m2-syn 0.7.1

Changes

• Reject ordinary and raw string literals after quote modifiers in the native parser. Inputs such as symbol "a" and symbol ///a/// now report a syntax error at the literal. This applies to symbol, local, global, threadLocal, and threadVariable.
• Retain the invalid cell, trivia, and neighboring cells during realtime parsing. Other quoted tokens remain accepted.
• License m2-syn and m2-syn-macros under either MIT or Apache-2.0, at your option, and include both license texts in each crate package.
• Update m2-syn-macros to 0.6.1 for its license metadata and files; macro behavior is unchanged.

Validation

• Workspace tests pass with and without default features.
• Both crate packages build, and packaged tests and all-target Clippy pass with warnings denied.
• All-feature rustdoc passes with warnings denied.
• The main package builds and tests against the released m2-syn-macros 0.6.1 dependency.

m2-syn 0.7.0

Changes

• Expose frame_recovering and FramedCells as a stateless API for cell framing. Callers receive completed cells alongside an optional incomplete tail, with original source spans and trivia preserved.
• For example, a = 1\nf = x -> ( yields the completed a = 1 cell and the incomplete f = x -> ( tail.
• CellStream::new retains its existing behavior and still rejects an incomplete final cell.

Validation

• Packaged tests and doctests pass with and without default features.
• Packaged all-target Clippy passes with warnings denied.
• All-feature rustdoc passes with warnings denied.
• Package builds against the released m2-syn-macros 0.6.0 dependency.

m2-syn 0.6.1

Changes

• Parse empty parentheses () as an empty sequence in the native parser.
• Update tree-sitter-macaulay2 to 6.3.2, whose grammar classifies empty parentheses as a sequence.

m2-syn 0.6.0

Relicense m2-syn and m2-syn-macros under MIT; store every comment in the slot where it occurs, so both parsers keep comments in place and Cell::comments() is now an accessor over the new Cell::leading_trivia; add a BOF beginning-of-file marker so parsed files emit their opening, closing, and inter-cell layout byte for byte; recover layout beside comments at delimiters and unclosed groups ending in a line comment; accept x <- y as a parallel assignment target; and retain unfinished string literals in the realtime parsers. SourceFile::new now takes BOF as its first argument. See CHANGELOG.md for migration details.

m2-syn 0.5.0

Split typed-node and traversal expansion into smaller rust-analyzer-friendly stages; expose public default visit, visit_mut, and fold functions; make traversal and pretty support unconditional; update tree-sitter-macaulay2 to 6.1.2; and require a real comma for ExprPack. See CHANGELOG.md for migration details.

m2-syn 0.4.0

This release replaces the flat generated CST schema with explicit nested
strutuct! declarations and substantially expands semantic visitor dispatch.

Highlights:

• Adds semantic operator, assignment, lambda, member-access, indexing, control,
  and related specialization families.
• Keeps Delimited, Punctuated, and ordinary vectors as transparent storage;
  delimiter boundaries are presented explicitly as Delimiter leaves.
• Adds CellTokenStream, CellTokenTree, and CellTokenGroup for framed parser
  tokens while retaining the common lexical token atoms.
• Treats adjacency as a binary operator and adds explicit augmented operators.
• Canonicalizes Token! punctuation across quoted fragments and arbitrary Rust
  token spacing.
• Adds the ProcMacro interface and LiteralReturnTypes transformation example.

Breaking migration:

• Replace PunctPair<L, P, R> with SeparatedPair<T, P>.
• Do not construct Punctuated for singleton values; it now requires a real
  separator.
• Update generated-node matches, visitors, folds, and constructors to the new
  nested semantic categories.
• Consume framed cells through CellTokenStream and CellTokenTree, projecting
  through to_token_stream or into_token_stream when lexical tokens are
  required.

See CHANGELOG.md for the complete release notes.

m2-syn 0.3.0

Highlights

• Split native processing into lexical TokenStream construction and cell-aware Tokenize, with structural cell boundaries and syntactic adjacency markers.
• Add NativeRealtimeParser for shell-oriented incremental parsing with incomplete-versus-invalid diagnostics.
• Preserve physical EOF, source identity, delimiter state, transformed cell contents, and typed comment ownership.
• Make pretty, tree-sitter, and walk independent features, including a renderer-independent PrettyNode API.
• Export quote_m2! through m2-syn and keep generated nodes under m2_syn::nodes.
• Keep exported syntax! expansions independent of downstream feature names.

See the changelog for the complete list of changes.

m2-syn 0.2.0

Highlights

• Expand the typed schema directly from syntax!; generated Rust files and the generator binary are no longer part of the workflow.
• Add recovering native parsing and retained incremental Tree-sitter parsing for editor-style incomplete source updates.
• Preserve token, delimiter, literal, punctuation, and source-aware spans consistently across both parser backends.
• Align native and Tree-sitter lowering for assignments, new installations, string escapes, empty components, qualified names, and float spellings.
• Simplify the public parser, traversal, quoting, delimiter, and token APIs while enforcing complete public documentation.

Both m2-syn and m2-syn-macros are versioned 0.2.0.

v0.1.0

First published release. Typed syntax trees, generated Visit/VisitMut/Fold traversal, and dual native/tree-sitter parser backends for Macaulay2.

Published to crates.io as m2-syn and m2-syn-macros.
