Have you ever written code that seems clear at first, but later leaves you scratching your head? Codiumate's /explain command is here to shed light on your code, providing clear explanations and usage examples directly within your VS Code editor's file mode.

Think of /explain as your personal code guide. It takes your selected code, analyzes it, and breaks it down into a clear and easy-to-understand explanation. No more hunting through documentation or deciphering cryptic comments. /explain gives you the straight scoop on what your code does.


Prompt: /explain [ optional additional information ]

What does it cover?

It takes the code you select and analyzes it thoroughly, generating a detailed explanation that covers various aspects, including:

  • Functionality: /explain clarifies what the code does, outlining its core purpose and the actions it performs.
  • Logic Flow: It disentangles the code's logic, explaining how different parts interact and the sequence of events that take place when the code is executed.
  • Variables and Data Types: /explain sheds light on the variables used within the code, their data types, and their roles in the overall functionality.
  • Control Flow (if/else, loops): Confusing conditional statements and loops become clear with /explain's breakdown of their logic and execution flow.
  • Function Calls: When your code interacts with other functions, /explain deciphers those calls, explaining their purpose and the data they exchange.

How to Use It:

Using /explain is as easy as:

  • Highlight your code: Select the specific lines of code you want explained (function, snippet, etc.).
  • Summon the explanation: Type /explain in your editor.

What to Expect:

/explain will break down your code into several sections:

  • Purpose: A concise explanation of what the code is designed to do.
  • Inputs: If the code takes any arguments (function parameters), /explain will list them here.
  • Flow Example: This section walks you through the code's step-by-step execution, explaining what happens at each stage.
  • Outputs: /explain will clarify what value or data the code returns.
  • Usage Example: To solidify your understanding, /explain might even provide a code example demonstrating how to use the explained code in practice.

Focus on Your Code

Here's where things get interesting! In File Mode, /explain offers different "Focus On" options in Code Block mode to tailor your questions:

  • Selected Lines: Focus on specific lines of code you have highlighted.
  • Complete File: Analyze the entire file for a broader understanding.
  • Specific Function: Target a particular function within the file for an in-depth explanation.

When is /explain Useful?

/explain is a valuable tool in various coding scenarios:

  • Understanding Legacy Code: Encountered someone else's code that's a mystery? /explain can translate it into plain English.
  • Debugging Complex Logic: Stuck on a tricky code block? /explain can help you unravel its flow and identify potential issues.
  • Learning New Concepts: Working with new code constructs? /explain can provide clear explanations and usage demonstrations.
  • Refreshing Your Memory: Revisited some code you wrote a while back? /explain can serve as a quick refresher.
