From ad97f5573d6621d4861bfdcfbd433ca08e86a188 Mon Sep 17 00:00:00 2001 From: Johannes Kirschbauer Date: Thu, 2 Jul 2026 15:41:55 +0200 Subject: [PATCH] pkgs/nixos-render-docs: replace inlince tocs with collapsible sidebar tables of contents disconnect headings from body text. decouples heading levels from include type (part,chapter,part etc.) structure of the sidebar is derived from the include type for now. Can be changed to a meta file later. sidebar now uses proper ol-, li-, span-, a-tags definition tables are not ideal for navigation and accessibility breaking change: --toc-depth, --chunk-toc-depth, --section-toc-depth is now collapsed into --sidebar-depth --- doc/doc-support/package.nix | 3 +- doc/languages-frameworks/beam.section.md | 4 +- doc/style.css | 37 ++-- nixos/doc/manual/default.nix | 3 +- .../src/nixos_render_docs/html.py | 20 +-- .../src/nixos_render_docs/manual.py | 164 +++++++----------- .../src/tests/test_auto_id_prefix.py | 6 +- .../src/tests/test_manual.py | 116 +++++++++++++ .../src/tests/test_redirects.py | 2 +- 9 files changed, 210 insertions(+), 145 deletions(-) create mode 100644 pkgs/by-name/ni/nixos-render-docs/src/tests/test_manual.py diff --git a/doc/doc-support/package.nix b/doc/doc-support/package.nix index 3cc6daa32863..466beb204425 100644 --- a/doc/doc-support/package.nix +++ b/doc/doc-support/package.nix @@ -116,8 +116,7 @@ stdenvNoCC.mkDerivation ( --script ./highlightjs/loader.js \ --script ./anchor.min.js \ --script ./anchor-use.js \ - --toc-depth 1 \ - --section-toc-depth 1 \ + --sidebar-depth 3 \ manual.md \ out/index.html diff --git a/doc/languages-frameworks/beam.section.md b/doc/languages-frameworks/beam.section.md index 70ad1591be01..db4edaad4a4b 100644 --- a/doc/languages-frameworks/beam.section.md +++ b/doc/languages-frameworks/beam.section.md @@ -125,7 +125,7 @@ There are 2 ways to package backend dependencies: either per-dependency mix2nix When writing an elixir project targeting `mixRelease`, you can also consider using [deps_nix](https://github.com/code-supply/deps_nix) with `mixNixDeps`. `deps_nix` supports git dependencies, but is intended to be added to the project's `mix.exs` directly. -###### mix2nix {#mix2nix} +##### mix2nix {#mix2nix} `mix2nix` is a cli tool available in Nixpkgs.
