Copris Examples

Example Jupyter notebooks of Copris running on Almond Scala kernel.

You can run them on Binder.

How to create your own Binder site

Binder setup scripts are obtained from Almond Examples site.

1. Visit https://github.com/tamura70/copris-examples and download ZIP file
   • You will download copris-examples-master.zip file.
2. Unzip the downloaded file and rename the folder name as you like.
   • Say copris-test
3. Create your public repository on GitHub
   • Say https://github.com/XXXXX/copris-test (XXXXX is your ID)
4. Run some commands on your machine to update your GitHub repository

   cd copris-test
   git init
   git add .
   git commit -m "First commit"
   git remote add origin https://github.com/XXXXX/copris-test.git
   git push -u origin master
   

5. Create your Binder site
   • Access Binder with Firefox or Chrome
   • Enter your GitHub repository name (say, XXXXX/copris-test)
   • Copy the URL to access your Binder site later
   • Click "launch" button
   • Wait for a while. Your browser will be redirected after the docker image is created.
6. Modify/create Jupyter notebooks as you like in your browser!
7. Download your notebooks into copris-test directory
   • Otherwise, your work will disappear in vain!
8. Reflect your changes to the repositry

   git add .
   git commit -m "Modify notebooks"
   git push
   

9. Access your Binder site again
   • The docker image will be recreated automatically (this will also take a time)
   • Appending ?urlpath=lab to the URL gives a better GUI

Org-mode

Jupyter notebook files (.ipynb) are exported from Org-mode files by ox-ipynb macro in scimax package. The following is my scimax setting in user/user.el.

(add-to-list 'load-path "~/lib/scimax/ox-ipynb")
(require 'ob-scala)
(require 'ox-ipynb)
(add-to-list 'ox-ipynb-kernelspecs
	     '(scala . (kernelspec . ((display_name . "Scala")
				      (language . "scala")
				      (name . "scala")))))
(add-to-list 'ox-ipynb-language-infos
	     '(scala  . (language_info . ((codemirror_mode . "text/x-scala")
					  (file_extension . ".scala")
					  (mimetype . "text/x-scala")
					  (name . "scala")
					  (nbconvert_exporter . "script")
					  (version . "2.12.8")))))
