# Qlty CLI
Qlty CLI is a multi-language code linter, auto-formatter, and security scanner.
Engineering teams use Qlty CLI for static analysis and auto-formatting of all of their code using a single tool with fast, consistent results.
As a Git-aware tool, Qlty CLI makes adopting linting into the development workflow easy by limiting results to only _new_ issues.
Qlty CLI is implemented in Rust, supported by [Qlty Software](https://qlty.sh), free to use, and is published under a [Fair Source](https://fair.io/) license.
## Features
- 🐞 Linting (for every programming language)
- 🖌️ Auto-formatting
- 🚨 Security scanning (IaC, SAST, SCA, and more)
- 📊 Complexity metrics and duplication
- 💩 Maintainability smells
## Installation
Qlty CLI is available for MacOS, Linux, and Windows.
### Install on MacOS or Linux
```bash
curl https://qlty.sh | bash
```
### Install on Windows
```bash
powershell -c "iwr https://qlty.sh | iex"
```
## Usage
Setup Qlty within a Git repository:
```bash
cd my_repo/
qlty init
```
View a sample of lint issues:
```bash
qlty check --sample=5
```
Auto-format the codebase:
```bash
qlty fmt --all
```
Scan for code smells like duplication:
```bash
qlty smells --all
```
Review a summary of code quality metrics:
```bash
qlty metrics --all --max-depth=2 --sort complexity --limit 10
```
## Plugins
Qlty CLI is powered by a set of 40+ plugins for static analysis tools like linters, auto-formatters, and security scanners. Plugin definitions can be found in the [`plugins/linters` directory](https://github.com/qltysh/qlty/tree/main/plugins/linters).
Creating a plugin can be as easy as writing a small plugin definition TOML file. If the tool has a custom output format (instead of a standard like [SARIF](https://sarifweb.azurewebsites.net/)), then writing a simple output parser in Rust is also needed.
We also happily accept requests for new plugins via [GitHub issues](https://github.com/qltysh/qlty/issues/new/choose).
## Configuration
Qlty CLI is configured using a `.qlty/qlty.toml` file in your Git repository. You can generate a default configuration with `qlty init` and then customize it.
Read our documentation about [configuration](https://docs.qlty.sh/analysis-configuration) for more information.
## Development
Developing on Qlty CLI requires a working [Rust toolchain](https://rustup.rs/).
```bash
cargo build
cargo test
```
