LiveCode Forums.

I use the message box for testing and troubleshooting. I noticed that the message box keeps past commands. I don't know how long these items are kept but is there a way to clear all of the past message box commands?

Intersting question.

I think messages are saved forever. I have, just because. gone back in time with it, and gave up after many dozens. It got boring, though I remembered some of the things as they passed by.

Not sure how to clear them.

At least, clears out whatever current 'cruft' is there.

Poking around in revApplicationOverview I found these:
- -

Poking around a bit further, in the stackScript of the stack

revMessageBoxSingleLineMessageBehavior

[try saying that 10 times fast when you are lying drunk in the bath]

there is quite a lot of intriguing stuff such as:
which made me get fairly stroppy, as, obviously, the way messageHistory works CAN be modified, BUT is not made available
(as far as I can tell) in the Preferences.

Presumably (?) one can STOP the messageBox remembering past stuff.

I knocked together an impromptu stack with a single field and a button with this stack in it:
and got 200 lines of past guff/stuff/fluff I had put into the messageBox command field.

AND this:
threw a bluey.

OK, hang on a mo' maybe it's an array or something.

Oof:

This does the trick:

I've got a headache . . . off for some coffee.

Thank You! Thank You! Thank You!.
I tried poking around and couldn't find this.
I hope that others can use this information.
I will need some coffee just from reading your post.
One would think that Livecode would provide a button on the MessageBox to do this.

GREAT INFORMATION!

Just submitted an enhancement request:

After exploring all of this, was just one cup of coffee enough? Seems like one would need at least a whole pot of coffee or more.
Thank you for filing an enhancement request.

Why do I feel that LiveCode needs an awful lot more documentation?

Why do I feel that LiveCode needs an awful lot more documentation?

Language elements designed for us developers to use are generally documented in the Dictionary, and sometimes also in the User Guide and/or Lessons.

Functions, command, custom properties, and other elements designed for internal use only by the IDE are generally documented only in the code in which they're used.

This seems a reasonable level of effort, a pattern we see with a great many other such tools.

other elements designed for internal use

Surely, if I buy a car I can fiddle around with anything I like in it?
- -

AND, one could argue it is slightly high-handed of the folks at LiveCode central to assume that
certain elements are 'designed for internal use' only: and, certainly, I can see no obvious harm
in end-users being able to delete their command history from the Message Box.

The fact that LiveCode central has decided that some elements are 'designed for internal use' does not, also,
preclude the possibility of documenting them.

I bought a new dishwasher 2 weeks ago, and I have no chance whatsoever of understanding the
circuit diagram in the back of the manual; and I wonder who else has beyond the manufacturers:
but it is 'there' in the documentation; and should I or someone else be so foolhardy to try something
"clever" we will, at least, have a chance which we might not without that circuit diagram.

Richmond, fantastic detective work. Many thanks for your efforts on this.

I just check my message history and had entries spanning the last 6 months!

I see that Panos has already agreed that adding this as an option in the IDE would be a good idea...super!

In the meantime, whilst we are are waiting for this, I've add a plugin stack to Sample Stacks which will add a Clear Message Box History button to the IDE menu bar.

Look for ClearMessagesBoxHistory

Again great work.

The odd thing is that the multiline message box thingy seems a bit more awkward:

palette_rect_revMessageBoxMultipleLinesMessageBehavior would seem only to deal with the size of the thing.

Admittedly I have never used the thing, and, just now, having entered 2 lines of commands I cannot work outhow
to get them to execute:
- -

I see from other postings that other users have found this problematic.

Aaaaaah:
- -
I wonder if I hit that key several times I'll 'develop' a new custom prop. in the revpreferences stack?
