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
