Release Notes

pydot/pydot (pydot)

v3.0.2

Compare Source

Added:

• All to_string() methods now accept an indent keyword argument, which can be
  either a number or a string. indentation=4 will indent each level of the
  output with four spaces. indentation=" " will indent each level by that many
  spaces. Other whitespace is also valid, e.g. indent="\t" for tab indents. (#​359)

Changed:

• Fixed quoting of identifiers with dots. (#​419)
• Fixed quoting of leading-numeral strings (strings starting with a number). (#​411)
• Fixed pickling/copying of Dot objects. (#​403)
• Improved handling of temporary files. Temporary files will be cleaned up in
  all cases, even when exceptions are raised or things exit unexpectedly. (#​394)
• From now on, the license files will be included in the distributed
  release as expected. (#​392)

v3.0.1

Compare Source

This is a bugfix release to correct a critical error introduced in 3.0.0.

Changed:

• Fix quoting in Edge.to_string(). (#​384)

v3.0.0

Compare Source

Removed:

• Breaking change: support for Python 3.7 dropped totally (#​371).
  It was already dropped, but now it's official.
• Breaking change (but for nobody): Invalid syntax removed (#​377).
  Removed syntax rules that were never implemented in graphviz's own parser.
• Attribute sorting removed (#​361).
  Pydot will preserve the original order of attributes as defined.
• Breaking change: Remove .create_attribute_methods() from classes (#​318).
  Setters and getters for attributes are now added to class definitions
  by calls to pydot.core.__generate_attribute_methods() immediately
  after the class is defined, for better compatibility with type-checking
  and introspection.

Changed:

• Internal storage and lookup of identifiers (names) improved (#​363).
  Pydot now always stores values as they were originally input, and only performs
  quoting on output.
  Previously, when a graph element was created with a name that contained a space
  or otherwise required quoting, the quotes would be added immediately, making it
  more difficult to retrieve the element using the .get_*() lookup methods.
  If a name requiring quotes was later set using .set_name(), no quotes would be
  added, causing the graph definition to become invalid.
  (Thanks to @​tusharsadhwani for initially pointing out the name-quoting issues.)
• Quoting for attribute values fixed (#​320).
  Attribute values containing comma-separated strings will now be quoted correctly.

Added:

• Keywords can now be used as names or attribute values (#​363).
  Graphviz keywords like "graph" or "subgraph" will now be properly quoted
  when used as attribute values or as names, where appropriate.
• Add standard Python logging, using the logger name pydot. For
  details, see the new section on Troubleshooting in README.md.

v2.0.0

Compare Source

Changed:

• Broken parsing caused by pyparsing updates fixed. (#​296)
  With this, the pydot project rises from the dead.

• (Internal) CI revived by @​ferdnyc. (#​302)
  Modernized and clarified the development process.
  Testing is done against multiple Python versions.

• Reorganized package/module structure. (#​230)
  The pydot package is installed as a directory now instead of as
  two modules:

  Before (pydot 0.x, 1.x)    After (pydot 2.x)
  
  site-packages/             site-packages/
  |-- pydot.py               `-- pydot/
  `-- dot_parser.py              |-- __init__.py
                                 |-- core.py
                                 |-- dot_parser.py
                                 `-- exceptions.py
  

  This is mostly an internal change that should go unnoticed by most
  users, especially those upgrading through pip or a software
  distribution. import pydot should work as it did before.
  Special cases:

  • import dot_parser no longer works. Change it to
    from pydot import dot_parser or see if you can use the wrappers
    pydot.graph_from_dot_data() or pydot.graph_from_dot_file().

    USER FEEDBACK REQUESTED
    We assume pydot users do not often directly import dot_parser.
    If you do, please report your reasons, so that we can consider
    making it available again before the final releashttps://github.com/pydot/pydot/issues/230m/Restructure package and module organization pydot/pydot#230

  • If you use pydot from a (cloned) pydot source tree:

    • The pydot source modules moved from the top directory to
      subdirectory src/pydot/.
    • When using a PYTHONPATH environment variable: Append /src,
      e.g. PYTHONPATH=~/Development/pydot/src. If you need to switch
      between pydot 1.x and pydot 2.x, add both, e.g.
      PYTHONPATH=~/Development/pydot/src:~/Development/pydot
    • When using an editable install (development mode): Re-run
      pip install -e . from the top directory of the source tree to
      update the links.

  • For users of the test suite:

    • The test suite no longer refuses to run from the top of the
      source tree.
    • This makes the test suite option --no-check redundant. It has
      no effect except for printing a deprecation warning. It will be
      removed in a future major release (pydot 3 or higher), then
      leading to an error.

• Reorganized exception hierarchy: (#​230)

  • New base class PydotException, derived from Python's Exception.
  • Pydot's Error exception class is now derived from PydotException
    instead of from Python's built-in Exception directly. Existing
    handlers should not be affected.
  • Exception class InvocationException was removed. It has not been
    raised by pydot since 2016 (v1.2.0).

• API (minor): Renamed the first parameter of the parser functions
  listed below from str to s. These functions primarily exist for
  internal use and would normally be called using positional arguments,
  so few users should be affected. (#​229)
  push_top_graph_stmt(s, loc, toks)
  push_graph_stmt(s, loc, toks)
  push_subgraph_stmt(s, loc, toks)
  push_default_stmt(s, loc, toks)
  push_attr_list(s, loc, toks)
  push_edge_stmt(s, loc, toks)

Deprecated:

• Test suite option --no-check. See "Reorganized package/module
  structure" above.

Removed:

• Drop support for Python 2 and Python < 3.7. (#​229, #​302, #​296).
  USER FEEDBACK REQUESTED
  ~~We are considering if pydot 2.0 should drop support for Python 3.5
  and 3.6 as well. If this would affect you, please leave a cohttps://github.com/pydot/pydot/issues/268ot/issues/268.~~
  EDIT: This was decided to be done, with a lot of time passed since this entry.
