由于眼睛的问题,我不得不将控制台背景色改为白色,但字体是灰色的,它使消息无法阅读。我怎样才能改变呢?


当前回答

paint-console

简单的可着色原木。支持检查对象和单行更新 这个包只是重新油漆控制台。

安装

npm install paint-console

使用

require('paint-console');

console.info('console.info();');
console.warn('console.warn();');
console.error('console.error();');
console.log('console.log();');

我发现上面的答案(https://stackoverflow.com/a/41407246/4808079)非常有用,但不完整。如果你只想给某样东西上色一次,我想这没问题,但我认为以可运行的函数形式共享它更适用于现实生活中的用例。

const Color = {
  Reset: "\x1b[0m",
  Bright: "\x1b[1m",
  Dim: "\x1b[2m",
  Underscore: "\x1b[4m",
  Blink: "\x1b[5m",
  Reverse: "\x1b[7m",
  Hidden: "\x1b[8m",
  
  FgBlack: "\x1b[30m",
  FgRed: "\x1b[31m",
  FgGreen: "\x1b[32m",
  FgYellow: "\x1b[33m",
  FgBlue: "\x1b[34m",
  FgMagenta: "\x1b[35m",
  FgCyan: "\x1b[36m",
  FgWhite: "\x1b[37m",
  FgGray: "\x1b[90m",
  
  BgBlack: "\x1b[40m",
  BgRed: "\x1b[41m",
  BgGreen: "\x1b[42m",
  BgYellow: "\x1b[43m",
  BgBlue: "\x1b[44m",
  BgMagenta: "\x1b[45m",
  BgCyan: "\x1b[46m",
  BgWhite: "\x1b[47m"
  BgGray: "\x1b[100m",
}

function colorString(color, string) {
  return `${color}${string}${Color.Reset}`;
}

function colorLog(color, ...args) {
  console.log(...args.map(
   (it) => typeof it === "string" ? colorString(color, string) : it
  ));
}

像这样使用它:

colorLog(Color.FgYellow, "Some Yellow text to console log", { someObj: true });

console.log([
  colorString(Color.FgRed, "red"),
  colorString(Color.FgGreen, "green"),
  colorString(Color.FgBlue, "blue"),
].join(", "));

如果你想改变颜色直接自己没有模块尝试

console.log('\x1b[36m', 'sometext' ,'\x1b[0m');

先\x1b[36m改变颜色为36,然后回到终端颜色0。

下面是ANSI颜色代码列表

Reset: "\x1b[0m"
Bright: "\x1b[1m"
Dim: "\x1b[2m"
Underscore: "\x1b[4m"
Blink: "\x1b[5m"
Reverse: "\x1b[7m"
Hidden: "\x1b[8m"

FgBlack: "\x1b[30m"
FgRed: "\x1b[31m"
FgGreen: "\x1b[32m"
FgYellow: "\x1b[33m"
FgBlue: "\x1b[34m"
FgMagenta: "\x1b[35m"
FgCyan: "\x1b[36m"
FgWhite: "\x1b[37m"
FgGray: "\x1b[90m"

BgBlack: "\x1b[40m"
BgRed: "\x1b[41m"
BgGreen: "\x1b[42m"
BgYellow: "\x1b[43m"
BgBlue: "\x1b[44m"
BgMagenta: "\x1b[45m"
BgCyan: "\x1b[46m"
BgWhite: "\x1b[47m"
FgGray: "\x1b[100m"

例如,如果你想有一个昏暗的红色文本和蓝色背景,你可以在Javascript中这样做:

console.log("\x1b[2m", "\x1b[31m", "\x1b[44m", "Sample Text", "\x1b[0m");

颜色和效果的顺序似乎不是那么重要,但总是记得在最后重置颜色和效果。

var to_rgb = function (_text, _r, _g, _b) {
    return "\x1b[38;2;" + _r + ";" + _g + ";" + _b + "m" + _text + "\x1b[0m";
};

此代码帮助设置前景色:\x1b[38;2;R;G;Bm

这在某些地方可能行不通

我创建了自己的模块StyleMe。我这样做,我可以用很少的打字做很多事情。例子:

var StyleMe = require('styleme');
StyleMe.extend() // extend the string prototype

console.log("gre{Hello} blu{world}!".styleMe()) // Logs hello world! with 'hello' being green, and 'world' being blue with '!' being normal.

它也可以被嵌套:

console.log("This is normal red{this is red blu{this is blue} back to red}".styleMe())

或者,如果你不想扩展字符串原型,你可以选择其他3个选项:

console.log(styleme.red("a string"))
console.log("Hello, this is yellow text".yellow().end())
console.log(styleme.style("some text","red,bbl"))
