commonmark/ast
This module defines the Markdown AST used.
This AST can be used to manipulate markdown documents or render them with your own algorithm.
CommonMark defines two major types of elements which have a hierarchical relationship:
- A Document has many blocks.
- A block has zero or more inline elements that make up it’s content.
- Inline elements define the textual contents of the document.
Types
Block nodes are used to define the overall structure of a document.
pub type BlockNode {
HorizontalBreak
Heading(level: Int, contents: List(InlineNode))
CodeBlock(
info: Option(String),
full_info: Option(String),
contents: String,
)
HtmlBlock(html: String)
LinkReference(name: String, href: String)
Paragraph(contents: List(InlineNode))
BlockQuote(contents: List(BlockNode))
OrderedList(
contents: List(ListItem),
start: Int,
marker: OrderedListMarker,
)
UnorderedList(
contents: List(ListItem),
marker: UnorderedListMarker,
)
}

Documents contain all the information necessary to render a document, both structural and metadata.

Inline nodes are used to define the formatting and individual elements that appear in a document.
pub type InlineNode {
CodeSpan(contents: String)
Emphasis(contents: List(InlineNode), marker: EmphasisMarker)
StrongEmphasis(
contents: List(InlineNode),
marker: EmphasisMarker,
)

Text(contents: String)
Text content shouldn’t contain line breaks. See HardLineBreak and SoftLineBreak for the canonical representation of line breaks that renderers can make decisions about.

NamedEntity(name: String, codepoint: List(UtfCodepoint))
A named HTML entity. The CommonMark spec calls for these to be rendered into unicode instead of as HTML entities. Equivalent to
"&" <> name <> ";"
in HTML. -
NumericCharacterReference(codepoint: UtfCodepoint, hex: Bool)
Numeric character entity. The CommonMark spec calls for these to be rendered into unicode instead of as HTML entities. Equivalent to
"&" <> int.to_string(codepoint) <> ";"
in HTML.
