Getting started


Easy to use, expressive API:

import Writer "mo:color/Writer";
import TextStyle "mo:color/TextStyle";

let { backgroundColor; textColor } = TextStyle;

let writer = Writer.Writer();

writer
  .text("hello world")
  .textColor(textColor.black)
  .backgroundColor(backgroundColor.white)
  .bold(true)
  .print();

Chain multiple colors on the same line:

...
import Debug "mo:base/Debug";

Debug.print(
  writer
    .text("It's easy being green")
    .textColor(textColor.green)
    .read()
  # ", however... " #
  writer
    .text("I really love purple backgrounds!")
    .backgroundColor(backgroundColor.purple)
    .read()
);

Use RGB colors for the text or background:

writer
  .text("woah dude, RGB!")
  .textColorRGB(20,40,60)
  .backgroundColorRGB(180,200,220)
  .print();

Immutable text styling settings, so use it all over the place, and don't worry about overwriting a bound setting.

let greenCheckMark = writer
  .text("✓")
  .textColor(textColor.green)
  .backgroundColor(backgroundColor.white);
let redCheckMark = greenCheckMark
  .textColor(textColor.red);

greenCheckMark.print();
redCheckMark.print();
