14. Changes

14.1. develop

14.1.1. Incompatible Changes

Doc, several pages have changed URL:

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

• pymod/pymod.html to pymod/index.html

• postmod/postmod.html to postmod/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 Compiling from Source).

14.1.2. New Features

• Doc, a new section, Graph, Rule, and Molecule Model, and restructuring of Data Formats.

The previous style is removed in libMØD and deprecated in PyMØD.

• dg::DG::HyperEdge::print()/DGHyperEdge.print() now throws exceptions if either no rules are associated with the hyperedge or if at least one of the associated rules does not lead to a derivation.

• dg::PrintData/DGPrintData, many interface changes, including proper argument checking.

• Now requires v0.4 of GraphCanon (and PermGroup).

• dg::DG::getGraphDatabase() now returns a std::vector instead of a 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.

• dg::DG::print()/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.

14.7.2. New Features

• Added support for isotopes (see Molecule Encoding).

• Added graph::Graph::getExactMass()/Graph.exactMass.

  • rule::Rule::RightGraph::Vertex/Rule.RightGraph.Vertex, rule::Rule::RightGraph::Edge/Rule.RightGraph.Edge

  • dg::DG::Vertex/DGVertex, dg::DG::HyperEdge/DGHyperEdge

• The vertices of all graph interfaces now have a proper hash support.

• Added dg::Printer::setRotationOverwrite()/DGPrinter.setRotationOverwrite() and dg::Printer::setMirrorOverwrite()/DGPrinter.setMirrorOverwrite().

• Document inputGraphs and inputRules.

14.7.4. Other

• Now compiles with -fno-stack-protector (some OS distributions messes with default flags).

• The Makefile from mod --get-latex now cleans .vrb, .snm, and .nav files as well.

14.8. v0.7.0 (2018-03-08)

14.8.1. 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.

• dg::DG::HyperEdge::print()/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.

14.8.2. New Features

• Add graph::Graph::getSmilesWithIds()/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.

14.8.3. 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 LabelSettings/LabelSettings is being used. Each rule has an optional LabelType/LabelType to signify whether it was designed for use with LabelType::String/LabelType.String or LabelType::Term/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 LabelSettings/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.

14.8.4. Bugs Fixed

• Multiple rules for the same derivation is now properly recorded.

• Fix documentation of rule::Rule::makeInverse()/Rule.makeInverse, it throws LogicError/LogicError not InputError/InputError.

• Set the name of a rule from rule::Rule::makeInverse()/Rule.makeInverse to something more descriptive.

• Fix graph/rule depiction bug with non-zero rotation.

• Fix DG dump loading to also load derivations with no rules.

• Don’t crash when trying dg::DG::findVertex()/DG.findVertex with a graph not in the derivation graph.

• Don’t crash when trying to print derivations with multiple rules.

• Throw more appropriate exception if dg::DG::print()/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 AtomData/AtomData to properly print radicals on uncharged atoms.

• Throw more friendly exceptions when loading graphs/rules that have loop/parallel edges.

14.8.5. Other

• The documentation now has a “Known Issues” section, describing an issue where post-processing may fail if pdflatex has been upgraded after installation

14.9. v0.6.0 (2016-12-22)

14.9.1. 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 https://github.com/boostorg/python/issues/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 dg::DG::HyperEdge/DGHyperEdge.

  • Change DG::getDerivationRef into dg::DG::findEdge()/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.

• dg::DG::print()/DG.print by default now only prints the hypergraph rendering. (For now, set Config::DG::printNonHyper to enable printing of the non-hypergraph rendering)

• graph::Graph::print()/Graph.print and rule::Rule::print()/Rule.print will now emit only one depiction when the two printers are equal.

• rule::Rule::print()/Rule.print, change the default colours used to indicate changes. Now different colours are used in L, K, R.

• DGHyperEdge.print, change the default match colour.

• Add < operator to vertices and edges of Graph, Rule, and DG.

14.9.2. New Features

• rule::Rule::makeInverse()/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 graph::Printer::setRotation()/GraphPrinter.rotation. Internally computed coordinates will be rotated by the set amount of degrees.

14.9.3. 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.

14.10. v0.5.0 (2016-03-07)
