# filetype [](https://travis-ci.org/h2non/filetype) [](https://godoc.org/github.com/h2non/filetype) [](http://goreportcard.com/report/h2non/filetype) [](https://github.com/h2non/gentleman)
|
||||
|
||||
Small and dependency free [Go](https://golang.org) package to infer file and MIME type checking the [magic numbers](https://en.wikipedia.org/wiki/Magic_number_(programming)#Magic_numbers_in_files) signature.
|
||||
|
||||
For SVG file type checking, see [go-is-svg](https://github.com/h2non/go-is-svg) package.
|
||||
|
||||
## Features
|
||||
|
||||
- Supports a [wide range](#supported-types) of file types
|
||||
- Provides file extension and proper MIME type
|
||||
- File discovery by extension or MIME type
|
||||
- File discovery by class (image, video, audio...)
|
||||
- Provides a bunch of helpers and file matching shortcuts
|
||||
- [Pluggable](#add-additional-file-type-matchers): add custom new types and matchers
|
||||
- Simple and semantic API
|
||||
- [Blazing fast](#benchmarks), even processing large files
|
||||
- Only first 261 bytes representing the max file header is required, so you can just [pass a slice](#file-header)
|
||||
- Dependency free (just Go code, no C compilation needed)
|
||||
- Cross-platform file recognition
|
||||
|
||||
## Installation
|
||||
|
||||
```bash
|
||||
go get gopkg.in/h2non/filetype.v1
|
||||
```
|
||||
|
||||
## API
|
||||
|
||||
See [Godoc](https://godoc.org/github.com/h2non/filetype) reference.
|
||||
|
||||
### Subpackages
|
||||
|
||||
- [`gopkg.in/h2non/filetype.v1/types`](https://godoc.org/github.com/h2non/filetype/types)
|

- [`gopkg.in/h2non/filetype.v1/matchers`](https://godoc.org/github.com/h2non/filetype/matchers)
|
||||
|
||||
## Examples
|
||||
|
||||
#### Simple file type checking
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"fmt"
|
||||
"gopkg.in/h2non/filetype.v1"
|
||||
"io/ioutil"
|
||||
)
|
||||
|
||||
func main() {
|
||||
buf, _ := ioutil.ReadFile("sample.jpg")
|
||||
|
||||
kind, unknown := filetype.Match(buf)
|
||||
if unknown != nil {
|
||||
fmt.Printf("Unknown: %s", unknown)
|
||||
return
|
||||
}
|
||||
|
||||
fmt.Printf("File type: %s. MIME: %s\n", kind.Extension, kind.MIME.Value)
|
||||
}
|
||||
```
|
||||
|
||||
#### Check type class
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"fmt"
|
||||
"gopkg.in/h2non/filetype.v1"
|
||||
"io/ioutil"
|
||||
)
|
||||
|
||||
func main() {
|
||||
buf, _ := ioutil.ReadFile("sample.jpg")
|
||||
|
||||
if filetype.IsImage(buf) {
|
||||
fmt.Println("File is an image")
|
||||
} else {
|
||||
fmt.Println("Not an image")
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### Supported type
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"fmt"
|
||||
"gopkg.in/h2non/filetype.v1"
|
||||
)
|
||||
|
||||
func main() {
|
||||
// Check if file is supported by extension
|
||||
if filetype.IsSupported("jpg") {
|
||||
fmt.Println("Extension supported")
|
||||
} else {
|
||||
fmt.Println("Extension not supported")
|
||||
}
|
||||
|
||||
// Check if file is supported by extension
|
||||
if filetype.IsMIMESupported("image/jpeg") {
|
||||
fmt.Println("MIME type supported")
|
||||
} else {
|
||||
fmt.Println("MIME type not supported")
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### File header
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"fmt"
|
||||
"gopkg.in/h2non/filetype.v1"
|
||||
"io/ioutil"
|
||||
)
|
||||
|
||||
func main() {
|
||||
// Open a file descriptor
|
||||
file, _ := os.Open("movie.mp4")
|
||||
|
||||
// We only have to pass the file header = first 261 bytes
|
||||
head := make([]byte, 261)
|
||||
file.Read(head)
|
||||
|
||||
if filetype.IsImage(head) {
|
||||
fmt.Println("File is an image")
|
||||
} else {
|
||||
fmt.Println("Not an image")
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
#### Add additional file type matchers
|
||||
|
||||
```go
|
||||
package main
|
||||
|
||||
import (
|
||||
"fmt"
|
||||
"gopkg.in/h2non/filetype.v1"
|
||||
)
|
||||
|
||||
var fooType = filetype.NewType("foo", "foo/foo")
|
||||
|
||||
func fooMatcher(buf []byte) bool {
|
||||
return len(buf) > 1 && buf[0] == 0x01 && buf[1] == 0x02
|
||||
}
|
||||
|
||||
func main() {
|
||||
// Register the new matcher and its type
|
||||
filetype.AddMatcher(fooType, fooMatcher)
|
||||
|
||||
// Check if the new type is supported by extension
|
||||
if filetype.IsSupported("foo") {
|
||||
fmt.Println("New supported type: foo")
|
||||
}
|
||||
|
||||
// Check if the new type is supported by MIME
|
||||
if filetype.IsMIMESupported("foo/foo") {
|
||||
fmt.Println("New supported MIME type: foo/foo")
|
||||
}
|
||||
|
||||
// Try to match the file
|
||||
fooFile := []byte{0x01, 0x02}
|
||||
kind, _ := filetype.Match(fooFile)
|
||||
if kind == filetype.Unknown {
|
||||
fmt.Println("Unknown file type")
|
