+# YAML support for the Go language
+
+Fork
+----
+This fork is an improved version of the go-yaml/yaml package, enhanced to inject `__origin__` metadata into YAML mapping nodes during decoding, recording the file, line, and column of each key.
+
+To enable origin tracking, call `Origin` on the decoder before decoding:
+
+```go
+dec := yaml.NewDecoder(r)
+dec.Origin(true, "myfile.yaml")
+
+var v interface{}
+dec.Decode(&v)
+// Each decoded map now contains a synthetic "__origin__" key whose value is
+// a compact []interface{} sequence:
+//   [file, key_name, key_line, key_col, nf, f1_name, f1_delta, f1_col, ..., ns, s1_name, s1_count, (name, delta, col)×count, ...]
+// where nf = number of scalar/sequence fields, ns = number of sequences with item locations,
+// and deltas are line offsets from key_line.
+```
+
+Origin nodes are synthetic: their key node has `Line == 0` (since real YAML lines are 1-based), which allows callers to detect and strip them. The [oasdiff/yaml](https://github.com/oasdiff/yaml) package uses this to build an `OriginTree` before JSON conversion, keeping `__origin__` entirely out of the decoded struct.
+
+Introduction
+------------
+
+The yaml package enables Go programs to comfortably encode and decode YAML
+values. It was developed within [Canonical](https://www.canonical.com) as
+part of the [juju](https://juju.ubuntu.com) project, and is based on a
+pure Go port of the well-known [libyaml](http://pyyaml.org/wiki/LibYAML)
+C library to parse and generate YAML data quickly and reliably.
+
+Compatibility
+-------------
+
+The yaml package supports most of YAML 1.2, but preserves some behavior
+from 1.1 for backwards compatibility.
+
+Specifically, as of v3 of the yaml package:
+
+ - YAML 1.1 bools (_yes/no, on/off_) are supported as long as they are being
+   decoded into a typed bool value. Otherwise they behave as a string. Booleans
+   in YAML 1.2 are _true/false_ only.
+ - Octals encode and decode as _0777_ per YAML 1.1, rather than _0o777_
+   as specified in YAML 1.2, because most parsers still use the old format.
+   Octals in the  _0o777_ format are supported though, so new files work.
+ - Does not support base-60 floats. These are gone from YAML 1.2, and were
+   actually never supported by this package as it's clearly a poor choice.

+Example
+-------
+
+```Go
+package main
+
+import (
+        "fmt"
+        "log"
+
+        "github.com/oasdiff/yaml3"
+)
+
+var data = `
+a: Easy!
+b:
+  c: 2
+  d: [3, 4]
+`
+
+// Note: struct fields must be public in order for unmarshal to
+// correctly populate the data.
+type T struct {
+        A string
+        B struct {
+                RenamedC int   `yaml:"c"`
+                D        []int `yaml:",flow"`
+        }
+}
+
+func main() {
+        t := T{}
+    
+        err := yaml.Unmarshal([]byte(data), &t)
+        if err != nil {
+                log.Fatalf("error: %v", err)
+        }
+        fmt.Printf("--- t:\n%v\n\n", t)
+    
+        d, err := yaml.Marshal(&t)
+        if err != nil {
+                log.Fatalf("error: %v", err)
+        }
+        fmt.Printf("--- t dump:\n%s\n\n", string(d))
+    
+        m := make(map[interface{}]interface{})
+    
+        err = yaml.Unmarshal([]byte(data), &m)
+        if err != nil {
+                log.Fatalf("error: %v", err)
+        }
+        fmt.Printf("--- m:\n%v\n\n", m)
+    
+        d, err = yaml.Marshal(&m)
+        if err != nil {
+                log.Fatalf("error: %v", err)
+        }
+        fmt.Printf("--- m dump:\n%s\n\n", string(d))
+}
+```
+
+This example will generate the following output:
+
+```
+--- t:
+{Easy! {2 [3 4]}}
+
+--- t dump:
+a: Easy!
+b:
+  c: 2
+  d: [3, 4]
+
+
+--- m:
+map[a:Easy! b:map[c:2 d:[3 4]]]
+
+--- m dump:
+a: Easy!
+b:
+  c: 2
+  d:
+  - 3
+  - 4
+```
