Lyric

What changed in v2.5.1 — 2026-08-21

One fix, to a promise the formatter's own chapter makes.

Fixed

• lyric fmt breaks operator chains at the 100-column limit. A condition of three comparisons ran to 140 characters and stayed there, idempotently: BinaryDoc held no line opportunity at all, so a chain could not break however long it grew. The limit is documented as the tool's contract, and it now holds for expressions too.

  A chain that does not fit breaks before every operator of its precedence level, indented one step — the operator leads its line, as PEP 8, rustfmt and the .NET style default all settled on. The level breaks as a unit: a && b && c is one decision, so no staircase of nested pairs. A tighter level inside stays flat while the looser one breaks.

  One shape is deliberately left alone: a chain with an operand that breaks by itself — a match or if expression, a lambda with a block — stays as it is, because a group around it could never be flat and the chain would break for a reason that has nothing to do with the width.

  Formatted files can change shape: a lyric fmt --check in CI may report files that were clean before. Nothing in this repository's own corpus changed, which is how narrow the reformatting turned out to be.
