NAME

6       "LaTeXML::MathParser" - parses mathematics content
7

DESCRIPTION

9       "LaTeXML::MathParser" parses the mathematical content of a document.
10       It uses Parse::RecDescent and a grammar "MathGrammar".
11
12   Math Representation
13       Needs description.
14
15   Possibile Customizations
16       Needs description.
17
18   Convenience functions
19       The following functions are exported for convenience in writing the
20       grammar productions.
21
22       "$node = New($name,$content,%attributes);"
23           Creates a new "XMTok" node with given $name (a string or undef),
24           and $content (a string or undef) (but at least one of name or
25           content should be provided), and attributes.
26
27       "$node = Arg($node,$n);"
28           Returns the $n-th argument of an "XMApp" node; 0 is the operator
29           node.
30
31       "Annotate($node,%attributes);"
32           Add attributes to $node.
33
34       "$node = Apply($op,@args);"
35           Create a new "XMApp" node representing the application of the node
36           $op to the nodes @args.
37
38       "$node = ApplyDelimited($op,@stuff);"
39           Create a new "XMApp" node representing the application of the node
40           $op to the arguments found in @stuff.  @stuff are delimited
41           arguments in the sense that the leading and trailing nodes should
42           represent open and close delimiters and the arguments are separated
43           by punctuation nodes.
44
45       "$node = InterpretDelimited($op,@stuff);"
46           Similar to "ApplyDelimited", this interprets sequence of delimited,
47           punctuated items as being the application of $op to those items.
48
49       "$node = recApply(@ops,$arg);"
50           Given a sequence of operators and an argument, forms the nested
51           application "op(op(...(arg)))">.
52
53       "$node = InvisibleTimes;"
54           Creates an invisible times operator.
55
56       "$boole = isMatchingClose($open,$close);"
57           Checks whether $open and $close form a `normal' pair of delimiters,
58           or if either is ".".
59
60       "$node = Fence(@stuff);"
61           Given a delimited sequence of nodes, starting and ending with
62           open/close delimiters, and with intermediate nodes separated by
63           punctuation or such, attempt to guess what type of thing is
64           represented such as a set, absolute value, interval, and so on.
65
66           This would be a good candidate for customization!
67
68       "$node = NewFormulae(@stuff);"
69           Given a set of formulas, construct a "Formulae" application, if
70           there are more than one, else just return the first.
71
72       "$node = NewList(@stuff);"
73           Given a set of expressions, construct a "list" application, if
74           there are more than one, else just return the first.
75
76       "$node = LeftRec($arg1,@more);"
77           Given an expr followed by repeated (op expr), compose the left
78           recursive tree.  For example "a + b + c - d" would give "(- (+ a b
79           c) d)">
80
81       "MaybeFunction($token);"
82           Note the possible use of $token as a function, which may cause
83           incorrect parsing.  This is used to generate warning messages.
