NAME

"LaTeXML::MathParser" - parses mathematics content

DESCRIPTION

"LaTeXML::MathParser" parses the mathematical content of a document. It uses Parse::RecDescent and a grammar "MathGrammar". Math Representation Needs description. Possibile Customizations Needs description. Convenience functions The following functions are exported for convenience in writing the grammar productions. "$node = New($name,$content,%attributes);" Creates a new "XMTok" node with given $name (a string or undef), and $content (a string or undef) (but at least one of name or content should be provided), and attributes. "$node = Arg($node,$n);" Returns the $n-th argument of an "XMApp" node; 0 is the operator node. "Annotate($node,%attributes);" Add attributes to $node. "$node = Apply($op,@args);" Create a new "XMApp" node representing the application of the node $op to the nodes @args. "$node = ApplyDelimited($op,@stuff);" Create a new "XMApp" node representing the application of the node $op to the arguments found in @stuff. @stuff are delimited arguments in the sense that the leading and trailing nodes should represent open and close delimiters and the arguments are separated by punctuation nodes. "$node = InterpretDelimited($op,@stuff);" Similar to "ApplyDelimited", this interprets sequence of delimited, punctuated items as being the application of $op to those items. "$node = recApply(@ops,$arg);" Given a sequence of operators and an argument, forms the nested application "op(op(...(arg)))">. "$node = InvisibleTimes;" Creates an invisible times operator. "$boole = isMatchingClose($open,$close);" Checks whether $open and $close form a `normal' pair of delimiters, or if either is ".". "$node = Fence(@stuff);" Given a delimited sequence of nodes, starting and ending with open/close delimiters, and with intermediate nodes separated by punctuation or such, attempt to guess what type of thing is represented such as a set, absolute value, interval, and so on. This would be a good candidate for customization! "$node = NewFormulae(@stuff);" Given a set of formulas, construct a "Formulae" application, if there are more than one, else just return the first. "$node = NewList(@stuff);" Given a set of expressions, construct a "list" application, if there are more than one, else just return the first. "$node = LeftRec($arg1,@more);" Given an expr followed by repeated (op expr), compose the left recursive tree. For example "a + b + c - d" would give "(- (+ a b c) d)"> "MaybeFunction($token);" Note the possible use of $token as a function, which may cause incorrect parsing. This is used to generate warning messages.
