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


    linters:
        enable:
            truecloudlab-linters
```


## Installation

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

## Available linters

| Name                    | Description                                                                                                                   |
|-------------------------|-------------------------------------------------------------------------------------------------------------------------------|
| [noliteral](#noliteral) | The tool prohibits the use of literal string arguments in logging functions.                                                   |
| [useStrconv](#useStrconv)         | The `useStrconv` linter recommends the utilization of `strconv` over `fmt` when performing string conversions of primitive data types. Detailed guidelines can be found in the [official Uber Go Style Guide](https://github.com/uber-go/guide/blob/master/style.md#prefer-strconv-over-fmt). |
