Is there a way to tostring() a Document?

[bjuan210302]

With an existing vpype.Document is there a way to output its raw SVG as string? I know there's write_svg that takes a document, but I'm working from a serverless and can't access a file system.

I there any way of achieving this? The only thing I can think of is straight up copying the write_svg and returning dwg.tostring() instead of wirting it to a file.

write_svg takes a TextIO as argument. So you can pass a StringIO(docs):

import io
import vpype as vp

string_io = io.StringIO()
doc = vp.Document()
vp.write_svg(string_io, doc)
print(string_io.getvalue())
