  v install tobealive.bartender
  

  import tobealive.bartender
  

Usage examples

• Simple bars

  // Default bar
  mut b := Bar{}
  for _ in 0 .. b.iters {
   	b.progress()
  }
  
  // Customized bar
  mut b2 := Bar{
  	width: 60
  	runes: BarRunes{
  		progress: `#`
   		indicator: `❯`
  		remaining: `-`
  	}
  	pre: '|'
  	post: Affix{
  		pending: '| Loading...'
  		finished: '| Done!'
  	}
  }
  for _ in 0 .. b2.iters {
   	b2.progress()
  }
  

• Smooth bar themes

  mut b := SmoothBar{
  	theme: Theme.pull // Default = Theme.push
  }
  for _ in 0 .. b.iters {
  	b.progress()
  }
  
  b2 = SmoothBar{
  	theme: ThemeVariant{.pull, .drain}
  }
  for _ in 0 .. b2.iters {
  	b2.progress()
  }
  
  // Customized smooth bar
  mut b3 := SmoothBar{
  	theme: Theme.split
  	width: 80
  	pre: '│'
  	post: fn (b SmoothBar) (string, string) {
  		return '│ Saving... ${b.pct()}% ${term.blue(b.eta(20))}', '│ Saved!'
  	}
  }
  b3.colorize(.cyan)
  for _ in 0 .. b3.iters {
  	b3.progress()
  }
  

• Bar Reader for io operations.

  // Returns an `io.BufferedReader` that displays a progressing bar when used in a reader operation.
  pub fn (b Bar) reader(reader io.Reader, size u64) &io.BufferedReader
  

  mut src_file := os.open(src_file_path)!
  mut dst_file := os.create(dst_file_path)!
  
  bar := bartender.Bar{}
  mut bar_reader := bar.reader(src_file, os.file_size(src_file_path))
  io.cp(mut bar_reader, mut dst_file)!

Showcase

Disclaimer

Until a stable version 1.0 is available, new features will be introduced, existing ones may change, or breaking changes may occur in minor(0.<minor>.*) versions.

Outlook

Below are some of the things to look forward to.

• Reader Interface
• Multiline (Smooth Bar Split Themes are not supported yet)
• Time Remaining
• Dynamic adjustment on term resize for all variants (basic width detection works)
• Extend visuals & customizability
