⍰ Thank you! In my current Cursor workspace, please generate a golang testsuite for a Unix 'wc' tool clone, then implement the application as well.

ⓘ Sure! Below is a simple implementation of a Unix wc (word count) tool clone in Go, along with a test suite to verify its functionality.

Go Application Implementation

// path/to/wc.go
package main

import (
    "bufio"
    "fmt"
    "os"
    "strings"
)

func main() {
    if len(os.Args) < 2 {
        fmt.Println("Usage: wc <file>")
        return
    }

    fileName := os.Args[1]
    count, err := countWords(fileName)
    if err != nil {
        fmt.Println("Error:", err)
        return
    }

    fmt.Printf("Word count: %d\n", count)
}

func countWords(fileName string) (int, error) {
    file, err := os.Open(fileName)
    if err != nil {
        return 0, err
    }
    defer file.Close()

    scanner := bufio.NewScanner(file)
    wordCount := 0

    for scanner.Scan() {
        line := scanner.Text()
        wordCount += len(strings.Fields(line))
    }

    if err := scanner.Err(); err != nil {
        return 0, err
    }

    return wordCount, nil
}

Go Test Suite

// path/to/wc_test.go
package main

import (
    "os"
    "testing"
)

func TestCountWords(t *testing.T) {
    // Create a temporary file for testing
    tempFile, err := os.CreateTemp("", "testfile.txt")
    if err != nil {
        t.Fatal(err)
    }
    defer os.Remove(tempFile.Name()) // Clean up

    // Write test content to the file
    content := "Hello World\nThis is a test file.\n"
    if _, err := tempFile.WriteString(content); err != nil {
        t.Fatal(err)
    }
    tempFile.Close()

    // Test the countWords function
    expected := 7
    actual, err := countWords(tempFile.Name())
    if err != nil {
        t.Fatal(err)
    }

    if actual != expected {
        t.Errorf("Expected %d, got %d", expected, actual)
    }
}

Explanation

1. Application (wc.go): The main function checks for command-line arguments and calls countWords to count the words in the specified file. The countWords function reads the file line by line, counts the words using strings.Fields, and returns the total count.
2. Test Suite (wc_test.go): The test suite creates a temporary file with predefined content. It tests the countWords function to ensure it returns the correct word count. You can run the tests using the command:

go test path/to/

Feel free to modify the implementation or tests as needed! If you have any specific requirements or additional features you'd like to include, let me know!
