K-Trainer

背景

有很多时候,我们需要手动的去完成一些任务显得很繁琐

例如

1. webpack生成完文件后,需要提交到内部机子上
2. 线上服务器不断的自动拉取master分支

找到了源代码,加以修改,然后原来忘记了开启webpack,然后又得cd到对应路径,然后webpack,再上传到内测机子

愿景

尽可能的减少不必要动作

ftp提交

1. 检查文件改动: 依赖https://www.npmjs.com/package/gaze
2. 查找sftp-config.json
3. 上传文件

查找了下,可以根据下面的库进行改造

经研究后,发现代码和思路与笔者不符,弃之

其余知识点

node命令行设置

我们如何通过命令行和nodejs文件交互?

建立处理命令行文件,

#!/usr/bin/env node
console.log('hello world');

给予权限

chmod 755 文件名

这时就可以进行交互了,当时命令没有在全局里,需要npm link

在执行命令前需要修改package.json

  "bin": {
    "命令名称": ".文件路径"
  },

获取参数

通过process.argv

//console.log('hello world1',process.argv);
  ~ / k_trainer asdas
hello world1 [ '/usr/local/bin/node', '/usr/local/bin/k_trainer', 'asdas' ]

中途折腾点

文件更改监听

var fs = require('fs');

fs.watch('./*', {encoding: 'buffer'}, (eventType, filename) => {
    console.log(filename);
    console.log(eventType);
});

这个方法注意点有

1. 不支持子目录监听
2. 当新建目录或文件时,eventType为rname

安装lftp失败

错误信息

 ~/Downloads/lftp-4.7.5   brew install lftp
==> Downloading http://lftp.yar.ru/ftp/lftp-4.6.0.tar.gz

一开始我以为我以前把brew的源切换了,然后验证了下

down vote
cd `brew --prefix`
git remote -v

 /usr/local  master ✔  git remote -v
origin    https://github.com/Homebrew/homebrew (fetch)
origin    https://github.com/Homebrew/homebrew (push)

结构发现并没有,后来发现可能是brew太旧的原因

于是brew update,但是还是不行

Checking out v1.0.1 in /usr/local/Homebrew...
To checkout v1.0.1 in /usr/local/Homebrew run:
  'cd /usr/local/Homebrew && git checkout v1.0.1
Error: No available formula with the name "lftp"

This similarly named formula was found:

To install it, run:
  brew install homebrew/x11/curlftpfs ✔

然后根据http://stackoverflow.com/questions/39633159/homebrew-cant-find-lftp-formula-on-macos-sierra,进行`brew install homebrew/boneyard/lftp`,但还是安装失败

最后找到这个pkg,然后安装...
