fragments.html - Split page content into searchable fragments
|
|
|
|
This partial processes a Hugo page and splits its content into fragments based on headings,
|
|
creating a data structure suitable for search indexing. It supports different fragment types
|
|
and handles hierarchical heading structures (h1, h2).
|
|
|
|
Parameters:
|
|
- .context (Page): The Hugo page to process
|
|
- .type (string): Fragment type - "content" (default), "heading", "title", or "summary"
|
|
|
|
Returns:
|
|
- dict: Map of heading keys to content fragments
|
|
|
|
Example:
|
|
Input page with content:
|
|
# Introduction
|
|
This is the intro text.
|
|
## Setup
|
|
Setup instructions here.
|
|
# Configuration
|
|
Config details here.
|
|
|
|
Output (type "content"):
|
|
{
|
|
"": "This is the intro text.",
|
|
"intro#Introduction": "This is the intro text. Setup instructions here.",
|
|
"setup#Setup": "Setup instructions here.",
|
|
"config#Configuration": "Config details here."
|
|
}
|
|
|
|
Fragment types:
|
|
- "content": Splits page content by headings (default)
|
|
- "heading": Returns heading keys with empty content
|
|
- "title": Returns empty content (title handled elsewhere)
|
|
- "summary": Returns page summary only
