How to add copy button and linenums to a code block

[rcorre]

I can add linenums to a codeblock like this:

```py linenums="1"

I can add a copy button like this:

``` { .py .copy }

How can I have a copy button and linenums? I've tried all of the following, to no avail:

```{ .py .copy .linenums }
```{ .py .copy .linenums=1 }
```{ .py .copy .linenums="1" }
```{ .py .copy } linenums="1" 
```py copy linenums="1"

I don't want to enable a copy button globally, just on some blocks

Ah, I finally got it. It's { .py .copy linenums="1"} (no leading . for linenums)

Personally, I would try with this, but it has been a while since I've used it ✌️

```py { .copy linenums=1 }
```py linenums="1" { .copy }

By adding a dot . you set the class attribute, so the result was something like <code class="py copy linenums">, while we want the attribute <code class="language-python copy" linenums="1">

The { ... } is syntax from attr_list and it does apply custom data onto the previous Markdown element, which in this case is the code block.

Unfortunately neither of those work -- It seems you can't mix the leading py outside of the braces with other things in braces

This works for me:

```py {.copy linenums="1"}
import test
```
