gradient-string

用於在終端打印出好看的漸變文字

• 普通用法

console.log(gradient('cyan', 'pink')('Hello world!'));

let a = 'so beautiful!'
let b = gradient('red', 'green');
console.log(b(a));

let c = gradient(['yellow', 'orange']);
console.log(c(a));

• 色值寫法能夠是各類形式

let coolGradient = gradient([
  tinycolor('#FFBB65'),       // tinycolor object
  {r: 0, g: 255, b: 0},       // RGB object
  {h: 240, s: 1, v: 1, a: 1}, // HSVa object
  'rgb(120, 120, 0)',         // RGB CSS string
  'gold'                      // named color
]);

• rainbaw 彩虹色🌈

console.log(gradient.rainbow('It\'s a rainbow!'))

• multiline 輸出文字量大，能夠保證文字垂直對齊

let arr = [
'   　｡*☆∴｡　｡∴☆*｡',
'    ｡★*ﾟﾟ*★∵★*ﾟﾟ*★｡',
'   ☆ﾟ　　 ﾟ☆ﾟ　　 ﾟ☆',
'   ★* ♡ I. ♡ *★  ',
'    ﾟ☆｡♥ LOVE. ♥ ｡ ☆ﾟ',
'    　*★｡♡F.C.F♡ ｡★*',
'    　 ∵☆｡　　｡☆∵',
'    　　ﾟ*★｡｡★*ﾟ',
'   　　 　ﾟ*☆  ', 
];
console.log(gradient('#fff', '#000').multiline(arr.join('\n')))

• 能夠設置從左到右的漸變百分比

let colorPool = gradient([
    {color:'#fff', pos: 0.1},
    {color:'red', pos: 0.7},
    {color:'yellow', pos: 1}
]);
console.log(colorPool.multiline(arr.join('\n')));

• 設置漸變方式

const redToGreen = gradient('red', 'green');
const str = '■'.repeat(48);
console.log(redToGreen(str)); 
console.log(redToGreen(str, {interpolation: 'hsv'}));
console.log(redToGreen(str, {interpolation: 'hsv', hsvSpin: 'long'}));
