# syl20bnr contribution layer for Spacemacs

## Install

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

```elisp
(defvar dotspacemacs-configuration-layers '(syl20bnr)
  "List of contribution to load."
)
```

## Rainbow Identifiers

Instead of colorized keywords, this contribution has *colorized variables and
functions* using the [rainbow identifiers][rainbow-identifiers] mode. Each
variable and function has a unique color associated to it.

`rainbow-identifiers` mode can be toggled on and off with:

    <SPC> t c

The `saturation` and `lightness` of identifier colors can be adjusted with the
commands:

Key Binding   | Description
--------------|------------------------------------------------------------
`<SPC> c s`   | initiate change `saturation` mini-mode
`<SPC> c l`   | initiate change `lightness` mini-mode
`+`           | increase the `saturation` or `lightness`
`-`           | decrease the `saturation` or `lightness`
`=`           | reset the `saturation` or `lightness`
Any other key | leave the change mini-mode
