* Sets an arbitrary attribute on the span. Warning: use this wisely. Not * all browsers support attributes the same, and having too many custom

* Return the font metrics for this size.

* Returns a new options object with the same properties as "this". Properties * from "extension" will be copied to the new options object.

* Sets an attribute on a MathML node. MathML depends on attributes to convey a * semantic content, so this is used heavily.

* Return an options object with the given style. If `this.style === style`, * returns `this`.

* Considers the current look ahead token as consumed, * and fetches the one after that as the new look ahead.

* Get the current value of a name, or `undefined` if there is no value. * * Note: Do not use `if (namespace.get(...))` to detect whether a macro

* Gets an attribute on a MathML node.

* Consume the specified number of arguments from the token stream, * and return the resulting array of arguments.

* Get a text or display version of this style.

* Set the current value of a name, and optionally set it globally too. * Local set() sets the current value and (when appropriate) adds an undo

* Asserts that the node is of the given type and returns it with stricter * typing. Throws if the node's type does not match.

* Asserts that the node is of the given type and returns it with stricter * typing. Throws if the node's type does not match.

* Given a pair of tokens (this and endToken), compute a `Token` encompassing * the whole input range enclosed by these two.

* Returns the topmost token on the stack, without expanding it. * Similar in behavior to TeX's `\futurelet`.

* Remove and return the next unexpanded token.

* Report nonstrict (non-LaTeX-compatible) input. * Can safely not be called if `this.strict` is false in JavaScript.

* Checks a result to make sure it has the right type, and throws an * appropriate error otherwise.

* Switches between "text" and "math" modes.

* Main parsing function, which parses an entire input.

* Like `this.havingSize(BASESIZE).havingStyle(style)`. If `style` is omitted, * changes to at least `\textstyle`.

* Return the CSS sizing classes required to switch from enclosing options * `oldOptions` to `this`. Returns an array of classes.

* Creates a new options object with the given math font or old text font. * @type {[type]}

* Returns the node more strictly typed iff it is of the given type. Otherwise, * returns null.

* Returns the node more strictly typed iff it is of the given type. Otherwise, * returns null.

* Start a new nested group, affecting future local `set`s.
