Indentation in markdown is complex as lists and indented code interfere in
unexpected ways.
Fenced code has more features than indented code: it can specify a
programming language.
Since CommonMark took the idea of fenced code from GFM,
fenced code became widely supported.
Due to this, it’s recommended to configure this rule with 'fenced'
.
remark-stringify
always formats code blocks as
fenced.
Pass fences: false
to only use fenced code blocks when they have a
language and as indented code otherwise.
