Getting license serial number

[Kenneth Ibrahim]

Simple question and hopefully 1 liner script answer :)

How does one poll the serial number of the currently running Maya session?

I tried the command 'license' but need to extract the serial number from the return unicode string given the 'info' option. That's fine though it seems that they would provide selectors for specific information.

I can go with this but it seems that all of the options to this command have been deprecated in Maya 2016 so I'll need different approaches with different versions.

Thx! Ken

```python
from maya import cmds
cmds.license(showProductInfoDialog=True)
```

just this command works in maya 2016

Thx for the info here. That actually caused Maya to hang (on Mac) for some reason.

Anyway, I'm trying to get the serial number programmatically without opening any dialog windows.

Yes, as far as I could tell there is no access to license info.

I know, it's just parsing text, but isn't text slice pretty much a one-liner anyway?

 

import re

import maya.cmds as mc

 

print re.search('serialnumber\t*(?P<serialnumber>[0-9-]*)\n',mc.license(info=True)).group('serialnumber')

 

It's not as clean as say, mc.license(serial=True), and I wouldn't write it out like that because it's awful to read, but it doesn't strike me as a particularly hairy task. You could even just patch in startup code in user.py to add the parse of the serial number etc into the os.environ dictionary so you could treat it like a system variable?

[Mahmoodreza Aarabi]

But Anthony, this line does not work on maya 2016 : cmds.license(info=True)
info flag is obsolete in 2016

May have been my misread, but thought the question as a general Maya one, with an exception needed for 2016.

 

2016 is a hard one to make a general case for because the entire lisc model is getting a bit of a shake-up so it depends on what is trying to be done (do products under subscription even have a serial number??) as to what kind of approach you'd do there.

maybe we can get serial number from the "Product License Information" window.

do you have any experience in this way? getting information of a window.

or at least if we can save information of this window to a text file we can easily access to information (like save as button)

If it's a QT window, sure, with a little probing you could probably track down the UI element and read out the string, but I don't really think it's worth the effort to do it and it's an awfully brittle process. There's a save as button which will dump the data to a text file, but again, unless there's a good reason to automate this *exact* specific process, I'd find another way. An example: if in 2016 they're still going to run licences via Flex, then surely it'd be easier querying the license server? (noting i have zero info about 2016, it's just not something on my radar right now)

Gentlemen, thanks for the ideas here. By a one-liner I meant if anyone knew of a different API call that would return the serial number alone (or have flags to do that). Parsing the info returned in 2015 isn't an issue but it's always better if the developer provides targeted API routines. And I was thinking that perhaps I missed some new callback that would work for both 2015 & 2016.
