[Unreleased]

0.1.4 - 2026-05-31

Added

  • Criterion and profiling fixtures twitter.json and citm_catalog.json (simdjson-data) alongside canada.json.

Changed

  • Removed ParserContext::is_in_error_recovery; the whole-input parse driver now selects the error-recovery pass via internal Mode (Emit<false, false> vs Emit<true, false>). Custom parse drivers that relied on that field should pass the appropriate mode to the crate-private parse entry point instead.
  • cargo bench uses [profile.bench] tuned for throughput (lto, codegen-units = 1, no debug info). Sampling profilers and flamegraphs should use [profile.profiling] (debug = true, LTO off); profile.samply inherits profiling.
  • Guide AI-assistance notices on docs.rs use rustdoc’s .warning callout styling so they read correctly in dark and Ayu themes (replacing fixed light-theme colors).
  • The guide and capture! docs now document E0283 on disconnected or unused let rules (for example after commenting out the only one_of / .trace() use of a branch).

0.1.3 - 2026-05-23

Changed

  • improved error recovery of json example
  • changed docs for trace viewer

Fixed

  • label messed up error recognition if inner parser returned error

0.1.2 - 2026-05-20

Added

  • README files under examples/, examples/json/, and examples/mini_language/ with run commands and layout notes.

Changed

  • README: links (docs.rs, crates.io, LICENSE, CONTRIBUTING), trimmed AI/tracing sections, example table points at examples/*/README.md, general improvements.

Removed

  • The mini_script example and its unused fixtures under tests/data/mini_script/.

0.1.1 - 2026-05-19

Changed

  • docs.rs rustdoc includes scraped code from the json, mini_language, and mini_script examples on relevant API pages (doc-scrape-examples).

Fixed

  • docs.rs builds again: doc_auto_cfg (removed in Rust 1.92) is replaced with doc_cfg under the docsrs cfg.

0.1.0 - 2026-05-19

Changed

  • Minimum supported Rust version is 1.88 (stable let chains in if/while).
  • CI runs a nightly cargo doc with --cfg docsrs and the same features as docs.rs so removed or renamed rustdoc features are caught before publish.

0.1.0 - 2026-05-19

Added

  • Initial public release of marser, marser_macros, marser-trace-schema, and marser-trace-viewer.
  • PEG-style parser combinators with capture!, matcher-level backtracking, and error recovery.
  • Optional annotate-snippets feature for terminal diagnostics (ParserError::eprint, etc.).
  • Optional parser-trace feature and experimental trace schema / viewer crates.
  • Optional embed-guide feature for long-form rustdoc chapters (marser::guide).
  • Integration tests, JSON example grammar, and Criterion benchmarks in the repository.

Notes

  • Trace file formats and trace-related APIs may change in future releases; pin versions and read release notes when upgrading.
  • Macro expansion details are not a stability guarantee; use capture! and documented helpers as the public API.
