simple readdirp with filter and sync/async version

Features

• just traverse the file path, not the content of file
• readdirpSync for sync usecase

Usage

readdirpSync(dir, [filter])

sync to read the dir. the result is an array, which contains the file path(no filter param) or the filter return

• dir: the start directory, which will not include in the result
• filter: the filter function filter(filePath, stats).
  • filePath is the full path for the sub dir or file.
  • stats is the lstat return
  • the return value will be pushed at the result. if you return false, then this file will be ignored

readdirp(dir, filter, done)

async to read the dir.

• filter: filter(filePath, stats, [callback]).
  • callback: callback(err, ret). if no callback, then the return will be used in the result. otherwise, callback's ret parameter will be used in the result. if the ret param's value is false, the file will be ignored
• done: when finished, done is called. done(err, results)

8//read current directory's sub file relative path

13//ignore all directory, only its files
14var files = readdirpSync('.', function(filePath, stats){
15  if(stats.isDirectory()) return false;
16  return require('path').relative('.', filePath);
17});

19//async with no-callback filter: filter is sync
20readdirp('.', function(filePath, stats){
21  if(stats.isDirectory()) return false;
22  return require('path').relative('.', filePath);
23}, function(err, files){
24
25});
26
27//async with callback filter: filter is async
28readdirp('.', function(filePath, stats, cb){
29  if(stats.isDirectory()) cb(null, false);
30  else cb(null, require('path').relative('.', filePath));
31}, function(err, files){
