Add a filter that returns an array element by index

[hatifnatt]

In Django template It's tricky to access specific array element by index if array is obtained as the result of applying a filter, because it's impossible to directly use index after filter.
I.e. I want only third part of the path

data = /first/second/third/fourth
data|split:'/'|slice:'2:3'|join:''

not very clear and intuitive, slice with single element still returns an array.

Better with custom JS filter, but not very portable, you need to supply your custom filter with your template:

In[Param];

data|split:'/'|index:'2'

In Jinja2 element can be easily accessed by index or slice can be taken without additional filters:

data|split('/')[2]

Go template has an index function.

I added an index filter.

{{ "/home/user/test" | split:"/" | index:"1" }}

You can also use negative indexes like in python for example.
