badness 0.6.0

//! Formatter configuration.
//!
//! The LaTeX-specific [`WrapMode`] (paragraph line-break policy, modeled on the
//! `panache` formatter) is the one field specific to badness.

/// How the formatter lays out the line breaks *inside* a paragraph. Modeled on
/// panache's `WrapMode` (`crates/panache-formatter/src/config.rs`).
///
/// The sentence-boundary detection behind [`WrapMode::Sentence`] and
/// [`WrapMode::Semantic`] is a per-language abbreviation profile
/// (`formatter::sentence`); the language and any user no-break abbreviations are
/// resolved from config into the [`SentenceOptions`](super::SentenceOptions)
/// threaded through the lowering.

    /// long sentence stays on one line.

    /// breaks *and* add a break after each sentence. Like [`WrapMode::Sentence`]

    /// author placed a break (no comma/colon detection).

    /// whitespace and blank-line runs, as before reflow existed).
