+# Ordered Map for golang
+
+[](https://travis-ci.org/cevaris/ordered_map)
+
+**OrderedMap** is a Python port of OrderedDict implemented in golang. Golang's builtin `map` purposefully randomizes the iteration of stored key/values. **OrderedMap** struct preserves inserted key/value pairs; such that on iteration, key/value pairs are received in inserted (first in, first out) order.
+
+
+## Features
+- Full support Key/Value for all data types
+- Exposes an Iterator that iterates in order of insertion
+- Full Get/Set/Delete map interface
+- Supports Golang v1.3 through v1.12
+
+## Download and Install
+
+`go get https://github.com/cevaris/ordered_map.git`
+
+
+## Examples
+
+### Create, Get, Set, Delete
+
+```go
+package main
+
+import (
+ "fmt"
+ "github.com/cevaris/ordered_map"
+)
+
+func main() {
+
+ // Init new OrderedMap
+ om := ordered_map.NewOrderedMap()
+
+ // Set key
+ om.Set("a", 1)
+ om.Set("b", 2)
+ om.Set("c", 3)
+ om.Set("d", 4)
+
+ // Same interface as builtin map
+ if val, ok := om.Get("b"); ok == true {
+ // Found key "b"
+ fmt.Println(val)
+ }
+
+ // Delete a key
+ om.Delete("c")
+
+ // Failed Get lookup becase we deleted "c"
+ if _, ok := om.Get("c"); ok == false {
+ // Did not find key "c"
+ fmt.Println("c not found")
+ }
+
+ fmt.Println(om)
+}
+```
+
+
+### Iterator
+
+```go
+n := 100
+om := ordered_map.NewOrderedMap()
+
+for i := 0; i < n; i++ {
+ // Insert data into OrderedMap
+ om.Set(i, fmt.Sprintf("%d", i * i))
+}
+
+// Iterate though values
+// - Values iteration are in insert order
+// - Returned in a key/value pair struct
+iter := om.IterFunc()
+for kv, ok := iter(); ok; kv, ok = iter() {
+ fmt.Println(kv, kv.Key, kv.Value)
+}
+```
+
+### Custom Structs
+
+```go
+om := ordered_map.NewOrderedMap()
+om.Set("one", &MyStruct{1, 1.1})
+om.Set("two", &MyStruct{2, 2.2})
+om.Set("three", &MyStruct{3, 3.3})
+
+fmt.Println(om)
+// Ouput: OrderedMap[one:&{1 1.1}, two:&{2 2.2}, three:&{3 3.3}, ]
+```
+
+## For Development
+
+Git clone project
+
+`git clone https://github.com/cevaris/ordered_map.git`
+
+Build and install project
+
+`make`
+
+Run tests
+
+`make test`
