go-jupyter

go-jupyter is a Go package that provides a Jupyter Protocol client for communication with Jupyter kernels. It enables Go programs to interact with Jupyter kernels, execute code, and receive responses.

Installation

To install the package, use the following go get command:

go get -u github.com/crackcomm/go-jupyter

Usage

Here's a basic example of using the go-jupyter package to create a Jupyter kernel client and execute code:

package main

import (
	"context"
	"fmt"
	"log"

	"github.com/crackcomm/go-jupyter/jupyter"
)

func main() {
	// Load Jupyter kernel connection info from a configuration file
	info, err := jupyter.ReadConfigFile("path/to/connection_info.json")
	if err != nil {
		log.Fatal(err)
	}

	// Create a new Jupyter kernel client
	client, err := jupyter.NewClient(context.Background(), &info)
	if err != nil {
		log.Fatal(err)
	}
	defer client.Close()

	// Define the code to be executed
	code := "print('Hello, Jupyter!')"

	// Execute the code
	result, ch, err := client.Execute(&jupyter.ExecutionRequest{
		Code: code,
	})
	if err != nil {
		log.Fatal(err)
	}

	for msg := range ch {
		fmt.Printf("Kernel output: %#v", msg)
	}

	// Print the execution result
	fmt.Printf("Execution Status: %s\n", result.Status)
	fmt.Printf("Execution Count: %d\n", result.ExecutionCount)
}

This example demonstrates loading connection information from a file, creating a client, and executing a simple code snippet. The go-jupyter package provides additional functionality for inspecting code, handling input/output channels, and more.
