# eleme/Stinger

Stinger is a high-efficiency library with great compatibility, for aop in Objective-C,  using libffi instead of Objective-C message forwarding. It is 20+ times faster than the Aspects, from message-sending to Aspect-oriented code ends.

## What it is
Stinger is a high-performance Objective-C library for aspect-oriented programming (AOP) that hooks into existing methods before/instead/after execution using libffi instead of message forwarding. It claims to be 20+ times faster than the Aspects library while handling super calls automatically.

## Use cases
- hook into existing Objective-C methods without subclassing
- add logging or analytics code before/after method calls
- replace method implementations at runtime for testing or patching
- avoid fragile manual method swizzling
- run a block once and auto-remove the hook
- manage and remove named hooks by identifier

## When to choose
- you need AOP-style method hooking in Objective-C with better performance than Aspects
- you want a safer, higher-level API over raw method swizzling
- you need fine-grained control over hook lifecycle with identifiers

## When to avoid
- you are working in Swift-only codebases without Objective-C interop
- you need AOP in languages other than Objective-C
- your project requires actively maintained libraries with frequent updates
