### Quick start in example

[](#quick-start-in-example)

Let's imagine we want to write a simple calculator and we need a lexer (lexical analyzer) that provides a stream of IDs, numbers and operators. Create a new Composer project and execute following command from project directory:

```
composer require --dev remorhaz/php-unilex

Next step is creating a lexer specification in `LexerSpec.php` file. We use `@lexToken` tag in comments to specify regular expression for a token:

```
