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"))
