Hi,

I have some patch to apply in order, so I have to sort my list which came from an RPM...

By default my list is sorted like this :  
/update/v902002.5\_p05.0\_00\_0  
/update/v902002.5\_p05.1\_08\_0  
/update/v902002.5\_p05.1\_08\_1  
/update/v902002.5\_p05.1\_08\_10  
/update/v902002.5\_p05.1\_08\_2  
/update/v902002.5\_p05.1\_08\_3  
/update/v902002.5\_p05.1\_08\_4  
/update/v902002.5\_p05.1\_08\_5  
/update/v902002.5\_p05.1\_08\_6  
/update/v902002.5\_p05.1\_08\_7  
/update/v902002.5\_p05.1\_08\_8  
/update/v902002.5\_p05.1\_08\_9

I would love an ansible way to do sort with perhaps a specific option to do like the linux sort with option -V which give me this :

/update/v902002.5\_p05.0\_00\_0  
/update/v902002.5\_p05.1\_08\_0  
/update/v902002.5\_p05.1\_08\_1  
/update/v902002.5\_p05.1\_08\_2  
/update/v902002.5\_p05.1\_08\_3  
/update/v902002.5\_p05.1\_08\_4  
/update/v902002.5\_p05.1\_08\_5  
/update/v902002.5\_p05.1\_08\_6  
/update/v902002.5\_p05.1\_08\_7  
/update/v902002.5\_p05.1\_08\_8  
/update/v902002.5\_p05.1\_08\_9  
/update/v902002.5\_p05.1\_08\_10

Is there's such an option of sort available ?  
If not, is there a way to achieve it ?

Thanks

Regards,

JYL

Currently we have [http://jinja.pocoo.org/docs/2.10/templates/#sort](http://jinja.pocoo.org/docs/2.10/templates/#sort),  
which does not seem to support a 'numeric' option. A custom filter  
would be required.

Elaborating a bit, see [https://natsort.readthedocs.io/en/master/index.html](https://natsort.readthedocs.io/en/master/index.html).

First "pip install natsort".  
Then create filters.py:

from jinja2.\_compat import string\_types  
# Custom filter for use with Jinja2  
def natsort(arg):  
&nbsp;&nbsp;&nbsp;&nbsp;from natsort import natsorted  
&nbsp;&nbsp;&nbsp;&nbsp;return natsorted(arg)  
class FilterModule(object):  
&nbsp;&nbsp;&nbsp;&nbsp;def filters(self):  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;return {  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;'natsort': natsort  
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;}

and store it in your filters path (see 'ansible-config dump | grep  
DEFAULT\_FILTER\_PLUGIN\_PATH').

Now you can just use "{{ my\_version|natsort }}" which gives the order  
you're looking for.
