markdown-xblock 1.0.5

Markdown XBlock provides editing course content in Markdown.

Markdown XBlock

Based on the HTML XBlock by OpenCraft

Introduction

This XBlock allows course authors to create and edit course content in Markdown and displays it as HTML.

Installation

You may install the markdown-xblock using its setup.py, or if you prefer to use pip, run:

pip install markdown-xblock

If you prefer to install directly from Git, run:

pip install git+https://github.com/citynetwork/markdown-xblock.git

You may specify the -e flag if you intend to develop on the repo.

The minimum supported Python version is 3.5.

To enable this block, add "markdown" to the course's advanced module list. The option Markdown will appear in the advanced components.

Once you've added a new Markdown component to your course, you can also add custom CSS classes to the component by selecting EDIT/Settings and adding to the classes list (Note: use double quotes " "). Example:

["custom-css-class-1", "custom-css-class-2"]

The Markdown block uses markdown2 to translate the content into HTML, by default the following extras are included:

• "code-friendly"
• "fenced-code-blocks"
• "footnotes"
• "tables"
• "use-file-vars"

It is possible to configure more extras, by adding to the extras list under "markdown" key in XBLOCK_SETTINGS at /edx/etc/{studio|lms}.yml

By default, the safe_mode for markdown2 library is enabled, which means that writing inline HTML is not allowed and if written, all tags will be replaced with [HTML_REMOVED]. To disable this setting and allow inline HTML, you'll need to set the safe_mode to False in XBLOCK_SETTINGS.

Example:

XBLOCK_SETTINGS:
    markdown:
        extras:
            - code-friendly
            - fenced-code-blocks
            - footnotes
            - header-ids
            - metadata
            - pyshell
            - smarty-pants
            - strike
            - target-blank-links
            - use-file-vars
            - wiki-tables
            - tag-friendly
        safe_mode: True
