Changes

develop

New Features

• Added a new documentation section describing rule application constraints: :ref:`rule-constraints`.

Bugs Fixed

• Fix adjacency constraint when in term mode and multiple labels in the constraint matches the same label in the candidate graph.
• Fix :cpp:func:`rule::Rule::makeInverse`/:py:meth:`Rule.makeInverse` to not crash when the rule has no external IDs recorded.

v0.15.0 (2024-01-26)

Incompatible Changes

• The graphs created by :cpp:func:`dg::Builder::addAbstract`/:py:meth:`DGBuilder.addAbstract` will no longer be empty, but have a single vertex with the label set to the identifier given in the description.
• Repeated calls to :cpp:func:`dg::Builder::addAbstract`/:py:meth:`DGBuilder.addAbstract` will no longer create subnetworks independently, but will act as if a single call was made with a concatenation of the inputs.
• CMake, change the option BUILD_TESTING_SANITIZERS to BUILD_WITH_SANITIZERS and default it to OFF. It did not cause libraries to be build with sanitizers as promised. Now it does, and is therefore not enabled by default.
• :cpp:func:`rule::Composer::eval`/:py:func:`RCEvaluator.eval` now by default prunes duplicate rules. The old behaviour can be obtained by setting the new parameter onlyUnique to false.

New Features

• Added support for LLDB in :option:`mod --debug`. It will be used if GDB is not available.

• Added :envvar:`MOD_DEBUGGER` to overwrite which debugger is invoked.

• Added :cpp:func:`graph::Graph::enumerateIsomorphisms`/:py:meth:`Graph.enumerateIsomorphisms`.

• Added :cpp:func:`graph::Union::printTermState`/:py:meth:`UnionGraph.printTermState`.

• Added verbosity argument for :cpp:func:`dg::DG::HyperEdge::print`/:py:meth:`DGHyperEdge.print` for printing debug information.

• Added printStereoWarnings flag to several loading functions:

  • :cpp:func:`graph::Graph::fromGMLString`/:py:meth:`Graph.fromGMLString`/:py:func:`graphGMLString`
  • :cpp:func:`graph::Graph::fromGMLStringMulti`/:py:meth:`Graph.fromGMLStringMulti`
  • :cpp:func:`graph::Graph::fromGMLFile`/:py:meth:`Graph.fromGMLFile`/:py:func:`graphGML`
  • :cpp:func:`graph::Graph::fromGMLFileMulti`/:py:meth:`Graph.fromGMLFileMulti`
  • :cpp:func:`graph::Graph::fromSMILES`/:py:meth:`Graph.fromSMILES`/:py:func:`smiles`
  • :cpp:func:`rule::Rule::fromGMLString`/:py:meth:`Rule.fromGMLString`/:py:func:`ruleGMLString`
  • :cpp:func:`rule::Rule::fromGMLFile`/:py:meth:`Rule.fromGMLFile`/:py:func:`ruleGML`

  If the input contains stereo-information, then the full stereo-information is inferred. This flag suppresses printing of warnings from this inferrence. Warnings from inferrence requested at a later time are not affected.

• Changed default graph isomorphism algorithm selection strategy. Before it always ran VF2, now it will use one of several algorithms, depending on the graphs and the label settings: 1) canonical SMILES string comparison, 2) comparison of canonical forms of the graphs, and 3) VF2.

• Added callback parameters for :cpp:func:`dg::DG::build`/:py:meth:`DG.build` to get notification when a new vertex or hyperedge is added to the derivation graph.

• Updated the "Quick Start" documentation for :ref:`compiling from source <compiling>`, to account for the need for virtual environments in newer versions of operating systems.

• Added instructions for :ref:`compiling in a Conda environment <compiling-conda>`.

• Added :cpp:class:`dg::VertexMapper`/:py:class:`DGVertexMapper` for enumerating vertex maps of derivations (atom maps for reeactions in a chemical setting).

Bugs Fixed

• Fix CMake finding proper Python version on macOS when multiple are installed.
• Fix :ref:mod-wrapper: such that it uses the Python executable that was found during CMake configuration. The environment variable :envvar:`MOD_PYTHON` can still be used to overwrite the Python executable.
• Fix :cpp:func:`post::enableCompileSummary`/:py:meth:`post.enableCompileSummary`, to emit the correct command, instead of acting like :cpp:func:`post::enableInvokeMake`/:py:meth:`post.enableInvokeMake`.
• Elaborate :ref:`quick-start` instructions for compiling to make it a bit easier to follow.
• Fix :cpp:func:`rule::CompositionMatch::composeAll`/:py:meth:`RCMatch.composeAll` when using terms and/or stereo information, to actually switch to those label settings.
• Allow term and stereo in :cpp:func:`graph::Graph::enumerateMonomorphisms`/:py:meth:`Graph.enumerateMonomorphisms`.
• Fix Graphviz instructions for Ubuntu in :ref:`quick-start`, to point at newer source archives instead an old one.
• #16, added pkg-config to Brewfile.
• In the post-processor, fall back to compiling commonPreamble.fmt each time, if creating a symbolic link fails. This may happen, e.g., in certain scenarios inside a Docker container.
• When using :cpp:func:`dg::Printer::pushVertexLabel`/:py:meth:`DGPrinter.pushVertexLabel` and :cpp:func:`dg::Printer::pushEdgeLabel`/:py:meth:`DGPrinter.pushEdgeLabel`, returning an empty string from the callback is now treated as if nothing should be shown from this callback, instead of showing an empty string and a seperator.
• mod.sty, fix how options are passed to xcolor.

v0.14.0 (2022-11-29)

Incompatible Changes

Doc, several pages have changed URL:

• libmod/libmod.html to libmod/index.html

• epim/epim.html to epim/index.html
• dataDesc/dataDesc.html to formats/index.html
• dgStrat/dgStrat.html to dgStrat/index.html
• As default, a Python package is now installed with pip which enables import of mod without extra PYTHONPATH manipulation. This may potentially clash with other packages of the same name. Use -DBUILD_PY_MOD_PIP=off for CMake to disable this (see :ref:`compiling`).
• Due to a change in escaping of # characters in DG vertex/hyperedge labels when printing, some custom labels with additional escaping may need adjustment. See also the bug fix entry regarding this.
• Bump Boost version required to 1.76 or higher to avoid an incompatibility with Python 3.10 (boostorg/python#344).

New Features

• Doc, a new section, :ref:`graph-model`, and restructuring of :ref:`formats`.
• The :ref:`GraphDFS format <format-graphDFS>` now supports disconnected graphs through .-edges, similar to :ref:`SMILES <graph-smiles>`. The graph loading functions :cpp:func:`graph::Graph::fromDFSMulti` and :py:func:`Graph.fromDFSMulti` has been added to load disconnected graphs.

• Added :cpp:func:`dg::Builder::addHyperEdge`/:py:meth:`DGBuilder.addHyperEdge`.
• Added :cpp:func:`graph::Printer::setRaiseIsotopes`/:cpp:func:`graph::Printer::getRaiseIsotopes`/:py:attr:`GraphPrinter.raiseIsotopes`. It was previously only available in the internal interface.
• Added :cpp:func:`graph::Printer::setWithGraphvizCoords`/:cpp:func:`graph::Printer::getWithGraphvizCoords`/:py:attr:`GraphPrinter.withGraphvizCoords`.
• Added :cpp:func:`graph::Printer::setGraphvizPrefix`/:cpp:func:`graph::Printer::getGraphvizPrefix`/:py:attr:`GraphPrinter.graphvizPrefix`.
• Whitespace is now allowed inside :ref:`format-dfs` strings.
• Make :option:`mod --memcheck` cause Valgrind to return non-zero on problems. Additionally add an atexit handler in Python to delete remaining global objects as this is not guaranteed otherwise.

• Added :cpp:func:`graph::Graph::enumerateMonomorphisms`/:py:meth:`Graph.enumerateMonomorphisms`.
• Added :cpp:func:`dg::Printer::setImageOverwrite`/:py:meth:`DGPrinter.setImageOverwrite`.
• Added :cpp:func:`dg::Builder::getDG`/:py:attr:`DGBuilder.dg` and :py:attr:`DGBuilder.isActive`.

• Fix :cpp:func:`graph::Graph::getGraphDFS`/:py:attr:`Graph.graphDFS` and :cpp:func:`graph::Graph::getGraphDFSWithIds`/:py:attr:`Graph.graphDFSWithIds` to not produce a :token:`~graphDFS:defRingId` directly followed by a :token:`~graphDFS:ringClosure` which is indistinguishable from just a :token:`~graphDFS:defRingId` when parsing the string again.
• Check for loop edges and parallel edges when loading graphs from DFS.
• :ref:`PostMØD <mod_post>`, avoid use of inline sed in compileTikz to make it work on macOS.
• For compiling from source on macOS, add cmake to Brewfile.
• Check for Boost.Python compiled against Python 3.10 through 3.20 as well.
• Py, use :py:class:`collections.abc.Iterable` instead of the deprecated/removed collections.Iterable.
• Py, use :py:func:`inspect.getfullargspec` instead of the deprecated/removed inspect.getargspec().
• mod_post scrub more unreproducible meta-info from figure PDFs.

• Fix handling of null pointers:
  • :cpp:func:`graph::Graph::isomorphism`/:py:meth:`Graph.isomorphism`.

Incompatible Changes

• dg::DG::abstract/dgAbstract has been removed. Use :cpp:func:`dg::Builder::addAbstract`/:py:func:`DGBuilder.addAbstract` instead. Added slightly better documentation as well, :ref:`dg_abstract-desc`.
• dg::DG::derivations has been removed. Use the repeated calls to :cpp:func:`dg::Builder::addDerivation` instead.
• dg::DG::ruleComp and dg::DG::calc() has been removed. Use the new :cpp:func:`dg::Builder::execute` instead.
• dgRuleComp and DG.calc has been deprecated, and their implementation is now based on :py:meth:`DGBuilder.execute`. Use :py:meth:`DGBuilder.execute` directly instead.
• The implementation of dgDerivations has changed and the function is now deprecated. Use repeated calls to :py:meth:`DGBuilder.addDerivation` instead.
• :cpp:func:`dg::Strategy::makeAdd` overloads, :py:meth:`DGStrat.makeAddStatic`, and :py:meth:`DGStrat.makeAddDynamic` now requires another argument of type :cpp:enum:`IsomorphismPolicy`/:py:class:`IsomorphismPolicy`.
• :ref:`strat-addSubset` and :ref:`strat-addUniverse` now accepts a new optional keyword argument graphPolicy of type :py:class:`IsomorphismPolicy`.
• dg::DG::list/DG.list has been removed, use :cpp:func:`dg::ExecuteResult::list`/:py:meth:`DGExecuteResult.list` instead.
• Information from strategies has been updated.

New Features

• Added new incremental build interface for :py:class:`DG`/:cpp:class:`dg::DG`. It includes:
  • :py:meth:`DG.__init__`/:cpp:func:`dg::DG::make` for constructing a derivation graph with this new interface.

  • :py:attr:`DG.locked`/:cpp:func:`dg::DG::isLocked`
• Added :py:class:`Derivations`/:cpp:class:`Derivations` as an alternative to :py:class:`Derivation`/:cpp:class:`Derivation` which contains a list of rules instead of at most a single rule. The latter is implicitly convertible to the former.

• Document and check proper preconditions on :cpp:class:`dg::DG`/:py:class:`DG`.
• Document and check precondition on :cpp:func:`dg::DG::HyperEdge::getInverse`/:py:attr:`DGHyperEdge.inverse`, that it is only avilable after the DG is locked.
• Properly throw an exception if :py:meth:`DGStrat.makeSequence`/:cpp:func:`dg::Strategy::makeSequence` if given an empty list of strategies.
• Properly implementing stringification of :py:class:`LabelType`/:cpp:enum:`LabelType`, :py:class:`LabelRelation`/:cpp:enum:`LabelRelation`, :py:class:`LabelSettings`/:cpp:class:`LabelSettings`, and :py:class:`IsomorphismPolicy`/:cpp:enum:`IsomorphismPolicy`.

• :cpp:func:`dg::DG::getGraphDatabase` now returns a :cpp:any:`std::vector` instead of a :cpp:any:`std::unordered_set`.
• Hide internal symbols in the library to increase optimization opportunities, and hide symbols in library dependencies. Libraries linking against libmod may stop linking, but configuration options has been added to disable symbol hiding.

New Features

• dgDump/dg::DG::dump should now be much, much faster in parsing the input file and loading the contained derivation graph.
• dgRuleComp/dg::DG::ruleComp should now be much faster during calculation.
• Added :py:func:`Graph.instantiateStereo`/:cpp:func:`graph::Graph::instantiateStereo`.
• Added :py:func:`rngReseed`/:cpp:func:`rngReseed`.

Bugs Fixed

• Fixed issues with auto in function signatures which is not yet in the C++ standard.

Other

• The functions :py:func:`prefixFilename`, :py:func:`pushFilePrefix`, and :py:func:`popFilePrefix` used by the :py:func:`include` function are now documented. A new class :py:class:`CWDPath` has been added.

v0.8.0 (2019-04-04)

Incompatible Changes

• Now requires v0.3 of GraphCanon (and PermGroup).
• graph::Graph::getMolarMass/Graph.molarMass has been removed.

• Removed dg::Strategy::GraphState::getHyperEdges/DGStratGraphState.hyperEdges. Use the graph interface of :cpp:any:`dg::DG`/:py:obj:`DG` instead.
• All atoms, including hydrogens, are now present with ids in strings from :cpp:any:`graph::Graph::getSmilesWithIds`/:py:obj:`Graph.smilesWithIds`.
• :cpp:any:`dg::DG::print`/:py:obj:`DG.print` now returns a pair of strings, instead of just one string. The first entry is the old return value. The second entry is the tex-file to depend on for layout coordinates.
• SMILES parsing: disallow isotope 0 as it is equivalent to not specifying an isotope.
• All classes in the Python interface without a custom hash function has their hash function removed. This is to prevent inconsistencies between hash and equality.

New Features

• Add :cpp:any:`graph::Graph::getGraphDFSWithIds`/:py:obj:`Graph.graphDFSWithIds` for getting a string annotated with the internal vertex ids in form of the class labels. This mirrors the previously added :cpp:any:`graph::Graph::getSmilesWithIds`/:py:obj:`Graph.smilesWithIds`.
• Improve error messages from GML parsing of lists.
• Changed the return type of :cpp:func:`dg::DG::getGraphDatabase` from a std::set to a std::unordered_set.

• Fix molecule decoding of atoms with negative charge and a radical.
• Fix dangling reference bug in first-order term handling.
• Fix inifiinite loop bug in first-order term handling.
• Remove extraneous template parameter lists to make it compile on GCC 8.
• Fix the documentation of :py:obj:`Graph.minExternalId`, :py:obj:`Graph.maxExternalId`, :py:obj:`Rule.minExternalId`, and :py:obj:`Rule.maxExternalId`. It was not being rendered.

v0.7.0 (2018-03-08)

Incompatible Changes

• Boost >= 1.64 is now required.
• Two new libraries, GraphCanon and PermGroup, are now required dependencies.
• Sphinx 1.7.1 is now required for building the documentation.
• :cpp:any:`dg::DG::HyperEdge::print`/:py:obj:`DGHyperEdge.print` now also takes an argument for colouring vertices/edges that are not matched by the rule. The default is now that matched vertices/edges are the default colour, while those that are not matched are grey.
• Most of the outer interface headers have now been moved to subfolders, and their content has been moved to corresponding namespaces. Several classes has been slightly renamed during the move, and some headers has been split into multiple header files.
• The previously deprecated class DerivationRef has now been removed along with DG.derivations in the Python interface.
• The previously deprecated method DG.vertexGraphs in the Python interface has been removed.

New Features

• Added functions to map external ids of graphs and rules to internal vertices.
• Added functions to get vertex coordinates for rules.
• :cpp:any:`dg::DG::print`/:py:obj:`DG.print` now returns the name of the PDF-file that will be created in post-processing.
• Add :cpp:any:`dg::Printer::setWithInlineGraphs`/:py:obj:`DGPrinter.withInlineGraphs` to input raw tex files for graphs in nodes instead of compiled PDFs. The generated tex code for the graphs is different to ensure unique Tikz node names.
• Add inline as a special argument for the graph Latex macros to input the raw tex file, instead of including a compiled PDF.
• Add :cpp:any:`graph::Graph::getSmilesWithIds`/:py:obj:`Graph.smilesWithIds` for getting a string annotated with the internal vertex ids in form of the class labels.
• The automorphism group of each graph is now available.

Experimental New Features

• Vertex/edge labels in graphs/rules can now be interpreted as first-order terms. Syntactic unification is then performed during morphism finding. See where :cpp:any:`LabelSettings`/:py:obj:`LabelSettings` is being used. Each rule has an optional :cpp:any:`LabelType`/:py:obj:`LabelType` to signify whether it was designed for use with :cpp:any:`LabelType::String`/:py:obj:`LabelType.String` or :cpp:any:`LabelType::Term`/:py:obj:`LabelType.Term`. Some algorithms will check this property for safety reasons, but the check can be disbled.
• There is now a prototype-implementation of http://doi.org/10.1007/978-3-319-61470-0_4, for adding stereo-information to graphs/rules. Use :cpp:any:`LabelSettings`/:py:obj:`LabelSettings` objects to enable it. See the paper for examples on how to use it. The full framework will be implemented and documented in a future version.

Bugs Fixed

• Multiple rules for the same derivation is now properly recorded.
• Fix documentation of :cpp:any:`rule::Rule::makeInverse`/:py:obj:`Rule.makeInverse`, it throws :cpp:any:`LogicError`/:py:obj:`LogicError` not :cpp:any:`InputError`/:py:obj:`InputError`.

• #2, throw exceptions from dg::DG::ruleComp/dgRuleComp and dg::DG::calc/DG.calc when isomorphic graphs are given.
• Throw more appropriate exception if :cpp:any:`dg::DG::print`/:py:obj:`DG.print` is called before dg::DG::calc/DG.calc.
• Various issues in graph/rule depiction related to positioning of hydrogens, charges, etc.
• Build system: give better error messages if a file is given where a path is expected.
• The produced SMILES strings are now truely canonical, as the new GraphCanon library is used.
• Fix :cpp:any:`AtomData`/:py:obj:`AtomData` to properly print radicals on uncharged atoms.
• Throw more friendly exceptions when loading graphs/rules that have loop/parallel edges.

Other

Incompatible Changes

• A C++14 compiler is now required (e.g., GCC 5.1 or later).
• The required Boost version is now either 1.59 or at least 1.61. Version 1.60 do not work due to boostorg/python#56.
• Make filenames in post-processing more Latex friendly.
• Rules specified in GML using constrainAdj must now enclose the operator in double quotes.
• DG: remove most of the interface related to DerivationRef. Use the graph interface instead. E.g.,
  • Deprecate DerivationRef. They now interconvert with :cpp:any:`dg::DG::HyperEdge`/:py:obj:`DGHyperEdge`.
  • Change DG::getDerivationRef into :cpp:any:`dg::DG::findEdge`/:py:obj:`DG.findEdge`.
  • Make DG.derivations return the edges instead in the Python interface. It is removed in the C++ interface. It will be removed from Python in the future.
  • Remove DG::inDerivations and DG::outDerivations.
  • Deprecate DG::vertexGraphs in Python, remove in C++.
• Move the graph interface for DG and Graph into separate headers: DGGraphInterface.h and GraphGraphInterface.h.
• Move GraphPrinter into a separate header.
• Move DGPrinter and DGPrintData into a separate header.
• All SBML features have been removed from the library.
• The deprecated DG::printMatrix function has been removed.
• dg::DG::calc/DG.calc will no longer print a message when it is done.
• :cpp:any:`dg::DG::print`/:py:obj:`DG.print` by default now only prints the hypergraph rendering. (For now, set Config::DG::printNonHyper to enable printing of the non-hypergraph rendering)
• :cpp:any:`graph::Graph::print`/:py:obj:`Graph.print` and :cpp:any:`rule::Rule::print`/:py:obj:`Rule.print` will now emit only one depiction when the two printers are equal.
• :cpp:any:`rule::Rule::print`/:py:obj:`Rule.print`, change the default colours used to indicate changes. Now different colours are used in L, K, R.
• :py:obj:`DGHyperEdge.print`, change the default match colour.
• Add < operator to vertices and edges of Graph, Rule, and DG.

New Features

• :cpp:any:`rule::Rule::makeInverse`/:py:obj:`Rule.makeInverse`.
• Reimplementation of GML parsing. It is now less strict with respect to ordering.
• Rule application constraint that checks the shortest path between two given vertices.
• Interactive mode for the wrapper script (option -i). It will use IPython as interpreter if it is available.
• The molecule model now includes radicals. The SMILES format has been extended to support radicals as well.
• Plugin infrastructure to load additional Python modules when using the wrapper script.
• Graph interface for rules: for a rule L \leftarrow K\rightarrow R, the three graphs can be accessed. The rule it self acts as the graph that is the pushout of the rule span.
• Graph loading: the ids used in GML and GraphDFS, as well as the class labels in SMILES can now be converted into vertices for the loaded graphs. If the class labels of a SMILES string are not unique, then none of them are available for querying.
• Add -v as alias for --version in the wrapper script.
• Add quite mode, -q, to the wrapper script.
• Add :cpp:any:`graph::Printer::setRotation`/:py:obj:`GraphPrinter.rotation`. Internally computed coordinates will be rotated by the set amount of degrees.

Bugs Fixed

• operator<< for Derivation: only try to print the rule if there is one.
• Properly throw an exception when graph GML parsing fails.
• Don't throw an exception while throwing an exception when graphs are disconnected.
• Fix bug in checking of certain constrainAdj during certain types of rule composition.
• Properly handle empty vertex/hyperedge ranges for DGs. Thanks to Robert Haas for reporting.
