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.
- 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)">
- Note the possible use of $token as a function, which may cause incorrect parsing. This is used to generate warning messages.
