Anagram finder
==============

[](#anagram-finder)

This tool is the result of an exercise (code kata, coding dojo) for test-driven development (TDD) for PHP using PHPUnit at Oliver Klee's workshops.

An anagram is pair of two words that consist of exactly the same letters, but in different order.

Example: anthologise, theologians

The dictionaries have been copied from the [most-common-words-by-language](https://github.com/oprogramador/most-common-words-by-language)project.

Installation
------------

[](#installation)

Run `composer install` to install the required Composer packages.

How to run it
-------------

[](#how-to-run-it)

```
bin/find-anagrams
```

You can also specify a dictionary to use from `resources/dictionaries/`:

```
bin/find-anagrams german.txt
```

The exercises
-------------

[](#the-exercises)

The big picture is this: "Find and output all anagrams from a text file with a list of words."

1. Create a class that reads a list of words from a file and returns it as an array.
2. Create a class that takes a word and sorts the characters.
3. Create a class that finds and returns the anagram from an array of words.
4. Deal with duplicates and empty lines in the file gracefully.
5. Find the anagrams in a case-insensitive way.
6. Sort the anagrams alphabetically during output.
