Graphics.Rendering.MiniTypeset.Document

The document type, which expresses the intent of the user about what to render.

We support general layouting / formatting, and also construction specific to mathematical documents (similar to LaTeX).

TODO: fractions, brackets, mathemetical accents, compound symbols

The document data type

data Document ident

This data type describes what the user want to render.

The type parameter ident is used when the user want to know positions (bounding boxes) of different parts of the rendered text. It must have an Ord instance.

Constructors

Symbol !Char

a single character or symbol

String !String

a string

Space

a space character (do we need this to be separate?)

HorzCat !VAlign [Document ident]

horizontal concatenation

VertCat !HAlign [Document ident]

vertical concatenation

Overlay !(HAlign, VAlign) [Document ident]

overlaying on the top of each other

SubSupScript !(SubSup ident) !(Document ident)

add subscript and/or superscript

AboveBelow !(AboveBelow ident) !(Document ident)

above/below (like in a summation or limit)

WithColor !Col !(Document ident)

change color

WithStyle !BasicStyle !(Document ident)

change font family

Decorated !TextDecoration !(Document ident)

add text decoration

Identified !ident !(Document ident)

user identifier so that the layout engine can return position information

AddMargin !Margin !(Document ident)

an extra margin around the document

Realign !WhichQuad !(Document ident)

change the alignment box

EmptyDoc

the empty document
