example

getTimeString(type)

const { getTimeString } = require('slimz');
getTimeString(type)

mkdir(dir)

const { mkdir } = require('slimz');

mkdir('./a').then(()=>{
	return mkdir('a/b')
}).then(()=>{

}).catch(err=>{
	console.log(err)
})

exists(filePath)

exists('package.json').then(data=>{
	console.log(data)
})

exec_cmd(linx_cmd)

exec_cmd(`ls -al > a.txt`,()=>{
   console.log("finish")
}).then((data)=>{
    console.log(data)
})

getFileList(options)

options<Object>

• folder: The path of the folder
• skip: The folder you want to skip, it must be an Array
• ext: Filter the extension, it must be an Array

example:

const options={
  folder: path.resolve(__dirname),
  skip:['node_modules/slimz','node_modules/fs-extra'],
  ext:['md']
}

getFileList(options).then(data=>{
  console.log(data)
}).catch(err=>{
  console.log(err);
})
//also you can do like this:
const { getFileList } = require('slimz')
async function run(){
  const options = {
    folder:"/Volumes/datavolumn_bmkserver_Pub/新做稿",
    skip:['摄影'],
    ext:['xls','xlsx']
  }
  let files = await getFileList(options)
  console.log(files)
}
run()
