# io.pdf

`abjad.tools.io.` `pdf`(target=-1)

  Call `pdf( )` to open PDF output files generated by Abjad.

      abjad> t = Note(0, (1, 4))
      abjad> show(t)

  The input above renders a PDF output file and opens it.

  If you close the PDF output file and want to open it again, call `pdf( )`.

      abjad> pdf( )

  Use `pdf( )` to open the last PDF output file after it has been closed.

  - When `target = -1` open the last PDF output file.
  - When `target = -2` open the next-to-last PDF output file.
  - When `target = -3` open the next-to-next-to-last PDF output file.
  - When `target` is positive open `target.pdf`.

  Note

  By default, Abjad writes LilyPond input files to the `~/.abjad/output` directory. You may change this by setting the `abjad_output` variable in the `config.py` file.
