Thanks to you all!

This list is a treasury.

case sensitivity of the keys in an associative array

[francois.chaplais via use-livecode]

Dear list

From my current work on a LiveCode project, it seems that the keys of an 
associative array are not case sensitive.

For instance, I may define 
theArray[« Ddt »]

If I define now  
theArray[« ddt »]

this entry replaces the previous one (forgive apple mail which replaces my 
double quotes by french double quotes)

Is this behavior confirmed?

Best regards
François

A question about the compiler to come

[francois.chaplais via use-livecode]

Dear all

You probably have received some mail asking for funding concerning a compiler 
to come.

I would like to know if this compiler can target MacOS/ARM processor on the 
desktop.

Best regards,

François

Re: For the Mathematicians.

[francois.chaplais via use-livecode]

In
https://en.wikipedia.org/wiki/Lemniscate_of_Bernoulli 

use the formulation in polar coordinates.
You sample theta, compute the corresponding radius r, convert the polar 
coordinates to usual cartesian coordinates, and draw a line between each point 
for successive angles theta.

This is an explicit formulation (up to the sign or r, but the figure is 
obviously symmetric with respect to the origin).

Bug survey

[francois.chaplais via use-livecode]

I wanted to answer the LC bug survey. 

The problem is that there is probably no bug number for my problem.

So here it what I wanted to answer to the first question in the survey:



I am on MacOS Big Sur, 11.6.1 (20G224). Latest 27''  iMac, Intel Chip, 8 cores 
i7, 64 Gigs RAM, 4 TB SSD, etc.. 

I have the latest stable build of Livecode (9.6.4 | Build 15551).

When I want to activate a menu item in the Livecode menubar, it constantly 
takes more than one second to react. The Livecode menu. The File menu. Using 
the menu to quit Livecode is for the intrepid.

This is the first impression that I have of the current Livecode app, and it 
discourages me to even try this version.

This should be a no brainer for a 2021 app.




Best regards,

François

Re: Catalina is a small, rocky, and largely unprepossessing island.

[francois.chaplais via use-livecode]

I suggest trying Go64 
https://www.stclairsoft.com/Go64/
which tests your apps for 64 compatibility. My business LC seems OK, I have two 
versions of indie for HTML and go64 indicates that the app is 64bits except for 
the update module.
Now I do not know what Catalina will do with this. Nonetheless, I think it 
should be no hassle for LiveCode to recompile their update module.
Best regards
François
