See how it compares to a competitor in [this speed test](http://www.intmath.com/cg5/katex-mathjax-comparison.php). + * **Print quality:** KaTeX’s layout is based on Donald Knuth’s TeX, the gold standard for math typesetting. + * **Self contained:** KaTeX has no dependencies and can easily be bundled with your website resources. + * **Server side rendering:** KaTeX produces the same output regardless of browser or environment, so you can pre-render expressions using Node.js and send them as plain HTML. + +KaTeX supports all major browsers, including Chrome, Safari, Firefox, Opera, Edge, and IE 9 - IE 11. A list of supported commands can be found on the [wiki](https://github.com/Khan/KaTeX/wiki/Function-Support-in-KaTeX). + +## Usage + +You can [download KaTeX](https://github.com/khan/katex/releases) and host it on your server or include the `katex.min.js` and `katex.min.css` files on your page directly from a CDN: + +```html + + +``` + +#### In-browser rendering + +Call `katex.render` with a TeX expression and a DOM element to render into: + +```js +katex.render("c = \\pm\\sqrt{a^2 + b^2}", element); +``` + +If KaTeX can't parse the expression, it throws a `katex.ParseError` error. + +#### Server side rendering or rendering to a string + +To generate HTML on the server or to generate an HTML string of the rendered math, you can use `katex.renderToString`: + +```js +var html = katex.renderToString("c = \\pm\\sqrt{a^2 + b^2}"); +// '...' +``` + +Make sure to include the CSS and font files, but there is no need to include the JavaScript. Like `render`, `renderToString` throws if it can't parse the expression. + +#### Rendering options + +You can provide an object of options as the last argument to `katex.render` and `katex.renderToString`. Available options are: + +- `displayMode`: `boolean`. If `true` the math will be rendered in display mode, which will put the math in display style (so `\int` and `\sum` are large, for example), and will center the math on the page on its own line. If `false` the math will be rendered in inline mode. (default: `false`) +- `throwOnError`: `boolean`. If `true`, KaTeX will throw a `ParseError` when it encounters an unsupported command. If `false`, KaTeX will render the unsupported command as text in the color given by `errorColor`. (default: `true`) +- `errorColor`: `string`. A color string given in the format `"#XXX"` or `"#XXXXXX"`. This option determines the color which unsupported commands are rendered in. (default: `#cc0000`) +- `macros`: `object`. A collection of custom macros. Each macro is a property with a name like `\name` (written `"\\name"` in JavaScript) which maps to a string that describes the expansion of the macro. +- `colorIsTextColor`: `boolean`. If `true`, `\color` will work like LaTeX's `\textcolor`, and take two arguments (e.g., `\color{blue}{hello}`), which restores the old behavior of KaTeX (pre-0.8.0). If `false` (the default), `\color` will work like LaTeX's `\color`, and take one argument (e.g., `\color{blue}hello`). In both cases, `\textcolor` works as in LaTeX (e.g., `\textcolor{blue}{hello}`). + +For example: + +```js +katex.render("c = \\pm\\sqrt{a^2 + b^2}\\in\\RR", element, { + displayMode: true, + macros: { + "\\RR": "\\mathbb{R}" + } +}); +``` + +#### Automatic rendering of math on a page + +Math on the page can be automatically rendered using the auto-render extension. See [the Auto-render README](contrib/auto-render/README.md) for more information. + +#### Font size and lengths + +By default, KaTeX math is rendered in a 1.21× larger font than the surrounding +context, which makes super- and subscripts easier to read. You can control +this using CSS, for example: + +```css +.katex { font-size: 1.1em; } +``` + +KaTeX supports all TeX units, including absolute units like `cm` and `in`. +Absolute units are currently scaled relative to the default TeX font size of +10pt, so that `\kern1cm` produces the same results as `\kern2.845275em`. +As a result, relative and absolute units are both uniformly scaled relative +to LaTeX with a 10pt font; for example, the rectangle `\rule{1cm}{1em}` has +the same aspect ratio in KaTeX as in LaTeX. However, because most browsers +default to a larger font size, this typically means that a 1cm kern in KaTeX +will appear larger than 1cm in browser units. + +## Contributing + +See

include the following: + * + * - numArgs: The number of arguments the function takes. + * If this is the only property, it can be passed as a number + * instead of an element of a properties object. + * - argTypes: (optional) An array corresponding to each argument of the + * function, giving the type of argument that should be parsed. Its + * length should be equal to `numArgs + numOptionalArgs`. Valid + * types: + * - "size": A size-like thing, such as "1em" or "5ex" + * - "color": An html color, like "#abc" or "blue" + * - "original": The same type as the environment that the + * function being parsed is in (e.g. used for the + * bodies of functions like \textcolor where the + * first argument is special and the second + * argument is parsed normally) + * Other possible types (probably shouldn't be used) + * - "text": Text-like (e.g. \text) + * - "math": Normal math + * If undefined, this will be treated as an appropriate length + * array of "original" strings + * - greediness: (optional) The greediness of the function to use ungrouped + * arguments. + * + * E.g. if you have an expression + * \sqrt \frac 1 2 + * since \frac has greediness=2 vs \sqrt's greediness=1, \frac + * will use the two arguments '1' and '2' as its two arguments, + * then that whole function will be used as the argument to + * \sqrt. On the other hand, the expressions + * \frac \frac 1 2 3 + * and + * \frac \sqrt 1 2 + * will fail because \frac and \frac have equal greediness + * and \sqrt has a lower greediness than \frac respectively. To + * make these parse, we would have to change them to: + * \frac {\frac 1 2} 3 + * and + * \frac {\sqrt 1} 2 + * + * The default value is `1` + * - allowedInText: (optional) Whether or not the function is allowed inside + * text mode (default false) + * - numOptionalArgs: (optional) The number of optional arguments the function + * should parse. If the optional arguments aren't found, + * `null` will be passed to the handler in their place. + * (default 0) + * - infix: (optional) Must be true if the function is an infix operator. + * + * The last argument is that implementation, the handler for the function(s). + * It is called to handle these functions and their arguments. + * It receives two arguments: + * - context contains information and references provided by the parser + * - args is an array of arguments obtained from TeX input + * The context contains the following properties: + * - funcName: the text (i.e. name) of the function, including \ + * - parser: the parser object + * - lexer: the lexer object + * - positions: the positions in the overall string of the function + * and the arguments. + * The latter three should only be used to produce error messages. + * + * The function should return an object with the following keys: + * - type: The type of element that this is. This is then used in + * buildHTML/buildMathML to determine which function + * should be called to build this node into a DOM node + * Any other data can be added to the object, which will be passed + * in to the function in buildHTML/buildMathML as `group.value`. + */ + +function defineFunction(names, props, handler) { + if (typeof names === "string") { + names = [names]; + } + if (typeof props === "number") { + props = { numArgs: props }; + } + // Set default values of functions + var data = { + numArgs: props.numArgs, + argTypes: props.argTypes, + greediness: props.greediness === undefined ? 1 : props.greediness, + allowedInText: !!props.allowedInText, + allowedInMath: props.allowedInMath, + numOptionalArgs: props.numOptionalArgs || 0, + infix: !!props.infix, + handler: handler + }; + for (var i = 0; i < names.length; ++i) { + module.exports[names[i]] = data; + } +} + +// Since the corresponding buildHTML/buildMathML function expects a +// list of elements, we normalize for different kinds of arguments +var ordargument = function ordargument(arg) { + if (arg.type === "ordgroup") { + return arg.value; + } else { + return [arg]; + } +}; + +// A normal square root +defineFunction("\\sqrt", { + numArgs: 1, + numOptionalArgs: 1 +}, function (context, args) { + var index = args[0]; + var body = args[1]; + return { + type: "sqrt", + body: body, + index: index + }; +}); + +// Non-mathy text, possibly in a font +var textFunctionStyles = { + "\\text": undefined, "\\textrm": "mathrm", "\\textsf": "mathsf", + "\\texttt": "mathtt", "\\textnormal": "mathrm", "\\textbf": "mathbf", + "\\textit": "textit" +}; + +defineFunction(["\\text", "\\textrm", "\\textsf", "\\texttt", "\\textnormal", "\\textbf", "\\textit"], { + numArgs: 1, + argTypes: ["text"], + greediness: 2, + allowedInText: true +}, function (context, args) { + var body = args[0]; + return { + type: "text", + body: ordargument(body), + style: textFunctionStyles[context.funcName] + }; +}); + +// A two-argument custom color +defineFunction("\\textcolor", { + numArgs: 2, + allowedInText: true, + greediness: 3, + argTypes: ["color", "original"] +}, function (context, args) { + var color = args[0]; + var body = args[1]; + return { + type: "color", + color: color.value, + value: ordargument(body) + }; +}); + +// \color is handled in Parser.js's parseImplicitGroup +defineFunction("\\color", { + numArgs: 1, + allowedInText: true, + greediness: 3, + argTypes: ["color"] +}, null); + +// An overline +defineFunction("\\overline", { + numArgs: 1 +}, function (context, args) { + var body = args[0]; + return { + type: "overline", + body: body + }; +}); + +// An underline +defineFunction("\\underline", { + numArgs: 1 +}, function (context, args) { + var body = args[0]; + return { + type: "underline", + body: body + }; +}); + +// A box of the width and height +defineFunction("\\rule", { + numArgs: 2, + numOptionalArgs: 1, + argTypes: ["size", "size", "size"] +}, function (context, args) { + var shift = args[0]; + var width = args[1]; + var height = args[2]; + return { + type: "rule", + shift: shift && shift.value, + width: width.value, + height: height.value + }; +}); + +// TODO: In TeX, \mkern only accepts mu-units, and \kern does not accept +// mu-units.
