Yet another utilities for Common Lisp.

## System Requirements

One of the following Common Lisp implementations:

* [SBCL (Steel Bank Common Lisp)](http://www.sbcl.org/)

* [Clozure Common Lisp](https://ccl.clozure.com/)

* [CLISP](https://clisp.sourceforge.io/)

* [Embeddable Common Lisp](https://ecl.common-lisp.dev/)

* [ABCL (Armed Bear Common Lisp)](https://armedbear.common-lisp.dev/)

Among those implementations, SBCL is recommended for Lisp newcomers.

## Install

```shell

$ cd path/to/quicklisp/local-projects

$ git clone https://github.com/cwchentw/cl-yautils.git

```

## Usage

### Data Type

* `nullable`: declare a nullable data type ([ex](/examples/nullable-type.lisp))

### Variable

* `default`: set a default value for a variable with `nil` ([ex](/examples/default.lisp))

* `defined`: check whether a variable is defined ([ex](/examples/defined.lisp))

### Math

* `average`: get the average of numbers ([ex](/examples/average.lisp))

* `random-integer`: create a random integer ([ex](/examples/random-integer.lisp))

### List

* `proper-list`: convert a list with dotted pair(s) to a proper one ([ex](/examples/proper-list.lisp))

* `flatten`: flatten a list with or without dotted pair(s) ([ex](/examples/flatten.lisp))

### Console

* `puts`: print an object with a trailing newline to standard output ([ex](/examples/helloworld-cjk.lisp))

* `puterr`: print an object with a trailing newline to standard error ([ex](/examples/helloworld-cjk.lisp))
