# Changelog

## [2.3.3] - 2026-09-02

### Changed
- Updated dependencies: `@thednp/dommatrix` `^3.1.2`

## [2.3.2] - 2026-09-02

### Fixed
- `T`/`t` smooth-quadratic shorthand without a preceding `Q`/`q`/`T`/`t` now correctly uses the current point as control point per the SVG spec ([#64](https://github.com/thednp/svg-path-commander/pull/64), thanks @nattyluke) — `normalizeSegment` (`src/process/normalizeSegment.ts:4`), `getPathBBox` (`src/util/getPathBBox.ts:12`) and `getTotalLength` (`src/util/getTotalLength.ts:12`) previously reflected a `0`-defaulted control point, so a `t` following a non-`Q` command (e.g. Illustrator `c...t` output) produced an inflated control/bbox/length (thanks @nattyluke)

### Changed
- Updated dev dependencies: `@types/node` `^26.4.1`, `vitest` / `@vitest/*` `^4.1.11`, `happy-dom` `^20.12.2`, `vite` `^8.2.2`
- Rebuilt `dist` and `docs` bundles

## [2.3.1] - 2026-08-05

### Changed
- Updated `@thednp/dommatrix` to `^3.1.1` — the 3.1.x line carries the shim's matrix-math rework (specialized `translate` / `scale` / `skew` / `multiply` and constructor fast paths), which directly accelerates the 3D transform path through `getSVGMatrix()` and `projection2d()`; 3.1.1 makes `setMatrixValue()` mutate the instance in place and return `this`, matching native `DOMMatrix` (SVGPathCommander does not use `setMatrixValue()`, so output is byte-identical and the 2D single-pass fast path is untouched)
- Rebuilt `dist` and `docs` bundles

## [2.3.0] - 2026-08-04

### Added
- `pnpm bench` — head-to-head benchmark against the [SvgPath](https://github.com/fontello/svgpath) library (vendored reference in `scripts/svgpath/`), comparing parse / bbox / transform / string output, with results embedded in the README

### Changed
- **Performance**: allocation-free parsing — `scanParam()` converts validated number substrings without allocating new strings, `finalizeSegment()` builds segments with pre-sized arrays and index-based slicing instead of `splice()`
- **Performance**: single-pass 2D transforms — `transformPath()` now uses a dedicated `transform2D()` fast path that transforms segments in place (no per-segment absolutize / copy / DOMMatrix projection), falling back to the 3D-capable `iterate()` path for 3D matrices; output is byte-identical to the previous implementation (~2.8x faster 2D transforms)
- **Performance**: fast 2D branch in `projection2d()`, char-code based command detection in `iterate()` / `getPathBBox()`, allocation-free rounding in `pathToString()`, and a dedicated `C` case in `absolutizeSegment()`
- Rebuilt `dist` and `docs` bundles

## [2.2.4] - 2026-08-04
### Fixed
- Build warnings: UMD bundle now uses a dedicated `src/browser.ts` entry so the `SVGPathCommander` global remains the class itself (no mixed-exports namespace), and the `output.dir`/`output.file` conflict is resolved — tree-shaking, named exports and type declarations are unaffected
- ESM bundle exports the `SVGPathCommander` named export alongside the default, with all types available in `dist/index.d.ts`


## [2.2.3] - 2026-08-04

### Added
- Named `SVGPathCommander` export alongside the default export for better JSR documentation rendering
- Full JSDoc coverage for all class statics, instance properties, getters and every interface / type member — zero undocumented symbols per `deno doc --json` on both `index` and `util` entry points
- JSR `./util` subpath export in `deno.json`, mirroring the npm `svg-path-commander/util` entry

### Changed
- Documentation moved from the GitHub wiki into the repository `wiki/` folder — the GitHub-hosted wiki pages are no longer available, and the README and wiki pages now reference the local `wiki/` folder instead
- Merged `NPM.md` and `JSR.md` into a single `Installation.md` (npm, pnpm, bun, Deno/JSR and CDN installation)
- Updated `Usage-Examples.md` with corrected output values verified against the current implementation
- Rebuilt `dist` and `docs` bundles

## [2.2.2] - 2026-08-03

### Added
- `getBezierLengthAtT()` / `bezierLengthAtT()` — arc length up to a `t` ratio via Gauss-Legendre quadrature
- `arcLength()` / `arcLengthAtAngle()` / `arcLengthBetween()` — Gauss-Legendre ellipse arc length helpers
- Static-method cross-consistency tests (length/point lookup, conversions, transforms, geometry measurements, intersections)
- Native browser API parity tests — `getBBox()`, `getTotalLength()`, `getPointAtLength()` verified against real Chromium

### Fixed
- `getPointAtLength()` returning the start of the next segment at interior distances on a `Z` (closing line) segment (#61)
- `getPointAtLength()` returning stale coordinates for distances beyond the path end
- Arc length accuracy for `getTotalLength()` and `getPointAtLength()` (Gauss-Legendre quadrature)
- Bezier / quad length accuracy for arc-length sampling in `cubicTools` and `quadTools`
- Deno minimum-dependency-age policy blocking fresh `@thednp/dommatrix` releases — `minimumDependencyAge` disabled in `deno.json` (mirrors the pnpm `minimumReleaseAgeExclude` in `pnpm-workspace.yaml`)

### Changed
- Migrated tests to Vitest browser mode (Playwright Chromium) with Istanbul coverage — 100% line, branch, function and statement coverage
- Updated test fixtures and expected values to match the current implementation
- Rebuilt `dist` and `docs` bundles
- Full Deno / JSR compatibility — `deno.json` publishing as `@thednp/svg-path-commander`, `deno task` equivalents for test / check / lint / build, `.ts` extensions on all relative imports and explicit return types across the public API; `deno check src`, `deno lint src` and `deno publish --dry-run` all clean
- Upgraded `@thednp/dommatrix` to v3.0.6 and toolchain (tsdown, Vite, Vitest, pnpm 11)

### Added
- `llms.txt` with an LLM-friendly project summary
- README installation section for JSR (`deno add jsr:@thednp/svg-path-commander`, raw TypeScript import) and JSR badge fix

## [2.2.1] - 2026-04-06

### Added
- Reorganized intersection tools into `src/intersect/` — `pathsIntersection()`, `boundingBoxIntersect()`, `isPointInsideBBox()`, `interHelper()`

### Changed
- tsdown config and CI workflow versions, `.npmignore` cleanup, demo fixes

## [2.2.0] - 2026-04-06

### Added
- **Path intersection** — `pathsIntersection()`, `boundingBoxIntersect()`, `isPointInsideBBox()`
- **Path equalization** — `equalizePaths()`, `equalizeSegments()` for matching segment counts
- Full JSDoc coverage with `@param`, `@returns`, `@example` tags
- New demo page for path morphing
- `polyonArea` utility
- `isMultiPath()`, `isClosedPath()`, `isPolygonArray()` and `isPolylineArray` utilities
- CHANGELOG.md and AGENTS.md

### Removed
- badge workflow and script in package.json

### Fixed
- **pathToCurve** inconsistencies
- reworked all exports as named exports

### Changed
- Added a separate export for utilities in `svg-path-commander/util`
- Migrated test runner from Playwright to happy-dom
- updated tests
- tsdown bundler
