It provides tools for processing front matter -//! in various formats (YAML, TOML, JSON) and building static sites with customizable templates. +//! The Frontmatter Generator is a command-line tool designed for extracting, validating, +//! and manipulating frontmatter in various formats, including YAML, TOML, and JSON. +//! It also provides static site generation capabilities when enabled. //! //! ## Features //! -//! - **Validation**: Ensure required front matter fields are present and correctly formatted. -//! - **Extraction**: Extract front matter in various formats and output it to a file or stdout. -//! - **Site Generation**: Build static sites with configurable content, output, and template directories. +//! - **Frontmatter Manipulation**: Extract and validate frontmatter from Markdown files. +//! - **Static Site Generation**: Build static sites with templates and structured content. +//! - **Multi-Format Support**: YAML, TOML, and JSON support. +//! - **Secure and Robust**: Implements secure file handling, input sanitisation, and logging. //! //! ## Usage //! -//! Use the command-line interface to interact with the tool: -//! //! ```bash -//! frontmatter-gen validate --file content.md --required title date author -//! frontmatter-gen extract --file content.md --format yaml --output frontmatter.yaml +//! # Extract frontmatter from a file +//! frontmatter-gen extract input.md --format yaml +//! +//! # Validate frontmatter for required fields +//! frontmatter-gen validate input.md --required title,date +//! +//! # Generate a static site //! frontmatter-gen build --content-dir content --output-dir public --template-dir templates //! ``` //! -//! ## Configuration +//! ## Environment Variables //! -//!
