Understanding Currycombing in Software Development
Currycombing is a technique used in software development to break down a large function or method into smaller, more manageable pieces. It involves extracting a small piece of the original function and creating a new function that performs only that specific task. This new function can then be used as a building block to create larger functions or methods.
The term "curry" comes from the idea of taking a large dish (like a curry) and breaking it down into smaller, more digestible pieces. In software development, currycombing is a way of breaking down a complex function into smaller, more manageable pieces that can be easily understood and maintained.
Here's an example of how currycombing might work:
Suppose we have a large function called `do_accounting()` that performs a variety of accounting tasks, such as calculating taxes, generating invoices, and updating financial records. This function is too big and complex to be easily understood or maintained, so we decide to break it down into smaller pieces using currycombing.
First, we identify the different tasks that need to be performed within the `do_accounting()` function. These might include:
* Calculating taxes
* Generating invoices
* Updating financial records
Next, we extract each of these tasks into a separate function. For example, we might create functions called `calculate_taxes()`, `generate_invoices()`, and `update_financial_records()`. These new functions are much smaller and more focused than the original `do_accounting()` function, and they can be easily understood and maintained on their own.
Once we have these new functions, we can use them as building blocks to create larger functions or methods that perform more complex tasks. For example, we might create a function called `do_accounting_for_customer()` that uses the `calculate_taxes()`, `generate_invoices()`, and `update_financial_records()` functions to perform accounting tasks for a specific customer. This new function is still relatively large, but it is much easier to understand and maintain than the original `do_accounting()` function.
Overall, currycombing is a powerful technique for breaking down complex functions into smaller, more manageable pieces. It can help make code more modular, easier to understand, and easier to maintain.
