from borb.pdf.canvas.layout.hyphenation.hyphenation import Hyphenation
from borb.pdf import Alignment
from borb.pdf import Paragraph
from borb.pdf import PDF
from borb.pdf.canvas.geometry.rectangle import Rectangle
from borb.pdf import HexColor
from borb.pdf.canvas.layout.annotation.square_annotation import SquareAnnotation

from decimal import Decimal

# create Document
doc: Document = Document()

# create Page
page: Page = Page()
# add Page to Document
doc.add_page(page)

r: Rectangle = Rectangle(
    Decimal(30),                # x: 0 + page_margin
    Decimal(742),    # y: page_height - page_margin - height_of_textbox
    Decimal(50),      # width: page_width - 2 * page_margin
    Decimal(70),               # height
)

page.add_annotation(SquareAnnotation(
    r,
    stroke_color=HexColor("#ff0000"),
)
                    )

Paragraph("Alignement",
          horizontal_alignment=Alignment.CENTERED,
          vertical_alignment=Alignment.MIDDLE,
          text_alignment=Alignment.CENTERED,
          hyphenation=Hyphenation("en-us")
          ).paint(page, r)

# store
with open("output.pdf", "wb") as pdf_file_handle:
    PDF.dumps(pdf_file_handle, doc)

cause this error:

if len(lines_of_text[-1]) > 0 and not self._respect_spaces_in_text:
IndexError: list index out of range

Expected behaviour The first word of parapraph needs to be split without error.

Modify https://github.com/jorisschellekens/borb/blob/9ac59b6f8bae6c8e3ba296e2aa91122d4792bcfd/borb/pdf/canvas/layout/text/paragraph.py#L144 to lines_of_text = [""] seems to fix the problem
