Release Notes

0.9.13 (2023-05-14)

  • Conversion to wrapper types PyList, PySet, PyDict or PyIterable now default to having element type Any instead of Py.
  • The __repr__ method of wrapped Julia objects now uses the 3-arg show method for nicer (richer and truncated) display at the Python REPL.
  • The IPython extension can now be loaded as just %load_ext juliacall.
  • The %%julia IPython magic can now synchronise variables between Python and Julia.
  • Bug fixes.

0.9.12 (2023-02-28)

  • Bug fixes.

0.9.11 (2023-02-15)

  • In PyArray{T}(x), the eltype T no longer needs to exactly match the stored data type. If x has numeric elements, then any number type T is allowed. If x has string elements, then any string type T is allowed.
  • StaticString (the inline string type used by PyArray) supports the AbstractString interface better.

0.9.10 (2022-12-02)

  • Bug fixes.

0.9.9 (2022-10-20)

  • Bug fixes.

0.9.8 (2022-10-18)

  • Adds line_buffering option to PyIO.
  • Improvements to stdout when using juliacall.ipython including line-buffering.

0.9.7 (2022-10-11)

  • If CondaPkg is using the Null backend, PythonCall will now use python from the PATH.
  • Bug fixes.

0.9.6 (2022-09-09)

  • When using JuliaCall from an interactive Python session, Julia is put into interactive mode: isinteractive() is true, InteractiveUtils is loaded, and a nicer display is used.
  • Wrapped Julia values now truncate their output when displayed via _repr_mimebundle_.
  • Numpy arrays with structured dtypes can now be converted to PyArray, provided the fields are aligned.
  • Python named tuples can be converted to Julia named tuples.
  • Bug fixes.

0.9.5 (2022-08-19)

  • Adds PythonCall.GC.disable() and PythonCall.GC.enable().
  • Experimental new function juliacall.interactive() allows the Julia async event loop to run in the background of the Python REPL.
  • Experimental new IPython extension juliacall.ipython providing the %julia and %%julia magics for executing Julia code.
  • Experimental new module juliacall.importer allowing you to write Python modules in Julia.
  • Bug fixes.

0.9.4 (2022-07-26)

  • Bug fixes.

0.9.3 (2022-07-02)

  • Bug fixes.

0.9.2 (2022-07-02)

  • Many Julia CLI options (such sysimage or number of threads) can be set from JuliaCall.
  • Bug fixes.

0.9.1 (2022-06-18)

  • PyArray can be constructed using the __array_struct__ part of the Numpy array interface. Constructing PyArray(x) is now about 50x faster, or 175x faster if you fully specify the type.
  • JuliaCall can now be imported on Apple M1.

0.9.0 (2022-05-27)

  • Breaking. Removes getpy: you may now overload Py directly, which now need not always return a new object (e.g. for singletons or wrappers).
  • Breaking. Conversion rules no longer take a new object every time.
  • Breaking. Improved Tables-interface support for PyPandasDataFrame: better inferred column types; better handling of non-string column names; columns are usually wrappers (PyArray or PyList). Constructor arguments have changed. Dict methods have been removed (basically only the Tables interface is supported).
  • Breaking. A Py which is convertible to PyTable is no longer considered to be a table itself; you must convert explicitly.
  • Adds pyhasitem and 3-arg pygetitem.
  • Extends Base.get, Base.get!, Base.haskey and 2-arg Base.hash for Py.
  • PyArray can now have any element type when the underlying array is of Python objects.
  • Adds ArrayValue.to_numpy().
  • Bug fixes.

v0.8.0 (2022-03-17)

  • Breaking: Removes pymethod and pyclass. In the future, pyclass may become sugar for types.new_class (namely you can specify a metaclass).
  • Adds pyfunc, pyclassmethod, pystaticmethod and pyproperty.
  • pyconvert_add_rule is now documented. Its semantics have changed, including the separator of the first argument from / to :.
  • A pandas <NA> value is now converted to missing.
  • A NaN in a PyPandasDataFrame is converted to missing.
  • Breaking: Removes using and As from JuliaCall.
  • Adds convert to JuliaCall (replacing As).
  • Bug fixes.

v0.6.1 (2022-02-21)

  • Conversions from simple ctypes types, e.g. ctypes.c_float to Cfloat.
  • Conversions from simple numpy types, e.g. numpy.float32 to Float32.
  • Bug fixes.

v0.6.0 (2022-02-17)

  • Breaking: JuliaCall now uses JuliaPkg to manage Julia dependencies.
  • Bug fixes.

v0.5.1 (2022-01-24)

  • Bug fixes.

v0.5.0 (2021-12-11)

  • Breaking: PythonCall now uses CondaPkg to manage Python dependencies.
  • Python objects can be shared with PyCall provided it uses the same interpreter, using methods PythonCall.Py(::PyCall.PyObject) and PyCall.PyObject(::PythonCall.Py).
  • Adds PythonDisplay which displays objects by printing to Python's sys.stdout. Used automatically in IPython in addition to IPythonDisplay.
  • Removes the GLOBAL mode from @pyexec. Use global in the code instead.
  • Bug fixes.
