Release notes

v0.20.8

Added — consumer-controllable forest parsing

Downstream consumers that generate a parser table with grammargen can now opt their own grammar into the GSS-forest GLR fast path without forking gotreesitter, via three surfaces:

• Language.WantsForest — Go field; gob-serialized, so it's baked into GenerateLanguageAndBlob output and backward-compatible.
• grammargen.Grammar.WantsForest — Go flag on the grammar IR, plumbed onto the assembled Language.
• "gotreesitter": { "wantsForest": true } in grammar.json — declarative; read by ImportGrammarJSON and mirrored back by ExportGrammarJSON only when set, so standard grammars' output is byte-unchanged.

Built-in languages keep their curated, byte-range parity-certified forest defaults (behavior unchanged). Consumer opt-in is at the consumer's responsibility — the forest's decline→production fallback still prevents hard failures on declined inputs, but a clean-but-different tree is the consumer's to own. ExtendGrammar inherits the flag from its base grammar.

Full Changelog: odvcencio/gotreesitter@v0.20.7...v0.20.8

v0.20.7

Fixed

• Parser timeout and cancellation budgets now flow through the parser loop, recovery reparses, result compatibility/finalization, and Go normalization, so strict parses stop consistently instead of continuing unbounded work after the primary parse (#114, #128).
• F# external-scanner keyword dedent fallback now guards empty indentation stacks for then, and, with, else, elif, and end, preventing scanner panics on malformed or edge-case indentation (#129, #130).
• Swift if … else if … trailing-closure ambiguity recovery now follows the whole chain and requires a byte-faithful reparse, preventing collapsed function declarations from being accepted (#131, #132).

v0.20.6

Patch release for parser recovery correctness, grammargen parity, and the forest/performance workstream merged after v0.20.5.

Added

• Strict parse variants return ErrParseStoppedEarly for timeout, cancellation, token-source EOF, and parser safety-limit partial trees while preserving the returned tree for diagnostics.
• NodeAtByte and NamedNodeAtByte helpers on Tree and Node for editor offset lookup without hand-written tree walks.
• One-pass code-understanding helpers for common definition spans, call references, heritage edges, and enclosing-definition lookup.
• Benchmarks comparing the one-pass code-understanding helpers against the tags-query path for both parse-plus-inspect and already-parsed trees.
• grammars.LoadLanguage(name, blob) attaches registered external scanners and external lex-state tables when loading raw grammar blobs.
• Language.Size() reports approximate decoded table and lookup-cache bytes for diagnostics and cache policy decisions.

Fixed

• JavaScript, TypeScript, and TSX automatic-semicolon scanning now preserves standalone block statements before simple assignments such as {a}b=c, matching the C parser on minified bundle shapes (#111).
• Large Go files with wide table-driven literals now have an opt-in Cobra regression gate so release validation catches parser stack overflows like the ParserPool.Parse crash reported against command_test.go and completions_test.go (#110).

[0.20.8] - 2026-07-01

Adds consumer-controllable forest parsing.

Added

• Downstream consumers that generate a parser table with grammargen can opt their own grammar into the GSS-forest GLR fast path without forking, via three surfaces: the Language.WantsForest field (gob-serialized into blobs), the grammargen.Grammar.WantsForest flag, and a declarative "gotreesitter": { "wantsForest": true } object in grammar.json (read by ImportGrammarJSON, mirrored back by ExportGrammarJSON only when set, so standard grammars' output is unchanged). Built-in languages keep their curated, byte-range parity-certified forest defaults; consumer opt-in is at the consumer's responsibility, with the forest's decline→production fallback still preventing hard failures on declined inputs. ExtendGrammar inherits the flag from its base grammar (#134).

[0.20.7] - 2026-06-29

Patch release for parser timeout propagation and targeted language recovery scanner fixes merged after v0.20.6.

Fixed

• Parser timeout and cancellation budgets now flow through the parser loop, recovery reparses, result compatibility/finalization, and Go normalization, so strict parses stop consistently instead of continuing unbounded work after the primary parse (#114, #128).
• F# external-scanner keyword dedent fallback now guards empty indentation stacks for then, and, with, else, elif, and end, preventing scanner panics on malformed or edge-case indentation (#129, #130).
• Swift if … else if … chains no longer collapse the enclosing function to _modifierless_function_declaration_no_body (#131). The trailing-closure ambiguity recovery now follows the whole if/else-if chain — the chained if keyword is swallowed into an ERROR node, so it is discovered by scanning from the body's matching close brace — and requires a byte-faithful reparse so a partially-bracketed chain (which silently truncates without an ERROR node) is rejected rather than accepted (#132).

[0.20.6] - 2026-06-28

Patch release for parser recovery correctness, grammargen parity, and the forest/performance workstream merged after v0.20.5.

Added

• Strict parse variants return ErrParseStoppedEarly for timeout, cancellation, token-source EOF, and parser safety-limit partial trees while preserving the returned tree for diagnostics.
