Line highlighting option

[Relequestual]

It looks like Carbon supports highligting individual lines: carbon-app/carbon#824 (comment)

Could this be added as a CLI option?

As stated by you here, adding it shouldn’t be a problem when it’s configurable via qs. 🙂 Doing it via Puppeteer would just be nasty imo. 😰

Right. I guess the first step is to try and make it part of the query string config... I'll take a look at that in the next few days and then come back!

carbon-app/carbon#806 has now been resolved and code can have font attributes changed including colour, however it doesn't add to the URL, which I believe is required for this to wrok?

So has this been implemented? How would you construct the command?

FWIW it's possible to use the sl query param like so: https://carbon.now.sh/?sl=3,5

This feature ships with the official v2 release. 🙂

Running carbon-now with --interactive will now yield additional questions regarding line highlighting.

And it will — as with all other options — lead to another setting inside your preset named selectedLines.

Assuming this code in a file unfold.js:

// Example from https://carbon.now.sh/
const unfold = (f, seed) => {
  const go = (f, seed, acc) => {
    const res = f(seed)
    return res ? go(f, res[1], acc.concat([res[0]])) : acc
  }
  return go(f, seed, [])
};

Running carbon-now unfold.js with a preset that has "selectedLines": "3,4,5,6" will lead to the expected result. 🙂

Hope that helps. 🙂

Happy testing and using! 🥳
