- Alternatively, open the Extensions view (Ctrl+Shift+X / Cmd+Shift+X) and search for "ThinkCode Go"
Install Go:
- Ensure Go is installed on your system
- ThinkCode will detect the Go installation automatically
- Configure Go version in settings if needed
Project Configuration:
- ThinkCode supports standard Go project structures
- Automatically recognizes go.mod files for module support
- Configures the Go environment variables
Create a New Project:
- Command Palette (Ctrl+Shift+P / Cmd+Shift+P)
- Type "ThinkCode: Create New Project"
- Select Go from template categories
- Choose from templates:
  - Basic Go application
  - Go module
  - Web application (Gin, Echo, etc.)
  - RESTful API service
  - gRPC service

Code Intelligence

ThinkCode provides advanced intelligence for Go:

Auto-Completion: Context-aware suggestions for:
- Functions and methods
- Struct fields
- Package imports
- Variables
Type Information: Detailed type information with tooltips
Signature Help: Parameter info for functions
Quick Documentation: Access godoc directly in the editor

Example of Go code with intelligent assistance:

// ThinkCode provides intelligent assistance for Go
package main
 
import (
	"fmt"
	"time"
)
 
// Person represents a person with name and birth date
type Person struct {
	Name     string
	BirthDate time.Time
}
 
// Age calculates the person's age in years
func (p Person) Age() int {
	now := time.Now()
	years := now.Year() - p.BirthDate.Year()
	
	// Adjust age if birthday hasn't occurred yet this year
	birthDay := time.Date(now.Year(), p.BirthDate.Month(), p.BirthDate.Day(), 0, 0, 0, 0, time.Local)
	if now.Before(birthDay) {
		years--
	}
	
	return years
}
 
func main() {
	// ThinkCode provides intelligent completion
	person := Person{
		Name:     "John Doe",
		BirthDate: time.Date(1990, time.January, 15, 0, 0, 0, 0, time.UTC),
	}
	
	fmt.Printf("%s is %d years old\n", person.Name, person.Age())
}

    "grouping": ["std", "local", "other"]  // Import grouping order
  }
}

AI-Powered Development Features

Smart Code Generation

Generate Go code with natural language prompts:

Function Generation:

Add a comment describing function purpose
Press Alt+I / Option+I for AI implementation

Example:

// Generate a function that returns paginated results from a slice
// Press Alt+I here and ThinkCode generates the implementation
func paginate[T any](items []T, page, pageSize int) []T {
    if page < 1 || pageSize < 1 {
        return []T{}
    }
    
    startIndex := (page - 1) * pageSize
    if startIndex >= len(items) {
        return []T{}
    }
    
    endIndex := startIndex + pageSize
    if endIndex > len(items) {
        endIndex = len(items)
    }
    
    return items[startIndex:endIndex]
}

Struct Generation:
- Describe struct purpose in a comment
- ThinkCode generates a complete type with fields and methods
Test Generation:
- Select function to test
- Right-click and select "Generate Test"
- ThinkCode generates table-driven tests for the function

Code Refactoring

AI-assisted refactoring capabilities:

Extract Function: Extract code into a new function
Rename Symbol: Intelligently rename variables, functions, and types
Convert to Interface: Extract interface from concrete type
Fill Struct: Complete struct initialization
Generate Constructor: Create constructor functions

Access refactoring tools:

Right-click in editor
Select "Refactor" menu
Choose desired refactoring operation

Documentation Assistant

Generate and maintain Go documentation:

Comment Generation: Auto-generate godoc-style comments
Example Code: Generate example usage code
README Creation: Generate project documentation
API Documentation: Create API reference documentation

Example of AI-assisted documentation:

// Place cursor here and use Command Palette > "Generate Documentation"
// ProcessItems takes a collection of items and processes them according to the provided options.
// It applies the transformer function to each item that passes the filter check.
// If parallel is true, processing will be distributed across multiple goroutines.
//
// The function returns:
//  - A slice of transformed items that passed the filter
//  - An error if any individual transformation fails
//
// Processing stops on the first error encountered. If you need to collect all errors,
// use ProcessItemsCollectErrors instead.
//
// Example usage:
//
//     items := []int{1, 2, 3, 4, 5}
//     filter := func(i int) bool { return i%2 == 0 }
//     transformer := func(i int) (string, error) { return fmt.Sprintf("Value: %d", i*i), nil }
//     
//     results, err := ProcessItems(items, filter, transformer, true)
//     if err != nil {
//         log.Fatalf("Processing failed: %v", err)
//     }
//     
//     // results contains: ["Value: 4", "Value: 16"]
func ProcessItems[T any, R any](
    items []T,
    filter func(T) bool,
    transformer func(T) (R, error),
    parallel bool,
) ([]R, error) {
    // Implementation...
}
