Re: compiler not catching bad exit within routine

[Bob Sneidar]

Another thing to try that helped me more than once is to copy/paste the script 
(the ENTIRE script not just the handlers) into a text file formatted for Text 
Only then copy/paste it back into your script replacing what is there. I think 
it has something to do with the unicode text thingummy.

Correct.

That should throw any error on script save--but it doesn't.

The rest of the script compiles, but this routine quietly doesn't.

RE: compiler not catching bad exit within routine

[Ralph DiMola]

I just had a problem like this minutes ago. I had fat fingers and must have
hit some bizarre ctrl key combo and LC(8.1.1) instantly quit with no
messages. I restarted LC When I opened the script LC was OK but when I
clicked the left bar to select the handler I was working on... BOOM LC quit
again. I restarted LC again, opened the script and selected the entire
script (15,000 lines) and copied it to the clipboard, then deleted the
entire script, I clicked Apply and then pasted the 15,00 lines back in,
clicked Apply again. I was now able to click on the handler I was working on
and go on my merry way(but not before I did a "ctrl S").

I didn't even have to go that far.

Pasting it into another script whole was enough for that; it gets found
there, and actually compiles & runs.

And to get it going, I added a new handler above it, and pasted a third of
it at a time, including spacing.

But that's the small stuff.

The real problem here is that the compiler is quietly failing.  the rest of
the script gets compiled, no error is thrown, and the problem can't be found
until another routine attempts to call this routine and it can't be found.


There *should* be an error whenever the compile fails to compile . . .

FWIW, this was the las hanger in that script, so I don't know what would
have happened to subsequent handlers.

Or try this if the script is not supposed to have any non-ascii characters:

local tLineCount, tCPCount
repeat for each line tLine in 

Re: compiler not catching bad exit within routine

[Dave Kilroy]

Ah right I get it now

Have you tried checking your script for invisible characters? Try copying
the entire script to something like BBedit, selecting and copying it afresh
there, deleting everything in the LiveCode script, saving it to ensure it's
clean, pasting in the (hopefully cleaned) script from Bbedit and finally
saving...

just checked; and no.

And strict compilation is on (although it seems to keep getting turned off).

Yeah, I think that's the point of the original post.

My guess is that there's a "makeNewDnaRec" variable somewhere in the
original script.

That's my usual approach, but it failed here.

And cut & paste into another stack worked.

I then came up with a completely new name, and copied a few lines at a time
into the new handler, and it worked.

Something's rotten . . .

The rest of the script compiles, but this routine quietly doesn't.

Re: compiler not catching bad exit within routine

I've no idea what the problem could be, but when things like this happen to
me I copy the routine and continually delete lines until either I discover
what I did wrong, or have a very minimal test case.

compiler not catching bad exit within routine

[Dr. Hawkins]

I have a (much longer) routine to the nature of

on mkNwDnaRec


if something then

exit makeNewDnaRec

end if

end mkNwDnaRec



The compiler doesn't choke when saving the editor window.

It does, though, file to go to mkNwDnaRec stating that it can't find it.

I then paste the routine into another script, and it catches the error.

Paste it back, and it still isn't caught.
