Node JS 统计代码数量_计数 nodejis

通过NodeJS统计静态文件的代码行数

Js代码如下：

let fs = require('fs')
let path = require('path')
 
 
// 获取命令行参数
let parm = process.argv.splice(2)
// 第一个参数是路径
let rootPath = parm[0]
// 后面的所有参数都是文件后缀
let types = parm.splice(1)
// 需要过滤的文件夹
//let filter = ['./node_modules']
let filter1 = "node_modules"
let filter2 = "test"
let filter3 = "lib"
let filter4 = "QModbusLib"
let filter5 = "Text"
let filter6 = "RemoteDataBroker"
let filter7 = "UITest"
// 需要过滤的文件
let filterFile1 = "system-keypad-config.j"
let filterFile2 = "qcustomplot."
let filterFile3 = "CSqlite."
//let filterFile4 = "qcustomplot."
 
// 统计结果
let num = 0
 
 
// 获取行数
async function line(path) {
    let rep = await fs.readFileSync(path)
    rep = rep.toString()
    let lines = rep.split('\n')
    if(lines.length > 1)
        console.log(path + ' ' + lines.length)
    num += lines.length
}
 
 
// 递归所有文件夹统计
async function start(pt) {
    let files = fs.readdirSync(pt)
    files.map(file => {
            return `${pt}/${file}`
        })
        .forEach(file => {
            let stat = fs.statSync(file)
            if (stat.isDirectory()) {
                if (file.indexOf(filter1) != -1 || file.indexOf(filter2) != -1 
                    || file.indexOf(filter3) != -1 || file.indexOf(filter4) != -1  
                    || file.indexOf(filter5) != -1 || file.indexOf(filter6) != -1 
                    || file.indexOf(filter7) != -1 ) {
                    return
                }
                start(file)
                return
            }
            if(file.indexOf(filterFile1) != -1 || file.indexOf(filterFile2) != -1
                || file.indexOf(filterFile3) != -1)
            {
                return
            }
            let ext = path.extname(file)
            if (types.indexOf(ext) != -1) {
                line(file)
            }
        })
}
 
 
;(async () => {
    await start(rootPath)
    console.log(`总代码行数：${num}`)
})()

调用js文件扫描文件

//                    <文件路径>  <文件类型>
