Wikifunctions consists of functions. A function can have a description in many languages with a list of parameters, test cases, a list of implementations in different programming languages, and further metadata, all in multiple languages (among those supported by Wikimedia). The implementations can be reused in other software projects (private apps or scripts), be called and executed online (simply in the browser, in a cloud environment, or in Jupyter[1] or PAWS[2] notebooks), composed to achieve more complex functionality, signed, analyzed, or validated, and much more.
Wikifunctions is a project in the spirit of Wikipedia, Wikidata, Wiktionary, and other similar global collaborative free culture projects: it allows contributors from all over the world to create and maintain a multilingual library of functions that can be used by anyone for any purpose. Every function can be supported by multiple implementations in different programming languages, test cases, pre- and post-conditions, documentation, metadata in the form of runtime estimates and complexity guarantees for the different implementations, etc. Users may call a function directly on the website, or from their own code or applications, from a command-line interface, or a local app. The function may be executed locally in the browser, in the cloud, or locally and embedded within the user's application.
Wikifunctions is intended to create both a well-defined common catalog of functions that can be widely reused and an environment where functions can be quickly combined and executed on the fly. Wikifunctions aims to make life easier for developers, who can rely on this repository like on any external library, and for end-users, who can call functions as needed, in a way that is currently only available with a very uneven coverage through specific websites that are often written in the form of 1990s websites with Java applets.
All functions are pure, in order to enable a secure sandboxed execution. Also, every implementation can be annotated with metadata and cryptographically signed. End-users can select and audit which implementation of each function to use, depending on their available hardware resources and web of trust settings.
Wikifunctions will allow easy access to large knowledge bases such as Wikidata, but also to binary input and output files. It is entirely possible to upload an image as an input file and return analysis results such as what is depicted on the image, or how many different colors the image has – or a different binary, e.g. in a different format. This will be made available to workflows on Wikimedia Commons.
Wikifunctions continues the tradition of moving more computation, which has usually happened on the command line or with apps by more computer-savvy users, to the Web and democratizing access to functionality that was not available before. At the same time, it will increase the productivity of developers everywhere, as they can just use a large library of code instead of relying on copying and pasting answers from sites like StackOverflow.
Unlike in Wikipedia, contributors will mostly create new implementations for a function instead of updating existing functions. The implementations can be automatically tested against the given tests, against each other, and further analyzed.
Implementations can be written in a number of different programming languages, but they will be able to call functions implemented in other programming languages. The execution engine can smoothly (although not necessarily with the highest possible performance) operate in different languages. Although in most cases there is a large performance boost in composing functions within a single programming language, there is no requirement to do so. In many cases, the speed of development and the developer's time will be more valuable than the additional computer cycles spent in the execution engine.
