The OctoPrint Plugin Repository is hosted on Github Pages. You can register new plugins by forking the source and just editing it accordingly:

  1. Fork the OctoPrint/ repository on Github to your own account.
  2. Clone the repository to your computer:

    git clone<your account>/
  3. Change into the just checked out folder

  4. Create a new file in the _plugins folder called <your plugin's identifier>.md following this template:

    layout: plugin
    id: your plugin's identifier
    title: your plugin's name
    description: short description of your plugin
    author: your name
    license: your plugin's license
    # today's date in format YYYY-MM-DD, e.g.
    date: 2015-06-22
    homepage: your plugin's homepage
    source: your plugin's source repository
    archive: archive link to install your plugin via pip
    # set this to true if your plugin uses the dependency_links setup parameter to include
    # library versions not yet published on PyPi. SHOULD ONLY BE USED IF THERE IS NO OTHER OPTION!
    follow_dependency_links: false
    - a list
    - of tags
    - that apply
    - to your plugin
    - (take a look at the existing plugins for what makes sense here)
    - url: url of a screenshot
      alt: alt-text of a screenshot
      caption: caption of a screenshot
    - url: url of another screenshot
      alt: alt-text of another screenshot
      caption: caption of another screenshot
    - ...
    featuredimage: url of a featured image for your plugin
      # list of compatible versions, for example 1.2.0. If left empty no specific version requirement will be assumed
      - 1.2.0
      # list of compatible operating systems, valid values are linux, windows, macos, leaving empty defaults to all
      - linux
      - windows
      - macos
    Longer description of your plugin, configuration examples etc. This part will be visible on the page at<your plugin identifier>/

    Note: If you used the OctoPrint cookiecutter template for your plugin as suggested in the Getting Started guide, it created a pre-filled file for you under extras/<your plugin's identifier>.md you just have to complete. Then copy it to _plugins/<your plugin's identifier>.

    If you are unsure how things should look take a look at the existing plugins.

    You may add screenshots to assets/img/plugins/<your plugin's identifier>/ (you’ll need to create this folder). You can then reference them as /assets/img/plugins/<your plugin's identifier>/your_image.png (the leading / here is important!).

    The image you define as featuredimage will be included in the plugin repository’s RSS feed and plugins.json file. Future versions of the plugin manager might also display it within OctoPrint.

    Important: Make sure your plugin's identifier is the same you will register your plugin under with OctoPrint! So if you entered my_awesome_plugin for plugin_identifier in cookiecutter make sure to use that exactly like that here too.

  5. Ideally, you’ll test that your plugin gets listed correctly and the plugin page looks as expected. For this you’ll need to install Jekyll, which is what Github Pages and hence the plugin repository uses for rendering the static repository from the source files. Make sure you have at least Ruby 2.0 installed.

    Github offers a nice setup guide that makes sure you have the exact versions of everything you need to run.

    Note: If you want to install Jekyll on Windows, you might want to give this step-by-step guide a look. You might run into some issues with the hitimes gem since at the time of writing this it hasn’t yet been adapted to the changes introduced in Ruby 2.2. If this is the case, take a look here.

    After installing Jekyll, a simple

    bundle exec jekyll serve

    will start up a server listening on localhost:4000 serving the whole page. Make sure your plugin shows up there under “Recently added” and the other listing types and that it page looks as you expected.

  6. Commit your changes:

    git add _plugins/<your plugin's identifier>.md
    git add assets/img/plugins/<your plugin's identifier>
    git commit

    Please use a meaningful commit message (e.g. “Added plugin <your plugin’s identifier”).

  7. Push your changes to your fork on Github:

    git push
  8. Create a pull request on Github against the original repository.
  9. Once your pull request is merged, your plugin will be listed. Congratulations!
