Shell script / Python / Node / Newb lost ...

First. my apologies for posting in this sub, I'm not sure where I should post this.

I'm trying to add indigo support for my PlayStation 4. I can successfully wake the PS4 and launch apps on it with a command line tool called PS4-Waker, for which more info may be found here:https://github.com/dhleong/ps4-waker

It works well from the command line, so I tried converting from command line to shell script. I'm trying to excute the following shell script from the "Run Shell Script" server action:

Code: Select all

#!/bin/bash

/usr/local/bin/ps4-waker -t 30000


The script produces no effect or does not appear to run from indigo. However, if I double click on it in Finder, it will execute the script in Terminal and will generate the desired outcome.

It would still not work if I removed the -t 30000 (default is -t 10000.

I tried enabling the "Store the output of the script in a variable, but I'm getting the following error when I execute the action with the checkbox checked:

Action Collection Error Script /Users/myriam/Documents/Indigo-Scripts/ps4Waker-wake exited abnormally with a return code of: 127

after some more research, I stumbled on this thread http://forums.indigodomo.com/viewtopic.php?f=107&t=12148

So I decided to switch to Python to see if I would have better results

here's the python code:

Code: Select all

import subprocess

command = "/usr/local/bin/ps4-waker"
arg = "standby"

proc = subprocess.Popen([command, '-t 30000', arg], stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True)

out, err = proc.communicate()

indigo.server.log(u"command error: %s" % err)


here's the error that's logged in console:

command error: env: node: No such file or directory

Any idea as to what I should do to get it to work?

Ill have a look when I get downstairs, but additionally the source code for PS4-Waker is on GitHub in .js code - it wouldn’t take too long to turn that into full python code or a plugin.

That would be awesome! As you can tell, I’m not that good at scripting. I have a lot of ideas, but lack the knowledge to implement them!

Thanks for your time and your help!

Right, forget what I said about making it into a plugin or raw python - I hadn't realised it called libraries up and down the github tree. It looked like a one page script that at first glance looks perfectly doable.

So, onto calling the process in Python.

Code: Select all

import subprocess

command = "/usr/local/bin/ps4-waker standby -t 30000"

proc = subprocess.Popen(command, stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True)

out, err = proc.communicate()

indigo.server.log(u"command error: %s" % err)

See how that goes for starters.

With Popen, you either ["put", "arguments", "together"] in a list as shown, OR you "put them together" and set Shell=True.

You had done both which won't have helped things.

Thank you for the precisions!

I have updated the code and this is the error I'm now having

Script command error: env: node: No such file or directory

Try changing this line:

Code: Select all

command = "/usr/local/bin/ps4-waker standby -t 30000"

To this:

Code: Select all

command = "//usr/local/bin/ps4-waker standby -t 30000"

Try changing this line:

Code: Select all

command = "/usr/local/bin/ps4-waker standby -t 30000"

To this:

Code: Select all

command = "//usr/local/bin/ps4-waker standby -t 30000"

thank you for the suggestion. I'm still getting the command error: env: node: No such file or directory error.

What do you get when you the following script?

Code: Select all

import glob
files = glob.glob("/usr/local/bin/ps4-waker*")
indigo.server.log(unicode(files))

Hey Dave,

Thank you for your help with my code!

Ran the script with a slight modification as I had unistalled node to reinstall it in the non-administrator user on which indigo runs. This is the code I ran:

Code: Select all

import glob
files = glob.glob("/Users/myriam/.nvm/versions/node/v9.11.1/bin/ps4-waker*")
indigo.server.log(unicode(files))

here's the result

Script ['/Users/myriam/.nvm/versions/node/v9.11.1/bin/ps4-waker']

I then tried adding import glob at the top of my other script, but I'm still having the following error:

Script command error: env: node: No such file or directory

Heh. I'm not sure how I quoted myself up there, but I'll have to fix that.

The reason I asked you to run the script with glob is to see exactly how the command file would appear and that the script had the authority to see it. glob would have no effect on your script's ability to run.

How about this one:

Code: Select all

import subprocess

command = "/Users/myriam/.nvm/versions/node/v9.11.1/bin/ps4-waker standby -t 30000"

proc = subprocess.Popen(command, stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True)

out, err = proc.communicate()

indigo.server.log(u"command error: %s" % err)

Alternatively, if the above doesn't work, what about this:

Code: Select all

import subprocess

command = ["/Users/myriam/.nvm/versions/node/v9.11.1/bin/ps4-waker", "standby", "-t", "30000"]

proc = subprocess.Popen(command, stdout=subprocess.PIPE, stderr=subprocess.PIPE)

out, err = proc.communicate()

indigo.server.log(u"command error: %s" % err)

I tried both codes and I'm still having the same error. It's as if Indigo does not have access to node for some reason....

Did you run the glob script above from an Indigo scripting window or from Terminal?

From an indigo scripting window.

From googling, whilst still learning bash etc.....

The shebang line in ps4walker is calling “env node”.

Subprocess.Popen() has an env parameter.

Does adding env=node to the Popen Command help?

I’m on iPhone here so not gonna attempt to update the code line for you!
