pyommlbuilder

A Python package that helps with building OMML tags for use in docx files.

For reference of OMML standards, please refer to P.3603-3723 of part 1 of ECMA-376, which defines the standards of Open Office XML, and can be downloaded here.

Example of quadratic equation:

from pyommlbuilder.main import Math, Fraction, Numerator, Denominator, SquareRoot, SuperscriptObject
import docx

expression = Math(
    "x=",
    Fraction(
        Numerator("-b±", SquareRoot([SuperscriptObject("b", "2"), "-4ac"])), 
        Denominator("2a"),
    ),
)


xml_element = expression._as_xml_element()

doc = docx.Document()
p = doc.add_paragraph()
p._element.append(xml_element)

doc.save("quadratic.docx")

Example of an equation block:

from pyommlbuilder.main import MathPara
from pyommlbuilder.helpers import make_aligned_equation
import docx

line1 = make_aligned_equation("x+3", "8")
line2 = make_aligned_equation("x", "8-3")
line3 = make_aligned_equation("", "5")

equation_block = MathPara(line1, line2, line3)

xml_element = equation_block._as_xml_element()

doc = docx.Document()
p = doc.add_paragraph()
p._element.append(xml_element)

doc.save("equation_block.docx")
