Macro Programming

Macro programming is a technique where developers write scripts or code snippets (macros) that automate repetitive tasks by expanding into larger sequences of instructions at compile-time or runtime. It is commonly used in applications like Microsoft Excel, text editors (e.g., Vim, Emacs), and programming languages (e.g., C/C++ preprocessor macros) to enhance productivity and reduce manual effort. Macros can range from simple keyboard shortcuts to complex automated workflows that manipulate data or control software behavior.

Also known as: Macros, Macro scripting, Automation scripting, Preprocessor macros, VBA macros

Why learn Macro Programming?

Developers should learn macro programming to automate tedious, repetitive tasks in their development environment, such as code generation, data transformation, or batch processing, which saves time and reduces errors. It is particularly useful in scenarios like spreadsheet automation in Excel, customizing text editors for efficient coding, or implementing compile-time code expansions in languages like C/C++ for performance optimization or code reuse. Mastering macros can significantly boost productivity in tool-heavy workflows.
