#2739 — [ANN] python-ghostscript 0.6

I'm pleased to announce the new release vor python-ghostscript:


                 python-ghostscript 0.6

A Python-Interface to the Ghostscript C-API using ctypes

:License: GNU Public License v3 (GPLv3)

:Homepage: https://gitlab.com/pdftools/python-ghostscript
:Download: https://pypi.python.org/pypi/ghostscript

`Ghostscript`__, is a well known interpreter for the PostScript
language and for PDF. This package implements a interface to the
Ghostscript C-API using `ctypes`__. Both a low-level and a pythonic,
high-level interface are provided.

__ http://docs.python.org/library/ctypes.html

This package is currently tested only under GNU/Linux. Please report
whether it works in your environment, too. Thanks.


Latest Changes
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Please note: Version 0.5 has been skipped to avoid version conflicts
with the fork `python3-ghostscript`. All changes of that fork are
integrated into this release.

  * Add support for Python 3.x (tested with Python 3.4).
    Minimum required Python version is now 2.7.

  * Add support for display callback and an example program
    using it. Thanks to Lasse Fister.

  * Add context-interface (for the ``with``-statement).

  * ``GhostscriptError`` now has an attribute ``code`` holding
    the numeric error-code.

  * ``Ghostscript()`` now accepts keyword-arguments ``stdin``,
    ``stdout``, ``stderr`` for setting the respective stream. This was
    already implementd in version 0.4.1, but not documented.

  * Add unittest suite (using pytest).

  * Several bug fixes and smaller changes.

  * Switch version control to git and move project to gitlab. See
    Readme-file for the new URL.

  * Set up continuous integration tests.


Example
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Here is an example for how to use the high-level interface of
`python-ghostscript`. This implements a very basic ps2pdf-tool::

  import sys
  import ghostscript

  args = [
      "ps2pdf",    # actual value doesn't matter
      "-dNOPAUSE", "-dBATCH", "-dSAFER",
      "-sDEVICE=pdfwrite",
      "-sOutputFile=" + sys.argv[1],
      "-c", ".setpdfwrite",
      "-f",  sys.argv[2]
      ]

  ghostscript.Ghostscript(*args)
