//! Compile-time embedded test fixtures for downstream crates.
//!
//! When the `test-fixtures` feature is enabled, this module exposes the
//! contents of `tests/fixtures/formats/` as `&'static [u8]` constants and
//! as directory handles.  Downstream crates can use these to write their
//! own integration tests without needing the raw files on disk.
//!
//! # Example
//!
//! ```ignore
//! use ragrig::fixtures;
//! let pdf_bytes: &[u8] = ragrig::fixtures::pdf::NEW_STATS;
//! ```

#[cfg(feature = "test-fixtures")]
pub mod pdf {
    use include_dir::{include_dir, Dir};
    /// All PDF fixtures.
    pub static DIR: Dir<'_> = include_dir!("$CARGO_MANIFEST_DIR/tests/fixtures/formats/pdf");
    /// `New_Stats.pdf` — a statistics textbook chapter.
    pub const NEW_STATS: &[u8] =
        include_bytes!("../tests/fixtures/formats/pdf/New_Stats.pdf");

    /// `Getting_started_with_R.Rmd` — introductory R tutorial.
    pub const GETTING_STARTED: &[u8] =
        include_bytes!("../tests/fixtures/formats/rmd/Getting_started_with_R.Rmd");

#[cfg(feature = "test-fixtures")]
pub mod html {

// ── Convenience: extract format to a temp directory ───────────────────────

/// Extract fixture files for the given format to a temporary directory.
///
/// Returns the directory path and the [`TempDir`] handle (which must be kept
/// alive — dropping it deletes the extracted files).  Callers should hold the
/// `TempDir` for the lifetime of any file I/O on the returned path.
///
/// Available formats: `"pdf"`, `"rmd"`, `"html"`.
///
/// This is the recommended entry point for downstream benchmarking crates
/// that need on-disk fixture files without vendoring them manually.
