Options for reflowing text

Fields

line_length: usize

Target line length

break_on_sentences: bool

Whether to break on sentence boundaries when possible

preserve_breaks: bool

Whether to preserve existing line breaks in paragraphs

sentence_per_line: bool

Whether to enforce one sentence per line

semantic_line_breaks: bool

Whether to use semantic line breaks (cascading split strategy)

abbreviations: Option<Vec<String>>

Custom abbreviations for sentence detection Periods are optional - both “Dr” and “Dr.” work the same Custom abbreviations are always added to the built-in defaults

length_mode: ReflowLengthMode

How to measure string length for line-length comparisons

attr_lists: bool

Whether to treat {#id .class key=“value”} as atomic (unsplittable) elements. Enabled for MkDocs and Kramdown flavors.

myst_roles: bool

Whether to treat MyST inline roles ({role}`content`) as atomic (unsplittable) elements. Enabled for the MyST flavor so the colon inside {domain:role} is never used as a clause-break point.

require_sentence_capital: bool

Whether to require uppercase after periods for sentence detection. When true (default), only “word. Capital” is a sentence boundary. When false, “word. lowercase” is also treated as a sentence boundary. Does not affect ! and ? which are always treated as sentence boundaries.

max_list_continuation_indent: Option<usize>

Cap list continuation indent to this value when set. Used by mkdocs flavor where continuation is always 4 spaces regardless of checkbox markers.

defined_references: Option<HashSet<String>>

Defined reference labels for the surrounding document, used to decide whether a bare shortcut reference ([text]) is a real link (kept atomic during reflow) or literal bracketed prose (wrapped like normal text).

None means no reference information is available: every shortcut is treated as atomic. This is the safe default - it never splits a real link, at the cost of also not wrapping literal bracketed prose.

Some(set) enables definition-aware behavior: a shortcut is atomic only when its normalized label (see normalize_reference_label) is in the set. Full and collapsed reference links and reference images are always atomic regardless, because their ][ref] / [] syntax is an explicit link signal that does not depend on a definition being in scope.

atomic_spans: bool

Whether to hold emphasis/strong/strikethrough and code spans atomic during reflow. When true (default), these spans are treated as atomic units. When false, they can be wrapped word-by-word like normal text.

length_exemptions: LengthExemptions

Which of the checker’s line-length exemptions reflow mirrors when it measures a line. Empty measures the markdown as written.
