progressbar

A simple console progress bar. Progress bar writing now runs on another thread.

Do not use Consolas or Andale Mono for terminal font because the box-drawing glyphs in these fonts are not aligned properly. Menlo, Fira Mono, Source Code Pro or SF Mono are recommended for optimal visual effects.

Maven:

    <dependency>
      <groupId>me.tongfei</groupId>
      <artifactId>progressbar</artifactId>
      <version>0.5.0</version>
    </dependency>

Usage:

ProgressBar pb = new ProgressBar("Test", 100);
pb.start(); // the progress bar starts timing
some loop {
  ...
  pb.step(); // step by 1
  pb.stepBy(n); // step by n
  ...
  pb.stepTo(n); // step directly to n
  ...
  pb.maxHint(n);
  // reset the max of this progress bar as n. This may be useful when the program
  // gets new information about the current progress.
  ...
  pb.setExtraMessage("Reading..."); // Set extra message to display at the end of the bar
}
pb.stop() // stops the progress bar
