new Context()private

This class contains the rendering context of the current parse level.

It also holds information about the parent context to handle scaling adjustments.

When a new scope is entered, a clone of the context is created with .clone() so that any further changes remain local to the scope.

A scope is defined for example by:

  • an explicit group enclosed in braces {...}
  • a semi-simple group enclosed in \bgroup...\endgroup
  • an environment delimited by \begin{<envname>}...\end{<envname>}
mathstyle : string

'text' (aka 'inline'), 'display', 'script' or 'scriptscript'

opacity : number
size : number
generateID : boolean | object

If true, unique IDs should be generated for each span so they can be mapped back to an atom. Can also be an object with a seed field to generate a specific range of IDs. Optionally, if a groupNumbers property is set to true, an additional span will enclose strings of digits. This is used by read aloud to properly pronounce (and highlight) numbers in expressions.

parentMathstyle : string
parentSize : number
macros : object

A macros dictionary
