調(diào)試Go 應用的主要工具是Delve（dlv），它專為Go 設計，支持設置斷點、變量檢查、遠程調(diào)試，並與VS Code 和GoLand 等IDE 集成；其他工具包括1.GDB（基礎調(diào)試但功能有限）2.打印日誌（簡單有效）3.pprof（分析性能問題）4.trace 工具（查看執(zhí)行事件）；多數(shù)現(xiàn)代編輯器如VS Code 和GoLand 均可通過插件實現(xiàn)基於Delve 的調(diào)試集成。

When it comes to debugging Go applications, there are several solid tools available that cater to different needs — from command-line debuggers to full IDE integrations. The most popular and powerful one is Delve, but it's definitely not the only option.

Using Delve – The Go Debugger

Delve (or dlv ) is the go-to debugger for Go applications. It's specifically designed for Go, so it understands the language runtime and can handle things like goroutines, channels, and other Go-specific constructs better than generic debuggers.

Here's how you typically use it:

• Install with: go install github.com/go-delve/delve/cmd/dlv@latest
• Start debugging by running dlv debug in your project directory
• You can set breakpoints, inspect variables, step through code, and even evaluate expressions while paused

Delve also supports remote debugging, which is super handy if you're debugging a service running on a different machine or container. Just start the server with dlv --listen=:2345 --headless=true debug , and connect from another instance of dlv or an IDE.

It works well with VS Code and GoLand via plugins, giving you a graphical interface without leaving your editor.

Alternative Debugging Tools

While Delve is the most feature-complete, there are other tools depending on what you're trying to do:

• GDB (GNU Debugger) : Technically usable for Go, but limited support for Go-specific features. It might work fine for basic debugging, but it's outdated compared to Delve.
• Print Statements / Logging : Not fancy, but still effective. Sometimes adding a few strategic log lines beats setting up a full debugging session.
• pprof : While not a traditional debugger, net/http/pprof helps analyze performance issues, CPU and memory usage, and even look into active goroutines — useful when debugging hangs or leaks.
• Trace tool : go tool trace gives you insight into execution events over time, helping understand scheduling, blocking, or contention issues.

Each has its own niche, and sometimes combining them gives the clearest picture.

Integrating with IDEs and Editors

If you prefer working inside an IDE or editor, most modern setups support debugging Go apps directly through built-in or plugin-based integration:

• VS Code : With the official Go extension, you get full debugging support using Delve. Just set breakpoints and hit F5.
• GoLand : JetBrains' Go IDE offers deep integration out of the box, including smart variable evaluation and stack inspection.
• LiteIDE / Vim / Emacs : These have varying levels of support, usually through custom configurations that hook into dlv .

Setting this up usually involves installing the right plugin and making sure dlv is in your path. Once configured, you get a much smoother experience than pure CLI debugging.

So yeah, Delve is the main player here, but knowing the alternatives and integrations makes debugging Go apps way more flexible. Depending on your setup and problem, switching between tools can save time and headaches.基本上就這些。
