#58775 — Couple of Xcode questions

So, I am wasting much time trying to get a simple AppleScriptObjC to
run. :-(

Question: Is there a magic incantation to change the font of the
displayed code ?

Edit -> Format -> Font -> Show fonts lets you choose fonts, but no
change to code.

Similarly, Edit -> Format -> Font -> Bigger has no effect,

When it gets late, one has to get bigger font (especially since turning
off text colouring has no effect, Xcode continues to insist to colour it).



Secondly, when compiling the Appescipt, is it normal that the only
details of a compilation error would be hidden into a pane you have to
click on and reveal:

slideprintAppDelegate.applescript:30: error: Expected “,” or “)” but
found identifier. (-2741)
Command /usr/bin/osacompile failed with exit code 1


I would have thought a modern IDE would have had some flashing arrow
pointing to the error in the source code. Yet, I find no indication of
where in the applescript an error was found.


Or did Apple disable the goodies between 3.1 and 3.2 to force people to
bguy Xcode 4 and beyond ?



Also, while I am at it, since there appears to be no debgger support for
Applescript, I am resorting to "display dialog". However, is there a
trick to display a numeric value ?

for instance:

set x to 24
display dialog  x

(I tried many incantations, but lack of proper compiler errors means I
operate in the dark).

I hate these newfangled languages with insufficient documentation.

Seems that contrary to what they say, "set myvar to 1" is not sufficient
to declare a variable.

In an AppleScriptObjC environment, it appears no code executes by
default.  And it *appears* that the "on <event>  <code> end" blocks are
treatead as subroutines, so if you want variables to be accessible
accross those blocks, they have to be declared as "global" at the top of
program.

(The doc and examples all said that a "set myvar to 1" at the top was
enough to declare the variable).

Also, it appears that the automatic coversion from number to string as
some of the documentation alludes is not so automatic.

my display dialog of a number was failing because the variable had not
been initialised and not availble to that block :-)

display dialog myvariable as string

does the trick.



Hours wasted because of that newfangled documentation. Long live the VMS
wall where you got the whole story on how stuff worked.

And now, I will have fun trying to integrate the serial port support. It
is likely 32 bits, and if I can't recompile it to 64 bits will have to
create my small simple app as 32 bits.



BTWm the "number formatter" in interface builder is really really basic.
It lets you enter anything of any length and only validates once you try
to leave the field. 1980s character cell tech did this live as you typed
and wouldn't let you enter a letter in a numeric field.

Ok, so this serial interface to appelscript provides and ".OSAX" file
put into scripting additions.

How does one add this to an xcode project ? (apparently it has a
dictionary with the valid statements etc, which would be visible in the
applescript editor, but not sure how this works in Xcode)

Why not just do it in AppleScript?

In what editor?

Um, that's not how script editor behaves for me, but you didn't say what
you were using.

osacompile? Are you writing in Xcode? Don't do that. Script Editor works
very well for almost all AppleScript work. You only want to resort to
XCode if you are building something complicated with lots of files. A
UI. Stuff like that.

You are using XCODE 3?!? The current version is 5.1.1

And yes, I'm sure Apple is very interested in the income derived from
forcing people to buy $0 upgrades to XCode.

To the best of my recollection:

display dialog (x as text) giving up after 5 seconds

Nope, they're more interested in the income from forcing people to buy 
the $whatever-the-price-is-today machine that *CAN* run the newest 
XCode.

xcode runs just fine on 5 year old macs, which means your statement is
complete bullshit.

I was under the impression that the last "free" version of xcode was 3.2
and that starting with 4, once needed a paid subscription to apple
developper to get the free xcode.

Is that still the case, or is xcode now freely downloadable again ?

would xcode 5 work on Snow Leopard ?

The normal Applescript Editor does not provide access to the Interface
Builder. It is means to script existing applications instead of building
a standalone one.

The use of Xcode is required when you want to attach a GUI (interface
buioder) to an applescript application.

you remember wrong. xcode is free with any level developer account,
including free) and also available for free on the app store.

OK, I need to add parity to my memory :-(

I was pretty sure at one point Apple started to require paid developper
subscriptions for Xcode upgrades (hence why I stopped bothering after
Xcode 3.2)

they didn't.

however, they did briefly charge for xcode on the app store, but all
you had to do was register as a free developer and get it for free that
way.

Hey... ...here's a CRAZY thought.

Why don't you actually check some of these things out...

...for yourself?

not easy because most of Google stuff on Applescript/Xcode interface
predates the change from Applescript Studio to ApplescriptOBJC.

And I had to do my own testing to find out that for Applescript Editor,
scripting additions placed in the Library/Scripting Additions are
automatically available to the Applescript app. Now, I must do the same
to see if they are also available to the AppleScriptObjC in Xcode.

I was hoping someone had gone through this before and could give some
hints that would have saved me archeological digs that have taken hours
so far to learn a tech that was meant to allow me to do this simple task
in a couple of minutes.

Keep whining about how hard it is...

Really? You had to do your own testing to find out what was already 
told to you in the ReadMe file that accompanied the scripting addition 
that I found for you?

"Installation:

Copy SerialPort X.oasx to ~/Library/ScriptingAdditions/ for a single 
user or /Library/ScriptingAdditions/ for multiple users
( ~ indicates your home folder).


Operation:

Open the SerialPort X dictionary in your favorite AppleScript editor.  
Look at the sample scripts to see how to interact with the Scripting 
Addition.  SerialPort X writes error messages to the console log."

Dude.

I could have written you the script in less time than it's taken you to 
whine about it.

AppleScript Editor has a "open dictionary" function. Xcode doesn't.
AppleScript Editor automatically finds files in Scripting Additions.
There is no documentation on whether Xcode does that or not.

There is documentation on how to produce a scripting addition in Xcode,
but not how to use one.

So use AppleScript Editor.

I've written most of the script while you've been making excuses.

Repeating for the Xth time: AppleScript Editor does not allow building
against interface builder. You need Xcode for that.

You need Xcode to link the properties defined in Applescript to the
fields in interface builder, and the buttons in interface builder to the
"on" code blocks in AppleScript.

Unless of fcourse I read wrong and that capability also exists in
AppleScript Editor along with all the AppleScriptObjC extensions needed
to work with interface builder's Cocia interface.


BTW, Xcode does seem to find the osax in /Library/ScriptAdditions
without having to add it to the project. Not very obvious in a IDE where
you are expected to explicitely specify all the libraries a project uses.

Will now have to try to run this on the server where there are real
serial ports.

But now, I have to figure out a way to bind the "return" key to a
button. IT seems to want it binded to a text field.

Why do you care?

You have a VERY NARROW task.

You want to send text strings to a serial port and have it 
auto-increment and then pause for you to hit OK.

Read this very carefully:

I have already coded pretty much all of it in AppleScript Editor.

The SerialPort scripting addition lists my available serial ports.

I need to code to open a port.

I get a dialog box that shows me the number the script thinks it should 
start with (based on a persistent property store with the compiled app).

I hit return.

I need to code the sending of the text to the serial port.

It increments the number

And repeats.

Hit "Cancel" in the dialog and the program ends.

Done.

I've had some success.

It is interesting that running the script on a machine without the
serial port entension does not generate any errors, except that the log
does have complaint about missing variable (which has been defined).


Also, when there is such an error in the

on applicationShouldTerminate_(sender)
		if theport > 0 then serialport close theport
		return current application's NSTerminateNow
end applicationShouldTerminate_


Then you must "force quit" the application, because of the error in the
"quit" code (complains about undeclared theport, but really about
missing definition of "serialport".



Once I got all setup on the server, the app was able to send data to the
serial port. Hurray !. But it does log this message to the console:

14-04-24 03:32:14 	slideprint[13337]	Performance: Please update this
scripting addition to supply a value for ThreadSafe for each event
handler: "/Library/ScriptingAdditions/SerialPort X.osax"


The source to that serial port osax is not provided. Is there a way to
fix it ? I can live with this as this app should not be used that many
times.

I missed this thread when it was current, and would have suggested Python
instead.  The advantages with Python are that there are tons of libraries
available AND lots of questions and answers on the likes of Stack Overflow.
