Mago 0.9.0 introduces deeper undefined reference checks, a brand-new mago find command for locating symbol references, and a new rule to catch unnecessary hash comments (#️⃣).
🔥 Major Changes
1️⃣ Expanded Undefined Member Checks & Improved Severity Handling
Mago now detects more cases of undefined methods, functions, constants, and enum cases, preventing runtime errors before they happen.
New Checks Added:
✅ Calling an undefined, non-static, or abstract static method is now flagged
✅ Creating a closure for an undefined function is now reported
✅ Class-like constants & enum cases that are undefined are now detected
✅ Static method calls on traits (deprecated in PHP 8.2+) now trigger warnings
✅ Fix: Severity levels now correctly respect user configurations
🔎 Why This Matters: These changes ensure Mago catches more real-world issues in PHP codebases, helping developers avoid hard-to-debug runtime errors.
2️⃣ New CLI Command: mago find 🔍
A powerful new command has landed! mago find [query] lets you search for symbol references (e.g., functions, classes, traits, enum cases, and more) across your PHP project instantly.
How It Works
- Find where a symbol is used:
mago find SomeClass - Search for function references:
mago find some_function - Locate all trait usages:
mago find SomeTrait - Works in user-defined & external sources
🎯 Built for speed & accuracy, this feature is ideal for navigating large codebases, understanding dependencies, and future LSP integrations.
