Go 代码检查工具 golangci-lint

一、介绍

golangci-lint 是一个代码检查工具的集合,聚集了多种 Go 代码检查工具,如 golintgo vet 等。

优点:

  • 运行速度快
  • 可以集成到 vscode、goland 等开发工具中
  • 包含了非常多种代码检查器
  • 可以集成到 CI 中
  • 这是包含的代码检查器列表:Linters

二、安装

golangci-lint 官方不建议使用 go get 方式安装,推荐使用二进制安装。

MacOS

直接使用 homebrew 安装:

brew install golangci-lint
brew upgrade golangci-lint

Linux 和 Windows

# binary will be $(go env GOPATH)/bin/golangci-lint
curl -sSfL https://raw.githubusercontent.com/Goci/golangci-lint/master/install.sh | sh -s -- -b $(go env GOPATH)/bin v1.42.1

golangci-lint --version

golangci-lint 将会被安装到 GOPATH/bin 目录中,如果此目录不在环境变量路径中需要加上。

三、使用方式

命令行

在项目根目录下执行以下命令检查整个项目的代码:

golangci-lint run

其等价于:

golangci-lint run ./...

或者可以指定检查某个目录下的代码文件,指定目录时不会递归分析其子目录,要递归分析其子目录需要加上 /…:

golangci-lint run dir1 dir2/... dir3/file1.go

在没有配置文件时,golangci-lint 会使用默认的代码检查器进行检查。

使用以下命令,可以查看默认启用和关闭了哪些检查器:

golangci-lint help linters

四、集成 IDE

1. Visual Studio Code

在 vscode 配置文件中新增以下内容:

"go.lintTool":"golangci-lint",
"go.lintFlags": [
  "--fast"

golangci-lint 会自动查找项目中的 .golangci.yml 配置文件,不用额外配置。

2. Goland

  1. 安装插件 Go Linter

可以在 Goland 内插件市场搜索 Go Linter 直接安装。

  1. 配置 File Watchers

在 Goland 配置页面的 工具 -> File Watchers 进行配置。
点 + 按钮,选择 golangci-lint 创建。

五、排除代码检查

  1. 有时候有部分代码因为各种原因不能通过代码检查,也不能修改,可以使用注释跳过代码检查。如下所示:

    var bad_name int //nolint
    var bad_name int //nolint:golint,unused
    
  2. 可以排除一整块代码:

    //nolint
    func allIssuesInThisFunctionAreExcluded() *string {
      // ...
    }
     
    //nolint:govet
    var (
      a int
      b int
    )
    
  3. 一整个文件:

    //nolint:unparam
    package pkg
    

六、配置文件

golangci-lint 会自动在当前目录下查找以下名称的配置文件:

.golangci.yml
.golangci.yaml
.golangci.toml
.golangci.json

配置启用的代码选择器

linters:
  disable-all: true
  enable:
    - megacheck
    - govet
  enable-all: true
  disable:
    - maligned
    - prealloc
  presets:
    - bugs
    - unused
  fast: false

示例配置
以下是官方给出的配置文件示例,包含了可以设置的选项和选项的默认值:

# This file contains all available configuration options
# with their default values.
 
# options for analysis running
run:
  # default concurrency is a available CPU number
  concurrency: 4
 
  # timeout for analysis, e.g. 30s, 5m, default is 1m
  timeout: 1m
 
  # exit code when at least one issue was found, default is 1
  issues-exit-code: 1
 
  # include test files or not, default is true
  tests: true
 
  # list of build tags, all linters use it. Default is empty list.
  build-tags:
    - mytag
 
  # which dirs to skip: issues from them won't be reported;
  # can use regexp here: generated.*, regexp is applied on full path;
  # default value is empty list, but default dirs are skipped independently
  # from this option's value (see skip-dirs-use-default).
  # "/" will be replaced by current OS file path separator to properly work
  # on Windows.
  skip-dirs:
    - src/external_libs

  # default is true. Enables skipping of directories:

  skip-dirs-use-default: true
 
  # which files to skip: they will be analyzed, but issues from them
  # won't be reported. Default value is empty list, but there is
  # no need to include all autogenerated files, we confidently recognize
  # autogenerated files. If it's not please let us know.
  # "/" will be replaced by current OS file path separator to properly work
  # on Windows.
  skip-files:

  # to go.mod are needed. This setting is most useful to check that go.mod does
  # not need updates, such as in a continuous integration and testing system.
