🔍 PR Review: LLGo Documentation

Todo List:

Gather context and read the modified documentation file
Analyze content for documentation quality and technical accuracy
Provide comprehensive review feedback
Submit final review

Review Summary

This PR adds comprehensive documentation explaining LLGo's Python compilation and runtime integration process. The content is well-structured and provides valuable technical insights into how LLGo handles Python dependencies, compilation, linking, and bundling.

Strengths

Comprehensive Coverage: The document thoroughly covers the entire Python integration pipeline from dependency detection to final packaging
Clear Structure: Well-organized sections with logical flow from high-level concepts to implementation details
Code Examples: Includes relevant Go code snippets that illustrate key concepts
Practical Value: Explains both the technical implementation and the practical benefits for end users
Comparative Analysis: Good comparison between C/C++ and Python integration approaches

Issues and Suggestions

Critical Issues

Code Reference Format Inconsistency (Line 27):
```
```418:424:llgo/internal/build/build.go
```
This format mixing line numbers with file path is non-standard. Consider using either:
- Standard markdown: ````go` // from llgo/internal/build/build.go:418-424```
- Or separate the reference: "From llgo/internal/build/build.go lines 418-424:"
Missing Newline at End (Line 166):
The file ends without a final newline character, which violates POSIX standards and may cause issues with some tools.

Documentation Quality Issues

Hard-coded Version References (Line 78):
```
inc := filepath.Join(pyenv.PythonHome(), "include", "python3.12")
```
The documentation hard-codes Python 3.12, which may become outdated. Consider using a placeholder like python3.x or explaining the version detection mechanism.
Incomplete Code Snippets (Lines 31-34):
```
case cl.PkgLinkIR, cl.PkgLinkExtern, cl.PkgPyModule:
    // ... 见下文
```
The comment "见下文" (see below) is vague. Either expand the code example or provide a more specific reference.
Inconsistent Comment Style:
- Line 72: Uses out := tmp.Name() + ".o" with inline comments
- Line 107: Uses // <exe_dir>/python/lib/... with block comments
  Standardize comment placement and style throughout.

Technical Accuracy Concerns

macOS-Specific Commands (Line 119):
```
_ = exec.Command("install_name_tool", "-id", "@rpath/"+filepath.Base(libDst), libDst).Run()
```
The error is explicitly ignored with _. Documentation should explain why error handling is omitted or if this is a simplification.
Incomplete Function Signatures (Lines 109, 124):
Functions like BundleOnedir and BuildOnefileBinary show incomplete implementations. Consider either:
- Providing complete examples
- Clearly marking them as simplified/pseudo-code
- Referencing actual source locations

Presentation Issues

Mixed Language Content: While the technical content is excellent, consider adding English abstracts for key sections to improve accessibility for international contributors.
Section Balance: The "一眼看懂的调用顺序" (Call Sequence) section is quite brief compared to others and could benefit from more detail or visual representation.

Recommendations

Fix the code reference format on line 27
Add final newline to the file
Use version placeholders instead of hard-coded Python versions
Expand incomplete code examples or mark them clearly as simplified
Standardize comment formatting throughout code blocks
Add error handling explanations where errors are ignored
Consider adding a glossary for technical terms like SSA/IR, rpath, etc.

Overall Assessment

This is a valuable addition to the documentation that provides deep technical insights into LLGo's Python integration. The content demonstrates strong understanding of the system architecture and will be helpful for developers working with LLGo. With the suggested improvements, this documentation will be even more effective.

The technical approach described is sound, and the step-by-step explanation makes complex integration concepts accessible. The comparison between C/C++ and Python handling is particularly insightful.

Summary of Changes

Hello @1351914167, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

此拉取请求新增了一份详细的文档，阐述了 LLGo（一个基于 LLVM 的 Go 编译器）如何实现 Python 编译与运行时的深度集成。该文档全面覆盖了从识别 Python 依赖到将带有 Python 能力的应用程序打包以便于分发的整个流程，确保用户无需预先安装 Python 环境即可运行 LLGo 编译的应用程序。同时，它也对比了 Python 与 C/C++ 在 LLGo 中的集成方式。

Highlights

LLGo 中 Python 编译与运行时集成: 详细阐述了 LLGo 如何集成 Python 的编译与运行时，涵盖了依赖识别、链接和初始化等关键环节。
打包能力 (Bundle): 介绍了 LLGo 的 bundle 功能，允许将 Python 与应用程序一起打包，实现“拿来就跑”的部署，提供了目录式和单文件自解压两种形式。
与 C/C++ 的对比: 强调了 LLGo 在处理 C/C++ 和 Python 依赖时的异同，特别是在运行时初始化和环境准备方面的差异。
详细构建流程: 概述了 LLGo 中 Python 集成的关键构建步骤，包括预构建环境准备、链接阶段的注入和 rpath 处理。
