**IPATool is implemented entirely in Go (Golang) and requires Go 1.25.0 to compile from source.**

The `majd/ipatool` repository is a command-line utility for downloading and searching iOS applications from the Apple App Store. If you are investigating what programming language IPATool is written in, the codebase follows standard Go conventions, utilizing a `go.mod` module file and the Cobra CLI framework for command management.

## Identifying the Programming Language from Source

### The go.mod Module Declaration

The definitive proof that IPATool is written in Go resides in the repository root. The `go.mod` file declares the module path and specifies the Go version required for compilation. According to the source analysis, this file mandates `go 1.25.0`, establishing the minimum toolchain version needed to build the project. This module file also tracks external dependencies using Go's native semantic versioning and checksum system.

### Go Source File Organization

The repository structure adheres to idiomatic Go project layouts. The entry point is [`main.go`](https://github.com/majd/ipatool/blob/main/main.go), which initializes the application and launches the Cobra command hierarchy. Subcommands such as `auth`, `search`, and `download` reside under the `cmd/` directory, each implemented in separate `.go` files. Low-level App Store protocol logic is encapsulated in `internal/sap/unicorn/`, while reusable utilities for ZIP handling and string manipulation live in `pkg/util/`. The exclusive use of `.go` file extensions throughout these directories confirms the implementation language.

## Building IPATool from Go Source

To compile IPATool, ensure your Go installation is version 1.25.0 or later. Execute the following commands in your terminal:

```bash

# Clone the repository

git clone https://github.com/majd/ipatool.git
cd ipatool

# Build the executable using the Go toolchain

go build -o ipatool ./...

```

Once built, you can interact with the App Store using the compiled binary:

```bash

# Search the App Store for "Spotify"

./ipatool search Spotify --platform iphone

# Download a specific app by bundle identifier

./ipatool download -b com.spotify.client -o spotify.ipa --platform iphone

```

These commands demonstrate how the Go-based binary interfaces with Apple's services without requiring external runtime dependencies.

## Key Go Files and Architecture

Understanding the codebase requires familiarity with these critical Go files:

- **`go.mod`**: Declares the module path, Go version 1.25.0, and dependency requirements.
- **[`main.go`](https://github.com/majd/ipatool/blob/main/main.go)**: The application entry point that sets up the Cobra command structure.
- **`cmd/`**: Implements CLI subcommands including authentication, search, and download functionality.
- **`internal/sap/unicorn/`**: Handles low-level App Store protocol interactions in Go.
- **`pkg/util/`**: Provides utility helpers for operations like ZIP extraction and string processing.

This organization follows Go's standard project layout, separating executable commands from internal implementation details and public library code.

## Summary

- IPATool is written in **Go (Golang)**, confirmed by the presence of `go.mod` and `.go` source files.
- The project requires **Go 1.25.0** according to the module declaration in the repository root.
- The **Cobra** framework manages the CLI command structure, initialized from [`main.go`](https://github.com/majd/ipatool/blob/main/main.go).
- Source code is organized using standard Go conventions with `cmd/`, `internal/`, and `pkg/` directories.

## Frequently Asked Questions

### Is IPATool written in Go?

Yes, IPATool is written entirely in Go. The repository contains a `go.mod` file that declares the module and specifies Go version 1.25.0, and all source files use the `.go` extension.

### What version of Go does IPATool require?

The `go.mod` file explicitly requires **Go 1.25.0**. You must have this version or a compatible later version installed to successfully build the binary from source.

### Can I build IPATool from source?

Yes, you can build IPATool from source using the standard Go toolchain. Clone the `majd/ipatool` repository and run `go build -o ipatool ./...` to compile the executable. No additional build systems like Make or CMake are required.

### What CLI framework does IPATool use?

IPATool uses the **Cobra** library for command-line interface management. The [`main.go`](https://github.com/majd/ipatool/blob/main/main.go) file serves as the entry point that initializes the Cobra command hierarchy to handle subcommands like `search`, `download`, and `auth`.
