LaTeXML::MathParser(3p)

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.
