Some styles failed to load. 😵 Please try reloading this page. Markdown Extra is a lightweight markup language based on Markdown implemented in PHP (originally), Python and Ruby. It adds features not available with plain Markdown syntax. Markdown Extra is supported in some content management systems such as, for example, Drupal and TYPO3. Markdown Extra adds the following features to Markdown. In order to have a consistent output, I’m going to first convert my WordPress HTML into Markdown, and then generate each article from the Markdown, rather than converting it to straight up HTML, and then generating the Markdown. I found it was actually easier to go from WordPress HTML to Markdown, and then to normal HTML.
RDoc::Markdown as described by the markdownsyntax.
To choose Markdown as your only default formatsee Saved Options atRDoc::Options for instructions on setting up a.doc_options file to store your project default.
Markdown is a lightweight markup language for adding formatting elements to plain text. RubyMine recognizes Markdown files, provides a dedicated editor with highlighting, completion, and formatting, and shows the rendered HTML in a live preview pane. 这是一篇讲解如何正确使用 Markdown 的排版示例，学会这个很有必要，能让你的文章有更佳清晰的排版。 引用文本：Markdown is a text formatting syntax inspired. 这段内容展示了在内容里面一些小的格式，比如： 加粗 -.加粗. 倾斜 -.倾斜. 删除线.
Usage
Here is a brief example of using this parse to read a markdown file byhand.
Extensions
The following markdown extensions are supported by the parser, but not allare used in RDoc output by default.
RDoc
The RDocMarkdownparser has the following built-in behaviors that cannot be disabled.
Underscores embedded in words are never interpreted as emphasis. (While themarkdowndingus emphasizes in-word underscores, neither the Markdown syntax nor MarkdownTest mention thisbehavior.)
For HTML output, RDoc always auto-links bareURLs.
Break on Newline
The #break_on_newlineextension converts all newlines into hard line breaks as in Github FlavoredMarkdown. This extension is disabled by default.
CSS
The css extension enables CSSblocks to be included in the output, but they are not used for any built-inRDoc output format. This extension is disabledby default.
Example:
Definition Lists
The #definition_listsextension allows definition lists using the PHPMarkdown Extra syntax, but only one label and definition are supportedat this time. This extension is enabled by default.
Example:
Produces:
A small furry mammal that seems to sleep a lot
A little insect that is known to enjoy picnics
Strike
Example:
Produces:
This is ~~striked~~.
Github
The github extension enables apartial set of Github FlavoredMarkdown. This extension is enabled by default.
Supported github extensions include:
Ruby Markdown Free
Fenced code blocks
Use ``` around a block of code instead of indenting it fourspaces.
Syntax highlighting
Use ``` ruby as the start of a code fence to add syntaxhighlighting. (Currently only ruby syntax is supported).
HTML
Enables raw HTML to be included in the output. This extension is enabled bydefault.
Example:
Notes
The notes extension enablesfootnote support. This extension is enabled by default.
Example:
Produces:
Here is some text1including an inline footnote 2
Limitations
Link titles are not used
Footnotes are collapsed into a single paragraph

I recently spent some time automating the generation of Markdown tables-of-contents for compatibility with my open source projects in Github and also Gitlab Cloud. In the process, I reviewed a number of auto table-of-contents options by Markdown flavour and version, which I will document here.
Github Markdown
Github uses Github Flavoured Markdown (GFM), which is based on the CommonMark spec. GFM is documented here. As such, a table of contents is something you are expected to write yourself in Markdown, using inline links.
For example:
There are tools out there to auto-generate tables of contents e.g. markdown-toc, but I wanted something simpler and I wrote my own Ruby script to do it. My script is gen_markdown_toc.rb.
To use it (on a Mac):
Then copy the generated text in your Markdown file where you want the table of contents to appear.
Gitlab Markdown
As of now, Gitlab Cloud Markdown uses GFM as well, or at least the version of Gitlab Cloud that I tested this on does.
Note that Gitlab’s docs here reveal that until recently Gitlab used Kramdown under the hood (see below). I discovered this page here that explains why they migrated away from Kramdown and thereby broke the useful table of contents feature.
Bitbucket Markdown
According to documentation here, Bitbucket’s Markdown is also based on CommonMark, so I would expect my script to work on Bitbucket too.
Kramdown Markdown
Meanwhile, other versions of Markdown have built in features to auto-generate tables of contents. Kramdown documented here is a Ruby implementation of Markdown that makes tables of contents a lot easier. If you are using Kramdown, you just need to add this:
This Jekyll blog uses Kramdown Markdown for example.
RedCarpet Markdown
RedCarpet documented here is another flavour that makes auto-generation of tables of contents easy. It is apparently used in Gitlab’s Wikis. Just add this for a table of contents:
Typora Markdown
Another flavour is Typora Markdown documented here. For a ToC you can write:
Markdown Ruby Code
End note
Ruby Markdown Editor
These are all the Markdown formats I am aware of. I would like to keep this page up to date and to that end I welcome feedback and updates.
