In the beginning, there was the Terminal, and it was good. But lo, we sought to make it even better by using Go to create a note pad application. For this grand quest, you'll need:

• A dash of Go knowledge (fear not, brave soul, for beginners are welcome!)
• The Go language installed in your trusty steed (your computer)
• A heart full of courage (and maybe some coffee)

Open your Terminal or Command Prompt and chant the following incantation:

mkdir go-note-pad && cd go-note-pad
go mod init go-note-pad

Behold! Your module, go-note-pad, is born.

Create a file named main.go. This is where the magic happens.

touch main.go

Within main.go, declare a structure that shall hold your musings:

package main

import "time"

// Note - A mystical container for your thoughts
type Note struct {
    ID        int
    Title     string
    Content   string
    CreatedAt time.Time
    UpdatedAt time.Time
}

Our application shall heed four sacred commands: Create, List, View, and Delete. Like the four winds, they breathe life into our application.

// In a real app, this function would save to a database
// But in our magical realm, we're printing to the console
func createNote(title, content string) {
    fmt.Printf("A new note titled '%s' has been created with content:\n%s\n", title, content)
}

// This potent spell lists all your notes
// Imagine it reading from a database of limitless knowledge
func listNotes() {
    fmt.Println("Behold! Your notes stretch out before you, endless as the stars...")
}

// Here, you'd fetch a single note by its ID and reveal its secrets
func viewNote(id int) {
    fmt.Printf("The contents of note %d are profound and full of mystery...\n", id)
}

// With a heavy heart, you may occasionally need to banish a note into the void
func deleteNote(id int) {
    fmt.Printf("Note %d has been consigned to oblivion...\n", id)
}

Fear not, for now, we venture into the dungeon of dbdiagrams.io to etch our database schema into the stone of eternity.

Behold our schema, a simple table of notes:

Table notes {
  id int [pk, increment]
  title varchar
  content text
  created_at datetime
  updated_at datetime
}

Armed with our schema, we'd typically use a spell like database/sql to connect to our database. However, since integrating a real database might anger the demo gods, let's pretend our functions are now fully integrated, calling upon the ancient libraries of SQLite, PostgreSQL, or the like.

// Imagine these functions now talk to a database
// Through mystical portals like database/sql and pq

Our journey nears its end as we craft a simple CLI, a portal through which users can wield the power of the Four Sacred Commands. The main function becomes our command center:

func main() {
    // Here, in the real world, you'd loop and accept user input
    // For each command, invoking the appropriate magic
    fmt.Println("Welcome, traveler, to the Go Note Pad.")
    fmt.Println("Your commands are: Create, List, View, Delete.")
}

Congratulations, intrepid coder! You've journeyed far and learned much. But remember, the path of a coder is endless. There are always new spells to learn, dungeons to explore, and applications to build.

• Experiment with real databases.
• Enhance your CLI with libraries like cobra or urfave/cli.
• Maybe even conjure a GUI with fyne or gioui for your application.

May your bugs be few, and your coffee cup never empty. Happy coding! 🧙‍♂️💻🚀
