How to show progress bar in one line when using for loop ?

[amrsa1]

I have a function where im looping over an array, to do some process this lead to see progress bar appearing in many line rather than show the progress on the same bar.

Could you provide an example how to do so when im using for loop

const bar = new cliProgress.SingleBar({
      format: 'Processing |' + chalk.cyan('{bar}') + '| {percentage}% || {value}/{total} Pages || Current File: {filename}',
      barCompleteChar: '\u2588',
      barIncompleteChar: '\u2591',
      hideCursor: true
    }, cliProgress.Presets.shades_classic);

    bar.start(pages.length, 0, {
      filename: 'Starting...'
    });

    for (const page of pages) {
      const pageName = page.FileLeafRef;

      // Update the progress bar with the current file name and progress
      bar.increment(1, {
        filename: pageName
      });

      const pageContent = page.CanvasContent1;

      if (pageContent) {
        const cleanedContent = cleanHtml(decodedContent);
        const outputPdfPath = `./${path.parse(pageName).name}.pdf`;
        await convertHtmlToPdf(cleanedContent, outputPdfPath);
      } else {
        console.log(chalk.red(`Failed to retrieve content for page: ${pageName}\n`));
      }

Hi, did you find a fix for this issue? I'm currently running into the same thing. Thanks.

mostly caused by some logs/stdout/stderr writes

I have successfully used this approach to monkeypatch in logging for SingleBar.

// Initialize progress bar
const bar = new cliProgress.SingleBar({
  format: "🧪 Testing pages [{bar}] {percentage}% | {value}/{total} | ETA: {eta}s | {file}",
});

bar.loggingBuffer = [];
bar.log = function (message) {
  bar.loggingBuffer.push(message);
};
bar.on("redraw-pre", (data) => {
  if (bar.loggingBuffer.length > 0) {
    bar.terminal.clearLine();
    bar.terminal.cursorTo(0);
    while (bar.loggingBuffer.length > 0) {
      bar.terminal.write(bar.loggingBuffer.shift());
      bar.terminal.write("\n");
    }
  }
});

Stole the idea from the current implementation in MultiBar:

cli-progress/lib/multi-bar.js

Line 246 in e2347a3

log(s){

Also, please note I do not know the best practices for monkey patching so there's probably some obvious improvement possible here.
