プロジェクトの歴史

The IETF author resources describe document validation as an important step for Internet-Drafts and list idnits as the tool that validates plaintext I-Ds. The Author Tools web service also runs idnits behind the scenes alongside xml2rfc, kramdown-rfc, id2xml, and related tools.

The GitHub repository history is explicit about the transition: the project began as a snapshot mirror of idnits 2.17 from the older tools.ietf.org site, with idnits2 preserved on a v2 branch and idnits3 developed as a JavaScript-based CLI/library.

採用の歴史

idnits is adopted because IETF authors, working-group chairs, reviewers, and automated build systems need early feedback on draft boilerplate, formatting, references, and submission expectations. The Datatracker submission instructions recommend checking an Internet-Draft with idnits before submission.

The Node-based idnits3 packaging makes the tool easier to install in web services, CI jobs, and author workflows compared with the older shell-based generation.

使われ方

The idnits3 README documents installation through npm, npx use without installation, CLI modes such as normal and submission, output formats including pretty, simple, json, and count, and a library API based around checkNits().

Authors use idnits directly on RFCXML or plaintext drafts, or indirectly through the Author Tools service. Toolsmiths can use its library form to integrate draft checks into editors and publishing pipelines.

パッケージ好きにとっての重要性

idnits is package-nerd interesting because it encodes institutional publishing rules as a command-line tool. Its output can gate CI and submission preparation, so a package update can change what draft authors see as errors or warnings.

It also marks the IETF tooling migration from older tools.ietf.org-hosted scripts into maintained GitHub and npm-distributed components under the ietf-tools organization.
