'use strict';

const fs = require('fs');

module.exports = (path, solver) => {
  fs.readdir(path, (err, childs) => {
    let prom = childs.map((child) => {
      return new Promise((r, j) => {
        fs.stat(`${path}/${child}`, (err, stats) => {
          if (stats.isDirectory()){
            walk(`${path}/${child}`, (sub) => {
              if (sub.length == 0)
                r({path: `${path}/${child}`});
              else
                r({path: `${path}/${child}`, childs: sub});
            });
          } else {
            r({path: `${path}/${child}`});
          }
        });//End stat
      });//End promise
    });//End map
    Promise.all(prom).then((childs) => {
      solver(childs);
    });
  });//End readdir
};
