Getting auto appending snippets working with mkdocs

Question

Just discovered mkdocs and really like it. I am currently porting online done in a proprietary tool into it.

The only stumbling block I've had is implementing auto-appending snippets.

I was able to implement abbreviations as described here:

https://squidfunk.github.io/mkdocs-material/reference/abbreviations/

My next step was to add a glossary as described on that page by moving those abbreviations into a snippets file as described on the same page.

But rather than having to manually add the snippets to every Markdown file in my project, I wanted to use auto-append as described here:

https://facelessuser.github.io/pymdown-extensions/extensions/snippets/

My mkdocs.yml file declares its theme and extensions as follows:

theme:
    name: material 
markdown_extensions:
  - attr_list
  - abbr
  - pymdownx.snippets

But, I'm unclear on where I exactly configure "auto_append", "base_path" and the other options mentioned in that latter document. If anyone has a working example I'd appreciate it.

EDIT 18 Jan 2023: I can now get the auto_append working using the following configuration in mkdocs.yml:

theme:
    name: material 
markdown_extensions:
  - pymdownx.snippets:
      auto_append: ["abbreviations.md"]
      # base_path: ["."]  
      base_path: ["docs"]

...where my file structure is as follows:

[docs]
  abbreviations.md
  {other topics.md}
[includes]
[site]
mkdocs.yml

However, as soon as I add - attr_list and - abbr to mkdocs.yml, auto append stops working:

theme:
    name: material 
markdown_extensions:
  - attr_list
  - abbr
  - pymdownx.snippets
      auto_append: ["abbreviations.md"]
      # base_path: ["."]  # for root of repo
      base_path: ["docs"]

Answer 1

The snippet options are provided where you specify the markdown_extensions in your mkdocs.yml file, e.g.

# mkdocs.yml
...

markdown_extensions:
  - pymdownx.snippets:
      auto_append: ["../LICENSE"]
      # base_path: ["."]  # for root of repo
      base_path: ["docs"]

Hopefully this helps!
