Changelog
=========
Version 0.10
------------
Add ``format`` argument to ``Graph/Digraph.render()``. This follows stand-alone
``render()`` function and mirrors the ``Graph/Digraph.pipe()`` method (usually,
``format`` is set on the instance).
Add ``renderer`` and ``formatter`` arguments to ``Graph/Digraph.render()`` and
``pipe()`` methods, as well as stand-alone ``render()`` and ``pipe()`` functions.
Version 0.9
-----------
Use ``sys.stderr`` to write stderr output from rendering process to stderr
(instead of file descriptor inhertiance). Ensures stderr is passed in special
enviroments such as IDLE.
Suppress rendering process stdout in ``render()``.
Make ``quiet=True`` also suppress ``stderr`` on success of ``render()`` and
``pipe()`` (exit-status ``0``).
Include ``stderr`` from rendering process in ``CalledProcessError`` exception.
Version 0.8.4
-------------
Tag Python 3.7 support (work around subprocess ``close_fds`` issue on Windows).
Version 0.8.3
-------------
Fix compatibility with ``python -OO``.
Version 0.8.2
-------------
Add ``nohtml()`` to support labels of the form ``'<...>'`` (disabling their default
treatment as HTML strings).
Make default ``'utf-8'`` ``encoding`` more visible.
Set ``encoding = locale.getpreferredencoding()`` when ``encoding`` argument/property is
set to ``None`` explicitly (follow stdlib ``io.open()`` behaviour).
Version 0.8.1
-------------
Add ``Source.from_file()``-classmethod (simpler in-line SVG display of ready-made
.gv files within Jupyter).
Drop Python 3.3 support.
Version 0.8
-----------
Add ``clear()``-method for ``Graph`` and ``Digraph``.
Add ``grapviz.version()`` function.
Drop dot source extra indent for edge statements following dotguide examples.
Include LICENSE file in wheel.
Version 0.7.1
-------------
Fix ``TypeError`` in ``graphviz.pipe()`` with invalid dot code under Python 3.
Add ``copy()``-method for ``Graph``, ``Digraph``, and ``Source``.
Add ``graphviz.render(..., quiet=True)``.
Fix ``graphivz.view()`` exception on unsupported platform.
Raise a dedicated ``RuntimeError`` subclass ``graphviz.ExecutableNotFound`` when the
Graphviz executables are not found.
Port tests from ``nose/unittest`` to ``pytest``, extend, use mocks.
Version 0.7
-----------
Support setting top-level attrs with ``g.attr(key=value)``.
Add context manager usage of ``subgraph()`` for adding a subgraph in a with-block.
Add json-based output formats to known ``FORMATS`` (Graphviz 2.40+).
Drop extra indent level for DOT source with nonempty ``graph/node/edge_attr``.
Add a final newline to a saved DOT source file if it does not end with one.
Raise ``subprocess.CalledProcessError`` on non-zero exit status from rendering.
Raise early when adding a ``subgraph()`` with ``strict=True`` (avoid DOT syntax error).
Make undocumented ``quote()``, ``quote_edge()``, and ``attributes()`` methods private.
Version 0.6
-----------
Drop Python 2.6 support (use ``graphviz<0.6`` there).
Improve tests for ``mkdirs()``.
Better document adding custom DOT using the ``body`` attribute.
Add ``view()``-support for FreeBSD (pull request Julien Gamba).
Version 0.5.2
-------------
Add ``ENGINES`` and ``FORMATS`` to the documented public API.
Version 0.5.1
-------------
Fixed PY3 compatibility.
Version 0.5
-----------
Add low-level functions ``render()``, ``pipe()``, and ``view()`` for directly working with
existing files and strings.
Support all ``render()``-arguments in the ``view()``-short-cut-method.
Version 0.4.10
--------------
Added ``'patchwork'`` engine.
Version 0.4.9
-------------
Add support for ``strict`` graphs and digraphs.
Hide ``render/pipe()`` subrocess console window on Windows when invoked from
non-console process (e.g. from IDLE).
Improve documentation markup/wording.
Make ``TestNoent`` more robust.
Version 0.4.8
-------------
Make ``_repr_svg_()`` available on ``Source`` (pull request RafalSkolasinski).
Version 0.4.7
-------------
Fixed ``view()``-method on Linux under Python 3 (pull request Antony Lee).
Version 0.4.6
-------------
Fixed ``view()``-method on Linux and Darwin (pull request Eric L. Frederich).
Version 0.4.5
-------------
Added example for HTML-like labels (``structs.py``).
Added ``Source`` class for rendering verbatim DOT source code.
Added Python 2.6 support (pull request Jim Crist).
Version 0.4.4
-------------
Added the ``pipe()``-method directly returning the ``stdout`` of rendering.
Added ``_repr_svg_()`` for inline rendering in IPython notebooks.
Version 0.4.3
-------------
Added examples generating some of the graphs from the Graphviz Gallery.
Added sphinx-based API documentation.
Version 0.4.2
-------------
Added support for HTML-like labels.
Version 0.4.1
-------------
Added support for less common output formats. Removed dropped formats (``'dia'``, ``'pcl'``).
Added ``'osage'`` layout engine.
Documented ``format`` and ``engine`` options in the README.
The ``view()`` convenience method now returns the result file name (like render()).
Version 0.4
-----------
Added ``attr()`` method for inline switching of node/edge attributes.
Added ``subgraph()`` method (obsoletes separate ``Subgraph`` class).
Add ``cleanup`` option to ``render()``.
Replaced ``dry`` option on ``render()`` with separate ``save()`` method.
Removed undocumented ``append()`` and ``extend()`` methods (if needed, the ``body``
attribute can be edited directly).
Version 0.3.5
-------------
Skip empty ``comment`` when creating DOT source.
Document ``graph_attr``, ``node_attr``, and ``edge_attr`` in the README.
More informative exception when Graphviz excutables cannot be called.
Version 0.3.4
-------------
Fixed missing identifier quoting for DOT keywords (thanks to Paulo Urio).
Version 0.3.3
-------------
Made ``format`` and ``engine`` case-insensitive.
Version 0.3.2

Fixed ``view()`` failing on paths with forward slashes on Windows.
