+# recursive-readdir
+
+[![Build Status](https://travis-ci.org/jergason/recursive-readdir.svg?branch=master)](https://travis-ci.org/jergason/recursive-readdir)
+
+Recursively list all files in a directory and its subdirectories. It does not list the directories themselves.
+
+Because it uses fs.readdir, which calls [readdir](http://linux.die.net/man/3/readdir) under the hood
+on OS X and Linux, the order of files inside directories is [not guaranteed](http://stackoverflow.com/questions/8977441/does-readdir-guarantee-an-order).
+
+## Installation
+
+    npm install recursive-readdir
+
+## Usage
+
+```javascript
+var recursive = require("recursive-readdir");
+
+recursive("some/path", function (err, files) {
+  // `files` is an array of file paths
+  console.log(files);
+});
+```
+
+It can also take a list of files to ignore.
+
+```javascript
+var recursive = require("recursive-readdir");
+
+// ignore files named "foo.cs" or files that end in ".html".
+recursive("some/path", ["foo.cs", "*.html"], function (err, files) {
+  console.log(files);
+});
+```
+
+You can also pass functions which are called to determine whether or not to
+ignore a file:
+
+```javascript
+var recursive = require("recursive-readdir");
+
+function ignoreFunc(file, stats) {
+  // `file` is the path to the file, and `stats` is an `fs.Stats`
+  // object returned from `fs.lstat()`.
+  return stats.isDirectory() && path.basename(file) == "test";
+}
+
+// Ignore files named "foo.cs" and descendants of directories named test
+recursive("some/path", ["foo.cs", ignoreFunc], function (err, files) {
+  console.log(files);
+});
+```
+
+## Promises
+You can omit the callback and return a promise instead.
+
+```javascript
+var recursive = require("recursive-readdir");
+
+recursive("some/path").then(
+  function(files) {
+    console.log("files are", files);
+  },
+  function(error) {
+    console.error("something exploded", error);
+  }
+);
+```
+
+The ignore strings support Glob syntax via
+[minimatch](https://github.com/isaacs/minimatch).
