index template function

[endorama]

Hello, I spent some time understanding how to extract the element at index n of an Array

Es:

arr := [1,2,3]
I want to get arr[1] => 2

I finally found the index function, but is not documented in the docs and I did't find it's declaration in the code.

The usage is

{{ index arr 2 }}

and I found references in:

• list_test.go
• string_test.go

Where does it come from? Should be documented in the list.md doc file?

I'm sorry if it's something obvious, I'm new to go and sprig. I can provide a PR to the documentation if you point me in the right direction.

Thank you!

@endorama The index function isn't part of sprig. Rather, it's part of the go templating functions. The following link has more details - https://golang.org/pkg/text/template/#hdr-Functions. That's why we don't document it here.

If you have further questions please feel free to re-open the issue.

@mattfarina Thank you!! It's all clear now. And thanks for the link to the docs, I did find that page but obviously missed/misunderstood that part.
