Anko is a scriptable interpreter written in Go.
![](https://raw.githubusercontent.com/mattn/anko/master/anko.png)
(Picture licensed under CC BY-SA 3.0, photo by Ocdp)
## Usage Example - Embedded
```go
package main
import (
"fmt"
"log"
"github.com/surdeus/goblin/src/tool/anko/env"
"github.com/surdeus/goblin/src/tool/anko/vm"
)
func main() {
e := env.NewEnv()
err := e.Define("println", fmt.Println)
if err != nil {
log.Fatalf("Define error: %v\n", err)
}
script := `
println("Hello World :)")
`
_, err = vm.Execute(e, nil, script)
if err != nil {
log.Fatalf("Execute error: %v\n", err)
}
// output: Hello World :)
}
```
More examples are located in the GoDoc:
https://godoc.org/github.com/surdeus/goblin/src/tool/anko/vm
## Usage Example - Command Line
### Building
```
go get github.com/surdeus/goblin/src/tool/anko
go install github.com/surdeus/goblin/src/tool/anko
```
### Running an Anko script file named script.ank
```
./anko script.ank
```
## Anko Script Quick Start
```
// declare variables
x = 1
y = x + 1
// print using outside the script defined println function
println(x + y) // 3
// if else statement
if x < 1 || y < 1 {
println(x)
} else if x < 1 && y < 1 {
println(y)
} else {
println(x + y)
}
// slice
a = []interface{1, 2, 3}
println(a) // [1 2 3]
println(a[0]) // 1
// map
a = map[interface]interface{"x": 1}
println(a) // map[x:1]
a.b = 2
a["c"] = 3
println(a["b"]) // 2
println(a.c) // 3
// struct
a = make(struct {
A int64,
B float64
})
a.A = 4
a.B = 5.5
println(a.A) // 4
println(a.B) // 5.5
// function
func a (x) {
println(x + 1)
}
a(5) // 6
```
