|
A simple linter to find `defer` statements inside of for loops in Go source.
|
|
|
|
This is a fork from [gsquire/dll](https://github.com/gsquire/dll) with support for concurrent analyses. The goal of it was to practice the work with goroutines.
|
|
|
|
|
|
## 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
|
|
```
