What is Hy?

Hy (a.k.a., Hylang) is a dialect of the Lisp programming language designed to interoperate with Python by translating expressions into Python's abstract syntax tree (AST). Similar to Clojure's mapping of s-expressions onto the JVM, Hy is meant to operate as a transparent Lisp front end to Python's abstract syntax. Hy also allows for Python libraries (including the standard library) to be imported and accessed alongside Hy code with a compilation step, converting the data structure of both into Python's AST.

How to use this image

Create a Dockerfile in your Hy project

FROM hylang:0.10
COPY . /usr/src/myapp
WORKDIR /usr/src/myapp
CMD [ "hy", "./your-daemon-or-script.hy" ]

You can then build and run the Docker image:

docker build -t my-hylang-app
docker run -it --rm --name my-running-app my-hylang-app

Run a single Hy script

For many simple, single file projects, you may find it inconvenient to write a complete Dockerfile. In such cases, you can run a Hy script by using the Hy Docker image directly:

docker run -it --rm --name my-running-script -v "$(pwd)":/usr/src/myapp -w /usr/src/myapp hylang:0.10 hy your-daemon-or-script.hy
