looking for help in building the console application with syntax highlight about readline-sync HOT 9 CLOSED

Hi @dineshkumar02, thank you for the comment.
Sorry, my English is poor.
What is the keystore?
Do you mean that you want to add colors in the terminal window?

Hi @anseki ,

I am sorry for the typo in my question.

I mean, whenever a user press a KEY on the keyboard(This is what keystroke) .

A simple readline example here.

  process.stdin.on("keypress", (c, k) => {
   if (k.name=='space'||k.name=='tab') {
    // setTimeout is needed otherwise if you call console.log
    // it will include the prompt in the output
    setTimeout(() => {
      **rl._refreshLine();**
   }, 1);
  } else if(k.name=='c' && k.ctrl) {
    console.log('\nbye');
    exit();
  }
  });

  rl._writeToOutput = function _writeToOutput(stringToWrite) {
    **rl.output.write(highlight(stringToWrite, { language: "html" }));**
  };

Here, whenever the user types the HTML tags, We use highlightjs to process it, and print the color.
But, we are doing this for every KEYPRESS, which is refreshing the entire line.

Shall we achieve the syntax highlight, whenever the user type the command, which is something like "fishshell" (https://fishshell.com/).

Thanks in advance for your help.

Umm...
Sorry, I couldn't understand the topic.
Your example seems to be not using readlineSync. The rl has methods that I don't know.
Maybe, you are talking about "readline", not "readlineSync".
I am sorry that I could not be of any help to you.

Hi @anseki ,

I am sorry, let me put my question in this way.

By using readline-sync, shall we achieve the syntax color.
For example, in prompt user actually types the HTML code. Whenever he types the html code, we have to give the color.

Prompt> "< some tag > < / some tag > " ---This what user types in the prompt, and we have to give the syntax highlight instantly

Do you mean that you want to add the syntax highlight (e.g. colors) before user pressing Enter key?

Yes @anseki,

Exactly, before pressing the enter we want to have the syntax highlight(colors).

You seem to be making TUI app. Then, you need TUI library, not CUI (CLI) library such as readlineSync.
In CUI (CLI), the "readline" reads a line via TTY. That is, the line is made by Enter key.
Therefore, readlineSync is not required for your app.
For example, Vim text editor that is very famous TUI app supports the syntax-highlight with TUI base library.

Thanks @anseki,

I will take your suggestions, and will look for the TUI libraries.
