frontmatter 0.1.0

CRAN release: 2026-01-14

• Initial CRAN release.

• Extract and parse YAML or TOML front matter from text documents with read_front_matter() or parse_front_matter().

• Support for multiple front matter formats:

  • Standard YAML (--- delimiters) and TOML (+++ delimiters)
  • Comment-wrapped formats for R and Python files (# and #' prefixes)
  • PEP 723 Python inline script metadata

• Fast C++ parsing with graceful handling of incomplete front matter.

• Flexible parser integration: by default uses yaml12::parse_yaml() and tomledit::parse_toml() or you can provide custom parsers.
