Installation

One command, zero external dependencies. Risor is a pure Go module.

Requirements

• Go 1.25 or later

Install the Module

go get github.com/deepnoodle-ai/risor/v2

Verify the Installation

Confirm everything works with a quick sanity check:

package main
 
import (
    "context"
    "fmt"
    "github.com/deepnoodle-ai/risor/v2"
)
 
func main() {
    result, err := risor.Eval(context.Background(), `1 + 1`)
    if err != nil {
        panic(err)
    }
    fmt.Println(result) // 2
}

Run it:

go run main.go

If you see 2, you're good to go.
