ktsu.Frontmatter

A .NET library for processing and manipulating YAML frontmatter in markdown files.

Features

Extract, add, replace, and remove frontmatter from markdown documents
Combine multiple frontmatter sections into a single section
Standardize property names using intelligent matching
Sort properties according to standard conventions
Merge similar properties using different strategies
High performance with caching for repeated operations

Installation

dotnet add package ktsu.Frontmatter

Usage

using ktsu.Frontmatter;

// Extract frontmatter from a markdown document
string markdown = File.ReadAllText("document.md");
var frontmatter = Frontmatter.ExtractFrontmatter(markdown);

// Add frontmatter to a document
var properties = new Dictionary<string, object>
{
    { "title", "My Document" },
    { "date", DateTime.Now },
    { "tags", new[] { "documentation", "markdown" } }
};
string withFrontmatter = Frontmatter.AddFrontmatter(markdown, properties);

// Replace frontmatter
string replaced = Frontmatter.ReplaceFrontmatter(markdown, properties);

// Remove frontmatter
string withoutFrontmatter = Frontmatter.RemoveFrontmatter(markdown);

// Combine multiple frontmatter sections
string combined = Frontmatter.CombineFrontmatter(markdown);

// Customize property naming and ordering
string customized = Frontmatter.CombineFrontmatter(
    markdown, 
    FrontmatterNaming.Standard,  // Standardize property names
    FrontmatterOrder.Sorted,     // Sort properties in standard order
    FrontmatterMergeStrategy.Conservative // Merge similar properties
);

// Extract just the document body (content after frontmatter)
string body = Frontmatter.ExtractBody(markdown);

Advanced Features

Property Naming

Control how property names are handled:

FrontmatterNaming.AsIs: Keep property names as-is
FrontmatterNaming.Standard: Standardize property names using common conventions

Property Ordering

Control how properties are ordered:

FrontmatterOrder.AsIs: Keep properties in the order they appear
FrontmatterOrder.Sorted: Sort properties according to standard conventions

Merge Strategies

Control how similar properties are merged:

FrontmatterMergeStrategy.None: Do not merge any properties
FrontmatterMergeStrategy.Conservative: Only merge properties using predefined mappings
FrontmatterMergeStrategy.Aggressive: Merge properties using basic pattern matching
FrontmatterMergeStrategy.Maximum: Merge properties using semantic analysis
