Using Ruby or Bash in the iPython Notebook without having to run the magic command in each cell

Title: Streamlining Ruby and Bash in Jupyter Notebooks
Introduction:
Jupyter Notebooks are powerful tools for interactive computing, but by default, they are primarily designed for Python. However, with a little extra effort, you can seamlessly integrate other languages like Ruby and Bash into your Jupyter environment. In this tutorial, we'll explore how to use Ruby and Bash in Jupyter Notebooks without having to run magic commands in each cell.
Prerequisites:
Step 1: Installing the iruby Gem for Ruby:
Before using Ruby in Jupyter, you need to install the iruby gem. Open your terminal and run the following command:
This gem provides the necessary bridge between Ruby and the Jupyter environment.
Step 2: Configuring iruby:
Once the gem is installed, you need to configure it for Jupyter. Run the following command in your terminal:
This registers the Ruby kernel with Jupyter.
Step 3: Running Ruby in Jupyter Notebooks:
Now, you can open a Jupyter Notebook by running:
Create a new notebook and change the kernel to Ruby from the "Kernel" menu.
Example Ruby code in a Jupyter cell:
Step 4: Using Bash in Jupyter Notebooks:
To integrate Bash into Jupyter, we'll use the bash_kernel package. Install it using:
This installs and registers the Bash kernel with Jupyter.
Step 5: Running Bash in Jupyter Notebooks:
Open a new or existing Jupyter Notebook and select the Bash kernel for a cell.
Example Bash code in a Jupyter cell:
Step 6: Automating Cell Magic Commands:
To avoid running the magic command (%%ruby or %%bash) in each cell, you can use the cellmagics extension. Install it using:
After installation, you can use the "Cell Magics" toolbar to set the language for each cell.
Conclusion:
By following these steps, you can seamlessly integrate Ruby and Bash into your Jupyter Notebooks, making your interactive computing experience more versatile and efficient.
