Welcome to the Extempore wiki

Extempore is a programming language and runtime environment designed with live programming in mind. It supports interactive programming in a REPL style, compiling code just-in-time. Although extempore has its roots in `live coding’ of audiovisual media art[fn:Impromptu], it is suitable for any task domain where dynamic run-time modifiability and good numerical performance are required. Extempore also has strong timing and concurrency semantics, which are helpful when working in problem spaces where timing is important (such as audio and video).

Extempore is currently under active development. The goals and ‘big picture’ of the project are probably best described here (blog post coming soon).

Getting started

The README.md has up-to-date instructions about installing and working with Extempore on the various platforms (Windows, OSX, Linux).

Getting help

If you run into troubles, there are lots of great examples (tutorials, really) in the examples/ subdirectory of the extempore source folder. If you get stuck, you can try the google group and mailing list. Other than that, we often hang out in channel #extempore on freenode, so feel free to drop by if you have any questions.
