Go

yaml

trace:
  enabled_languages:
    - .go
  exclude_patterns:
    - "*_test.go"
    - "mock_*.go"
    - "*_mock.go"

Trace accuracy: Excellent. Go's explicit syntax makes tracing very reliable.

追踪准确性： 良好。委托和事件可能会被部分追踪。

Multi-Language Projects

多语言项目

For projects with multiple languages:

yaml

trace:
  enabled_languages:
    # Backend (Go)
    - .go
    # Frontend (TypeScript)
    - .ts
    - .tsx
    # Shared (SQL, etc.)
    - .sql  # Index only

  exclude_patterns:
    - "*_test.go"
    - "*.spec.ts"

对于包含多种语言的项目：

yaml

trace:
  enabled_languages:
    # 后端（Go）
    - .go
    # 前端（TypeScript）
    - .ts
    - .tsx
    # 共享（SQL等）
    - .sql  # 仅索引

  exclude_patterns:
    - "*_test.go"
    - "*.spec.ts"

Index vs Trace Explained

索引与追踪说明

Index (Semantic Search)

索引（语义搜索）

Works on any text file
Code is chunked and embedded
Enables semantic search
No language-specific parsing required

适用于任何文本文件
代码会被分块并嵌入
支持语义搜索
无需特定语言解析

Trace (Call Graphs)

追踪（调用图）

Requires language-specific parsing
Extracts function definitions and calls
Builds caller/callee relationships
Uses regex (fast) or tree-sitter (precise)

需要特定语言解析
提取函数定义和调用关系
构建调用者/被调用者关系
使用正则表达式（快速）或tree-sitter（精确）

Trace Modes by Language

按语言划分的追踪模式

Language	Fast Mode	Precise Mode

JavaScript	✅	✅
TypeScript	✅	✅
Python	✅	✅
PHP	✅	✅
C/C++	✅	✅
Rust	✅	✅
Zig	✅	✅
C#	✅	✅
Java	✅	✅
Pascal	✅	⚠️ Limited

语言	快速模式	精确模式

Adding Custom Extensions

添加自定义扩展名

If you have non-standard extensions, they'll be indexed but not traced:

yaml

undefined

如果你有非标准扩展名，它们会被索引但不会被追踪：

yaml

undefined

Custom extension files will be indexed

自定义扩展名文件会被索引

ignore:

Only add patterns for files you DON'T want indexed

"*.generated.go"

undefined

ignore:

仅添加你不想被索引的文件模式

"*.generated.go"

undefined

File Type Detection

文件类型检测

GrepAI uses file extensions for detection. It does NOT use:

Shebangs (
```
#!/usr/bin/env python
```
)
File content analysis
.editorconfig

GrepAI使用文件扩展名进行检测。它不使用：

Shebang（
```
#!/usr/bin/env python
```
）
文件内容分析
.editorconfig

Unsupported Languages (Index Works, No Trace)

不支持追踪的语言（索引可用）

These languages can be indexed for semantic search but don't have trace support:

Ruby
Swift
Kotlin
Scala
Elixir
Clojure
Haskell
OCaml
F#
Erlang
R
Julia
Perl
Groovy

Workaround: Use semantic search to find code, then manually trace.

这些语言可被索引用于语义搜索，但没有追踪支持：

Ruby
Swift
Kotlin
Scala
Elixir
Clojure
Haskell
OCaml
F#
Erlang
R
Julia
Perl
Groovy

解决方法： 使用语义搜索查找代码，然后手动追踪。

Best Practices

最佳实践

Enable only needed languages: Faster trace building
Exclude test files: Cleaner trace results
Use precise mode for accuracy: When trace results seem incomplete
Match your tech stack: Configure based on your actual languages

仅启用需要的语言： 加快追踪构建速度
排除测试文件： 获得更清晰的追踪结果
使用精确模式提高准确性： 当追踪结果不完整时
匹配你的技术栈： 根据实际使用的语言进行配置

Common Issues

常见问题

❌ Problem: Files not being indexed ✅ Solution: Check file isn't in ignore patterns

❌ Problem: Trace missing for language ✅ Solution: Ensure language is in

enabled_languages

❌ Problem: Wrong language detected ✅ Solution: GrepAI uses extensions only; rename files if needed

❌ 问题： 文件未被索引 ✅ 解决方案： 检查文件是否在忽略模式中

❌ 问题： 语言的追踪缺失 ✅ 解决方案： 确保语言在

enabled_languages

中

❌ 问题： 检测到错误的语言 ✅ 解决方案： GrepAI仅使用扩展名；如有需要请重命名文件
