Rosetta Code is a wiki-based programming chrestomathy website with implementations of common algorithms and solutions to various programming problems in many different programming languages. It was created in 2007 by Mike Mol.
As of 1 September 2015[update], Rosetta Code includes 775 programming tasks, and covers 569 programming languages with 45,546 language examples/entries. The site's content is licensed under the GNU Free Documentation License 1.2, though some components may be dual-licensed under more permissive terms.
The Rosetta Code web repository illustrates how desired functionality is implemented very differently in various programming paradigms., and how "the same" task is accomplished in different programming languages.
Data and structure
The Rosetta Code site is organized as a browseable cross-section of tasks (specific programming problems or considerations) and computer programming languages. A task's page displays visitor-contributed solutions in various computer languages, allowing a viewer to compare each language's approach to the task's stated problem. Task pages are included in per-language listings based on the languages of provided solutions; a task with a solution in C will appear in the listing for the computer language C. If the same task has a solution in Ruby, the task will appear in the listing for the Ruby computer language as well.
