Backwards-incompatible changes¶

enable_attributes keyword deprecated¶

The enable_attributes keyword is deprecated in version 3.0 and will beignored. Previously the keyword was True by default and enabled anundocumented way to define attributes on document elements. The feature has beenremoved from version 3.0. As most users did not use the undocumented feature, itshould not affect most users. For the few who did use the feature, it can beenabled by using the Legacy Attributesextension.

smart_emphasis keyword and smart_strong extension deprecated¶

The smart_emphasis keyword is deprecated in version 3.0 and will be ignored.Previously the keyword was True by default and caused the parser to ignoremiddle-word emphasis. Additionally, the optional smart_strong extensionprovided the same behavior for strong emphasis. Both of those features are nowpart of the default behavior, and the LegacyEmphasis extension is available to disable thatbehavior.

output_formats simplified to html and xhtml.¶

The output_formats keyword now only accepts two options: html and xhtmlNote that if (x)html1, (x)html4 or (x)html5 are passed in, the number isstripped and ignored.

safe_mode and html_replacement_text keywords deprecated¶

Both safe_mode and the associated html_replacement_text keywords aredeprecated in version 3.0 and will be ignored. The so-called 'safe mode' wasnever actually 'safe' which has resulted in many people having a false sense ofsecurity when using it. As an alternative, the developers of Python-Markdownrecommend that any untrusted content be passed through an HTML sanitizer (likeBleach) after being converted to HTML by markdown. In fact, Bleach Whitelistprovides a curated list of tags, attributes, and styles suitable for filteringuser-provided HTML using bleach.

If your code previously looked like this:

Then it is recommended that you change your code to read something like this:

If you are not interested in sanitizing untrusted text, but simply desire toescape raw HTML, then that can be accomplished through an extension whichremoves HTML parsing:

As the HTML would not be parsed with the above Extension, then the serializerwill escape the raw HTML, which is exactly what happened in previous versionswith safe_mode='escape'.

Positional arguments deprecated¶

Positional arguments on the markdown.Markdown() class are deprecated as areall except the text argument on the markdown.markdown() wrapper function.Using positional arguments will raise an error. Only keyword arguments should beused. For example, if your code previously looked like this: Macbooster 4 1 2 download free.

Then it is recommended that you change it to read something like this:

Note

This change is being made as a result of deprecating 'safe_mode' as thesafe_mode argument was one of the positional arguments. When that argumentis removed, the two arguments following it will no longer be at the correctposition. It is recommended that you always use keywords when they aresupported for this reason.

Extension name behavior has changed¶

In previous versions of Python-Markdown, the built-in extensions receivedspecial status and did not require the full path to be provided. Additionally,third party extensions whose name started with 'mdx_' received the samespecial treatment. This is no longer the case.

Support has been added for extensions to define an entrypoint. An entry point is a string name whichcan be used to point to an Extension class. The built-in extensions now haveentry points which match the old short names. And any third-party extensionswhich define entry points can now get the same behavior. See the documentationfor each specific extension to find the assigned name.

If an extension does not define an entry point, then the full path to theextension must be used. See the documentation fora full explanation of the current behavior.

Extension configuration as part of extension name deprecated¶

The previously documented method of appending the extension configurationoptions as a string to the extension name is deprecated and will raise an error.The extension_configs keyword should beused instead. See the documentation for afull explanation of the current behavior.

HeaderId extension deprecated¶

The HeaderId Extension is deprecated and will raise an error if specified. Usethe Table of Contents Extension instead, which offersmost of the features of the HeaderId Extension and more (support for meta datais missing).

Extension authors who have been using the slugify and unique functionsdefined in the HeaderId Extension should note that those functions are nowdefined in the Table of Contents extension and should adjust their importstatements accordingly (from markdown.extensions.toc import slugify, unique).

Homegrown OrderedDict has been replaced with a purpose-built Registry¶

All processors and patterns now get 'registered' to aRegistry. A backwards compatible shim isincluded so that existing simple extensions should continue to work.A DeprecationWarning will be raised for any code which calls the old API.

Markdown class instance references.¶

Previously, instances of the Markdown class were represented as any one ofmd, md_instance, or markdown. This inconsistency made it difficult whendeveloping extensions, or just maintaining the existing code. Now, all instancesare consistently represented as md.

The old attributes on class instances still exist, but raise aDeprecationWarning when accessed. Also on classes where the instance wasoptional, the attribute always exists now and is simply None if no instancewas provided (previously the attribute would not exist).

markdown.util.isBlockLevel deprecated¶

The markdown.util.isBlockLevel function is deprecated and will raise aDeprecationWarning. Instead, extensions should use the isBlockLevel methodof the Markdown class instance. Additionally, a list of block level elementsis defined in the block_level_elements attribute of the Markdown class whichextensions can access to alter the list of elements which are treated as blocklevel elements.

md_globals keyword deprecated from extension API¶

Previously, the extendMarkdown method of a markdown.extensions.Extensionsubclasses accepted an md_globals keyword, which contained the value returnedby Python's globals() built-in function. As all of the configuration is nowheld within the Markdown class instance, access to the globals is no longernecessary and any extensions which expect the keyword will raise aDeprecationWarning. A future release will raise an error.

markdown.version and markdown.version_info deprecated¶

Historically, version numbers were acquired via the attributesmarkdown.version and markdown.version_info. Moving forward, a morestandardized approach is being followed and versions are acquired via themarkdown.__version__ and markdown.__version_info__ attributes. The legacyattributes are still available to allow distinguishing versions between thelegacy Markdown 2.0 series and the Markdown 3.0 series, but in the future thelegacy attributes will be removed.

Added new, more flexible InlineProcessor class¶

A new InlineProcessor class handles inline processing much better and allowsfor more flexibility. The new InlineProcessor classes no longer utilizeunnecessary pretext and post-text captures. New class can accept the buffer thatis being worked on and manually process the text without regular expressions andreturn new replacement bounds. This helps us to handle links in a better way andhandle nested brackets and logic that is too much for regular expression.

New features¶

The following new features have been included in the release:

• A new testing framework is included as a part of the Markdown library, which can also be used by third party extensions.

• A new toc_depth parameter has been added to the Table of Contents Extension.

• A new toc_tokens attribute has been added to the Markdown class by the Table of Contents Extension, which contains the raw tokens used to build the Table of Contents. Users can use this to build their own custom Table of Contents rather than needing to parse the HTML available on the toc attribute of the Markdown class.

• When the Table of Contents Extension is used in conjunction with the Attribute Lists Extension and a data-toc-label attribute is defined on a header, the content of the data-toc-label attribute is now used as the content of the Table of Contents item for that header.

• Additional CSS class names can be appended to Admonitions.

Overview

Nearly all Markdown applications support the basic syntax outlined in John Gruber's original design document. Free chat clients for windows. There are minor variations and discrepancies between Markdown processors — those are noted inline wherever possible.

Headings

To create a heading, add number signs (#) in front of a word or phrase. The number of number signs you use should correspond to the heading level. For example, to create a heading level three (

), use three number signs (e.g., ### My Header).

Markdown	HTML	Rendered Output
# Heading level 1	Heading level 1
## Heading level 2	Heading level 2	Heading level 2
### Heading level 3	Heading level 3	Heading level 3
#### Heading level 4	Heading level 4	Heading level 4
##### Heading level 5	Heading level 5	Heading level 5
###### Heading level 6	Heading level 6	Heading level 6

Alternate Syntax

Alternatively, on the line below the text, add any number of characters for heading level 1 or -- characters for heading level 2.

Heading Best Practices

Markdown applications don't agree on how to handle a missing space between the number signs (#) and the heading name. For compatibility, always put a space between the number signs and the heading name.

Paragraphs

To create paragraphs, use a blank line to separate one or more lines of text.

Paragraph Best Practices

Unless the paragraph is in a list, don't indent paragraphs with spaces or tabs.

Line Breaks

To create a line break (
), end a line with two or more spaces, and then type return.

Line Break Best Practices

You can use two or more spaces (commonly referred to as 'trailing whitespace') for line breaks in nearly every Markdown application, but it's controversial. It's hard to see trailing whitespace in an editor, and many people accidentally or intentionally put two spaces after every sentence. For this reason, you may want to use something other than trailing whitespace for line breaks. Fortunately, there is another option supported by nearly every Markdown application: the
HTML tag.

For compatibility, use trailing white space or the
HTML tag at the end of the line.

There are two other options I don't recommend using. CommonMark and a few other lightweight markup languages let you type a backslash () at the end of the line, but not all Markdown applications support this, so it isn't a great option from a compatibility perspective. And at least a couple lightweight markup languages don't require anything at the end of the line — just type return and they'll create a line break.

Emphasis

You can add emphasis by making text bold or italic.

Bold

To bold text, add two asterisks or underscores before and after a word or phrase. To bold the middle of a word for emphasis, add two asterisks without spaces around the letters.

Bold Best Practices

Markdown applications don't agree on how to handle underscores in the middle of a word. For compatibility, use asterisks to bold the middle of a word for emphasis.

Italic

To italicize text, add one asterisk or underscore before and after a word or phrase. To italicize the middle of a word for emphasis, add one asterisk without spaces around the letters.

Italic Best Practices

Markdown applications don't agree on how to handle underscores in the middle of a word. For compatibility, use asterisks to italicize the middle of a word for emphasis.

Bold and Italic

To emphasize text with bold and italics at the same time, add three asterisks or underscores before and after a word or phrase. To bold and italicize the middle of a word for emphasis, add three asterisks without spaces around the letters.

Bold and Italic Best Practices

Markdown applications don't agree on how to handle underscores in the middle of a word. For compatibility, use asterisks to bold and italicize the middle of a word for emphasis.

Blockquotes

To create a blockquote, add a > in front of a paragraph.

The rendered output looks like this:

Izotope rx 7 audio editor advanced 7 01 pc. Dorothy followed her through many of the beautiful rooms in her castle.

Blockquotes with Multiple Paragraphs

Blockquotes can contain multiple paragraphs. Add a > on the blank lines between the paragraphs.

The rendered output looks like this:

Dorothy followed her through many of the beautiful rooms in her castle.

The Witch bade her clean the pots and kettles and sweep the floor and keep the fire fed with wood.

Nested Blockquotes

Blockquotes can be nested. Crack plugin alliance. Add a >> in front of the paragraph you want to nest.

The rendered output looks like this:

Dorothy followed her through many of the beautiful rooms in her castle.

The Witch bade her clean the pots and kettles and sweep the floor and keep the fire fed with wood.

Blockquotes with Other Elements

Blockquotes can contain other Markdown formatted elements. Not all elements can be used — you'll need to experiment to see which ones work.

The rendered output looks like this:

The quarterly results look great!

• Revenue was off the chart.
• Profits were higher than ever.

Everything is going according to plan.

Lists

You can organize items into ordered and unordered lists.

Ordered Lists

To create an ordered list, add line items with numbers followed by periods. The numbers don't have to be in numerical order, but the list should start with the number one.

Ordered List Best Practices

CommonMark and a few other lightweight markup languages let you use a parenthesis ()) as a delimiter (e.g., 1) First item), but not all Markdown applications support this, so it isn't a great option from a compatibility perspective. For compatibility, use periods only.

Unordered Lists

To create an unordered list, add dashes (-), asterisks (*), or plus signs (+) in front of line items. Indent one or more items to create a nested list.

Unordered List Best Practices

Markdown applications don't agree on how to handle different delimiters in the same list. For compatibility, don't mix and match delimiters in the same list — pick one and stick with it.

Adding Elements in Lists

To add another element in a list while preserving the continuity of the list, indent the element four spaces or one tab, as shown in the following examples.

Paragraphs

The rendered output looks like this:

• This is the first list item.

• Here's the second list item.

  I need to add another paragraph below the second list item.

• And here's the third list item.

Blockquotes

The rendered output looks like this:

• This is the first list item.

• Here's the second list item.

  A blockquote would look great below the second list item.

• And here's the third list item.

Code Blocks

Code blocks are normally indented four spaces or one tab. When they're in a list, indent them eight spaces or two tabs.

The rendered output looks like this:

1. Open the file.

2. Find the following code block on line 21:

3. Update the title to match the name of your website.

Images

The rendered output looks like this:

1. Open the file containing the Linux mascot.

2. Marvel at its beauty.

3. Close the file.

Lists

You can nest an unordered list in an ordered list, or vice versa.

The rendered output looks like this:

1. First item
2. Second item
3. Third item
   • Indented item
   • Indented item
4. Fourth item

Code

To denote a word or phrase as code, enclose it in backticks (`).

Escaping Backticks

If the word or phrase you want to denote as code includes one or more backticks, you can escape it by enclosing the word or phrase in double backticks (``).

Code Blocks

To create code blocks, indent every line of the block by at least four spaces or one tab.

The rendered output looks like this:

Horizontal Rules

To create a horizontal rule, use three or more asterisks (***), dashes (---), or underscores (___) on a line by themselves.

The rendered output of all three looks identical:

Horizontal Rule Best Practices

For compatibility, put blank lines before and after horizontal rules.

Escaping Backticks

If the word or phrase you want to denote as code includes one or more backticks, you can escape it by enclosing the word or phrase in double backticks (``).

Code Blocks

To create code blocks, indent every line of the block by at least four spaces or one tab.

The rendered output looks like this:

Horizontal Rules

To create a horizontal rule, use three or more asterisks (***), dashes (---), or underscores (___) on a line by themselves.

The rendered output of all three looks identical:

Horizontal Rule Best Practices

For compatibility, put blank lines before and after horizontal rules.

Links

To create a link, enclose the link text in brackets (e.g., [Duck Duck Go]) and then follow it immediately with the URL in parentheses (e.g., (https://duckduckgo.com)).

The rendered output looks like this:

My favorite search engine is Duck Duck Go.

Adding Titles

You can optionally add a title for a link. This will appear as a tooltip when the user hovers over the link. To add a title, enclose it in parentheses after the URL.

The rendered output looks like this:

My favorite search engine is Duck Duck Go.

URLs and Email Addresses

To quickly turn a URL or email address into a link, enclose it in angle brackets.

The rendered output looks like this:

https://www.markdownguide.org
fake@example.com

Formatting Links

To emphasize links, add asterisks before and after the brackets and parentheses. To denote links as code, add backticks in the brackets.

The rendered output looks like this:

I love supporting the EFF.
This is the Markdown Guide.
See the section on code.

Reference-style Links

Reference-style links are a special kind of link that make URLs easier to display and read in Markdown. Reference-style links are constructed in two parts: the part you keep inline with your text and the part you store somewhere else in the file to keep the text easy to read.

Formatting the First Part of the Link

The first part of a reference-style link is formatted with two sets of brackets. The first set of brackets surrounds the text that should appear linked. The second set of brackets displays a label used to point to the link you're storing elsewhere in your document.

Although not required, you can include a space between the first and second set of brackets. The label in the second set of brackets is not case sensitive and can include letters, numbers, spaces, or punctuation.

This means the following example formats are roughly equivalent for the first part of the link:

• [hobbit-hole][1]
• [hobbit-hole] [1]

Formatting the Second Part of the Link

The second part of a reference-style link is formatted with the following attributes:

1. The label, in brackets, followed immediately by a colon and at least one space (e.g., [label]: ).
2. The URL for the link, which you can optionally enclose in angle brackets.
3. The optional title for the link, which you can enclose in double quotes, single quotes, or parentheses.

This means the following example formats are all roughly equivalent for the second part of the link:

• [1]: https://en.wikipedia.org/wiki/Hobbit#Lifestyle
• [1]: https://en.wikipedia.org/wiki/Hobbit#Lifestyle 'Hobbit lifestyles'
• [1]: https://en.wikipedia.org/wiki/Hobbit#Lifestyle 'Hobbit lifestyles'
• [1]: https://en.wikipedia.org/wiki/Hobbit#Lifestyle (Hobbit lifestyles)
• [1]: 'Hobbit lifestyles'
• [1]: 'Hobbit lifestyles'
• [1]: (Hobbit lifestyles)

Markdown 1.1

You can place this second part of the link anywhere in your Markdown document. Some people place them immediately after the paragraph in which they appear while other people place them at the end of the document (like endnotes or footnotes).

An Example Putting the Parts Together

Free gambling no deposit. Say you add a URL as a standard URL link to a paragraph and it looks like this in Markdown:

Though it may point to interesting additional information, the URL as displayed really doesn't add much to the existing raw text other than making it harder to read. To fix that, you could format the URL like this instead:

In both instances above, the rendered output would be identical:

In a hole in the ground there lived a hobbit. Not a nasty, dirty, wet hole, filled with the ends of worms and an oozy smell, nor yet a dry, bare, sandy hole with nothing in it to sit down on or to eat: it was a hobbit-hole, and that means comfort.

and the HTML for the link would be:

Link Best Practices

Markdown applications don't agree on how to handle spaces in the middle of a URL. For compatibility, try to URL encode any spaces with %20.

Markdown 4 0 3 0

Images

To add an image, add an exclamation mark (!), followed by alt text in brackets, and the path or URL to the image asset in parentheses. You can optionally add a title after the URL in the parentheses.

The rendered output looks like this:

Linking Images

To add a link to an image, enclose the Markdown for the image in brackets, and then add the link in parentheses.

The rendered output looks like this:

Escaping Characters

To display a literal character that would otherwise be used to format text in a Markdown document, add a backslash () in front of the character.

The rendered output looks like this:

Markdown 4 0 3 X 2

* Without the backslash, this would be a bullet in an unordered list.

Characters You Can Escape

You can use a backslash to escape the following characters.

HTML

Many Markdown applications allow you to use HTML tags in Markdown-formatted text. This is helpful if you prefer certain HTML tags to Markdown syntax. For example, some people find it easier to use HTML tags for images. Using HTML is also helpful when you need to change the attributes of an element, like specifying the color of text or changing the width of an image.

To use HTML, place the tags in the text of your Markdown-formatted file.

The rendered output looks like this:

This word is bold. This word is italic.

HTML Best Practices

For security reasons, not all Markdown applications support HTML in Markdown documents. When in doubt, check your Markdown application's documentation. Some applications support only a subset of HTML tags.
