LaTeXML...thParser(3)

💖 LaTeXML::MathParser 💖

bestie, welcome in — the manual name folded up here is User Contributed Perl Documentation, and this page is literally about LaTeXML::MathParser, no cap ✨

✨ NAME ✨

LaTeXML::MathParser — parses mathematics content 💅

🌸 DESCRIPTION 🌸

LaTeXML::MathParser parses the mathematical content of a document. It uses Parse::RecDescent and a grammar called MathGrammar. It’s giving parser main character energy fr fr 🧚

🧮 Math Representation 🧮

Official text check: Needs description. That’s what it says, bestie — I’m not gonna invent lore 🫶

💅 Possibile Customizations 💅

Also just: Needs description. (Yes, the heading has that spelling — iconic, keeping it 💀)

🎀 Convenience functions 🎀

The following functions are exported for convenience in writing the grammar productions. Here’s the whole roster, no skips, no cap 👑

• $node = New($name,$content,%attributes); — Creates a new XMTok node with the 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 a 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)))">. (Yes, that trailing > is exactly the flavor from the page 😭)
• $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)">. (Again with the little trailing > — preserving the exact mood 💅)
• MaybeFunction($token); — Note the possible use of $token as a function, which may cause incorrect parsing. This is used to generate warning messages.
