Nodes allowed in math mode

Structs

Delimiter

Convenience struct for math delimiters, as constructed from a delimiter code

MathAtom

The most central kind of node in a math list. Consisting of a nucleus with optional superscript and subscript math lists.

MathChar

Convenience struct for characters in math mode

MathFontStyle

A resolved math font style. This is the state after the math list has been constructed. Has a definite style and font.

MathGroup

A resolved math group; the result of a math list.

MathStyle

One of the 8 styles of math formatting; The TeXBook calls these D,T,S,SS,D’,T’,S’ and SS’.

ResolvedChoice

A resolved \mathchoice node. This is the state after the math list has been constructed, at which point it is only a wrapper around a list of nodes.

UnresolvedMathChoice

A \mathcoice node, not yet resolved. When the current math list is closed, one of the four choices is picked, depending on the current style.

UnresolvedMathFontStyle

Unresolved math font style. This is the state while the math list is being constructed. Carries information about the family if relevant (or 0), to be picked when the math list is resolved.

Enums

EqNoPosition

The position of an eqno in a math list, i.e. \eqno (right) or \leqno (left).

MathClass

The 7 math classes

MathKernel

The kernel of a MathNucleus; the actual content of the nucleus.

MathNode

A math list node. Comes in two forms: an unresolved form, while the list is being constructed and the various font styles are not fixed yet (e.g. because an \atop comes later that shifts the font style), and a resolved form, where the fonts have been determined and are fixed. The parameter S:MathFontStyleT makes the distinction between the two forms. For S=MathFontStyle (the resolved form), this implements NodeTrait.

MathNodeList

An open list of unresolved math nodes. TODO: rethink this

MathNodeListType

Types of open math lists

MathNucleus

The nucleus of a MathAtom; a cohesive “unit” with optional sub/superscript.

MathStyleType

The four base math formatting styles

UnresolvedMarkers

Markers inserted by \displaystyle, \textstyle, \scriptstyle and \scriptscriptstyle. Only meaningful in unresolved mode, while the math list is open. When the list is closed, these are removed and used to determine the font style at that point.

Traits

MathChoiceT

This trait is implemented for exactly two types that indicate whether we are in the unresolved UnresolvedMathFontStyle or resolved (MathFontStyle) state.

MathFontStyleT

This trait is implemented for exactly two types that indicate whether we are in the unresolved UnresolvedMathFontStyle or resolved (MathFontStyle) state.
