Question 1

How do I install Delve on macOS?

Accepted Answer

You can install Delve on macOS using Homebrew with `brew install delve`, or via Go tools with `go install github.com/go-delve/delve/cmd/dlv@latest`. Ensure you have the necessary permissions and dependencies, as detailed in the installation guide.

Question 2

What's better for Go debugging: Delve or GDB?

Accepted Answer

Delve is generally preferred over GDB for Go because it understands Go's runtime, goroutines, and data structures natively, whereas GDB is a general-purpose debugger that may not handle Go-specific features as well. Delve's Go-specific design makes it more reliable for concurrent debugging.

Question 3

How can I debug a running Go web server with Delve?

Accepted Answer

Use `dlv attach <pid>` to attach to a running process by its PID, or start the server with `dlv debug` and set breakpoints. This allows inspection without restarting, useful for long-running services as covered in the CLI documentation.

Question 4

Does Delve work with Docker containers?

Accepted Answer

Yes, Delve can debug Go programs inside Docker containers by using flags like `--headless` and exposing ports, but it requires careful configuration to ensure the debugger can communicate with the containerized application, as noted in community discussions.

Question 5

How to set up Delve with Visual Studio Code?

Accepted Answer

Install the Go extension for VS Code, which integrates Delve automatically. Configure launch settings in `.vscode/launch.json` to specify breakpoints and commands, leveraging the plugin support documented in EditorIntegration.md.

Question 6

What are the most common Delve commands for beginners?

Accepted Answer

Start with `dlv debug` to launch a program, `break` to set breakpoints, `continue` to resume execution, and `print` to inspect variables. The CLI getting started guide provides examples to help new users get up to speed quickly.
