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.[1] It was created in 2007 by Mike Mol.

As of 26 July 2018, Rosetta Code has:[2]

  • 882 programming tasks (or problems),
  • 223 additional draft programming tasks,
  • 676 programming languages,
  • 59,711 programming 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.[3]

The Rosetta Code web repository illustrates how desired functionality is implemented very differently in various programming paradigms,[4][5] and how "the same" task is accomplished in different programming languages.[6]

Data and structure[edit]

The Rosetta Code site is organized as a browsable 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 the C programming language will appear in the listing for C. If the same task has a solution in Ruby, the task will appear in the listing for Ruby as well.
