Updates similar from 3.2.0 to 3.2.1

Changelog

Sourced from similar's changelog.

3.2.1

• Improved real-world diffing performance substantially without changing the produced diffs. On a corpus of real source file revisions, line diffs run about 4x faster with Algorithm::Myers, 5x faster with Algorithm::Histogram, and 2.5x faster with Algorithm::Patience; word diffs run about 2x faster. This comes from a faster line tokenizer, a SipHash-1-3 content hash that consumes whole words (randomly keyed with std), cheaper integer-keyed lookup tables, hashing only the changed middle of Myers line diffs, flat occurrence tables in Histogram, and a gap buffer in the compaction pass that was quadratic on diffs with many ops. Allocation counts and peak memory dropped as well; in particular one sided and heavily unbalanced inputs no longer build index structures proportional to the larger side for Algorithm::Hunt, Algorithm::Histogram, and Algorithm::Patience.
• Fixed Algorithm::Histogram overflowing the stack on inputs with many scattered changes. Pending ranges are now tracked on the heap, so stack usage no longer grows with the number of anchors. #105
• Fixed TextMerge::labels writing carriage returns and newlines verbatim into conflict markers, which let a label add lines to the output that looked like merged content. Line terminators in labels are now replaced with spaces. #101

Updates tree-sitter-dart from 0.2.0 to 0.3.0

Changelog

Sourced from tree-sitter-dart's changelog.

[0.3.0] - 2026-10-25

Dart 3.12 and 3.13 support, and node names taken from the Dart specification. Breaking: nine nodes are renamed and several trees change shape. The README describes the naming contract.

Added

• Dart 3.13 primary constructors, a preview in 3.12 behind primary-constructors:
  • the header form on classes and enums, as primary_constructor: class User(final String name);
  • the this : initializers { body } member, as primary_constructor_body_signature
  • abbreviated new(), new name() and factory constructors in the body
  • ; as an empty body on class, mixin, enum, extension and extension type declarations
  • final on extension type representation variables
• Dart 3.12 private named parameters ({required this._x}). They already parsed, and tests now pin them.
• The 33 reserved words are an ABI 15 reserved set, so var x = for + 0; is an ERROR. Built-in identifiers (get, set, required, mixin, ...) remain usable as identifiers.
• await and yield parse as identifiers where the keyword form cannot, as the analyzer allows outside async and generator bodies.
• documentation_comment for /// lines and /** */ blocks.
• Supertypes _expression and _binary_expression.
• A cascade node holding the receiver and its cascade_sections.
• Named operator nodes under an operator: field: additive_operator, multiplicative_operator, shift_operator, equality_operator, bitwise_operator and increment_operator, next to the existing relational_operator.
• Fields: condition: on if_statement, guard: on when guards, default_value: on parameter defaults, name: on function-typed, this. and super. parameters, type: on on clauses.
• Highlights for extension type representations, record and pattern field names, pattern variables, dot shorthands and for-in variables. rethrow is a keyword.
• Tags: @reference.call for cascade and dot-shorthand calls, @reference.class for new, const and generic constructor invocations, @reference.implementation for implemented interfaces, and operator methods by their operator.
• Tooling, described in the README and tools/corpus/README.md:
  • npm run parse -- file.dart parses with this checkout's grammar.
  • tools/analyzer_ast compares trees with the Dart analyzer's AST (dump, compare, crossings, recovery).
  • The corpus gate counts analyzer-valid files only, requires failures to match known_failures.txt, fails on AST crossings not listed in known_ast_crossings.txt, and flags zero-width recovery nodes.
