Usage

0. walkdir

EFDIR# node
> efdir = require("./efdir.js")
>
> var arr = efdir.walkdir("../EFDIR")
undefined
> arr
[ '/opt/JS/EFDIR/LICENSE',
  '/opt/JS/EFDIR/README.md',
  '/opt/JS/EFDIR/efdir.js',
  '/opt/JS/EFDIR/node_modules/abbrev/LICENSE'
  ....
]

1. with filter

> var efdir = require("./efdir.js")
undefined
> var arr = efdir.walkdir("../EFDIR","only-dir")
undefined
> arr
[ '/opt/JS/EFDIR',
  '/opt/JS/EFDIR/node_modules',
  '/opt/JS/EFDIR/node_modules/.bin',
  '/opt/JS/EFDIR/node_modules/abbrev',
  '/opt/JS/EFDIR/node_modules/balanced-match',
  ......
]


> var arr = efdir.walkdir("../EFDIR",function(r){
...     return(r.includes("realpath"))
... })
undefined
> arr
[ '/opt/JS/EFDIR/node_modules/fs.realpath',
  '/opt/JS/EFDIR/node_modules/fs.realpath/LICENSE',
  '/opt/JS/EFDIR/node_modules/fs.realpath/README.md',
  '/opt/JS/EFDIR/node_modules/fs.realpath/index.js',
  '/opt/JS/EFDIR/node_modules/fs.realpath/old.js',
  '/opt/JS/EFDIR/node_modules/fs.realpath/package.json' ]
>


    > efdir.WALK_FILTERS
    { 'no-dot-files': [Function: no-dot-files],
      none: [Function: none],
      'only-dot-files': [Function: only-dot-files],
      'only-dir': [Function: only-dir],
      'only-file': [Function: only-file] }
    >

2. with depth range

> var efdir = require("./efdir.js")
undefined
> var arr = efdir.walkDirInRange("../EFDIR",{start:0,end:2})
undefined
> arr
[ '/opt/JS/EFDIR/LICENSE',
  '/opt/JS/EFDIR/README.md',
  '/opt/JS/EFDIR/efdir.js',
  '/opt/JS/EFDIR/package.json' ]
>

3. transcodec

var src_str = "你们好"
var dst_str = efdir.transcodec(src_str,'utf8','latin1')
> efdir.transcodec(dst_str,'latin1','utf8')
'你们好'
>

4. rfile and wfile

> str_latin1 = efdir.rfile('txt','latin1')
'å�¤æ�æ�¯ä¸�æ�¯æ��ä»¶å¤¹\n'
efdir.wfile('txt.latin1',str_latin1,'latin1')
> efdir.rfile('txt.latin1','utf8')
'判断是不是文件夹\n'
efdir.rfile('txt','utf8')

5. mkdirp_and_touch

> efidr.mkdirp_and_touch('a/b/c')
[ 'a', 'a/b', 'a/b/c' ]
>
EFDIR# tree a
a
└── b
    └── c                //file

1 directory, 1 file
EFDIR#



> efdir.mkdirp_and_touch('d/e/f/')              //last end with '/'
[ 'd', 'd/e', 'd/e/f', 'd/e/f.dir/' ]
>
EFDIR# tree d
d
└── e
    └── f                  //dir

2 directories, 0 files

6. dict_to_pl$entries

    var efdir = require('efdir')
    var j =     {
         'CHANGELOG.md': '',
         'LICENSE': '',
         'README.md': '',

         'package.json': '',
         'range.bnf': '',
         'semver.js': ''
        }
    efdir.dict_to_pl$entries(j,'./')
    > efdir.dict_to_pl$entries(j,'./')
    [
      [ '/opt/JS/EFDIR', {} ],
