v0.3.3

Polymake v0.3.3

Major bug fixed: due to empty default std::ostringstream constructor libpolymake.so was no longer compatible with the libstdc++ shipped with julia, which caused problems on linux distribution shipping newer versions of libstdc++. This has been fixed in #252.

Diff since v0.3.2

Closed issues:

• Error in printing of cones (#244)
• Julia 1.4 library compatibility problem on Linux. (#250)
• Polymake.jl doesn't work if user has too new C++ library (#251)

v0.3.0

Polymake v0.3.0

Library updates

• polymake binaries were updated to version 4.0r1 (released 19.02.2020)
• Polymake.jl depends now on CxxWrap ^0.9.0 (released 29.01.2020)
• polymake binaries link to SingularBuilder and FlintBuilder binaries.
• Polymake.jl supports julia versions: 1.0, 1.1, 1.2, 1.3 and 1.4.

Breaking changes

• constructors for big objects no longer support Pair{Symbol, Any} or Dict{Symbol, Any} arguments. The only supported syntax is through keyword arguments, i.e.

  polytope.Polytope(:POINTS => ...)

  needs to be replaced with

  polytope.Polytope(POINTS = ...)

Changes in exports

• internal (small) types are no longer exported in order to facilitate the use of Polymake.jl within Oscar project.
• Small types (the c++ wrapped structures) in Polymake.jl were renamed dropping the unfortunate pm_ prefix, so that:
  • pm_Matrix <: AbstractMatrix became Polymake.Matrix <: AbstractMatrix,
  • pm_Integer <: Base.Integer became Polymake.Integer <: Base.Integer, etc.
• internal modules of Polymake.jl have been renamed to lowercase (matching polymake application names), i.e. Polymake.Tropical became Polymake.tropical.
• those modules remain exported from Polymake.jl, i.e. upon using Polymake one can immediately call polytope.Cone(...).

To summarize: the only names exported from Polymake at the moment are: visual, application names and macros: @pm and @convert_to.

New features

• All BigObjects from polymake (i.e. Cones, Polytopes, Fans, etc) gained the corresponding constructors with doc-strings attached, i.e. polytope.Polytope is an actual struct with constructors producing an instance of BigObject. Asking for @doc polytope.Polytope will bring polymake helpstring.

• updated syntax for @pm macro. The rule of thumb is

  use @pm macro when julia throws UndefinedVariable error.

  Examples:

  • @pm polytope.Polytope(...) can be safely replaced by polytope.Polytope(...) (call to an actual constructor);
  • @pm polytope.Polytope{Rational}(...) can be safely replaced by polytope.Polytope{Rational}(...) (call to a parametrized constructor);
  • @pm polytope.Polytope{QuadraticExtension}(...) must use the macro, as QuadraticExtension is not a valid object in julia;

• @convert_to PerlType argument calls common::convert_to<PerlType> function to help with the conversion of Polymake.jl return types.

• New small types are wrapped and accessible from julia:

  • IncidenceMatrix <: AbstractMatrix
  • SparseMatrix <: SparseArrays.AbstractSparseMatrix
  • TropicalNumber <: Number
  • SparseVector <: SparseArrays.AbstractSparseVector
  • Polynomial (based on libsingular).

• All Polymake.jl array-style containers (except IncidenceMatrix, which stores only Bools) support the following element types:

  • Int64 (pm::Int, aka long)
  • Float64 (dobule)
  • Polymake.Integer (pm::Integer)
  • Polymake.Rational (pm::Rational)

Known Bugs:

• Nemo.jl MUST be loaded before Polymake.jl, see Nemo.jl/issues/108.
