because I don't here it is repeated:

(and just to add to this list, my Text Editor does all these items for 56
code syntaxes, and at least 21 actual langues like Chinese, Korean etc etc)

Off the top of my head:

1) copy & paste via keyboard
How many times have you copied from somewhere external and you can't
use the keyboard to paste it into LC. Either you need to use the mouse+menu
or the data isn't even there - in which case I find myself pasting the data
into a text editor, copying it again and then pasting into LC. (this is
more a long standing bug of LC and not just the SE)

2) customiseable keyboard shortcuts
It's just nice and convenient to be able to allocate ANY of EVERY
single menu item a keyboard shortcut. Time saver.

3) more script space, less wasted space
Because the SE doubles as the debugger it has a LOT of wasted space. I
want my SE to be 90% text, the rest tools and nicities, like my TE. I want
my debugger sort of the opposite, 40% script and the rest debugging info -
typically I can't see enough variable values. As someone else pointed out,
why can't I view Variables and breakpoints concurently when debugging? Why
does the Error message need as much space as the Variable viewer? I've
never seen one that's taken up more than two lines, and even then it could
all be displayed on one line. Effecient workspace.

4) autocompletion
The flexibility of not using explicit variables with the safety net of
spelling them correctly all the time. Time saver.

5) spellchecking
Can load custom dictionaries so whilst mine generally checks I spell
colour correctly, for LC work I can make sure I spell it the other way.
Time saver.

6) boilerplates
I can type in switch and a little popup will come up with switch3,
switch3d, switch4, switch4d,... switch9, switch9d. I can either click on
one or type switch5d and press return and a bare switch statement with 5
case entries will be created for me including the default structure. If I
didn't specify the d at the end, no default structure is included. Actually
99% of the time I use the switch default structure as a place to catch
logic errors so my boiler place includes:
default
answer "A Case I Haven't Considered. Check the Variables." titled
"Switch Case Error"
breakpoint
end switch

All typed out for me automatically. Time Saver

7) Inbuilt scripting
Strange that for a scripting language this is listed. Take this SQL
statement:

SELECT * FROM table WHERE f1 = "AA" AND f2 = "BB" AND f3 = "DD"

if I need to do this:

put "SELECT * FROM table WHERE f1 = "AA" AND f2 = "BB" AND f3 = "DD""
into tQuery

it will not work because of the quotes in SQL have a different meaning
to LC so I need to replace all those " with " & quote & " - except the
first and last ". Yes, I appreciate I could do it manually with Find and
Replace but that's slow, or I can modify LC to allow me to run a script to
do that selective replacement similar to what I do in my TE, but I'm just
surprised at how much easier it is to do im my TE and just a keystroke a
way. Time saver.

8) folding
The ability to collapse a handler, control structure, multiline
comments down to a single line - an absolute godsend. Again I want the text
I'm interested in to cover 90% or more of my screen. So many times,
portions of what I'm focusing on are spread over just more than what is
displayed in the SE - why is that? Copy and paste into my TE and most of
the time I'm sweet, but often enough I wish I was able to collapse a 5 case
switch statments down to a single line and remove the 4 line comment
because then what I need to be looking at would all be viewable. Can be
done with other languages. You wont appreciate it until you've used it.

9) bracket pairing
How many times has your code been in error because of a mismatch in
brackets? Every TE worth it's salt provides some sort of indication of
bracket pairing, not just whilst you type the brackets, but also you can
come back and click on a bracket and it's mate will be hilighted. Also, an
unmatched bracket is highlited immediately, not when you go to Apply/Save.
Time saver.

10) search and replace remembered
The last 10 searches and replacements are stored, although I think
that's only because I set it to 10. As most of my search and replace are
regex, and I'm NOT very good at it, having these saved is extremely
convenient. Nice feature.

11) regex search pattern validation
Any serious work with text will at some time require a bit of regex.
Whilst building regex search and replace patterns my TE automatically
validates the code. To be fair, LC has a built in Regex Builder so you can
test your regex prior to use, but this isn't quite as nice

Whilst there is no denying that, I can only think of 2, maybe 3 stacks
recently that required more than 4h grade math, and even then I used Google
to find the equations I needed ;-) By far the majority of math in my
scripts is simple addition, subtraction, or comparison (>,=,<).

I think you could get quite far with LC with only very basic math skill - I
think a logical or systematic mind would serve you better. I've certainly
created many many stacks that contain no or very simple math.

Then again, many would look at my code and be horrified ;-(

For this one at least, you can adjust the bottom pane to any height that's 
convenient. I change it frequently depending on what I need to see.

Re: Char Set on Custom Properties

2015-09-04 Thread Mark Waddingham


On 2015-09-03 21:38, J. Landman Gay wrote:

Returning to this topic...we are in the process of creating new stacks
in LC 7 while still running older LC 6 stacks with the same app.
Stacks have custom properties containing text created on a Mac, and my
app uses MacToISO() to display the text when running on Windows.

Some of the LC 6 stacks will be edited and saved in LC 7, others will
remain as LC 6 for a while. My app needs to know whether the character
set has already been converted so it can display text correctly. Is
there a way to tell in a script?


Hmmm - this is somewhat tricky.

From what you are saying you want people to be able to edit content in 
both LC6 and LC7, the content itself being saved in LC6 format. i.e. You 
want to move your system forward to LC7, but you need to still support 
LC6 clients and editors. Is that correct?


Now, LC7 will assume that custom property values coming from LC6 format 
stacks are binary data thus won't do anything magical with them. 
However, as soon as you pass that value through anything text-related in 
LC7 and set the custom property back, it will be (in memory at least) 
stored as text. Then, when you save the stackfile in LC6 format the 
engine will convert the text to the platform encoding and save as binary 
(which is what LC6 expects).


Of course, having just written that there might not be a problem here. 
If you are still intending to save all your stacks in LC6 format then it 
should be fine. You still need to do macToIso / isoToMac in LC7 since it 
will only be loading things in LC6 format - a problem would only arise 
if you were sometimes saving your content stacks in LC7 format.


In terms of moving forward what you might want to consider is 
transitioning to storing your text in custom properties in UTF8 format. 
So, rather than using macToIso / isoToMac you decode the UTF8 into text 
in both LC6 and LC7. This means you can continue to use LC6 format, but 
at some point in the future ditch LC6 support and then you'll be able to 
start using unicode in your text without any problems. (To be fair, you 
could still do that now - its just that in LC6 clients / editors, any 
unicode characters would appear as ? as they wouldn't be in the native 
encoding).


Hopefully that's not too confusing :S

Mark.

export snapshot with acceleratedRendering

2015-09-04 Thread Dan Friedman

On either the iPhone simulator or an actual device, if acceleratedRendering is 
enabled and I do:

export snapshot from rect (the rect of this card) to pictVariable as PNG

I get a solid grey image.  If I never enable acceleratedRendering, then the 
image comes out fine.  It seems that once acceleratedRendering has been 
enabled, your hosed.  I even tried this:

set the acceleratedRendering of this stack to false
export snapshot from rect (the rect of this card) to pictVariable as PNG
set the acceleratedRendering of this stack to true

But, I just got the grey image again.  Is there some magic property I have to 
set to take a screen shot on a mobile device if acceleratedRendering is enabled?

Any guidance is appreciated!

LC 7.0.1

Re: export snapshot with acceleratedRendering

Try doing from rect ... of this card. I think the form you are using is doing a 
screen buffer grab, which doesn't play so well with the OpenGL surface 
accelerated rendering uses. The of this card form renders things into an off 
screen buffer rather than trying to access the display buffer.

6) boilerplates

I meant to respond to this one too. Boilerplate is pretty easily added 
yourself by use of a frontscript. The frontscript handlers check to see 
if the target is the script editor and if so, executes whatever you 
want. I have been running my own frontscript with dozens of shortcuts 
for about 15 years and it works great. You can have any customized 
behaviors or text insertions you want. I know at least a few others are 
doing this too.


I do understand that you're asking for a universal change to the editor, 
and I think a skeleton switch construct would be a good one, but it 
would be difficult to anticipate the variety of needs for every 
scripter. So for me, my solution is ideal. It is set up as a plugin that 
opens invisibly when LC starts up and inserts itself into the front. 
It's so seamless I forget it's there except when I want to add something 
to it. Its shortcuts are hard-wired into my brain and I would be lost 
without it, it speeds up so many scripting actions.


There are at least a few advantages to having the editor implemented as 
a regular stack that responds to normal LC commands. ;) Maybe with 
enough interest, the frontscript idea could be generalized to allow 
every scripter to add their own boilerplate options, and it could be 
shipped with LC.

Pretty much. There are hundreds of stacks out in the field, in use by 
end users. We're starting to move to LC 7 and I'll build an app 
eventually with that version, which all users will update to. New stacks 
created from now on will be made in LC7 (if all goes well; there are 
some issues I'll be reporting.) The LC7 app can read both the existing 
LC6 stacks and the new LC7 stacks, which is good, but my scripts need to 
know whether to use MacToISO() or not before displaying the text.




Now, LC7 will assume that custom property values coming from LC6 format
stacks are binary data thus won't do anything magical with them.
However, as soon as you pass that value through anything text-related in
LC7 and set the custom property back, it will be (in memory at least)

Right, I think I understand that part. The problem is that we have many 
LC6 stacks in use and new LC7 ones coming out, so the scripts need to 
know which type they're working with. It sounds like the engine bases 
its decision on the stackfileVersion saved with any particular stack, 
which would be fine for me too if we could access that, but right now 
its only a global property. I could really use a "stackfileVersion of 
this stack" command right now. That would solve the problem.


Barring that, I thought of reading a sequence of bytes from the stack 
file, but I can't because these stacks are streamed remotely and have no 
filename. I don't believe there's way to read the raw binary content of 
a stack in RAM, so I'm kind of stuck.


Is there some kind of scripted test that might determine the 
stackfileVersion of any particular stack in RAM?

Re: export snapshot with acceleratedRendering

2015-09-04 Thread Dan Friedman

Mark,

Ok... I found the combination that works.  This assumes you have opened a stack 
and acceleratedRendering is enabled:

THIS FAILS (produces a grey image):

lock screen
export snapshot from rect (the rect of this card) to pictVariable as PNG
//do some stuff
unlock screen

THIS FAILS:

export snapshot from rect (the rect of this card) to pictVariable as PNG
lock screen
//do some stuff
unlock screen

THIS ALSO FAILS:

lock screen
set the acceleratedRendering of this stack to false
export snapshot from rect (the rect of this card) to pictVariable as PNG
//do some stuff
set the acceleratedRendering of this stack to true
unlock screen

THIS WORKS:

set the acceleratedRendering of this stack to false
export snapshot from rect (the rect of this card) to pictVariable as PNG
lock screen
//do some stuff
set the acceleratedRendering of this stack to true
unlock screen

So, the screen must not be locked, and acceleratedRendering must be off.   Not 
sure if you call that a bug or not... but it's working.  Hope I don't have 
issues when I try it on Android.

Thanks!

It hadn't occured to me, actually. I could only set the property on the

or…

   export snapshot from this card to pictVariable as PNG

— Works regardless of the screen lock or acceleratedRendering by not using the

It's not harder. I'm saying it can't be accepted as a community
contribution, because whichever way you slice it, it involves binary
stacks.

I thought that was the purpose of the 'BugFix:' or 'Feature'
prefixes for bug reports, i.e., here's what's wrong and here's
how to fix it.

It's on a computer, Ali - ultimately everything is binary. :)

Let's not let Github's limitation impede meaningful work.

What we need is a way to ensure that the changes applied are the changes 
we want.

Format is a distant second to that, merely a means to that end and 
something we can overcome.

Let's brainstorm ways to fix this critical problem holding up so much of 
the work we could be sharing.

It may not be Github, but it doesn't have to be.  Github was designed 
for C programmers working on the Linux kernel.  Different problem, 
different tools.  If we need a uniquely-LiveCode solution to assist with 
some parts of IDE development, well, it wouldn't be the first time 
LiveCode's unusual nature requires fresh thinking.

After all, the reason we're all here is because LiveCode isn't like 
everything else.

Let's do this.

Rectangle detection

2015-09-04 Thread Peter Reid

I'm trying to detect and extract a rectangular area of an image.  The image is 
a graph with some parameters that are always contained inside a rectangle.  The 
graph consists of curves and axes in black on a white background.  The 
rectangle is a box consisting of black lines and it contains black text on a 
white background.  I need to extract the box alone so I can run it through an 
OCR process to convert the key parameters inside the rectangle into text for 
other purposes.

Can anyone suggest a method, script or add-on for LiveCode that will help me 
extract a rectangle from its surrounding image?

Thanks.

Does the rectangle always appear in the same location in the image and is
it always the same dimensions?

Can you post a sample?

Oops, meant to add: if the size/location of the rectangle is always the

rectangle's rect.

If the rectangle doesn’t always appear in the same location or is not always 
the same size, is the image always the same width?

Re: Rectangle detection

2015-09-04 Thread EED-wp Email

Peter,
I think you are going to have to analyze the pixels of the image using the byte 
values. Look in the sample stacks for image processing code. I am on the road 
until mid next week and if you haven't gotten started by then I will send you 
some code that can get you started. 

If the rectangle box is arbitrary, you will have to search the image data for 
the horizontal and vertical lines of the box in the image. There may be other 
tricks you can do by moving line objects with particular rendering options 
while checking the adjacent pixels. 

But, ideally someone on the list has already solved this problem and can offer 
finished code. 

Good luck?
Bill

License server

It seems that there is no longer a license server when installing new 
copies of LC4 or LC5. The only way to install LiveCode versions earlier 
than the LC6 opensource builds is to create a license file on the

I do too, and I'm very thankful for that ability, what I guess I'd like is
for the IDE to read my mind ;-) or at least just remember some basic
defaults. When I start typing in the Script field, I must be Editing a
script so I'd like the "Errors Pane" to come to the fore and automatically
reduce to two lines - as I've never seen an error that requires more than
two lines. I Save VERY frequently (even when I know my script is in a state
that will produce an error) so the most likely thing that is going to
happen is a compilation error needs to be displayed so I have the Editor
field as large as possible and the Error pane ready to go. When I 'use' my
stack and we hit  a breakpoint, clearly I must be in Debugging mode, in
which case my preferences are I only want to see a half dozen lines above
and below the breakpoint, I want to see the Variables so I'd like the
Variable pane to be shown - if there are few variables then show me them
all and the rest of the area can be script, if there are a LOT of Variables
and it's not possible to display every single one of them at least expand
the pane up to the point where my preferred minimum dozen lines of script
are left displayed.

I appreciate that for some this would be completely annoying but by the
same token I think many would appreciate if those 5 panes (Errors,
Documentation,Variables, Breakpoints, Search Results) had a Preference for
Manual (Exactly the same as now) or Automatic and if you selected Automatic
you could list the minimum number of lines to be displayed in the Script
Editing field respective to each pane, so clicking on the Variables pane
would automatically adjust it's size to display as many Variables as
possible but not so as to reduce the displayed number of lines of your
script below your minimum, and changing to the Breakpoints pane would again
automatically adjust the size of the pane.

Yes, and I think I made mention of this with reference to another item,
it's not that I don't know that I can implement this in LC, it's the fact
that my TE makes it so much easier. The idea of a community driven effort
is a good one.

And this all boils down to the crux of the issue - I'm bone lazy! ALL the
points that I mention I could script into the IDE for my own personalised
perfection of Script Editing and Debugging; that is the beauty of LC. But
instead of spending the time doing that I find the tool that gets me 95% of
what I want in 1% of the time and I go with that. I just don't have the
time to script all of that when I can double click on my TE Icon and all
those features are available in the blink of an eye.

And for any List Lurkers out there, please do not get me wrong. I will
happily live without these features in LC's Script Editor because the
reason I use LC is not because of it's script editor. The reason I use LC
is because I NEED it to help me work with reams and reams of disparate data
and LC is the ONLY language that clicks with my brain and allows me to do
far more than I could every have hoped for. For the very minor quibbles I
have with the SE, it is NEVER going to stop me coming back to LC time and
time again to throw together quick and dirty utilities to solve the most
obscure and obtuse problem of the moment, or continuing to improve, modify
and extend a multi-stack behemoth I use weekly in my work that has just
snowballed from something I started about 15 years ago - probably even
longer if I really looked into.
