# File system notifications for Go
[![GoDoc](https://godoc.org/github.com/howeyc/fsnotify?status.png)](http://godoc.org/github.com/howeyc/fsnotify)
Cross platform: Windows, Linux, BSD and OS X.
## Moving Notice
There is a fork being actively developed with a new API in preparation for the Go Standard Library:
[github.com/go-fsnotify/fsnotify](https://github.com/go-fsnotify/fsnotify)
## Example:
```go
package main
import (
"log"
"github.com/howeyc/fsnotify"
)
func main() {
watcher, err := fsnotify.NewWatcher()
if err != nil {
log.Fatal(err)
}
done := make(chan bool)
// Process events
go func() {
for {
select {
case ev := <-watcher.Event:
log.Println("event:", ev)
case err := <-watcher.Error:
log.Println("error:", err)
}
}
}()
err = watcher.Watch("testDir")
if err != nil {
log.Fatal(err)
}
// Hang so program doesn't exit
<-done
/* ... do stuff ... */
watcher.Close()
}
```
For each event:
* Name
* IsCreate()
* IsDelete()
* IsModify()
* IsRename()
## FAQ
**When a file is moved to another directory is it still being watched?**
No (it shouldn't be, unless you are watching where it was moved to).
**When I watch a directory, are all subdirectories watched as well?**
No, you must add watches for any directory you want to watch (a recursive watcher is in the works [#56][]).
**Do I have to watch the Error and Event channels in a separate goroutine?**
As of now, yes. Looking into making this single-thread friendly (see [#7][])
**Why am I receiving multiple events for the same file on OS X?**
Spotlight indexing on OS X can result in multiple events (see [#62][]). A temporary workaround is to add your folder(s) to the *Spotlight Privacy settings* until we have a native FSEvents implementation (see [#54][]).
**How many files can be watched at once?**
There are OS-specific limits as to how many watches can be created:
* Linux: /proc/sys/fs/inotify/max_user_watches contains the limit,
reaching this limit results in a "no space left on device" error.
* BSD / OSX: sysctl variables "kern.maxfiles" and "kern.maxfilesperproc", reaching these limits results in a "too many open files" error.

Goroutine local storage
### IMPORTANT NOTE ###
It is my duty to point you to https://blog.golang.org/context, which is how
Google solves all of the problems you'd perhaps consider using this package
for at scale.
One downside to Google's approach is that *all* of your functions must have
a new first argument, but after clearing that hurdle everything else is much
better.
If you aren't interested in this warning, read on.
### Huhwaht? Why? ###
Every so often, a thread shows up on the
[golang-nuts](https://groups.google.com/d/forum/golang-nuts) asking for some
form of goroutine-local-storage, or some kind of goroutine id, or some kind of
context. There are a few valid use cases for goroutine-local-storage, one of
the most prominent being log line context. One poster was interested in being
able to log an HTTP request context id in every log line in the same goroutine
as the incoming HTTP request, without having to change every library and
function call he was interested in logging.
This would be pretty useful. Provided that you could get some kind of
goroutine-local-storage, you could call
[log.SetOutput](http://golang.org/pkg/log/#SetOutput) with your own logging
writer that checks goroutine-local-storage for some context information and
adds that context to your log lines.
But alas, Andrew Gerrand's typically diplomatic answer to the question of
goroutine-local variables was:
> We wouldn't even be having this discussion if thread local storage wasn't
> useful. But every feature comes at a cost, and in my opinion the cost of
> threadlocals far outweighs their benefits. They're just not a good fit for
> Go.
So, yeah, that makes sense. That's a pretty good reason for why the language
won't support a specific and (relatively) unuseful feature that requires some
runtime changes, just for the sake of a little bit of log improvement.
But does Go require runtime changes?
### How it works ###
Go has pretty fantastic introspective and reflective features, but one thing Go
doesn't give you is any kind of access to the stack pointer, or frame pointer,
or goroutine id, or anything contextual about your current stack. It gives you
access to your list of callers, but only along with program counters, which are
fixed at compile time.
But it does give you the stack.
So, we define 16 special functions and embed base-16 tags into the stack using
the call order of those 16 functions. Then, we can read our tags back out of
the stack looking at the callers list.
We then use these tags as an index into a traditional map for implementing
this library.
### What are people saying? ###
"Wow, that's horrifying."
"This is the most terrible thing I have seen in a very long time."
"Where is it getting a context from? Is this serializing all the requests?
What the heck is the client being bound to? What are these tags? Why does he
need callers? Oh god no. No no no."
### Docs ###
Please see the docs at http://godoc.org/github.com/jtolds/gls
### Related ###
If you're okay relying on the string format of the current runtime stacktrace
including a unique goroutine id (not guaranteed by the spec or anything, but
very unlikely to change within a Go release), you might be able to squeeze
out a bit more performance by using this similar library, inspired by some
code Brad Fitzpatrick wrote for debugging his HTTP/2 library:
https://github.com/tylerb/gls (in contrast, jtolds/gls doesn't require
any knowledge of the string format of the runtime stacktrace, which
probably adds unnecessary overhead).

referenced in goconvey's `convey` package
(github.com/smartystreets/goconvey/convey) for use with the So(...) method. They
can also be used in traditional Go test functions and even in applicaitons.
## Usage
#### func GoConveyMode
```go
func GoConveyMode(yes bool)
```
GoConveyMode provides control over JSON serialization of failures. When using
the assertions in this package from the convey package JSON results are very
helpful and can be rendered in a DIFF view. In that case, this function will be
called with a true value to enable the JSON serialization. By default, the
assertions in this package will not serializer a JSON result, making standalone
ussage more convenient.
#### func ShouldAlmostEqual
```go

running assertions on arbitrary arguments in any context, be it for testing or
even application logging. It allows you to perform assertion-like behavior (and
get nicely formatted messages detailing discrepancies) but without the program
blowing up or panicking. All that is required is to import this package and call
`So` with one of the assertions exported by this package as the second
parameter. The first return parameter is a boolean indicating if the assertion
was true. The second return parameter is the well-formatted message showing why
an assertion was incorrect, or blank if the assertion was correct.
Example:
if ok, message := So(x, ShouldBeGreaterThan, y); !ok {
log.Println(message)
}
#### type Assertion

Example: assertions.New(t).So(1, should.Equal, 1)
#### func (*Assertion) Failed
```go
func (this *Assertion) Failed() bool
```
Failed reports whether any calls to So (on this Assertion instance) have failed.
#### func (*Assertion) So
```go
func (this *Assertion) So(actual interface{}, assert assertion, expected ...interface{}) bool
```
So calls the standalone So function and additionally, calls t.Error in failure
scenarios.
#### type Serializer
```go
type Serializer interface {
// contains filtered or unexported methods
}
```

[![GoDoc](https://godoc.org/github.com/smartystreets/assertions/internal/oglematchers?status.svg)](https://godoc.org/github.com/smartystreets/assertions/internal/oglematchers)
`oglematchers` is a package for the Go programming language containing a set of
matchers, useful in a testing or mocking framework, inspired by and mostly
compatible with [Google Test][googletest] for C++ and
[Google JS Test][google-js-test]. The package is used by the
[ogletest][ogletest] testing framework and [oglemock][oglemock] mocking
framework, which may be more directly useful to you, but can be generically used
elsewhere as well.
A "matcher" is simply an object with a `Matches` method defining a set of golang
values matched by the matcher, and a `Description` method describing that set.
For example, here are some matchers:
```go
// Numbers
Equals(17.13)
LessThan(19)
// Strings
Equals("taco")
HasSubstr("burrito")
MatchesRegex("t.*o")
// Combining matchers
AnyOf(LessThan(17), GreaterThan(19))
```
There are lots more; see [here][reference] for a reference. You can also add
your own simply by implementing the `oglematchers.Matcher` interface.
Installation
------------
First, make sure you have installed Go 1.0.2 or newer. See
[here][golang-install] for instructions.
Use the following command to install `oglematchers` and keep it up to date:
go get -u github.com/smartystreets/assertions/internal/oglematchers
Documentation
-------------
See [here][reference] for documentation. Alternatively, you can install the
package and then use `godoc`:
godoc github.com/smartystreets/assertions/internal/oglematchers

// built-in comparison operator is legal (except for structs, which this
// matcher does not support), but for convenience the following rules also

//
// * Type checking is done based on underlying types rather than actual
// types, so that e.g. two aliases for string can be compared:
//
// type stringAlias1 string
// type stringAlias2 string
//
// a := "taco"
// b := stringAlias1("taco")

//
// ExpectTrue(a == b) // Legal, passes
// ExpectTrue(b == c) // Illegal, doesn't compile
//
// ExpectThat(a, Equals(b)) // Passes
// ExpectThat(b, Equals(c)) // Passes
//
// * Values of numeric type are treated as if they were abstract numbers, and
// compared accordingly. Therefore Equals(17) will match int(17),
// int16(17), uint(17), float32(17), complex64(17), and so on.
//
// If you want a stricter matcher that contains no such cleverness, see

// Package oglematchers provides a set of matchers useful in a testing or
// mocking framework. These matchers are inspired by and mostly compatible with
// Google Test for C++ and Google JS Test.
//
// This package is used by github.com/smartystreets/assertions/internal/ogletest and
// github.com/smartystreets/assertions/internal/oglemock, which may be more directly useful if you're not
// writing your own testing package or defining your own matchers.
package oglematchers
// A Matcher is some predicate implicitly defining a set of values that it
// matches. For example, GreaterThan(17) matches all numeric values greater
// than 17, and HasSubstr("taco") matches all strings with the substring
// "taco".
//
// Matchers are typically exposed to tests via constructor functions like
// HasSubstr. In order to implement such a function you can either define your
// own matcher type or use NewMatcher.
type Matcher interface {
// Check whether the supplied value belongs to the the set defined by the
// matcher. Return a non-nil error if and only if it does not.
//
// The error describes why the value doesn't match. The error text is a
// relative clause that is suitable for being placed after the value. For
// example, a predicate that matches strings with a particular substring may,
// when presented with a numerical value, return the following error text:
//
// "which is not a string"
//
// Then the failure message may look like:
//
// Expected: has substring "taco"
// Actual: 17, which is not a string
//
// If the error is self-apparent based on the description of the matcher, the
// error text may be empty (but the error still non-nil). For example:
//
// Expected: 17
// Actual: 19
//
// If you are implementing a new matcher, see also the documentation on
// FatalError.
Matches(candidate interface{}) error
// Description returns a string describing the property that values matching
// this matcher have, as a verb phrase where the subject is the value. For
// example, "is greather than 17" or "has substring "taco"".
Description() string
}
// FatalError is an implementation of the error interface that may be returned
// from matchers, indicating the error should be propagated. Returning a
// *FatalError indicates that the matcher doesn't process values of the
// supplied type, or otherwise doesn't know how to handle the value.
//
// For example, if GreaterThan(17) returned false for the value "taco" without
// a fatal error, then Not(GreaterThan(17)) would return true. This is
// technically correct, but is surprising and may mask failures where the wrong
// sort of matcher is accidentally used. Instead, GreaterThan(17) can return a
// fatal error, which will be propagated by Not().
type FatalError struct {
errorText string
}
// NewFatalError creates a FatalError struct with the supplied error text.
func NewFatalError(s string) *FatalError {
