions of the 
windows. One window has a dock/undock control outside it's groups. 
Docking moves the groups to the 1st window and remove the window so now 
the 1st window contains the 2 functional groups next to one another. The 
groups that was just docked has an undock control. Clicking it move that 
group back to it's own window which appears and is sized appropriately 
and the 1st window is resized for just the single group.


It is a pain to script and it would make single vs multiple window 
layout management much easier if it was built into the language in some way.

Re: Curved text possible?

2022-04-27 Thread Paul Dupuis via use-livecode


There is not a native way to do this in LiveCode.

An approach might be to use the shell() function (see Dictionary) to 
pass the text to some external graphics utility that renders and image 
of it curved and then import the image back into Livecode. There may be 
other work-arounds.

I didn't have a chance to ask follow up questions, but I recall Kevin 
saying they were headed towards "dockable windows", presumably meaning 
that all (or many) of the parts of the IDE can be docked into a single 
window view or undocked to separate windows (for example for people with 
multiple monitors doing desktop development. I have no idea if that 
includes the Script Editor, but I might expect that it would.

Some parts of having such a thing, as opposed to a sea of separate palettes,

But one aspect would prevent me from EVER upgrading to v10, and that is if the

in fact planned?

The equivalent new functions for numToChar and charToNum is 
numToNativeChar and nativeCharToNum. Those return the same values as 
the originals. However, I'm still getting the wrong result. I can 
subtract 94 to get lower-case "f" but that isn't consistent; the 
amount to subtract varies depending on the value of pKeyName. So 
there's some trick I'm missing.


Tested on Mac.



Thank you for verifying macOS!

I did not know about numToNativeChar and nativeCharToNum so thanks for 
that also. However, after looking at a decimal table of MacRoman, the 
suggested formula to remove the "high-bit" in the Dictionary will NEVER 
work no matter what functions are used. The high-ASCII characters of 
MAcROman (bytes 128 to 255) do not correspond to any alphabetical range. 
In other words, the numerical equivalent of OPTION-A through OPTION-Z is 
not in sequential order.


You would either have to code it as:

on optionDownKey pKey
  if platform() = "MacOS" then
    if pKey = "ƒ" then put "f" in tKey -- MacRoman byte 196 (OPTION-F 
is pressed)
    if pKey = "≈" then put "x" in tKey -- MacRoman byte 197 (is NOT 
OPTION-G (expected if in alphabetical order and you could just do math 
to get the ASCII key character), but is OPTION-X)


In my opinion, this makes the optionKeyDown handler on macOS next to 
useless and it is far more intuitive from a develop and code 
documentation perspective if the letter of the key pressed in 
conjunction with the OPTOPN key was returned.


And, of course, you can work around this with a rawKeyDown or rawKeyUp 
handler, but I would consider the state of optionKeyDown on macOS defective.

Yes, there are work-arounds. My post was about confirming the bug so I 
can report it to Livecode.


In this case, we have a shipping application in which the optionKeyDown

broken.


If everyone just codes work-arounds and bugs are never reported, then 
the bugs will never get fixed.


Sorry, a long frustrating day.

optionKeyDown message broken

2022-04-21 Thread Paul Dupuis via use-livecode

I am finding problems with the optionKeyDown handler on both Windows 
(where it's the ALT key) and macOS (OPTION key). This is in Livecode 
9.6.7 STABLE under macOS Mojave and Windows 10


In a new stack, place the following in the card script:

on optionKeyDown pKeyName
  if platform() = "MacOS" then
    put numToChar(charToNum(pKeyName)-128) into tKey1 -- original 
sample from Dictionary
    put numToCodePoint(codepointToNum(pKeyName)-128) into tKey2 -- 
trying using non-deprecated functions

    answer pKeyName,tKey1,tKey2
  else -- windows
    answer pKeyName
  end if
end optionKeyDown

On macOS, the LC 9.6.7 Dictionary shows the need to strip the "high" bit 
off the character to get the letter of the key pressed, for example, 
OPTION-F produces ƒ

The above script on macOS produces for OPTION-F the following ƒ, D, Ë
Where as what you want for either tKey1 or tKey2 to be "F" the key 
pressed with OPTION-F


I think this is a case where the Dictionary entry for optionKeyDown (for 
macOS) needs to be updated with a formula that works since LC was 
updated to Unicode with version 7 "High" ASCII macOS characters are now 
UNicode and not the same character codes.


But Wait. Windows is even worse

This code on Windows does not produce a letter of any sort. It produces  
As soon as you press the ALT key, before you can even press ALT-F, this 
script displays 65513 in the answer dialog. This, I believe is the RAW 
key code for the ALT key!


In other words, the optionKeyDown message is not sending the key pressed 
as a letter/character as the dictionary says and the parameter passed to 
the optionKeyDown message is the code for the ALT key itself (which 
makes no sense).


Could enough folks on this list conform both the macOS and Windows 
errors, so I can log a bug with LiveCode? I am not looking for 
work-around (I can do that if I have to), just for confirmation that 
these are bugs.


The macOS can be resolved by a better method for mapping macOS 
"high-ASCII" characters, now mapped to Unicode in LC, back to the ASCII 
key characters pressed.


The Windows may not have a work-around as, according to the dictionary, 
keyDown/keyUp messages are not passed in Control or Alt keys are down, 
the commandKeyDown, optionKetDown messages are sent instead, so you can 
using a keyDown handler and check for the altKey() = "down" condition. 
Perhaps rawKeyDown...

Thank you to everyone for the responses.

I hope that LC 10 will "fix" the systemVersion() to return customer 
meaningful OS version information, but I recognize that is hard to do 
when the OS manufacturers (I am looking at YOU Microsoft and Apple) do 
not update their OS APIs to return the same versions their MARKETING 
people insist on labeling the OSes as!

The discussion may seem academic to some, and perhaps pointless to others. But 
I like this sort of nonsense, and actually believe it is rather more than just 
that. In fact, it speaks to the internal working of the “sort” command itself, 
which seems counterintuitive at least, and a mystery at best.




I certainly agree a nice enhancement to sort would be something like

sort lines of  by item 3 of each then [by] item 2 of each then [by] 
item 1 of each


to replicate exactly (below) but in a single, easier to read, line

sort lines of  by item 3 of each
sort lines of  by item 2 of each
sort lines of  by item 1 of each

a reduction in code and a more intuitive way of stating a multi-level 
sort with the addition of a "then", "then by", or some sort of delimiter 
keyword


Still that assumes you want to do an ascending text sort for all 3 
levels, since ascending text is the default and the syntax is


sort lines  ascending text by item 3 of each

If you want different sorts for each key

sort lines of  ascending text by item 3 of each
sort lines of  descending numeric by item 2 of each
sort lines of  ascending international by item 1 of each

might still be easier that any new syntax that reads something like:

sort lines of  by item 3 of each ascending text then by item 2 of 
each descending numeric then by item 1 of each ascending international


Although the single line is slightly shorter code and still relatively 
easy to read. Still, I have NO idea how difficult it would be to add the 
syntax to the LC engine. If not too difficult to implement, it could be 
a handy enhancement to LC's sort.

All those forum efforts (except Richard's) ignore that the dictionary 
entry states that the "sort" command is a stable sort precisely so that 
you can do multiple sorts to sort by multiple chunks


Whether you do

  sort lines of tText by word 3 of each
  sort lines of tText by word 2 of each
  sort lines of tText by word 1 of each

or

repeat from i = 3 down to 1
  sort lines of tText by word i of each
end repeat

and whether you want to sort by "word i of each" or "item i of each" or 
"token i of each" or whatever, the multiple sort commands is the LC 
recommended way to perform  multi-level sort.
