    Class MathEquationArray

    An equation array (m:eqArr): rows of math, one to a line, lined up at the points between their parts, as LaTeX's align and aligned, with an equation number at the end of any row.

    Word marks the points with an &, and the number with a #, in the text. So an & or a # in a MathRun in the array is taken as one too. LibreOffice shows the & and #, and centres the rows; Pages lines them up, but shows the #.

    new MathEquationArray({
      rows: [
        { parts: [[new MathRun("y")], [new MathRun("=mx+b")]], equationNumber: "(1)" },
        { parts: [[new MathRun("y′")], [new MathRun("=m")]], equationNumber: "(2)" },
      ],
    });

    • get writtenAs(): readonly BaseXmlComponent[] | undefined
      Internal

      The components written in this one's place, one after another, when it can't be written as a single element, such as a run with another run in its children. Undefined when it is written as itself.

      Returns readonly BaseXmlComponent[] | undefined

    • Prepares this component and its children for XML serialization.

      This method is called by the Formatter to convert the component tree into an object structure compatible with the xml library (https://www.npmjs.com/package/xml). It recursively processes all children and handles special cases like attribute-only elements and empty elements.

      The method can be overridden by subclasses to customize XML representation or execute side effects during serialization (e.g., creating relationships).

      Parameters

      • context: IContext

        The serialization context containing document state

      Returns IXmlableObject | undefined

      The XML-serializable object, or undefined to exclude from output

      // Override to add custom serialization logic
      prepForXml(context: IContext): IXmlableObject | undefined {
        // Custom logic here
        return super.prepForXml(context);
      }
