abjad> iotools.write_expr_to_ly_and_to_pdf_and_show(Note("c'8"), 'file_name_stem') # doctest: +SKIP
Write expr to temporary .ly and to PDF and then open the resulting PDF:
abjad> iotools.write_expr_to_ly_and_to_pdf_and_show(Note("c'8"), 'file_name_stem', write = False) # doctest: +SKIP
Return none.
The purpose of this function is to save named .ly and PDF output.
