demo gif

Just wrap the SequenceType in your loop with the Progress SequenceType and you'll automatically get beautiful progress bars.

Updating the progress bar does not work in the Xcode console because it does not support the cursor movements. If you want it to look nice run it in a real terminal.

Example

Just take a regular loop like this for i in 1...9 { ... and wrap the 1...9 range in the Progress type and you'll automatically get a nice progress bar.

import Progress

for i in Progress(1...9) {
    ...
}

Creates this output:

$ 4 of 9 [-------------                 ] ETA: 0:00:05 (at 1.01 it/s)

It also works with all the other types adopting the CollectionType protocol like dictionarys: Progress(["key": "value", "key2": "also value"]) and arrays: Progress([1, 52, 6, 26, 1]).

You can also create the progress bar manually without a sequence type:

var bar = ProgressBar(count: 4)

for i in 0...3 {
    bar.next()
    sleep(1)
}

Configuration

You can configure the progress bar by combining single building blocks of type ProgressElementType.

Either by setting a default configuration:

ProgressBar.defaultConfiguration = [ProgressString(string: "Percent done:"), ProgressPercent()]

which creates the following result:

$ Percent done: 80%

or by providing a specific configuration in the Process initializer:

Progress(0...10, configuration: [ProgressPercent(), ProgressBarLine(barLength: 60)])

resulting in something like this:

$ 100% [------------------------------------------------------------]

Available ProgressElementType elements:

  • ProgressBarLine (The actual bar. E.g. "[---------------------- ]").
  • ProgressIndex (The current index & overall count. E.g. "2 of 3").
  • ProgressPercent (The progress in percent. E.g. "60%").
  • ProgressTimeEstimates (Estimated time remaining & items per second. E.g. "ETA: 00:00:02 (at 1.00 it/s)").
  • ProgressString (Adds an arbitrary string to the progress bar).
