go-querystring is a Go library for encoding structs into URL query parameters.

## Usage ##

```go
import "github.com/google/go-querystring/query"
```

go-querystring is designed to assist in scenarios where you want to construct a
URL using a struct that represents the URL query parameters.  You might do this
to enforce the type safety of your parameters, for example, as is done in the
[go-github][] library.

The query package exports a single `Values()` function.  A simple example:

```go
type Options struct {
  Query   string `url:"q"`
  ShowAll bool   `url:"all"`
  Page    int    `url:"page"`
}

opt := Options{ "foo", true, 2 }
v, _ := query.Values(opt)
fmt.Print(v.Encode()) // will output: "q=foo&all=true&page=2"
```

See the [package godocs][] for complete documentation on supported types and
formatting options.
