ESLint is Now Language-Agnostic: Linting JSON, Markdown, and Beyond
ESLint has added JSON and Markdown linting support with new officially-supported plugins, expanding its versatility beyond JavaScript.
@mathigon/euclid
Advanced tools
Euclid.ts is a Typescript library for 2D geometry. It contains classes for elements like points, lines, circles, and polygons, intersection detection, as well as SVG and Canvas drawing tools. It was developed for Mathigon.org, an award-winning mathematics education project.
All class instances are immutable: you need to create new copies rather than modifying their properties. This is mainly to facilitate fast change detection on downstream libraries.
Points: Point(x: number, y: number)
Lines: Line(p1: Point, p2: Point)
, Segment(p1: Point, p2: Point)
, Ray(p1: Point, p2: Point)
Polygons: Polygon(...points: Point[])
, Polyline(...points: Point[])
Rectangles: Rectangle(p: Point, w: number, h: number)
Circles: Circle(c: Point, r: number)
Ellipses: Ellipse(c: Point, a: number, b: number)
Arcs: Arc((c: Point, start: Point, angle: number))
, Sector((c: Point, start: Point, angle: number))
Angle: Angle(a: Point, b: Point, c: Point)
Bounds: Bounds(xMin: number, xMax: number, yMin: number, yMax: number)
Intersections: intsersection(...obj: GeoShape[])
Drawing: drawSVG(obj: GeoElement, options: SVGDrawingOptions)
, drawCanvas(ctx: CanvasRenderingContext2D, obj: GeoElement, options: CanvasDrawingOptions)
First, install Euclid.ts from NPM using
npm install @mathigon/euclid
Now, simply import all functions and classes you need, using
import {Point, Line} from '@mathigon/euclid'
