+# Ordered Map for golang
+
+[![Build Status](https://travis-ci.org/cevaris/ordered_map.svg?branch=master)](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}, ]
+```
+

+This program reads a file containing function prototypes
+(like syscall_aix.go) and generates system call bodies.
+The prototypes are marked by lines beginning with "//sys"
+and read like func declarations if //sys is replaced by func, but:
+	* The parameter lists must give a name for each argument.
+	  This includes return parameters.
+	* The parameter lists must give a type for each argument:
+	  the (x, y, z int) shorthand is not allowed.
+	* If the return parameter is an error number, it must be named err.
+	* If go func name needs to be different than its libc name,
+	* or the function is not in libc, name could be specified
+	* at the end, after "=" sign, like
+	  //sys getsockopt(s int, level int, name int, val uintptr, vallen *_Socklen) (err error) = libsocket.getsockopt
+
+
+This program will generate three files and handle both gc and gccgo implementation:
+  - zsyscall_aix_ppc64.go: the common part of each implementation (error handler, pointer creation)
+  - zsyscall_aix_ppc64_gc.go: gc part with //go_cgo_import_dynamic and a call to syscall6
+  - zsyscall_aix_ppc64_gccgo.go: gccgo part with C function and conversion to C type.
+
+ The generated code looks like this
+
+zsyscall_aix_ppc64.go
+func asyscall(...) (n int, err error) {
+	 // Pointer Creation
+	 r1, e1 := callasyscall(...)
+	 // Type Conversion
+	 // Error Handler

+ This program reads a file containing function prototypes

+ The prototypes are marked by lines beginning with "//sys"
+ and read like func declarations if //sys is replaced by func, but:
+	* The parameter lists must give a name for each argument.
+	  This includes return parameters.
+	* The parameter lists must give a type for each argument:
+	  the (x, y, z int) shorthand is not allowed.
+	* If the return parameter is an error number, it must be named err.
+	* If go func name needs to be different than its libc name,
+	* or the function is not in libc, name could be specified
+	* at the end, after "=" sign, like
+	  //sys getsockopt(s int, level int, name int, val uintptr, vallen *_Socklen) (err error) = libsocket.getsockopt
