I think generic preprocessor support would be awesome, there are a few I am interested in personally:

• mdbook-admonish
• mdbook-mermaid
• mdbook-toc
• mdbook-linkcheck

[peaceiris]

Other preprocessors except mdbook-admonish have pre-built binaries, so it looks possible to implement them.

Preprocessor name	Binary assets
mdbook-admonish	No
mdbook-mermaid	Yes
mdbook-toc	Yes
mdbook-linkcheck	Yes

[bgianfo]

Just as an FYI, mdbook-admonish now produces pre-built binaries.

I'd like to see mdbook-template as well 😄

I found mdbook-kroki-preprocessor, another excellent preprocessor which provides a unified API with support for many well-known textual graphs. Hope also give a support of.

and mdbook-katex

I propose editing the title of this issue to be about Preprocessors in general.

I'd like to add the mdbook-d2 plugin for consideration.

I found this issue wanting support for mdbook-quiz 🙏.

I actually use mdbook-graphviz, do you know a way to install it via the GitHub workflow.yml?

[SeniorMars]

This is the workflow I use. I don't like it but it works:

name: GitHub Pages
on:
  push:
    branches:
      - main
  pull_request:

concurrency:
  group: ${{ github.workflow }}-${{ github.ref }}
  cancel-in-progress: false

permissions:
  contents: write  # To push a branch
  pages: write  # To push to a GitHub Pages site
  id-token: write # To update the deployment status

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
        with:
          fetch-depth: 0

      - name: Install cargo
        uses: actions-rs/toolchain@v1
        with:

          profile: minimal
      # Cache installation assets
      - name: Cache cargo registry
        uses: actions/cache@v1
        with:

          key: ${{ runner.os }}-cargo-registry-${{ hashFiles('**/Cargo.lock') }}
      - name: Cache cargo index

      - name: Install mdbook and admonis plugin
        uses: actions-rs/cargo@v1
        with:

      - name: Build Book
        run: |
          mdbook-admonish install ./
          mdbook build
          touch ./book/.nojekyll
          touch ./book/CNAME
          echo 'lazy.rice.edu' >> book/CNAME
      - name: Upload artifact
        uses: actions/upload-pages-artifact@v3
        with:
          # Upload entire repository
          path: 'book'
  deploy:
    environment:
      name: github-pages
      url: ${{ steps.deployment.outputs.page_url }}
    runs-on: ubuntu-latest
    needs: build
    steps:
      - name: Deploy to GitHub Pages
        id: deployment
        uses: actions/deploy-pages@v4```

I also maintain the docker image for mdBook including the following preprocessor. It seems to be useful for some of you who are using those preprocessors.

• mdbook-mermaid
• mdbook-toc
• mdbook-admonish

[SeniorMars]

This is useful, but it would be nice to have it within actions if possible.
