Contents
API
processor().use(stringify[, options])
Configure the processor
to serialize mdast
syntax trees to Markdown.
options
Options can be passed directly, or passed later through processor.data()
.
options.gfm
Serialize with the required escapes for GFM compatible Markdown
(boolean
, default: true
).
- Escape pipes (
|
, for tables) - Escape colons (
:
, for literal URLs) - Escape tildes (
~
, for strike-through)
options.commonmark
Serialize for CommonMark compatible Markdown (boolean
,
default: false
).
- Serialize adjacent block quotes separately
- Escape more characters using slashes, instead of as entities
options.pedantic
⚠️ Pedantic was previously used to mimic old-style Markdown mode: no tables, no fenced code, and with many bugs. It’s currently still “working”, but please do not use it, it’ll be removed in the future.
options.entities
⚠️ entities
was previously used, but included bugs. It’s
currently still “working”, but please do not use it, it’ll be removed in
the future.
options.setext
Serialize headings, when possible, in Setext-style
(boolean
, default: false
). Uses =
for level one headings and -
for level two headings. Other
heading levels are serialized as ATX (respecting
closeAtx
).
options.closeAtx
Serialize ATX headings with the same amount of closing hashes as
opening hashes (boolean
, default: false
).
options.tableCellPadding
Create tables with a space between cell delimiters (|
)
and content (boolean
, default: true
).
options.tablePipeAlign
Align the delimiters (|
) between table cells so that
they all align nicely and form a grid (boolean
, default:
true
).
options.stringLength
Function passed to markdown-table
to detect the length of a table cell (Function
, default: s => s.length
).
Used to pad tables.
options.fence
Marker to use for fenced code blocks ('~'
or
'`'
, default: '`'
).
options.fences
Create code blocks with a fence instead of indentation if they have
no info string (boolean
, default: false
).
When false
, code blocks are indented. Code blocks with
an info string are always fenced.
options.bullet
Marker to use for the bullet of unordered list items
('-'
, '*'
, or '+'
, default:
'-'
).
options.listItemIndent
Style of indentation for list items ('tab'
,
'mixed'
or '1'
, default:
'tab'
).
'tab'
: use a tab stops (4 spaces)'1'
: use one space'mixed'
: use1
for tight andtab
for loose list items
options.incrementListMarker
Increment ordered list item numbers (boolean
, default:
true
).
When false
, all list item numbers will be the same.
options.tightDefinitions
Separate definitions with a single line feed (boolean
,
default: false
).
When false
, definitions will have blank lines between
them, similar to other blocks.
options.rule
Marker to use for thematic breaks / horizontal rules
('-'
, '*'
, or '_'
, default:
'*'
).
options.ruleRepetition
Number of markers to use for thematic breaks / horizontal rules
(number
, default: 3
). Musts be 3
or more.
options.ruleSpaces
Place a space between thematic break (horizontal rule) markers
(boolean
, default true
).
options.strong
Marker to use for importance ('_'
or '*'
,
default '*'
).
options.emphasis
Marker to use for emphasis ('_'
or '*'
,
default '_'
).
stringify.Compiler
Access to the compiler, if you need it.
Extending the Compiler
If the remark-stringify
plugin is used, it adds a Compiler
constructor function to the processor
. Other plugins can
add visitors to its prototype to change how Markdown is serialized.
The below plugin modifies a visitor to add an extra blank
line before headings with a rank of 2
.
.exports = gap
module
function gap() {
var Compiler = this.Compiler
var visitors = Compiler.prototype.visitors
var original = visitors.heading
.heading = heading
visitors
function heading(node) {
return (node.depth === 2 ? '\n' : '') + original.apply(this, arguments)
} }
Compiler#visitors
Map of types to visitors
(Object.<Function>
).
function visitor(node[, parent])
Serialize node
.
Parameters
node
(Node
) — Node to compileparent
(Parent
, optional) — Parent ofnode
. Not available on the root node
Returns
string
— Serialized given node
.
Security
As Markdown is sometimes used for HTML, and improper use of HTML can
open you up to a cross-site
scripting (XSS) attack, use of remark can also be unsafe. When going
to HTML, use remark in combination with the rehype
ecosystem, and use rehype-sanitize
to make the tree safe.
Use of remark plugins could also open you up to other attacks. Carefully assess each plugin and the risks involved in using them.
