Sorting in advanced way

[lee1043]

In the interactive portrait plot, would it be available to add below function replacing the python’s default sorting?

import copy
import re

def sort_human(input_list):
    l = copy.copy(input_list)
    convert = lambda text: float(text) if text.isdigit() else text
    alphanum = lambda key: [ convert(c) for c in re.split('([-+]?[0-9]*\.?[0-9]*)', key) ]
    l.sort( key=alphanum )
    return l

Above function is what that I have used for creating my own portrait plot before your modal capability has become available. It sorts labels more in recognizable way.

For example, default sorted sorts as below:
A_r10i1p1
A_r1i1p1
A_r20i1p1
A_r2i1p1
A_r3i1p1

And the function I implemented sorts as below:
A_r1i1p1
A_r2i1p1
A_r3i1p1
A_r10i1p1
A_r20i1p1

I guess the right place might be in click/click_plots/portrait_plots.py, line 174 and 176 where sorted has been used, but would be nicer if you could confirm this for me.

Below is for actual use example.

>>> a=['a_1', 'a_11', 'a_2']
>>> sorted(a)
['a_1', 'a_11', 'a_2']

>>> import copy
>>> import re
>>> def sort_human(input_list):
...     l = copy.copy(input_list)
...     convert = lambda text: float(text) if text.isdigit() else text
...     alphanum = lambda key: [ convert(c) for c in re.split('([-+]?[0-9]*\.?[0-9]*)', key) ]
...     l.sort( key=alphanum )
...     return l
>>> sort_human(a)
['a_1', 'a_2', 'a_11']
>>>

@lee1043 thanks for this, I have always disliked the python default sorting, the example above is certainly more preferable - it'd be a great function to have in a general library

@durack1 agreed. @lee1043 I'll add it in click plots for sure, would you mind linking to this issue from genutil please. I think as @durack1 mentioned that's where it belongs.
