About

A visual CLI change/progress indicator

Why

When you save a file and your watcher rebuilds your project it is sometimes hard to see that anything has changed because the output from the watch process is so similar to the previous output.

For who?

CLI applications.

How

cli-color

API

var progressBox = require( 'cli-progress-box' )

var opts = {} // state object ( mutates )
var box = progressBox( opts ) // create new progress box

box.tick() // alias for box()
box.redraw() // shorthand for `box.clc.reset + box.tick()`

box.clc // embedded `medikoo/cli-color` object

box.bgColors.dark // list of `medikoo/cli-color` bacground colors
box.bgColors.bright // list of bright `medikoo/cli-color` background colors
box.bgColors.all // both lists

box.fgColors.dark // list of `medikoo/cli-color` bacground colors
box.fgColors.bright // list of bright `medikoo/cli-color` background colors
box.fgColors.all // both lists
