taskLists

default: true
Blackfriday flag:
Purpose: false turns off GitHub-style automatic task/TODO list generation

smartypants

default: true
Blackfriday flag: HTML_USE_SMARTYPANTS
Purpose: false disables smart punctuation substitutions, including smart quotes, smart dashes, smart fractions, etc. If true, it may be fine-tuned with the angledQuotes, fractions, smartDashes, and latexDashes flags (see below).

smartypantsQuotesNBSP

default: false
Blackfriday flag: HTML_SMARTYPANTS_QUOTES_NBSP
Purpose: true enables French style Guillemets with non-breaking space inside the quotes.

angledQuotes

default: false
Blackfriday flag: HTML_SMARTYPANTS_ANGLED_QUOTES
Purpose: true enables smart, angled double quotes. Example: "Hugo" renders to «Hugo» instead of “Hugo”.

fractions

default: true
Blackfriday flag: HTML_SMARTYPANTS_FRACTIONS
Purpose: false disables smart fractions.
Example: 5/12 renders to ⁵⁄₁₂(<sup>5</sup>&frasl;<sub>12</sub>).
Caveat: Even with fractions = false, Blackfriday still converts 1/2, 1/4, and 3/4 respectively to ½ (½), ¼ (¼) and ¾ (¾), but only these three.

smartDashes

default: true
Blackfriday flag: HTML_SMARTY_DASHES
Purpose: false disables smart dashes; i.e., the conversion of multiple hyphens into an en dash or em dash. If true, its behavior can be modified with the latexDashes flag below.

latexDashes

default: true
Blackfriday flag: HTML_SMARTYPANTS_LATEX_DASHES
Purpose: false disables LaTeX-style smart dashes and selects conventional smart dashes. Assuming smartDashes:
If true, -- is translated into – (–), whereas --- is translated into — (—).
However, spaced single hyphen between two words is translated into an en dash— e.g., "12 June - 3 July" becomes 12 June ndash; 3 July upon rendering.

hrefTargetBlank

default: false
Blackfriday flag: HTML_HREF_TARGET_BLANK
Purpose: true opens external links in a new window or tab.

plainIDAnchors

default true
Blackfriday flag: FootnoteAnchorPrefix and HeaderIDSuffix
Purpose: true renders any heading and footnote IDs without the document ID.
Example: renders #my-heading instead of #my-heading:bec3ed8ba720b970

extensions

default: []
Blackfriday flag: EXTENSION_*
Purpose: Enable one or more Blackfriday's Markdown extensions (if they aren't Hugo defaults).
Example: Include hardLineBreak in the list to enable Blackfriday's EXTENSION_HARD_LINK_BREAK

extensionsmask

default: []
Blackfriday flag: EXTENSION_*
Purpose: Enable one or more of Blackfriday's Markdown extensions (if they aren't Hugo defaults).
Example: Include autoHeaderIds as false in the list to disable Blackfriday's EXTENSION_AUTO_HEADER_IDS.
