About palindromes

A palindrome is a word, phrase, number, or other sequence of symbols or elements that reads the same forward or reversed, with general allowances for adjustments to punctuation and word dividers. Famous examples include "Amor, Roma", "A man, a plan, a canal: Panama" and "No 'x' in 'Nixon'".

Composing literature in palindromes is an example of constrained writing. The word "palindrome" was coined from the Greek roots palin (πάλιν; "again") and dromos (δρóμος; "way, direction") by the English writer Ben Jonson in the 17th century. The Greek phrase to describe the phenomenon is karkinikê epigrafê (καρκινικὴ επιγραφή; "crab inscription"), or simply karkinoi (καρκίνοι; "crabs"), alluding to the movement of crabs, such as an inscription that may be read backwards.

Installation

Install with Bower:

bower install --save palindromes

Testing

Install Node (comes with npm) and Bower.

From the repo root, install the project's development dependencies:

npm install
bower install

Testing relies on the Karma test-runner. If you'd like to use Karma to automatically watch and re-run the test file during development, it's easiest to globally install Karma and run it from the CLI.

npm install -g karma
karma start

To run the tests in Firefox, just once, as CI would:

npm test

To run the tests for your desired browser (any of Chrome, Firefox, Opera, IE):

karma start --browsers BrowserName --single-run
