**D**efer **L**oop **L**inter

A simple linter to find `defer` statements inside of for loops in Go source.

## Other Works

See [Issue #12](https://github.com/gsquire/dll/issues/12) for an existing tool (`staticcheck`).

## Why?

It's often erroneous to use `defer` inside of a loop as it can lead to memory leaks or other

unintended behavior. It can also be easy to miss this in a code review as using `defer` to

close sockets or files is a common Go idiom. This tool aims to point these out by simply printing

the line of a `defer` statement when it is found inside of a loop.

## Install

```sh

go get github.com/gsquire/dll

```

## Usage

```sh

dll source.go

dll *.go

```
