How to add copy button to the code block without using macro?

how to Add copy button to the top right.

I find a way by macro:

But I already add many code snippets to my tw. I don’t want to change them to macro one by one. So is there a way to change them from global?

If this possibility would exist, we would have used it at tiddlywiki.com already.

Okay I don’t realize this function that hard.

It’s not hard. … It’s just nobody did it, because we have a working solution using macros.

I try copy-to-clipboard to copy my code block, seems not that great.

If I want to copy the multiline code better to write it into the “myCode” tid.
So my macro will be.

<$macrocall $name="copy-to-clipboard" src={{myCode}}/>

But you can’t add

`` `

`` `

into the myCode.tid since you don’t want to copy the code block mark.

If you don’t add the ``` the code will lose the highlight…

Add code twice one for plain, one for highlight will solve this problem, but not that graceful.
