mudphone/everyelixirpatternmatchingexampleever

An example of every *type* of Elixir pattern matching.

Every example of pattern matching (almost) from the docs

Really, it's a lot of examples from the docs.

Plus some weird excursions, like Peano arithmetic (see Notebook 2), to illustrate pattern matching in recursion.

NOTE: This requires Python, Jupyter Notebooks, and IElixir for Jupyter.

Docker

From scratch (takes hours)

• docker build -t ielixir_notebook .
• Use the commands below to run a container.

From an image (large download)

• This assumes you have Docker installed.
• Pull the image docker pull mudphone/ielixir_notebook
• Clone this repo, then cd into it
• Run a container
  • docker run --name my_iex_notebook -it -p 8888:8888 --user jovyan -v "$PWD":/home/jovyan/jupyter-env/patterns mudphone/ielixir_notebook bash
• Note:
  • the name of the container: my_iex_notebook (make it what you wish)
  • the port: 8888 (you'll use this to connect to Jupyter notebooks)
  • the user: jovyan (that's the default Jupyter image user name)
  • the shared volume: -v host_source:container_target
• Start the container
  • docker start my_iex_notebook
• From the container, launch Jupyter notebook
• cd ~/jupyter-env
  • pipenv shell
  • jupyter notebook patterns
  • Note the URL, you'll use it to connect from the host
• From the host, connect to the notebook
  • Open a browser to http://127.0.0.1:8888/?token=xxxx
  • Note: token=xxxx must be replaced with whatever you saw from the container when you started the Jupyter notebook

Also

• Stop the container
  • docker stop my_iex_notebook
• Connect to a running container
  • docker exec -it --user jovyan my_iex_notebook bash
• Use --rm to rum a container and delete it after you exit
