# Elvis

I’m opening the main thread here for the Elvis-related libraries:

- [elvis\_core | Hex](https://hex.pm/packages/elvis_core) **-** The heart of all Elvis libraries, where all the rules are implemented.
- [elvis | Hex](https://hex.pm/packages/elvis) **-** The CLI that you can use to run Elvis in your projects if you don’t use **rebar3** or **erlang.mk**.
- [rebar3\_lint | Hex](https://hex.pm/packages/rebar3_lint) **-** The plugin that you can use to run Elvis in your rebar3-managed projects.
- [https://github.com/inaka/elvis.mk](https://elvis.mk) **-** The plugin that you can use to run Elvis in your elrang.mk-bound projects.

## What’s Elvis?

Elvis is an Erlang linter. You can find more about it in its repository: [GitHub - inaka/elvis\_core: The core of an Erlang linter](https://github.com/inaka/elvis_core)

Or watching this somewhat old video:

Fwiw, [katana\_code | Hex](https://hex.pm/packages/katana_code/2.4.1) (now 2.4.1) also got a release to fully support OTP 28.

Good stuff.

I might have spotted an issue in the documentation:

There is a rule named `No & `, the text of which which says:

> Use of `$ ` should be avoided.

The config option is:

> `{elvis_style, no_dollar_space, #{}}`

Thus it looks like it is the title that is incorrect.

You’re 100% correct. An bug report and/or a PR to fix this would be highly appreciated.

We’ve recently release a big new major version of Elvis, jumping into v5. This release introduces many new rules like robot butt (prefer `[_ | _] = list` over `0 < length(List)`), stricter consistent variable naming (`User_Id`, `UserID`, `Userid` all probably refer to the same entity and therefore could use a single name!), ABC size and cyclomatic complexity rules, and a few other niceties. It introduces a lot of performance improvements, and a more pleasant configuration.

- [Release 5.0.1 · inaka/elvis.mk · GitHub](https://github.com/inaka/elvis.mk/releases/tag/5.0.1)

Add it to your projects let Elvis rock your code!
