Using Binder

1. Add a Dockerfile to your Git repository (with the name Dockerfile) which uses the following template:

FROM rikedyp/dyalog-jupyter-binder:49 # This Docker container is a Dyalog Jupyter environment
COPY ./NotebookFolder/ ${HOME}        # NotebookFolder is a folder containing notebooks
ADD ./MyNotebook.ipynb ${HOME}        # MyNotebook.ipynb is an individual notebook

1. Go to mybinder.org and paste your repository URL
2. Click the launch button

Entering APL characters

You can get an APL language bar and enable key-bindings and character compositions using just a a bookmarklet (a browser bookmark that contains commands which add new features to the browser). After adding the bookmarklet to your language bar, and opening a Jupyter notebook document in your browser, click on the bookmarklet. You can insert APL characters in three ways:

1. Click on APL Keyboard. Click on an APL symbol, or on Shift, then an APL symbol.
2. Click on the Primer tab. Click on an APL symbol.
3. Type Backtick (`) and then the associated symbol (hover over symbols on Primer tab bar to see associations), e.g. Backtick+r makes ⍴ and Backtick+Shift+e makes ⍷.
