Simple `format` directives to print in colors:

On [Ultralisp](https://ultralisp.org/).

~~~lisp
(format t "Hello ~/cyan/, are you a ~/green/ or ~/red/?" "you" "lisper" "not")
~~~

![](https://raw.githubusercontent.com/vindarel/format-colors/master/formatcolor.png)

Instead of (with `cl-ansi-text`):

~~~lisp
(use-package :cl-ansi-text)
(format t "Hello ~a, are you a ~a or ~a?" (cyan "you") (green "lisper") (red "not"))
;; or
;; (format t "Hello ~a, are you a ~a or ~a?" (cl-ansi-text:cyan "you") (cl-ansi-text:green "lisper") (cl-ansi-text:red "not"))
~~~

**Bold and italic modifiers**

Like all format directives, these can accept the `:` and `@` modifiers. `:` will be for `:`talic and `@` for b`@`ld.

"~:/blue/"
    "~@/blue/"

There are also numerical parameters that we don't use.

It is possible to call the color functions directly, their signature is `stream arg colon-p at-sign-p &rest params`:

~~~lisp
(blue t "hello" nil nil)
~~~

## Install

~~~lisp
(use-package :format-colors)
;; or import from :format-colors the symbols :red :blue :yellow :green :cyan :black :white :magenta.
~~~

That's all. Let's see how it goes.

ps: to enable colors in Slime, one solution is [M-x slime-repl-ansi-on](https://github.com/deadtrickster/slime-repl-ansi-color/) (in MELPA).

``` lisp
(with-eval-after-load 'slime-repl
  (require 'slime-repl-ansi-color))
(add-hook 'slime-repl-mode-hook 'slime-repl-ansi-color-mode)
```
