What does this package do?

This package introduces ultra-customizeable terminal-based progress bars for Arturo. Simply put, whether you want to track the progress through an iteration or create a custom progress bar and play with it yourself, it's supported.

How do I use it?

First import it and then... let's decide how you want to use it.

With iterators

Do you want to use it along with an existing iterator? That's very easy:

import "progressive"!

progressive\loop 1..20 'x [
    processing ~"Current num: |x|"
    pause 200
]

Important
Right now, Progressive supports the following Iterator "overloads":

• loop
• map
• select
• filter

Tip
Want to process items concurrently? Just add .parallel (or .parallel: N, to cap the number of items in flight) - e.g. progressive\map.parallel urls 'u [ ... ]. The progress bar will keep track of completed items, as they finish. (Requires a recent - nightly - build of Arturo and a single iteration parameter, e.g. 'x)

Tip
By calling the magic function processing from inside a progressive iterator, you may pass information which will be displayed above the progress bar (as in: "what is currently being processed?")

Custom progress bars

If you want to create a progress bar object and manipulate it yourself, that's possible too:

import "progressive"!

i: 0
limit: 20
progress: progressive\new limit!

while [i < 20][
    progress\increase 1
    pause 200
    i: i + 1
]

Option Reference

Progressive comes with lots of different options so that you are able to customize your progress bars to your heart's content!

Styles

Common options

More customization

Tip
You may pass any combination of the options above (= that's a lot!) either to an iterator, or when creating a new custom progress bar.
So, this:

progressive\loop .fancy .label:"Doing sth" ...

...is perfectly valid!
