序一

The official “go/*” packages are important components of the Go programming language’s tools for analyzing Go programs. They are a core part of programs like gofmt and go vet. Understanding these packages not only improves a gopher’s programming skills, but can lead to building embedded scripts based on these packages.

Both Shushan Chai (chai2010@github) and Ben Shi (benshi001@github) are Go contributors, who have made many good commits to Go’s master branch.

This book authored by them introduces the functionalities and also analyzes the implementation of the “go/*” packages.

I recommend that Chinese gophers read it and benefit from the content. What’s more, I hope more Chinese gophers will make contributions to Go after reading it.

官方提供的“go/*”包是Go語言的重要組件，主要用于解析Go程序，同時是gofmt和go vet的核心。理解這些包不僅能讓Go語言程序員提升編程技能，還能幫助他們基于這些包構建自己的嵌入式腳本。

柴樹杉和史斌是Go語言的代碼貢獻者，他們都為Go語言貢獻了高質量的代碼，并融入了Go的主干分支。

他們創作的這本書介紹了“go/*”包的功能并分析了它的實現。

我向中國的Go語言開發者推薦這本書，希望你們能從這本書中獲益，更希望你們讀過這本書之后能為Go語言貢獻精彩的代碼。
