You can use Nodejs to write a simple command line tool yourself. You only need to master the simple synchronization file module and regular expressions~
var fs = require("fs")
function format(filePath, keywords) {
// 同步读取文件内容
var content = fs.readFileSync(filePath, "utf-8")
var arr = content.split("\n")
var count = 0
for (var i = 0; i < arr.length; i++) {
var value = arr[i]
var temp
temp = value.replace(/(\d+)px/g, function() {
if (arguments[3].indexOf("@media") != -1 || arguments[3].indexOf("max") != -1 || arguments[3].indexOf("min") != -1) {
} else if (Number(arguments[1]) > 1) {
count++;
// 这里可以自己维护换算规则
return Number(arguments[1]) / 100 + "rem"
}
return arguments[0]
})
if (temp != arr[i]) {
arr.splice(i + 1, 0, temp)
}
}
var result = arr.join("\n")
var formatFilePath = filePath.replace(".", keywords + ".");
fs.writeFile(formatFilePath, result, "utf-8", function(err) {
if (err) console.log(err)
console.log("change lines number: " + count)
})
}
format("style.css", "_format");
Use node app.js (for example, you save the above code as app.js) Then it will automatically calculate the style.css in the same path and calculate the px in it as rem. You can maintain it yourself. Conversion rules.
