プロジェクトの歴史

The Hacker's Guide is dated September 1992, with revisions in August 1994 and December 1997. Ramsey's 1994 IEEE Software article 'Literate programming simplified' and the October 1997 Linux Journal article introduced the tool and its approach to a broader audience.

noweb's core idea is a pipeline. The Hacker's Guide describes how every tool begins with a noweb source file, transforms it through simple stages, and then emits code through notangle or documentation through noweave. That architecture let users add behavior by inserting pipeline stages rather than recompiling the tool.

The homepage notes that in 2018 Ramsey released version 2.12 and put noweb on GitHub. GitHub releases later list v2_12 in 2023 and v2_13 in 2023; Homebrew packages version 2.13.

採用の歴史

noweb's adoption was strongest in academic and research programming circles that valued literate programming across multiple languages. The homepage links a maintained user/project list, example programs, a postcard gallery online since April 1998, and LyX support since March 1999.

Homebrew's formula API reported only 49 install-on-request events in its 365-day analytics window. That does not erase the project's historical footprint; it shows that noweb is mostly legacy, archival, academic, or enthusiast infrastructure in modern macOS package usage.

使われ方

Users write source in noweb chunks, run notangle to extract compilable code, and run noweave to generate human-readable documentation. The tool intentionally avoids language-specific prettyprinting, trading that feature away for language independence and a small syntax.

Package nerds value noweb because it is old, portable, and inspectable. It ships a cluster of Unix-style tools such as notangle, noweave, noindex, noroots, nodefs, and noweb itself, making it a small literate-programming toolkit rather than a single renderer.

パッケージ好きにとっての重要性

noweb is a landmark in literate-programming tooling: less famous than WEB/CWEB, but influential because it made literate programming language-neutral and Unix-pipeline friendly. Its modern package presence is low, but its design remains a reference point for simple documentation/code extraction systems.
