Anagrams solver with command line application

An anagram is a word or sentence that can be rearranged to create another one, such as parliament that can be turn into partial men, or Clint Eastwood can turn into Old West Action (Internet Anagram Server)

The initial goal is to implement a command line application that allows both finding the longest anagram and all existing ones at the loaded dictionary.

A dictionary is a list of lines in which each line contains only a word or a sentence.

The running application reads all the text files from the given directory, as a parameter, and gives us a prompt to search for anagrams as below:

$ groovy -cp ... <path-to-dictionary-folder>
Dictionary folder dict/words/en/ will be loaded
Use <ctrl> + C to finish
* Write a word for searching anagrams: ...

Environment

Running at the project root folder

The test will be running with

[project.path]$ ./gradlew test

Run the application executing

[project.path]$ groovy -cp libs/anagrams-solver-0.1.jar app/src/main/groovy/Anagrammatist <dictionaries folder path>

when 'anagrams' subproject jar was generated.

[project.path]$ ./gradlew anagrams:jar

Fun facts

"Anagrams" itself can be anagrammatized as "Ars magna" (Latin, 'the great art').

English language:

• Longest Words in the English Language
• A word can be composed by only vowels (a, e, i, o, u) as the word euouae
• I found the best anagram in English
