Celper is a brutal, real-time memory leak detector for VS Code. Built for developers learning C, it ensures you never leave a malloc hanging. If you forget to free(), Celper roasts you in the "Problems" tab.
🔥 Key Features
Variable Tracking: Uses a Map<string, number[]> to track every specific allocation.
The "Double Malloc" Catch: Flags you if you overwrite a pointer before freeing the old memory.
Fatal Return Check: Prevents you from return-ing out of a function while memory is still leaked.
Zero Sugarcoating: Direct, unhinged error messages that tell it like it is.
🛠️ How it Works (The Logic)
Celper doesn't just scan for words; it tracks the lifecycle of your pointers.
Action
What Celper Does
malloc()
Pushes the line number to the variable's "Active Stack".
free()
Pops the latest line number. Balance restored.
return
Checks if any stacks are non-empty. If yes → FATAL ERROR.
End of File
Scans for any orphaned allocations left over.
🚀 Installation & Dev
To run this locally and help Celper roast more code:
Clone the repo: git clone https://github.com/RelRashica/Celper.git
Install dependencies: npm install
Press F5 to open the Extension Development Host.
Open any .c file and start leaking memory!
⚠️ Known Limitations
Disclaimer: Celper is a static scanner. It’s perfect for learning and simple scripts, but it doesn't track pointers across different files or complex function arguments... yet.
