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?

内联typescript解决方案
export const color = (function (colors) {
const fn = (code: number, str: string) => `\x1b[${code}m${str}\x1b[39m`;
const obj = { grey: fn.bind(null, 90) };
for (let i = 0; i < colors.length; i++) obj[colors[i]] = fn.bind(null, 30 + i);
return obj as { [K in typeof colors[any] | 'grey']: (str: string) => string };
})(['black', 'red', 'green', 'yellow', 'blue', 'magenta', 'cyan', 'white'] as const);

var colorSet = {
Reset: "\x1b[0m",
Red: "\x1b[31m",
Green: "\x1b[32m",
Yellow: "\x1b[33m",
Blue: "\x1b[34m",
Magenta: "\x1b[35m"
};
var funcNames = ["info", "log", "warn", "error"];
var colors = [colorSet.Green, colorSet.Blue, colorSet.Yellow, colorSet.Red];
for (var i = 0; i < funcNames.length; i++) {
let funcName = funcNames[i];
let color = colors[i];
let oldFunc = console[funcName];
console[funcName] = function () {
var args = Array.prototype.slice.call(arguments);
if (args.length) {
args = [color + args[0]].concat(args.slice(1), colorSet.Reset);
}
oldFunc.apply(null, args);
};
}
// Test:
console.info("Info is green.");
console.log("Log is blue.");
console.warn("Warn is orange.");
console.error("Error is red.");
console.info("--------------------");
console.info("Formatting works as well. The number = %d", 123);
我为不能有依赖的npm脚本写了一个方便的一行代码:
Const {r, g, b, w, c, m, y, k} = [ ['r', 1], ['g', 2], ['b', 4], ['w', 7], ['c', 6], ['m', 5], ['y', 3], ['k', 0], ].Reduce ((cols, col) => ({ ...关口,[坳[0]]:f = > ' \ x1b[3{坳[1]}美元$ {f} \ x1b [0 m ' }, {}) console.log(' ${g('I')} love ${r('Italy')} ')
R,g,b,w,c,m,y,k分别代表红色,绿色,蓝色,白色,青色,品红,黄色和黑色。
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"))
你可以使用下面的例子: https://help.ubuntu.com/community/CustomizingBashPrompt
也是nodeJs的一个要旨
例如,如果你想让部分文本显示为红色,只需执行console.log with:
"\033[31m this will be red \033[91m and this will be normal"
基于此,我为Node.js创建了“colog”扩展。你可以使用以下方法安装:
npm install colog
回购和npm: https://github.com/dariuszp/colog
下面你可以找到运行node.js应用程序时文本的颜色引用:
console.log('\x1b[36m%s\x1b[0m', 'I am cyan'); //cyan
console.log('\x1b[33m%s\x1b[0m', stringToMakeYellow); //yellow
注意%s是字符串(第二个参数)被注入的位置。\x1b[0m重置终端颜色,因此在此之后它不再继续是所选的颜色。
颜色参考
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"
编辑:
例如,\x1b[31m是一个转义序列,它将被您的终端拦截,并指示它切换到红色。事实上,\x1b是不可打印控制字符转义的代码。仅处理颜色和样式的转义序列也被称为ANSI转义代码,并且是标准化的,因此它们(应该)适用于任何平台。
维基百科对不同终端显示颜色的方式做了很好的比较 https://en.wikipedia.org/wiki/ANSI_escape_code#Colors
