From e3aa0d4f6d90bbf7fc5823aeb500ce7789a6eb87 Mon Sep 17 00:00:00 2001 From: Jacob Straszynski Date: Wed, 4 Feb 2026 17:03:18 -0800 Subject: [PATCH 1/3] Add support for partial nav inclusion using anchor syntax MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit adds the ability to include only specific sections of a navigation tree from an included mkdocs.yml file using anchor syntax. Syntax: !include path/to/mkdocs.yml#SectionName Changes: - Parse anchor fragments from include paths (e.g., #Guides) - Extract only the specified nav section from the included file - Generate unique aliases by appending section names to avoid conflicts - Update path resolution to handle anchored includes correctly Example usage: nav: - Guides: - My Section: "!include docs/other/mkdocs.yml#Guides" This allows for more flexible documentation organization by reusing specific sections of navigation trees without duplicating content or including entire documentation hierarchies. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- mkdocs_monorepo_plugin/parser.py | 44 ++++++++++++++++++++++++++++---- 1 file changed, 39 insertions(+), 5 deletions(-) diff --git a/mkdocs_monorepo_plugin/parser.py b/mkdocs_monorepo_plugin/parser.py index 1dbed44..b41d364 100644 --- a/mkdocs_monorepo_plugin/parser.py +++ b/mkdocs_monorepo_plugin/parser.py @@ -73,10 +73,12 @@ def getResolvedPaths(self): def extractAliasAndPath(absPath): loader = IncludeNavLoader(self.config, absPath).read() alias = loader.getAlias() + # Use the actual navPath (without anchor) for directory calculations + actualPath = loader.navPath docsDir = os.path.join( - loader.rootDir, os.path.dirname(absPath), loader.getDocsDir() + loader.rootDir, os.path.dirname(actualPath), loader.getDocsDir() ) - return [alias, docsDir, os.path.join(loader.rootDir, absPath)] + return [alias, docsDir, os.path.join(loader.rootDir, actualPath)] resolvedPaths = list( map(extractAliasAndPath, self.__loadAliasesAndResolvedPaths()) @@ -172,7 +174,12 @@ def __init__(self, config, navPath, ancestors=None): self.rootDir = os.path.normpath( os.path.join(os.getcwd(), config["config_file_path"], "../") ) - self.navPath = navPath + # Parse navPath for anchor (e.g., "path/to/mkdocs.yml#Guides") + if "#" in navPath: + self.navPath, self.navSection = navPath.split("#", 1) + else: + self.navPath = navPath + self.navSection = None self.absNavPath = os.path.normpath(os.path.join(self.rootDir, self.navPath)) self.navYaml = None # Track ancestor paths to detect cycles @@ -285,15 +292,42 @@ def getDocsDir(self): def getAlias(self): alias = self.navYaml["site_name"] + + # If a section is specified, append it to the alias to make it unique + if self.navSection: + alias = f"{alias}-{self.navSection}" + regex = "^[a-zA-Z0-9_\.\-/]+$" # noqa: W605 if re.match(regex, alias) is None: - alias = slugify(self.navYaml["site_name"]) + alias = slugify(alias) return alias def getNav(self): - return self._prependAliasToNavLinks(self.getAlias(), self.navYaml["nav"]) + nav = self.navYaml["nav"] + + # If a section is specified, extract only that section + if self.navSection: + nav = self._extractNavSection(nav, self.navSection) + if nav is None: + log.critical( + f"[mkdocs-monorepo] Could not find nav section '{self.navSection}' " + f"in {self.absNavPath}" + ) + raise SystemExit(1) + + return self._prependAliasToNavLinks(self.getAlias(), nav) + + def _extractNavSection(self, nav, section_name): + """Extract a specific section from the nav by its name.""" + for item in nav: + if isinstance(item, dict): + key = list(item.keys())[0] + if key == section_name: + # Return the contents of this section + return item[key] + return None def _prependAliasToNavLinks(self, alias, nav): for index, item in enumerate(nav): From 4206d62480e6de175823a59b73ed9b780168fa22 Mon Sep 17 00:00:00 2001 From: Jacob Straszynski Date: Thu, 5 Feb 2026 00:14:09 -0800 Subject: [PATCH 2/3] Add tests and documentation for anchor-based partial nav inclusion MIME-Version: 1.0 Content-Type: text/plain;
