If `true`, display math renders flush left, like `\documentclass[fleqn]` in LaTeX. +- `throwOnError`: `boolean`. If `true` (the default), KaTeX will throw a `ParseError` when it encounters an unsupported command or invalid LaTeX. If `false`, KaTeX will render unsupported commands as text, and render invalid LaTeX as its source code with hover text giving the error, in the color given by `errorColor`. +- `errorColor`: `string`. A color string given in the format `"#XXX"` or `"#XXXXXX"`. This option determines the color that unsupported commands and invalid LaTeX are rendered in when `throwOnError` is set to `false`. (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, or a function that accepts an instance of `MacroExpander` as first argument and returns the expansion as a string. `MacroExpander` is an internal API and subject to non-backwards compatible changes. See [`src/macros.js`](https://github.com/KaTeX/KaTeX/blob/master/src/macros.js) for its usage. Single-character keys can also be included in which case the character will be redefined as the given macro (similar to TeX active characters). *This object will be modified* if the LaTeX code defines its own macros via `\gdef`, which enables consecutive calls to KaTeX to share state. +- `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}`). +- `maxSize`: `number`. All user-specified sizes, e.g. in `\rule{500em}{500em}`, will be capped to `maxSize` ems. If set to `Infinity` (the default), users can make elements and spaces arbitrarily large. +- `maxExpand`: `number`. Limit the number of macro expansions to the specified number, to prevent e.g. infinite macro loops. If set to `Infinity`, the macro expander will try to fully expand as in LaTeX. (default: 1000) +- `allowedProtocols`: `string[]`. Allowed protocols in `\href`. Use `_relative` to allow relative urls, and `*` to allow all protocols. (default: `["http", "https", "mailto", "_relative"]`) +- `strict`: `boolean` or `string` or `function` (default: `"warn"`). If `false` or `"ignore`", allow features that make writing LaTeX convenient but are not actually supported by (Xe)LaTeX (similar to MathJax). If `true` or `"error"` (LaTeX faithfulness mode), throw an error for any such transgressions. If `"warn"` (the default), warn about such behavior via `console.warn`. Provide a custom function `handler(errorCode, errorMsg, token)` to customize behavior depending on the type of transgression (summarized by the string code `errorCode` and detailed in `errorMsg`); this function can also return `"ignore"`, `"error"`, or `"warn"` to use a built-in behavior. A list of such features and their `errorCode`s: + - `"unknownSymbol"`: Use of unknown Unicode symbol, which will likely also + lead to warnings about missing character metrics, and layouts may be + incorrect (especially in terms of vertical heights). + - `"unicodeTextInMathMode"`: Use of Unicode text characters in math mode. + - `"mathVsTextUnits"`: Mismatch of math vs. text commands and units/mode. + - `"commentAtEnd"`: Use of `%` comment without a terminating newline. + LaTeX would thereby comment out the end of math mode (e.g. `$`), + causing an error. + + A second category of `errorCode`s never throw errors, but their strictness + affects the behavior of KaTeX: + - `"newLineInDisplayMode"`: Use of `\\` or `\newline` in display mode + (outside an array/tabular environment).
