+# jsonpath
+
+This package extends the [json.Decoder](https://golang.org/pkg/encoding/json/#Decoder) to support navigating a stream of JSON tokens. You should be able to use this extended Decoder places where a json.Decoder would have been used.
+
+This Decoder has the following enhancements...
+ * The [Scan](https://godoc.org/github.com/exponent-io/jsonpath/#Decoder.Scan) method supports scanning a JSON stream while extracting particular values along the way using [PathActions](https://godoc.org/github.com/exponent-io/jsonpath#PathActions).
+ * The [SeekTo](https://godoc.org/github.com/exponent-io/jsonpath#Decoder.SeekTo) method supports seeking forward in a JSON token stream to a particular path.
+ * The [Path](https://godoc.org/github.com/exponent-io/jsonpath#Decoder.Path) method returns the path of the most recently parsed token.
+ * The [Token](https://godoc.org/github.com/exponent-io/jsonpath#Decoder.Token) method has been modified to distinguish between strings that are object keys and strings that are values. Object key strings are returned as the [KeyString](https://godoc.org/github.com/exponent-io/jsonpath#KeyString) type rather than a native string.
+
+## Installation
+
+    go get -u github.com/exponent-io/jsonpath
+
+## Example Usage
+
+#### SeekTo
+
+```go
+import "github.com/exponent-io/jsonpath"
+
+var j = []byte(`[
+  {"Space": "YCbCr", "Point": {"Y": 255, "Cb": 0, "Cr": -10}},
+  {"Space": "RGB",   "Point": {"R": 98, "G": 218, "B": 255}}
+]`)
+
+w := json.NewDecoder(bytes.NewReader(j))
+var v interface{}
+
+w.SeekTo(1, "Point", "G")
+w.Decode(&v) // v is 218
+```
+
+#### Scan with PathActions
+
+```go
+var j = []byte(`{"colors":[
+  {"Space": "YCbCr", "Point": {"Y": 255, "Cb": 0, "Cr": -10, "A": 58}},
+  {"Space": "RGB",   "Point": {"R": 98, "G": 218, "B": 255, "A": 231}}
+]}`)
+
+var actions PathActions
+
+// Extract the value at Point.A
+actions.Add(func(d *Decoder) error {
+  var alpha int
+  err := d.Decode(&alpha)
+  fmt.Printf("Alpha: %v\n", alpha)
+  return err
+}, "Point", "A")
+
+w := NewDecoder(bytes.NewReader(j))
+w.SeekTo("colors", 0)
+
+var ok = true
+var err error
+for ok {
+  ok, err = w.Scan(&actions)
+  if err != nil && err != io.EOF {
+    panic(err)
+  }
+}
+```
