//! Formatter configuration.
//!
//! EXTRACTION CANDIDATE: copied ~wholesale from arity's
//! `src/formatter/style.rs`. Keep close to arity's version so the eventual
//! shared-crate extraction stays mechanical. The LaTeX-specific [`WrapMode`]
//! (paragraph line-break policy, modeled on the `panache` formatter) is the one
//! field that diverges.

/// How the formatter lays out the line breaks *inside* a paragraph. Modeled on
/// panache's `WrapMode` (`crates/panache-formatter/src/config.rs`).
///
/// Only [`WrapMode::Reflow`] and [`WrapMode::Preserve`] are implemented today;
/// [`WrapMode::Sentence`] and [`WrapMode::Semantic`] are accepted but currently
/// fall back to [`WrapMode::Preserve`] behavior (see `formatter::core`).
#[derive(Debug, Clone, Copy, PartialEq, Eq, Default)]
pub enum WrapMode {
    /// Greedy fill: pack words up to `line_width`, breaking only where the next
    /// word would not fit. The default.
    #[default]
    Reflow,
    /// Wrap after each sentence (one sentence per line). *Not yet implemented —
    /// falls back to [`WrapMode::Preserve`].*
    Sentence,
    /// Semantic line breaks (<https://sembr.org/>): keep authored breaks and add
    /// breaks at sentence boundaries. *Not yet implemented — falls back to
    /// [`WrapMode::Preserve`].*
    Semantic,
    /// Leave paragraph line breaks exactly as authored (only collapse trailing
    /// whitespace and blank-line runs, as before reflow existed).
