Functions for converting between different representations of mathematical formulas.

Also note that in general writeLaTeX . readLaTeX /= id.

A typical use is to combine together a reader and writer.

import Control.Applicative ((<$>)) import Text.TeXMath (writeMathML, readTeX) texMathToMathML :: DisplayType -> String -> Either String Element texMathToMathML dt s = writeMathML dt <$> readTeX s

It is also possible to manipulate the AST using Generics. For example, if you wanted to replace all occurences of the identifier x in your expression, you do could do so with the following script.

import Control.Applicative ((<$>)) import Data.Generics (everywhere, mkT) import Text.TeXMath (writeMathML, readTeX) import Text.TeXMath.Types import Text.XML.Light (Element) changeIdent :: Exp -> Exp changeIdent (EIdentifier "x") = EIdentifier "y" changeIdent e = e texToMMLWithChangeIdent :: DisplayType -> String -> Either String Element texToMMLWithChangeIdent dt s = writeMathML dt . everywhere (mkT changeIdent) <$> readTeX s
