## What it is
A free open-source Chinese-language book (《Go语言定制指南》, formerly Go语法树入门) teaching Go's abstract syntax tree via the go/ast and go/token packages, plus parser tools like goyacc. It is a learning resource for building Go language tooling and toy compilers.

## Use cases
- learn go/ast to parse Go source code
- build custom Go code analysis tools
- write a toy compiler for a Go-like language
- understand how go fmt and go doc work internally
- learn goyacc and parser generation
- customize the Go language via syntax trees

## When to choose
- you want a free, structured introduction to Go's AST packages
- you are building Go linters, formatters, or code generators
- you want to learn compiler basics with Go as the target language

## When to avoid
- you need a ready-made tool or library rather than a book
- you need content in English
- you want a general Go language tutorial rather than AST/compiler topics

## Facets
- artifact type: learning-resource
- maturity: active
- function: parser, compiler, documentation, programming-language
- domain: tutorials, programming-languages, parsers, compilers, developer-tools
- platform: go, cross-platform
- tags: go-ast, syntax-tree, goyacc, llvm, free-book, chinese
