LaTeXM...hParser(3pm)

💖 NAME 💖

Okay so this is the LaTeXM...hParser(3pm) page from User Contributed Perl Documentation, and the actual star of the show is "LaTeXML::MathParser" — parses mathematics content. Periodt. 💅✨

🌸 DESCRIPTION 🌸

"LaTeXML::MathParser" parses the mathematical content of a document. It uses Parse::RecDescent and a grammar "MathGrammar". No cap, that's the whole setup. 🧚‍♀️

✨ Math Representation ✨

Needs description. Literally, that's what it says, bestie. 🫶

🎀 Possibile Customizations 🎀

Needs description. And yes, the spelling stays exactly like that. 💅

🧚 Convenience functions 🧚

The following functions are exported for convenience in writing the grammar productions. Obsessed. 🫶

• $node = New($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. Sneaky lil 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.
