### Install Maintidx for Go < 1.16

Source: https://github.com/yagipy/maintidx/blob/main/README.md

Use 'go get' to install a specific version of the maintidx command-line tool for Go versions prior to 1.16.

```shell
go get -u github.com/yagipy/maintidx/cmd/maintidx@v1.0.0
```

--------------------------------

### Install Maintidx for Go 1.16+

Source: https://github.com/yagipy/maintidx/blob/main/README.md

Use 'go install' to install the maintidx command-line tool for Go versions 1.16 and newer.

```shell
go install github.com/yagipy/maintidx/cmd/maintidx@v1.0.0
```

--------------------------------

### Run Maintidx with 'go run'

Source: https://github.com/yagipy/maintidx/blob/main/README.md

Execute the maintidx tool using 'go run' for projects where the tool is not globally installed. This command runs the tool directly from its source path.

```shell
go run github.com/yagipy/maintidx/cmd/maintidx ./...
```

--------------------------------

### Run golangci-lint with Maintidx Enabled

Source: https://github.com/yagipy/maintidx/blob/main/README.md

Execute golangci-lint to run all enabled linters, including maintidx, based on your configuration.

```shell
golangci-lint run

```

--------------------------------

### Run Maintidx with 'go vet'

Source: https://github.com/yagipy/maintidx/blob/main/README.md

Integrate maintidx with the 'go vet' command by specifying it as a vet tool. This allows 'go vet' to perform maintainability index checks.

```shell
go vet -vettool=`which maintidx` ./...
```

--------------------------------

### Run Maintidx Standalone

Source: https://github.com/yagipy/maintidx/blob/main/README.md

Execute the maintidx tool directly on your Go project files. It analyzes all files within the specified directory.

```shell
maintidx ./...
```

--------------------------------

### Enable Maintidx in golangci-lint

Source: https://github.com/yagipy/maintidx/blob/main/README.md

Configure golangci-lint to use maintidx by enabling it in the configuration file. This allows for integrated code analysis.

```yaml
# Add maintidx to enable linters.
linters:
  enable:
    - maintidx

linters-settings:
  maintidx:
    # Show functions with maintainability index lower than N.
    # A high index indicates better maintainability (it's kind of the opposite of complexity).
    # Default: 20
    under: 100
```

--------------------------------

### Maintidx CLI Flag: -under

Source: https://github.com/yagipy/maintidx/blob/main/README.md

The '-under' flag allows you to filter the output to show only functions with a maintainability index below a specified integer value. The default value is 20.

```shell
Flags:
  -under int
    	show functions with maintainability index < N only. (default 20)
```
