Examples using the Yauhau IO optimization

Blog

The blog example (blog.hs for the Haskell version and blog.clj for the (not currently runnable) clojure version) are adaptations of Simon Marlow's blog example he showed at ICFP14. The original source code for Marlow's version can be found here.

Our Haskell version is functionally identical, it only adds some simpleLift and call calls to run in ohua.

Running the Haskell example

  1. Install the Haskell build tool stack

    You can find instructions appropriate for your platform on the documentation web-site for stack.

  2. Clone the repository

    git clone https://github.com/ohua-dev/yauhau.git

  3. Build the project

    stack build --fast

    This command will download the necessary libraries and build the executable.

  4. Run the executable

    stack exec -- yauhau-blog-example

The actual compiled binary is found in <repo>/.stack-work/install/<platform>/<stack-snapshot>/<ghc-version>/bin/yauhau-blog-example. To obtain the concrete path for your system you can simply run stack exec -- which yauhau-blog-example after having compiled the project.

If you want to experiment with the example you can find the source in examples/blog.hs and this readme at examples/README.md.

Running the clojure example

The source for the clojure version of the blog example is found at examples/blog.clj.

Unfortunately due to a bug in the platform we use to bring ohua to the JVM this example does not currently run. Furthermore due to the bug we are unable to debug the example at the moment, its code is therefore most likely buggy to some extent.
