Hi,
The problem is that if you are doing something like this:
if the script of myObject contains "on HandlerName" then
send HandlerName to myObject
end if
This this will work if the Hander is NOT commented out, but will fail
with an error if the handler IS commented out. Also if you have a
comment in a Script that just happens to contain "on HandlerName"
then the "if" will succeed even though there is no handler defined.
I had a problem that took me ages to figure out. In a script I had
something like the following:
--on Update make sure the field is not selected
which meant that:
if the script of myObject contains "on Update" then
succeeded, but the send statement failed since there wasn't really a
handler called "update" defined. Checking for "end Update" *may* have
worked, as long as there was not a line that read something like:
send Update to myObject
Also checking for "end Update" slows the whole process down.
What would be nice is the ability to check if a (real) handler exists
not just that the script contains text that looks like a handler
defintion. Something like this would be good:
if exists(handler "Update" in script of myObject) then
Which would make it 100% foolproof.
All the Best

Commenting would only affect things if the wholeMatches is set to
true - normally, lineOffset will get the right line even if it's
commented out, no?

Hi,
Of course none of the solutions so far work if the function is
commented out. To make the code 100% foolproof is a lot of work. I
was doing something similar and found that comments made life
really difficult.

Perhaps using
set the wholematches to true
put lineOffset("on" && pHandlerName, pScript) into tStart
if tStart is 0 then put lineOffset("function" && pHandlerName,
pScript) into
tStart
put (lineOffset("end" && pHandlerName, pScript) +1 into tEnd
answer tStart & cr & tEnd

Unfortunately, wholematches can't be used, at least for the first
lineoffset, because there are likely some parameters further in
that line. The alternative to lineOffset is to use regex.
A truly generic function would need to know whether it searches
for command or function, because it is possible to have one of
each with the same name.
