Go代碼可通過內(nèi)置工具自動格式化，確保遵循官方格式規(guī)范；首先使用gofmt進行基礎(chǔ)格式化，執(zhí)行g(shù)ofmt -w filename.go可格式化單個文件，gofmt -w .可格式化整個包；其次推薦使用go fmt ./...命令，它是gofmt的封裝，能更好集成模塊并遞歸格式化項目所有文件；進一步可采用goimports工具，需先通過go install golang.org/x/tools/cmd/goimports@latest安裝，再運行g(shù)oimports -w .，它不僅能格式化代碼，還能智能管理導(dǎo)入語句，自動刪除未使用包并正確排序；最后建議在編輯器中集成自動格式化功能，如VS Code安裝Go擴展、Vim使用vim-go或coc-go插件、GoLand默認(rèn)支持，均可在保存時自動格式化并推薦啟用goimports；總之應(yīng)定期運行g(shù)o fmt ./...保持代碼風(fēng)格一致，并結(jié)合編輯器實現(xiàn)自動化。

Go code can be automatically formatted using built-in tools that follow the official Go formatting conventions. The most common and recommended way is using gofmt, but there are also higher-level tools like go fmt and goimports that make the process even easier.

Use gofmt for basic formatting

gofmt is a command-line tool that comes with the Go installation. It reformats Go source code according to standard conventions (like indentation, spacing, and parentheses placement).

To format a single file:

gofmt -w filename.go

To format an entire package:

gofmt -w .

The -w flag writes the changes back to the file(s). Without it, gofmt just prints the formatted output to stdout.

Run go fmt (easier and integrates with modules)

go fmt is a wrapper around gofmt that works better with Go modules and project structures.

To format all files in the current package and subdirectories:

go fmt ./...

This command recursively formats all Go files in your project. It’s commonly used before commits to ensure consistent style.

Improve imports with goimports

While gofmt handles code layout, goimports (a tool by Google) also manages import statements—removing unused ones and sorting them correctly (including separating standard library imports from third-party ones).

Install it first:

go install golang.org/x/tools/cmd/goimports@latest

Then use it like gofmt:

goimports -w .

Many developers prefer goimports over gofmt because it handles imports more intelligently.

Integrate with your editor

Most modern editors support automatic Go formatting on save:

• VS Code: Install the Go extension. It automatically formats code on save if configured.
• Vim/Neovim: Use plugins like vim-go or coc-go to run gofmt or goimports on save.
• GoLand: Built-in support; enables formatting by default.

Check your editor settings to enable:

• Format on save
• Use goimports instead of gofmt (recommended)

Summary

• Use go fmt ./... regularly—it's simple and official.
• Consider goimports for smarter import handling.
• Set up your editor to format automatically.

Basically, Go makes formatting effortless—just run one command and your code will always look consistent.
