mathAdvanced

AGPL-3.0-onlyRelease 2L4

OMML — advanced math constructs (eqArr, groupChr, mathPr, borderBox, phantom).

Module mathAdvanced | Source packages/front/office/ooxml/src/extra/math-advanced.js | Deps xml | Worker-safe yes

Extends the core math module with the harder OMML elements: equation arrays, group characters, character boxes, phantoms, and the document-level <m:mathPr>.

Resolve

const ext = mathAdvanced.factory(xml);

parseMathElement (el) => {kind, value} dispatcher across every element this module + its val-only children handle
MATHPR_VAL string[] <m:mathPr>'s val-only child names
BB_FLAGS string[] <m:borderBoxPr>'s hide*/strike* flag names

Elements typed

eqArr, eqArrPr, maxDist, objDist, rSp, rSpRule, groupChr, groupChrPr, chr, vertJc, pos, borderBox, borderBoxPr, hideTop, hideBot, hideLeft, hideRight, strikeH, strikeV, strikeBLTR, strikeTLBR, box, boxPr, aln, diff, phant, phantPr, show, zeroAsc, zeroDesc, zeroWid, mathPr, mathFont, brkBin, brkBinSub, smallFrac, dispDef, lMargin, rMargin, defJc, preSp, postSp, interSp, intraSp, wrapIndent, wrapRight.

Notes

  • mathPr belongs to word/settings.xml — wire it via the wml-settings extension to surface it on result.settings.mathPr.
  • Equation arrays drop into m:eqArr rows that align around the = sign by default.
