@@ -7,7 +7,7 @@ You can provide an object of options as the last argument to [`katex.render` and
- `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` (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. 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.
- `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/Khan/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)
