🎯 Smart Completion

EmmyLua provides industry-leading intelligent code completion features, supporting not only basic function, variable, table field, and module completion, but also multiple innovative features.

🔧 Core Completion Features

🛣️ Path Completion System

🎪 Advanced Completion Features

• 🔧 Postfix: Type @ or . after variables to trigger expression completion
• 📝 Snippet: Built-in code snippets, future support for custom template system

💡 Tip: All completion features support fuzzy matching and smart sorting for a smoother coding experience.

💡 Code Hints

Intelligent mouse hover hint system that provides rich contextual information and code insights.

✨ Basic Hint Features

• 🔍 Variable Information: Type, scope, definition location
• ⚡ Function Signatures: Parameter types, return values, documentation comments
• 📊 Table Fields: Field types, access permissions, inheritance relationships
• 📦 Module Information: Export content, dependencies, version information

🚀 Advanced Features

local PI = 3.14159  -- Hover displays: const PI: number = 3.14159
local AREA = PI * 2 -- Hover displays: const AREA: number = 6.28318

💡 Pro Tip: Constant calculation supports complex mathematical expressions and string operations, helping you better understand code logic.

🔍 Code Diagnostics

Powerful static analysis system based on EmmyLua annotations, helping you discover potential issues during coding and maintain code quality.

⚙️ Diagnostic Control

📝 Comment Control

---@diagnostic disable: undefined-global
-- Disable undefined-global check in entire file

---@diagnostic disable-next-line: undefined-global
-- Disable check only for next line

⚙️ Configuration File Control

Fine-tune diagnostic behavior through configuration files:

{
  "diagnostics": {
    "disable": ["undefined-global", "unused"],
    "enable": [],
    "severity": {
      "undefined-global": "error",
      "unused": "warning"
    }
  }
}

📊 Code Navigation

Powerful code navigation system that allows you to quickly locate and browse code in large projects.

🗂️ Document Symbols

🔗 Code Navigation

🎯 Go to Definition

🔎 Find References

📍 Standard Reference Finding

• 🔍 Find All References: Find All References
• 🖱️ Quick Find: Ctrl + Left Click

🚀 Enhanced Reference Features

graph LR
    A[String References] --> B[Exact Matching]
    C[Fuzzy References] --> D[Smart Inference]
    E[Configuration Control] --> F[Optional Enable]

• 📝 String References: Find usage locations of string literals
• 🎯 Fuzzy References: Smart matching for undefined variables
• ⚙️ Configuration Control: Control enable status through configuration files

💡 Tip: Reference finding supports cross-file analysis and can accurately identify dependencies between modules.
