Scalaプログラミング入門

はじめに

Scala プログラミング入門用の Jupyter ノートブック (Almond Scala kernelを利用)を提供している． 以下のURLをクリックするとWebブラウザ上で実行できる!

自分用のBinderサイトの作り方

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

   cd scala-test
   git init
   git add .
   git commit -m "First commit"
   git remote add origin https://github.com/XXXXX/scala-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/scala-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 scala-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
