Can Message Box retain messages?

[dunbarx at aol.com]

I modified the message field script in the message box to build a history of entries. It is considered dicey to meddle with IDE scripts, but this has never caused a problem. I just modified the enterInField and returnInField handlers resident there, passing the current contents to a list field I keep in a toolbox stack.


During development, I am constantly sending msg commands, sometimes with slight variations, sometimes the same one over and over.  The gadget eliminates duplicates, and allows me to quickly choose from all the ones I have used. I can execute from that list, or reload into the msg box itself if I want to change an old command before sending.

OK, Bob. Here goes...

Be advised I'm a LiveCode newbie so everyone feel free to turn this into a
lesson on what I should have done different.

Steps to make a Log substack (Message box output alternative)
1) Make a new substack named "Log" containing a card named "Log" containing
a scrollable field named "Log"  Stretch the field to fill the card.
2) Configure those as you wish. (Mine has the stack set as a palette window,
the "Log" field's autoHilite OFF and line wrap enabled.)
3) In the mainStack of my project, I put this script:

on log thisinfo
   if thisinfo is "clear" then
      put "" into fld "Log" of stack "Log" -- empties the log
   else
      put thisinfo & RETURN after fld "Log" of stack "Log"
   end if
end log

4) Finally, for any message you want to send to the log, call the log
handler from your code:

log "my whatever"

I use this for debugging to record a breadcrumb trail of handlers and
events, and to record changes to variables over time. The one thing it isn't
doing, so far, is outputting arrays. Do I need to split those first?

Does LC have a command to evaluate the type of an object or variable? (Such
as Director's "ilk" command?)

Comments? Improvements?

Thanks,
Tom Bodine
