v0.4.0

Polymake v0.4.0

Library updates

• Polymake.jl depends now on CxxWrap ^0.10.1
• Polymake.jl uses LoadFlint.jl and latest SingularBuilder

New features

• documentation strings of all polymake functions and methods was made
  available in julia
• handling of polynomials should be much smoother
• polymake banner is suppressed when imported in Oscar.jl

Fixed notable bugs

• libpolymake no longer requires GLIBCXX_3.4.26, i.e. Polymake.jl is
  compatible with libstdc++ shipped by julia, even when using very modern Linux
  systems (big thanks to Max Horn for investigating!)
• polymake doesn't grab all interrupts, so after using Polymake one can
  still Ctrl^C to interrupt julia. However...

Known Bugs:

• a Ctrl^C interrupt issued during computations in polymake may render
  involved objects into incomplete state which is leads to segfault at exit().
  We can not exclude silent data corruption in the process, so please DO NOT DO
  IT. We will be looking into a proper solution in the near future.

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.

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.
