Run multi-line Python script within AppleScript?

This has been driving me crazy. I want to run a multi-line Python script within an AppleScript script (no .py file). I'm using Indigo 7.4.

Specifically, I want to to check the onState of a device, then turn that device on or off accordingly, similar to toggle, but conditional on the onState.
If onState is "on", turn the device off, and vice versa. Sounds simple to me, but I can't figure how to do it. I'm a "lite" user of Python.

Can this be done? If so, how?

I have no idea if what you're trying to do is possible, but I recommend you don't even try. Just convert the AppleScript to Python and be done with it. You're going to have to sooner or later, so might as well do it now.

I saw your post this morning as I was rushing out and thought "nope, i'll let FlyingDiver answer that"...

I completely agree with what he's said, just don't even try.

In terms of python, the following single line will do what you need if you really want it in a single line:

Code: Select all

indigo.device.turnOff(796740025) if indigo.devices[796740025].states['onOffState'] else indigo.device.turnOn(796740025)

The syntax is:

some_expression if condition else other_expression

Turn it off if it is on else turn it on

A better multiline approach would be:

Code: Select all

myDevID = 796740025
devIsOn = indigo.devices[myDevID].states['onOffState']
if (devIsOn):
   indigo.device.turnOff(myDevID)
else:
   indigo.device.turnOn(myDevID)


Thanks very much. I want to use AppleScript for this, run from (Many Tricks) Butler, which does not run Python scripts directly. I just assumed it would be straightforward to encapsulate a multi-line python script in AppleScript, but apparently not. I will try running a separate ".py" file from AppleScript then.

Follow-up:

This works,

Code: Select all

do shell script "/usr/local/bin/indigo-host -x '/Users/billearl/Desktop/fan.py'"

where fan.py contains,

Code: Select all

myDevID = 100076704
devIsOn = indigo.devices[myDevID].states['onOffState']
if (devIsOn):
   indigo.device.turnOff(myDevID)
else:
   indigo.device.turnOn(myDevID)

Now, I just want to find how to pass the device ID from AppleScript to Python so I can use just one ".py" file to control different devices.

Any ideas?

Untested by I think you can just do :

Code: Select all

do shell script "/usr/local/bin/indigo-host -x '/Users/billearl/Desktop/fan.py ' + dev_id"

then:

Code: Select all

# best to test if argv[1] exits and trap or default
import sys
myDevID = sys.argv[1]
devIsOn = indigo.devices[myDevID].states['onOffState']
if (devIsOn):
   indigo.device.turnOff(myDevID)
else:
   indigo.device.turnOn(myDevID)

Thanks. Unfortunately, I can't seem to pass a variable from AppleScript to Python that way.

I tried AppleScript,

Code: Select all

set dev_id to 100076704
do shell script "/usr/local/bin/indigo-host -x '/Users/billearl/Desktop/fan.py' " & dev_id

with Python ("fan.py"),

Code: Select all

import sys
myDevID = sys.argv[1]
devIsOn = indigo.devices[myDevID].states['onOffState']
if (devIsOn):
   indigo.device.turnOff(myDevID)
else:
   indigo.device.turnOn(myDevID)

but the device did not respond.

Another test using,

Code: Select all

import sys
print(sys.argv)

seemed to indicate nothing was passed from AppleScript to Python.

Try:

Code: Select all

set dev_id to 100076704
do shell script "/usr/local/bin/indigo-host -x '/Users/billearl/Desktop/fan.py " & dev_id & "'"


Need to get the device ID into the single quoted string.

That results in an error: (from Script Debugger)

You've got an errant colon in that line.

So it would appear from the error message, "main(sys.argv[1:])", but there are no colons in my code, except for the two colons in the Python if - else conditional. I can't explain why the error message contains what appears to be an extraneous colon.

Yeah, the problem is actually that the indigo-host script only accepts a valid path for the -x option. No additional arguments allowed.

There's probably some other way to skin this cat, but they're going to be more convoluted.

How do I get a man page for indigo-host? I'd like to see the options available. Thanks.

I don't think there's a man page for indigo-host.

Code: Select all

Dave@my-mac ~ % man indigo-host
No manual entry for indigo-host


I believe all the helper apps are in usr/local/bin.

It’s a Python script. I just read the code.
