How to get a colorful terminal?

[dbssAlan]

hi,how can I achieve a similar effect?

or

I didn't find an API that can be set up quickly, and the theme in xterm doesn't seem to support such an effect? I tried writing some regular expressions. For example :

let regexp =
  /(?<!\\x1b\[[0-9;]*[a-zA-Z])\d+(?!\\x1b\[[0-9;]*[a-zA-Z])(?<!\\x)\d+(?!(b|B))(?<!\\x1b\[[0-9;]*)\d+(?![;m])/g;

let str =
  "This is 111 a 222te333st \x1b[0;233;255;1;34;333;3;32m123\x1b[0m 444 555st666ring777with \x1b[1;31m456\x1b[0m 9 99 num888bers 999";

let result = str.match(regexp)

console.log(result);


const numberColorful = (str) => str.replace(regexp , (str) => `\x1b[33m${str}\x1b[0m`);
……

this is done to match other numbers that are not in the ANSI. But it's too complicated, and the coverage and customization range aren't easy to adjust

It should meet your needs.

Maybe I misunderstood? xterm will connect to a terminal, and then this remote terminal will send some return values carrying ANSI to the frontend, and then the frontend will be displayed according to the corresponding color in the theme, so the front-end developer does not need to match and add ANSI?

[tisilent]

ye. You need to customize it or write it yourself just like the one you created above。

[dbssAlan]

So that means I have to match these strings myself and then add CSI?🤔

[tisilent]

I misunderstood...The description is incorrect.

[tisilent]

Xtermjs will help you parse.

Nope - xtermjs is a terminal in software, called a terminal emulator. It does not connect a terminal, it is the terminal. It connects to a TTY (a PTY in particular, which is a TTY for software terminals). There nothing like "ANSI forwarding".

Edit: What do you mean by "add ANSI"?

[dbssAlan]

"add ANSI" mean add CSI，Maybe I'm not saying it right

Edit: such as \x1b[31;1m

[jerch]

Ofc you have to add the needed terminal sequences yourself. How else should the terminal know, that you want a different color?

[dbssAlan]

Sorry, I confused terminal and tty

[tisilent]

I feel a bit dizzy...
Question: get color? ...

IOT developers are busy, and I'm not even sure if the device has a TTY to connect to. But this requirement needs to display a beautiful terminal, so I need to investigate first,

• if there is a TTY that can be connected, do I just need to set the theme of xterm?
• If it's a string sent to me, it seems like I'll need to do the segmentation match these strings myself and add CSI?

[tisilent]

Yes, if it's a string, you need to set it yourself.As @jerch said.

[tisilent]

The connection also depends on what TTY returns to you.

@dbssAlan
I think you should do 3 steps back and explain more in general, what you are trying to achieve here. Kinda both questions make not much sense...
