DocGen Copy button for code snippets

[ringabout]

Would be great to add a "Copy" button to the code blocks rendered by the Docgen,
just like GitHub itself has nowadays on the code blocks, the Docgen needs to add 1 line:

<button onclick="document.querySelector('#SELECTOR').select();document.execCommand('copy');">Copy</button>

I would like to contribute to this awesome project. Would you guide me on which file should I change?

Here is my quick prototype

Hi @vj-abishek

You may start from here:

Nim/compiler/docgen.nim

Line 617 in 6b0db5b

proc getAllRunnableExamplesImpl(d: PDoc; n: PNode, dest: var ItemPre,

Nim/lib/packages/docutils/rstgen.nim

Line 1034 in 6b0db5b

proc renderCode(d: PDoc, n: PRstNode, result: var string) =

https://github.com/nim-lang/Nim/blob/devel/tools/dochack/dochack.nim

After fixing the file, you can use koch temp doc -r ... to test whether the fix works.

I'm getting this error.
How to run locally

[ringabout]

What's your command? Does /home/abishek/opensource.nim exist? How about putting the file under /Nim directory?

[vj-abishek]

I ran ./koch temp doc -r ..
When I run koch temp doc -r .. it says command not exists

Does /home/abishek/opensource.nim exist?

No

How about putting the file under /Nim directory?

The dir structure is /home/abishek/opensource/Nim

Any documentation available on how to run locally. That docs page

I ran ./koch temp doc -r ..

Well, I mean ./koch temp doc -r yourdocfile.nim 😄
