Support "process.stdout.write" in logging

[spidy0x0]

Hi, i love this project and i wanted to suggest a feature .

i normally use this code to update figures/values on the same line without creating newlines.
just like console.log,but it doesn't create a newline always.
Example is when creating a countdown/timer in the terminal.

process.stdout.write(`${currentTime}\r`)

and it works perfectly.
But when i add it to the chalk-animation syntax like

chalkAnimation.rainbow(process.stdout.write(`${currentTime}\r`));

i get this error

.../node_modules/chalk-animation/index.js:134
		text: str.split(/\r\n|\r|\n/),
		          ^

TypeError: str.split is not a function

Is there any way to do this?
Thanks

Hi !

You can replace the text of an animation that has already started.

For example, you can add a dot every second like this :

let str = 'Loading...';
const rainbow = chalkAnimation.rainbow(str); 
setInterval(() => { 	rainbow.replace(str += '.'); }, 1000);

(sorry about formatting, I'm on mobile)

hi, i tried doing this

        let left = hours + ":" + minutes + ":" + seconds ;

        const rainbow = chalkAnimation.rainbow(left); 
        setInterval(() => { 	rainbow.replace(left); }, 1000);

but it keep logging on a new line always

and i want the countdown on a single line

Hi,

There is not need to do a PR that changes the whole thing, just use .replace() as I told you before !

For example, here is what I can achieve with the following code:

// server.js
import chalkAnimation from 'chalk-animation';

let seconds = 43;

let left = '06:00:' + seconds;

const rainbow = chalkAnimation.rainbow(left);
setInterval(() => {
  seconds = seconds - 1;
  left = '06:00:' + seconds;
  rainbow.replace(left);
}, 1000);

hi, i tried what you suggested and it wasn't working. I waited for hours for a working example but you weren't available.
So i had to find a workaround.
Thanks for the POC buddy

Yeah sorry I'm usually away from my computer on weekends.

Is the last example working for you?
