## Install

### Layer

To use this contribution add it to your `~/.spacemacs`

```elisp
(setq-default dotspacemacs-configuration-layers '(clojure)
  "List of contribution to load."
)
```

### Pretty Symbols

Pretty symbols for anonymous functions and set literals, like `(λ [a] (+ a 5))`, `ƒ(+ % 5)`, and `∈{2 4 6}`.

To enable this feature, add the following snippet to the dotspacemacs/config
section of your `~/.spacemacs` file:

```elisp
(setq clojure-enable-fancify-symbols t)
```

Or set this variable when loading the configuration layer:
```elisp
(setq-default dotspacemacs-configuration-layers '(
  (clojure :variables
           clojure-enable-fancify-symbols t))
  "List of contribution to load."
)
```

### Cider

Cider requires nRepl middleware to function, please check the installation
instructions at the [cider repository][cider_install].
