I'm giving another go to learning Apple Script, using Script Debugger
3.03 to help.
A couple of years ago I devoted a bit of time to learning, but it
didn't pan out (my time, I mean...) I have some experience with
scripting ARexx, a "Basic", non-OOP language, so I'm not completely
approaching this from square one; but at times it feels like I am...
I've been slowly moving through Danny Goodman's book and have come to
the "offset" command from the basic Scripting Addition commands.
First off, I got a couple of errors so I looked all over but couldn't
find a list of error messages and their numbers. Why is that? Isn't
this a common feature of languages? Anyway, it seems that the
language has changed since this book was written because I got
compilation error "-2741" on the word "Document" on this line:
choose file "Locate the file "Offset Document":" of type "QUIL"
[the error dialog reported-> "Expected end of line, etc. but found
class name."]
--I don't understand... (I got rid of everything after "choose
file", and the script worked fine, but what happened?)
-----
This script is using the "offset" command as a way of doing a search
and replace.
After a line where the script indicates to use its own local
subroutine, it has this line to tell what the replace string should
be:
given replaceString: "SuperSubScript Plus"
When I typed this line I mistakenly omitted the colon, but when I
went looking for the syntax of the "given" command, I couldn't find
it anywhere---I don't even know where it came from. A scripting
addition? Script Debugger?
Also, when assignments are made within the body of the script are
they automatically "exposed" to the internal code of the subroutine?
I mean does the subroutine "know" about all the assignments in the
rest of the script? And if so, is there a way to isolate the
subroutine so its internal code is separate from the body of the
script?
Has anyone put together a program that has all the common commands
most often used by Apple Script scripters? It seems like that would
be very useful. You could click on a keyword and be told not only
the syntax, but where it came from.
Can anyone clear some of this up for me?
Thanks,
Greg
