Include a file with anchor in mkdocs

This is a pluglet which defines a macro to include file contents using jinja2 template in mkdocs

In order for this to work, mkdocs macros plugin must be installed and defined.

I saw a really useful feature in mdbook here which essentially let you include a portion of the file into your web page.

A similar functionality is provided by this plugin. But it didn't seem to remove anchors tags when there are multiple of them defined in a file.

This pluglet bridges that gap.

This pluglet requires python 3.10. Support for other versions may be added.

pip install mkdocs-macros-plugin
pip install mkdocs-pluglet-file-include

update your mkdocs.yaml file with

plugins:
  - search
  - macros:
      modules:
        - mkdocs_pluglet_file_include

To include a portion of a file use

{{include_with_anchor('<file-name>', '<anchor name>'[, strip_prefix='<optional prefix>'])}}

File with sections defined (use the ANCHOR and ANCHOR_END keyword)

$ cat inc.txt
ANCHOR: begin
1. Item 1
2. Item 2
# ANCHOR: a
3. Item 3
4. Item 4
# ANCHOR_END: a
# ANCHOR_END: begin

File that includes contenets between anchors.

cat included.txt
Example: Include selected lines.
{{include_with_anchor('inc.txt', 'a')}}
Example: Include all lines.
{{include_with_anchor('inc.txt', 'begin')}}

After running mkdocs build, the resulting page would look like

Example: Include selected lines.
3. Item 3
4. Item 4
Example: Include all lines.
1. Item 1
2. Item 2
3. Item 3
4. Item 4
