# URLx
[Golang](http://golang.org/) pkg for URL parsing and normalization.
1. [Parsing URL](#parsing-url) ([GoDoc](https://godoc.org/github.com/goware/urlx#Parse))
2. [Normalizing URL](#normalizing-url) ([GoDoc](https://godoc.org/github.com/goware/urlx#Normalize))
3. [Splitting host:port from URL](#splitting-hostport-from-url) ([GoDoc](https://godoc.org/github.com/goware/urlx#SplitHostPort))
4. [Resolving IP address from URL](#resolving-ip-address-from-url) ([GoDoc](https://godoc.org/github.com/goware/urlx#Resolve))

## Parsing URL
The [urlx.Parse()](https://godoc.org/github.com/goware/urlx#Parse) is compatible with the same function from [net/url](https://golang.org/pkg/net/url/#Parse) pkg, but has slightly different behavior. It enforces default scheme and favors absolute URLs over relative paths.
### Difference between [urlx](https://godoc.org/github.com/goware/urlx#Parse) and [net/url](https://golang.org/pkg/net/url/#Parse)
github.com/goware/urlx
net/url
urlx.Parse("example.com")
&url.URL{
Scheme: "http",
Host: "example.com",
Path: "",
}
url.Parse("example.com")
&url.URL{
Scheme: "",
Host: "",
Path: "example.com",
}
urlx.Parse("localhost:8080")
&url.URL{
Scheme: "http",
Host: "localhost:8080",
Path: "",
Opaque: "",
}
url.Parse("localhost:8080")
&url.URL{
Scheme: "localhost",
Host: "",
Path: "",
Opaque: "8080",
}
urlx.Parse("user.local:8000/path")
&url.URL{
Scheme: "http",
Host: "user.local:8000",
Path: "/path",
Opaque: "",
}
url.Parse("user.local:8000/path")
&url.URL{
Scheme: "user.local",
Host: "",
Path: "",
Opaque: "8000/path",
}
### Usage
```go
import "github.com/goware/urlx"
func main() {
url, _ := urlx.Parse("example.com")
// url.Scheme == "http"
// url.Host == "example.com"
fmt.Print(url)
// Prints http://example.com
}
```
## Normalizing URL
The [urlx.Normalize()](https://godoc.org/github.com/goware/urlx#Normalize) function normalizes the URL using the predefined subset of [Purell](https://github.com/PuerkitoBio/purell) flags.
### Usage
```go
import "github.com/goware/urlx"
func main() {
url, _ := urlx.Parse("localhost:80///x///y/z/../././index.html?b=y&a=x#t=20")
normalized, _ := urlx.Normalize(url)
fmt.Print(normalized)
// Prints http://localhost/x/y/index.html?a=x&b=y#t=20
}
```
## Splitting host:port from URL
The [urlx.SplitHostPort()](https://godoc.org/github.com/goware/urlx#SplitHostPort) is compatible with the same function from [net](https://golang.org/pkg/net/) pkg, but has slightly different behavior. It doesn't remove brackets from `[IPv6]` host.
### Usage
```go
import "github.com/goware/urlx"
func main() {
url, _ := urlx.Parse("localhost:80")
host, port, _ := urlx.SplitHostPort(url)
fmt.Print(host)
// Prints localhost
fmt.Print(port)
// Prints 80
}
```
## Resolving IP address from URL
The [urlx.Resolve()](https://godoc.org/github.com/goware/urlx#Resolve) is compatible with [ResolveIPAddr()](https://golang.org/pkg/net/#ResolveIPAddr) from [net](https://golang.org/pkg/net/).
### Usage
```go
url, _ := urlx.Parse("localhost")
ip, _ := urlx.Resolve(url)
fmt.Print(ip)
// Prints 127.0.0.1
```
