- Literate programming, as introduced by Donald Knuth, focuses on combining top-down exposition with flexible programming approaches.
- Knuth's literate programming was influenced by structured programming and aims to decompose code into understandable chunks without rigid subroutine structures.
- Examples of literate programming include Knuth's TeX and Metafont, David R. Hanson's C Interfaces and Implementations, and Bob Nystrom's Crafting Interpreters.
- Literate programming is particularly useful for preserving knowledge tied to a program, such as algorithms or specific programming practices.
- Challenges of literate programming include balancing pedagogy with programming, handling revisions, and the lack of modern tooling.
- Strategies for writing literate programs vary, including writing code first (Nystrom), writing prose first (Sewell), or a hybrid approach.
- Organizing content in literate programming requires careful consideration of readability and logical flow, often using hierarchical chunking.
- The choice of programming language impacts the style and presentation of literate programming, with different tools available for different languages.
- Successful literate programming requires iterative rewriting of both code and prose to ensure clarity and accuracy.
- Despite its challenges, literate programming remains a valuable tool for documenting and preserving complex programming knowledge.
