Module mathml 

MathML conversion processor.

Port of LaTeXML::Post::MathML (2162 lines) + submodules:

• Presentation.pm (146 lines) — Presentation MathML rendering rules
• Content.pm (31 lines) — Content MathML rendering rules
• Linebreaker.pm (1053 lines) — MathML line-breaking algorithm
• OperatorDictionary.pm (252 lines) — Operator symbol table

This is the primary math conversion format for web output. Converts XMath parsed math into Presentation MathML and/or Content MathML.

Modules

content

Content MathML rendering rules.

linebreaker

MathML line-breaking algorithm.

operator_dictionary

MathML Operator Dictionary.

presentation

Presentation MathML rendering rules.

Structs

MathML

MathML post-processor.

TextAttrs

Perl’s %attr for pmml_text_aux — the presentation attributes an enclosing ltx:* element contributes to the m:mtext elements below it.

Enums

ApplyHandler

Presentation handler type for XMApp nodes.

Functions

apply_handler_for_meaning

Determine the presentation handler for a specific meaning.

apply_handler_for_role

Determine the presentation handler for an XMApp based on operator role.

cmml_element_for_meaning

Known Content MathML elements for specific meanings.

convert_xm_text_content

Eagerly materialize an XMText-or-picture subtree into owned NodeData.

encoding_for_mimetype

MathML encoding names for parallel markup annotation-xml.

find_inherited_attribute

Find an inherited attribute by walking up the LaTeXML ancestor chain.

get_xm_hint_spacing

Convert an XMHint spacing attribute to em value.

has_dedicated_cmml_structure

Whether an XMApp with this meaning has a dedicated Content MathML structure.

is_bigop_role

Whether a role should use the “big operator” presentation style.

pmml_parenthesize

Parenthesize an expression with open/close delimiters.

pmml_punctuate

Punctuate a list of items with separators.

pmml_row

Wrap items in an mrow, filtering out ignorable items.

pmml_tag_for_role

Presentation MathML tag for a token role.

pmml_text_aux

Convert a text node within XMText to Presentation MathML.

pmml_unrow

Unwrap an mrow if it has no attributes.

rebuild_text_subtree

Rebuild a libxml2 subtree into owned NodeData, dropping internal _*, xml:id, and fragid attributes. Shared between convert_xm_text_content (Perl convertXMTextContent, Post.pm L456-489) and pmml_text_aux for cases where Perl calls cloneNode($node, 'nest') (MathML.pm L1073) — i.e. when an unhandled element like ltx:ref appears inside a text-mode fragment and must survive into the output so the XSLT can transform it (e.g. ltx:ref → <a>).

rebuild_text_subtree_with_doc

Same as rebuild_text_subtree, but consults the post-document’s namespace map to resolve elements whose source xmlns="…" carries an empty prefix. add_nodes only emits elements whose tag is prefix:local; without a prefix the element is dropped with a malformed:namespace warning. libxml2 reports an empty Namespace::get_prefix() for the default-namespace branch even when the doc has a ltx: prefix declared elsewhere, so we reverse-lookup the URI in PostDocument::namespaces to recover the canonical prefix.

style_size

Size percentage for math styles.

style_step

Math style step-down table.
