code block: is it possible to enable copy, without line numbers?

[aborruso]

Hi,
if I use simply

```
sed -r 's/^.+=//g;s/,\];/]/g'
```

I have no line numbers and no copy block.

If I add {.txt}, I have both line numbers and copy button.

```{.txt}
sed -r 's/^.+=//g;s/,\];/]/g'
```

Is there a way to have copy button, and no line numbers?

I have tried {.txt line_numbers=false}, but I have always the line number.

Thank you

Yes, try this:

---
format: 
  revealjs:
    code-line-numbers: false
    code-copy: false
---

Thank you @jjallaire, this is not what I want. I explained myself badly, sorry

My goal is to have by default line numbers and code-copy, and to be able to choose to have in example only in one block code the code copy, but not the line number.

You can do this:

```{.txt code-line-numbers="false"}
sed -r 's/^.+=//g;s/,\];/]/g'
```
