Function: parseIndentedBlocks()

parseIndentedBlocks(src, config, lexer): { items: ParsedBlock[]; raw: string; } | undefined

Defined in: blockslides/packages/core/src/utilities/markdown/parseIndentedBlocks.ts:77

Parses markdown text into hierarchical indented blocks with proper nesting.

This utility handles:

• Line-by-line parsing with pattern matching
• Hierarchical nesting based on indentation levels
• Nested content collection and parsing
• Empty line handling
• Content dedenting for nested blocks

The key difference from flat parsing is that this maintains the hierarchical structure where nested items become nestedTokens of their parent items, rather than being flattened into a single array.

Parameters

src

string

The markdown source text to parse

config

BlockParserConfig

Configuration object defining how to parse and create tokens

lexer

Markdown lexer for parsing nested content

inlineTokens

(src) => any[]

blockTokens

(src) => any[]

Returns

{ items: ParsedBlock[]; raw: string; } | undefined

Parsed result with hierarchical items, or undefined if no matches

Example

const result = parseIndentedBlocks(src, {
  itemPattern: /^(\s*)([-+*])\s+\[([ xX])\]\s+(.*)$/,
  extractItemData: (match) => ({
    indentLevel: match[1].length,
    mainContent: match[4],
    checked: match[3].toLowerCase() === 'x'
  }),
  createToken: (data, nestedTokens) => ({
    type: 'taskItem',
    checked: data.checked,
    text: data.mainContent,
    nestedTokens
  })
}, lexer)
