Source: https://github.com/zerodha/gokiteconnect/blob/master/README.md

Command to fetch and install the Gokiteconnect Go client library using go get. This is the first step to integrating Kite Connect API in your Go applications.

```bash
go get github.com/zerodha/gokiteconnect/v4
```

--------------------------------

### Bash: Run Gokiteconnect Example

Source: https://github.com/zerodha/gokiteconnect/blob/master/README.md

Command to execute a basic example provided within the Gokiteconnect library's examples folder. This allows developers to quickly test the integration after updating API keys.

```bash
go run examples/connect/basic/connect.go
```

### Go: Authenticate and Fetch User Margins using Kite Connect

Source: https://github.com/zerodha/gokiteconnect/blob/master/README.md

Example Go code demonstrating how to create a Kite Connect client instance, generate a user session using an API secret and request token, set the access token, and retrieve user margins. It requires API keys and a request token obtained through the Kite Connect login flow.

```go
package main

import (
	"fmt"

	kiteconnect "github.com/zerodha/gokiteconnect/v4"
)

const (
	apiKey    string = "my_api_key"
	apiSecret string = "my_api_secret"
)

func main() {
	// Create a new Kite connect instance
	kc := kiteconnect.New(apiKey)

	// Login URL from which request token can be obtained
	fmt.Println(kc.GetLoginURL())

	// Obtained request token after Kite Connect login flow
	requestToken := "request_token_obtained"

	// Get user details and access token
	data, err := kc.GenerateSession(requestToken, apiSecret)
	if err != nil {
		fmt.Printf("Error: %v", err)
		return
	}

	// Set access token
	kc.SetAccessToken(data.AccessToken)

	// Get margins
	margins, err := kc.GetUserMargins()
	if err != nil {
		fmt.Printf("Error getting margins: %v", err)
	}
	fmt.Println("margins: ", margins)
}
```

--------------------------------

### Bash: Run Gokiteconnect Unit Tests

Source: https://github.com/zerodha/gokiteconnect/blob/master/README.md

Command to execute the unit tests for the Gokiteconnect Go library. This is a standard command for Go projects to verify the correctness of the codebase.

```bash
go test -v
```

--------------------------------

### Bash: Initialize Gokiteconnect Git Submodules

Source: https://github.com/zerodha/gokiteconnect/blob/master/README.md

Command to initialize and update git submodules for the Gokiteconnect project, typically required for fetching mock responses used in test cases during development.

```bash
git submodule update --init --recursive
```

### Go: Stream Live Market Data with Kite Ticker

Source: https://github.com/zerodha/gokiteconnect/blob/master/README.md

Go program demonstrating how to use the Kite Ticker to establish a WebSocket connection for streaming live market data. It includes setting up callbacks for connection events, errors, ticks, and order updates, and subscribing to specific instrument tokens.

```go
package main

import (
	"fmt"
	"time"

	kiteconnect "github.com/zerodha/gokiteconnect/v4"
	kitemodels "github.com/zerodha/gokiteconnect/v4/models"
	kiteticker "github.com/zerodha/gokiteconnect/v4/ticker"
)

var (
	ticker *kiteticker.Ticker
)

var (
	instToken = []uint32{408065, 112129}
)

// Triggered when any error is raised
func onError(err error) {
	fmt.Println("Error: ", err)
}

// Triggered when websocket connection is closed
func onClose(code int, reason string) {
	fmt.Println("Close: ", code, reason)
}

// Triggered when connection is established and ready to send and accept data
func onConnect() {
	fmt.Println("Connected")
	err := ticker.Subscribe(instToken)
	if err != nil {
		fmt.Println("err: ", err)
	}
	// Set subscription mode for the subscribed token
	// Default mode is Quote
	err = ticker.SetMode(kiteticker.ModeFull, instToken)
	if err != nil {
		fmt.Println("err: ", err)
	}

}

// Triggered when tick is recevived
func onTick(tick kitemodels.Tick) {
	fmt.Println("Tick: ", tick)
}

// Triggered when reconnection is attempted which is enabled by default
func onReconnect(attempt int, delay time.Duration) {
	fmt.Printf("Reconnect attempt %d in %fs\n", attempt, delay.Seconds())
}

// Triggered when maximum number of reconnect attempt is made and the program is terminated
func onNoReconnect(attempt int) {
	fmt.Printf("Maximum no of reconnect attempt reached: %d", attempt)
}

// Triggered when order update is received
func onOrderUpdate(order kiteconnect.Order) {
	fmt.Printf("Order: ", order.OrderID)
}

func main() {
	apiKey := "my_api_key"
	accessToken := "my_access_token"

	// Create new Kite ticker instance
	ticker = kiteticker.New(apiKey, accessToken)

	// Assign callbacks
	ticker.OnError(onError)
	ticker.OnClose(onClose)
	ticker.OnConnect(onConnect)
	ticker.OnReconnect(onReconnect)
	ticker.OnNoReconnect(onNoReconnect)
	ticker.OnTick(onTick)
	ticker.OnOrderUpdate(onOrderUpdate)

	// Start the connection
	ticker.Serve()
}
```
