Extempore

A programming environment for cyberphysical programming (Linux/macOS/Windows).

Note: Extempore is not yet compatible with Apple Silicon.

Getting started

The easy way

Download VSCode, install the Extempore extension and then use the Extempore: Download binary command to do the rest.

Note: Extempore's binary releases are built automatically for Windows, macOS and Linux (Linux release are built on Ubuntu, on other distros YMMV).

For more details, head to the Quickstart page in Extempore's online docs.

The slightly harder way (for those who don't want to use VSCode)

Download the latest binary release for your platform, unzip it and run extempore (extempore.exe on Windows) from inside the extempore folder.

Then, set up your text editor of choice and away you go.

Build from source

For more information, check out BUILDING.md.

Extempore's CMake build process downloads and build all the dependencies you need (including LLVM). So, if you've got a C++ compiler, git and CMake, here are some one-liner build commands:

On Linux/macOS:

git clone https://github.com/digego/extempore && mkdir extempore/build && cd extempore/build && cmake -DASSETS=ON .. && make && sudo make install

On Windows (if you're using VS2019---adjust as necessary for your VS version):

git clone https://github.com/digego/extempore && mkdir extempore/build && cd extempore/build && cmake -G "Visual Studio 16 2019" -A x64 -DASSETS=ON .. && cmake --build . --target INSTALL --config Release

Note: in the above one-liners the ASSETS build-time option (boolean, default OFF) is set to ON. This will download the Extempore binary assets---required for many of the examples, but adds a ~300MB download to build process. If you'd rather not do that, and are happy with some of the examples not working, then set -DASSETS=OFF instead.
