# CHANGELOG
## v0.2.2
- Improved mdBook preprocessing performance
- Skips Markdown parser/cmark rewriting for chapters that cannot contain `plot` / `plotly` blocks
- Injects the Plotly HTML header only when a chart is successfully generated
- Added complete Markdown chapter coverage for mixed prose, regular code fences, and plot fences
- Refined map parser internals
- Split map lookup, expression evaluation, and color parsing into focused modules while preserving existing public imports
- Implemented `reuse-slab` behavior for expression evaluation modes
- Reduced per-item allocation in `g-number-list` generation
## v0.2.2-beta
- Added TOML chart input support
- Added the [`toml`](Cargo.toml:23) dependency and a new [`PlotlyInputType::TOMLInput`](src/preprocessor/config.rs:82) variant
- Added [`handle_toml_input()`](src/code_handler.rs:35) to convert TOML into [`serde_json::Value`](src/code_handler.rs:8) before reusing the existing plot parser
- Added regression coverage in [`tests/test_code_handler.rs`](tests/test_code_handler.rs:55) for direct TOML handling and config-driven input dispatch
## v0.2.2-alpha
- Refined layout parser release-prep cleanup
- Normalized axis `type` error messages in [`parse_axis_obj()`](src/code_handler/plot_obj_parser/layout_parser.rs:256) to match the field-oriented style already used by [`translate_with_config!()`](src/macros.rs:36) and [`translate_enum_with_config!()`](src/macros.rs:66)
- Kept axis parsing on explicit [`ParseContext`](src/code_handler/parse_context.rs:4) / [`MapEvalConfig`](src/preprocessor/config.rs:61) propagation without reintroducing hidden defaults
- Added an axis regression test in [`tests/test_code_handler.rs`](tests/test_code_handler.rs) covering `map.*`-backed `range`, `tick_prefix`, `tick_suffix`, `title`, `anchor`, `overlaying`, `show_tick_labels`, `auto_margin`, `fixed_range`, and axis `type`
- Updated release documentation
- Clarified that parser migration work favors [`translate_with_config!()`](src/macros.rs:36) and [`translate_enum_with_config!()`](src/macros.rs:66) over legacy [`translate!()`](src/macros.rs:29) in active parsing paths
- Documented `map-eval` / `map-parser-extensions` behavior more explicitly in user-facing docs
- Adjusted configs
- Removed `offline_js_sources`
## v0.2.1
- Refined parser migration toward explicit [`MapEvalConfig`](src/preprocessor/config.rs:61) propagation
- Replaced top-level legacy [`translate!()`](src/macros.rs:29) usage in [`parse_config_obj()`](src/code_handler/plot_obj_parser/layout_parser.rs:8) and [`parse_layout_obj()`](src/code_handler/plot_obj_parser/layout_parser.rs:59) with explicit [`translate_with_config!()`](src/macros.rs:36) entrypoints
- Updated tests to validate the migration path remains stable
- Added a layout/config regression case in [`tests/test_code_handler.rs`](tests/test_code_handler.rs) covering `map.*`-backed title, legend, axis range, and config parsing
## v0.2.1-beta
- Refined parser migration toward explicit [`MapEvalConfig`](src/preprocessor/config.rs:61) propagation
- Migrated trace parsers to consume [`ParseContext`](src/code_handler/parse_context.rs:4) instead of raw `map` where applicable
- Removed [`must_translate()`](src/code_handler/until.rs:29) and migrated remaining translation paths to explicit [`ParseContext`](src/code_handler/parse_context.rs:4) / config-driven helpers
- Threaded active map-eval config through generator parsing paths in [`src/code_handler/until.rs`](src/code_handler/until.rs)
- Reused shared helpers like [`parse_marker()`](src/code_handler/plot_obj_parser/common.rs:7) and [`parse_color_bar()`](src/code_handler/plot_obj_parser/common.rs:59) to reduce duplicated translation logic
- Slimmed trace registry dispatch in [`trace_registry.rs`](src/code_handler/plot_obj_parser/trace_registry.rs:1)
- Removed registry-side `.map(into_trace)` adaptation
- Moved trait-object conversion boundaries down into parser modules via `*_trace()` entrypoints
- Updated tests to validate the migration path remains stable
