Re: What makes everything on a card unresponsive?

[Brian Milby via use-livecode]

Look into the log command.  When you disable that, there is no performance 
impact and you don’t need to remove all of the individual calls.

Thanks,
Brian

Re: What makes everything on a card unresponsive?

[Graham Samuel via use-livecode]

Thanks Mark - I am very glad you reminded me of the way puts go into the 
console window. I knew about that once (two or three  years ago, when I last 
tried to do a mobile app) and just forgot about it. I have kind of emerged, 
blinking, into the light after being in the dark for a long time.

I also do the trick of having a “debug” scrolling field on the most frequently 
seen card, and I have a tiny handler which accepts text and puts it into the 
next line of the field. When the app goes live, I can remove all the calls to 
the handler or simply arrange for the handler to have nothing in its script - 
the speed hit on the kind of app I’m interested is negligible, I find. And I 
also use ‘answe'r in an emergency, tho of course it disrupts the flow of the 
app.

I think the remote debugger doesn’t work with Indy, but i’ll check.

By the way I traced down the actual problem I had when I wrote my original mail 
in this conversation, using the methods you mention. It seems to be something 
to do with a widget that’s supposed to provide a native-appearance switch. I 
have isolated it and can continue to work in other ways for a time.

Thanks very much for the input.

Graham

I use:

--quick a dirty value check
 answer “VariableName:” && tVariable

—did my code get this far
answer “Handler name, label that may provide extra context”

—breakpoints
Sometimes the remote debugger works and sometimes it doesn’t. When it does, you 
breakpoint will fire in your app and show up in the LC IDE

—console
You can open the console app on your Mac. On the left side of the console, you 
will see your plugged in device. Click on that.
Any empty puts like:  put “My code got this far”
These will output to your console.

—debug field
I put a field called “debug” on a card I am working on. I can output what I 
want to that field when I want to check the state of things.

These are some tools I use to work on mobile.

Native Switch Button Widget [was: Re: What makes everything on a card unresponsive?]

[Graham Samuel via use-livecode]

My ideas were wrong. What I think now was that the whole of my app was halted 
by the existence of a Native Switch Button widget on the card I was trying to 
go to. I am not sure if I have time to prepare a proper bug report, but i found 
it by a process of elimination of all other objects on the card. Of course the 
widget might work in other circumstances. I will try to do a few more tests.

Has anyone any experience of using this widget successfully? Perhaps I  need to 
start another conversation about these Native-look widgets.

not sure, but I don't think so.

What if you comment out the "locationchanged" handler?

Re: What makes everything on a card unresponsive?

[Graham Samuel via use-livecode]

Hard to extract, but I have a new idea - what if the message queue is being 
swamped? I have flimsy evidence that the simulator is generating 
locationChanged message (odd, because I don’t think it really has changed). Can 
I interrogate the queue?

Just feeling my way.

any script? card, front, back, behavior?
A loop that can get stuck?
Accessing a file that is not there?

Maybe you can post your card script of the "menu card".
