# linters 

## Overview

`linters` is a project that enables the integration of custom linting rules into the [golangci-lint](https://github.com/golangci/golangci-lint) framework. 

## Usage

Add to .golangci.yml 

```yml

    linters-settings:
    custom:
        custom-linters:
            path: <Path to the directory with libraries>
            original-url: git.frostfs.info/TrueCloudLab/linters


    linters:
        enable:
            custom-linters
```


## Installation

```bash
    git clone git.frostfs.info/TrueCloudLab/linters
    cd linters
    make lib OUT_DIR=<Path to the directory with libraries>
```
