THIS REPO IS NOT MAINTAINED

It will soon get deleted. I am currently working on a new and very much improved static site generator for Zettelkasten that works very well with Obsidian: mdzk. It is agnostic with regards to text editors, so it will work just as well with any other editor that supports wiki links. If you like Oboe, be sure to give mdzk a try.

Oboe

Installation - Usage - Tips

Oboe is a Python command line tool made to convert an Obsidian vault into a vault of HTML files, with the goal of publishing them as static files. It depends on the excellent markdown2 by trentm for Markdown parsing, but also deals with parsing Obsidian's flavor of Markdown. In addition, Oboe handles the structure of your vault and supports templates.

Installation

1. Make sure Python and PIP are installed.
2. Install Oboe with pip install git+https://github.com/kmaasrud/oboe

Usage

Supply the path to an Obsidian vault, and Oboe will convert all its notes into HTML, appended by the notes' backlinks.

oboe <path to vault>

These HTML-files are by default placed in the directory ./html. To specify another output directory, use the flag -o or --output-directory.

oboe <path to vault> -o <output directory>

Sub-directories

By default, Oboe only converts notes in the vault root, and not those inside sub-directories. To include sub-directories, add them with the flag -d or --sub-directories. For example, say you have the folders Daily notes and Zettels that you want to have converted. In this case, run

oboe <path to vault> -d "Daily notes" "Zettels"

If you want to include all sub-directories recursively and add every note in your vault regardless of where it is located, add the -d flag without any arguments.

Templates

The output is not very exciting from the get-go. It needs some style and structure. This is done by using a HTML template. A template must have the formatters {title} and {content} present. Their value should be obvious. The template file is supplied to obsidian-html by the flag -t or --template, like this:

oboe <path to vault> -t template.html

Here you can add metadata, link to CSS-files and add unified headers/footers to all the pages. Here's an example of how I use the template function on my own hosted vault.

Note that because of the way Python does formatting, the template cannot contain single curly braces other than the abovementioned formatters. To include Javascript or CSS in your template, always use double curly braces (e.g. {{). These will be changed into single braces in the final result.

Filtering notes by tag

Oboe supports only converting notes that contain a certain tag. The filter is specified via the -f or --filter flag. For example, say you had a tag #physics for notes relating to physics, and the same for #chemistry. To convert all notes relating to physics and/or chemistry, run Oboe like this:

oboe <path to vault> -f physics chemistry

Filters are not strict, so Oboe will convert any notes containing any of the tags in the filter. Filters can also be negated by prefixing a tag with ., for example:

oboe <path to vault> -f physics .chemistry

The above would convert all notes with the #physics tag, but exclude all notes with the #chemistry tag. If the filter contains only exclusions, Oboe will convert every note except those who match the exclusion.

Other flags

• -e or --add-file-extensions: Most web-servers do not need the .html file extension in URLs to find the correct file. However, that might be needed when browsing the converted vault locally. If you experience issues with this or want all links to have a .html extension, just add this flag when running.

• -bor --omit-backlink-dash: Removes the - in front of the backlink when inserted in html.

Tips

Publishing your vault automatically to GitHub Pages

Make a GitHub Actions workflow using the YAML below, and your vault will be published to GitHub Pages every time you push to the repository.

1. Make sure you have GitHub Pages set up in the vault, and that it has gh-pages /root as its source.

2. Copy and modify the following YAML job to match your repository. Add it to your vault repository as .github/workflows/publish.yml.

   name: Publish to GitHub Pages
   
   on:
     push:
       branches: [ master ]
   
   jobs:
     deploy:
       runs-on: ubuntu-latest
   
       steps:
       - uses: actions/checkout@v2
   
       - name: Set up Python 3.8
         uses: actions/setup-python@v2
         with:
           python-version: 3.8
   
     - name: Install oboe
       run: |
         python -m pip install --upgrade pip
         pip install git+https://github.com/kmaasrud/oboe.git
   
     - name: Generate HTML through oboe
       run: oboe ./vault -o ./out -t ./template.html -d daily
   
     - name: Publish
       uses: s0/git-publish-subdir-action@develop
       env:
         REPO: self
         BRANCH: gh-pages
         FOLDER: out
         GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

Support for TeX via KaTeX

By loading KaTeX in the HTML template and initializing it with $ and $$ as delimiters, you will have TeX support on the exported documents.

Just add this to the bottom of you template's body:

<!-- KaTeX -->
<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/[email protected]/dist/katex.min.css"
  integrity="sha384-zB1R0rpPzHqg7Kpt0Aljp8JPLqbXI3bhnPWROx27a9N0Ll6ZP/+DiW/UqRcLbRjq" crossorigin="anonymous">

<!-- The loading of KaTeX is deferred to speed up page rendering -->
<script defer src="https://cdn.jsdelivr.net/npm/[email protected]/dist/katex.min.js"
  integrity="sha384-y23I5Q6l+B6vatafAwxRu/0oK/79VlbSz7Q9aiSZUvyWYIYsd+qj+o24G5ZU2zJz"
  crossorigin="anonymous"></script>

<!-- To automatically render math in text elements, include the auto-render extension: -->
<script defer src="https://cdn.jsdelivr.net/npm/[email protected]/dist/contrib/auto-render.min.js"
  integrity="sha384-kWPLUVMOks5AQFrykwIup5lo0m3iMkkHrD0uJ4H5cjeGihAutqP0yW0J6dpFiVkI"
  crossorigin="anonymous"></script>

<!-- Parsing single dollar signs -->
<script>
  document.addEventListener("DOMContentLoaded", function () {{
      renderMathInElement(document.body, {{
        delimiters: [
          {{left: "$$", right: "$$", display: true}},
        {{left: "\\[", right: "\\]", display: true}},
    {{left: "$", right: "$", display: false}},
    {{left: "\\(", right: "\\)", display: false}}
      ]
  }});
  }});
</script>

Note the double {'s. This is to work around how Python formatting works, and will be correct in the outputted HTML.

Syntax highlighting

Using highlight.js, syntax highlighting is easily achieved.

Just add this to the bottom of you template's body:

<!-- Syntax highlighting through highlight.js -->
<link rel="stylesheet" href="https://unpkg.com/@highlightjs/[email protected]/styles/default.min.css">
<script src="https://unpkg.com/@highlightjs/[email protected]/highlight.min.js"></script>

<script>
  // Ignore highlighting of mermaid
  hljs.configure({{noHighlightRe: /^mermaid$/}});
  hljs.initHighlightingOnLoad();
</script>

Note the double {'s. This is to work around how Python formatting works, and will be correct in the outputted HTML.
