Spinny

Spinny is a tiny terminal spinner package for Nim Programming Language.

Getting Started

You can use Nimble to install the package by running:

nimble install spinny

This library uses threads for spinners, so you have to compile your application(or add to your nim.cfg):

--threads:on

Usage

Spinny is quite easy to use. You can set the color, text or symbol of an already running spinner.

import spinny, os

var spinner1 = newSpinny("Loading file..".fgWhite, Dots)
spinner1.setSymbolColor(fgBlue)
spinner1.start()

# do some work here
for x in countup(5, 10):
  sleep(500)

spinner1.success("File was loaded successfully.")

var spinner2 = newSpinny("Downloading files..".fgBlue, Dots5)
spinner2.setSymbolColor(fgLightBlue)
spinner2.start()

# do some work here
for x in countup(5, 10):
  sleep(500)

spinner2.error("Sorry, something went wrong during downloading!")

You can even use custom spinners if predefined ones aren't suitable for your needs.

import spinny, os

# makeSpinner accepts two arguments - the interval between different frames,
# and frames themselves (as a sequence of strings)
var spinner3 = newSpinny("I'm custom.", makeSpinner(100, @["x", "y"]))
spinner3.setSymbolColor(fgGreen)
spinner3.start()

# do some magnificent work here
for x in countup(1, 5):
  sleep(500)

spinner3.success("Looks like it's working!")

Spinny embeds the colorize library for terminal colors.For spinners to use, take a look at the src/spinners.nim file. (Credit goes to sindresorhus)
