node-walk

A not-quite-port of python's os.walk.

Installation

npm install walk

Usage

var walk = require('walk'),
  options = {
    followlinks: false,
    topdown: false, // currently ignored
  };

function fileHandler(err, path, nodes, sorted) {
  // handle each path  
}

walk("path/to/dir", options, fileHandler);
// This also works
// walk("path/to/dir", options).whenever(fileHandler);

• err - Probably can't read a directory due to permissions.
• path - the current path being read
• nodes - an array of stats
• sorted - nodes sorted by type
  • errors - nodes that could not be stated and why
  • files - actual files (or links when followlinks is true)
  • dirs - directories
  • blocks - block devices
  • chars - character devices
  • links - symbolic links
  • fifos - FIFOs
  • sockets - sockets

Example

mkdir -p walk-test/dir1
touch walk-test/file-1
touch walk-test/file-2
touch walk-test/dir1/file-1
touch walk-test/dir1/file-2

node-walk-test

var walk = require('walk');

walk('./walk-test', undefined,  function (err, path, nodes, sorted) {
  if (err) {
    console.log('ERROR: ');
    console.log(err);
    return;
  }
  o.dirs.forEach(function (item, i, arr) {
    if (item.name.match(/trash/i)) {
      console.log('found a trash');
      arr.splice(i,1);
    }
  });
  console.log("PATH: " + path);
  console.log("SORTED: ");
  console.log(o);
});
