+
+[![Build Status](https://travis-ci.org/radovskyb/watcher.svg?branch=master)](https://travis-ci.org/radovskyb/watcher)
+
+`watcher` is a Go package for watching for files or directory changes (recursively or non recursively) without using filesystem events, which allows it to work cross platform consistently.
+
+`watcher` watches for changes and notifies over channels either anytime an event or an error has occurred.
+
+Events contain the `os.FileInfo` of the file or directory that the event is based on and the type of event and file or directory path.

+
+# Update
+Event.Path for Rename and Move events is now returned in the format of `fromPath -> toPath`
+
+#### Chmod event is not supported under windows.
+
+# Installation
+
+```shell
+go get -u github.com/radovskyb/watcher/...
+```
+
+# Features
+
+- Customizable polling interval.
+- Filter Events.
+- Watch folders recursively or non-recursively.
+- Choose to ignore hidden files.
+- Choose to ignore specified files and folders.
+- Notifies the `os.FileInfo` of the file that the event is based on. e.g `Name`, `ModTime`, `IsDir`, etc.
+- Notifies the full path of the file that the event is based on or the old and new paths if the event was a `Rename` or `Move` event.
+- Limit amount of events that can be received per watching cycle.
+- List the files being watched.
+- Trigger custom events.
+
+# Todo
+
+- Write more tests.
+- Write benchmarks.
+
+# Example
+
+```go
+package main
+
+import (
+	"fmt"
+	"log"
+	"time"
+
+	"github.com/radovskyb/watcher"
+)
+
+func main() {
+	w := watcher.New()
+
+	// SetMaxEvents to 1 to allow at most 1 event's to be received
+	// on the Event channel per watching cycle.
+	//
+	// If SetMaxEvents is not set, the default is to send all events.
+	w.SetMaxEvents(1)
+
+	// Only notify rename and move events.
+	w.FilterOps(watcher.Rename, watcher.Move)
+
+	go func() {
+		for {
+			select {
+			case event := <-w.Event:	
+				fmt.Println(event) // Print the event's info.
+			case err := <-w.Error:
+				log.Fatalln(err)
+			case <-w.Closed:
+				return
+			}
+		}
+	}()
+
+	// Watch this folder for changes.
+	if err := w.Add("."); err != nil {
+		log.Fatalln(err)
+	}
+
+	// Watch test_folder recursively for changes.
+	if err := w.AddRecursive("../test_folder"); err != nil {
+		log.Fatalln(err)
+	}
+
+	// Print a list of all of the files and folders currently
+	// being watched and their paths.
+	for path, f := range w.WatchedFiles() {
+		fmt.Printf("%s: %s\n", path, f.Name())
+	}
+
+	fmt.Println()
+
+	// Trigger 2 events after watcher started.
+	go func() {
+		w.Wait()
+		w.TriggerEvent(watcher.Create, nil)
+		w.TriggerEvent(watcher.Remove, nil)
+	}()
+
+	// Start the watching process - it'll check for changes every 100ms.
+	if err := w.Start(time.Millisecond * 100); err != nil {
+		log.Fatalln(err)
+	}
+}

+
+# Command
+
+`watcher` comes with a simple command which is installed when using the `go get` command from above.
+
+# Usage
+
+```
+Usage of watcher:
+  -cmd string
+    	command to run when an event occurs
+  -dotfiles
+    	watch dot files (default true)
+  -interval string
+    	watcher poll interval (default "100ms")
+  -keepalive
+    	keep alive when a cmd returns code != 0
+  -list
+    	list watched files on start
+  -pipe
+    	pipe event's info to command's stdin
+  -recursive
+    	watch folders recursively (default true)
+  -startcmd
+    	run the command when watcher starts
+```
+
+All of the flags are optional and watcher can also be called by itself:
+```shell
+watcher
+```
+(watches the current directory recursively for changes and notifies any events that occur.)
+
+A more elaborate example using the `watcher` command:
+```shell
+watcher -dotfiles=false -recursive=false -cmd="./myscript" main.go ../
+```
+In this example, `watcher` will ignore dot files and folders and won't watch any of the specified folders recursively. It will also run the script `./myscript` anytime an event occurs while watching `main.go` or any files or folders in the previous directory (`../`).
+
+Using the `pipe` and `cmd` flags together will send the event's info to the command's stdin when changes are detected.
+
+First create a file called `script.py` with the following contents:
+```python
+import sys
+
+for line in sys.stdin:
+	print (line + " - python")
+```
+
+Next, start watcher with the `pipe` and `cmd` flags enabled:
+```shell
+watcher -cmd="python script.py" -pipe=true
+```
+
+Now when changes are detected, the event's info will be output from the running python script.
