What is the history of incremental compilation?

Incremental compilation is a technique that allows a compiler to compile only the parts of a program that have changed. It dates back to the 1970s, with early implementations in languages like Lisp. Over the years, it has evolved significantly, improving build times and efficiency in software development.

What were some key milestones in its development?

Key milestones include the introduction of incremental compilers in the 1980s, the development of tools like Make and later Gradle, and advancements in IDEs that support real-time feedback and compilation.

How does it compare to full compilation?

Incremental compilation is generally faster than full compilation because it only recompiles modified code, while full compilation processes the entire codebase, which can be time-consuming.

What are the benefits of using incremental compilation?

The main benefits include reduced build times, improved developer productivity, and quicker feedback loops, which are essential in modern agile development environments.

Are there any downsides to incremental compilation?

Yes, potential downsides include increased complexity in the build system and the possibility of stale dependencies if not managed properly.
