@blink1073

5.3.0 (2021-11-15)

  • Update README.rst by @pooyaEst in [#181[(#181)
  • Added the option to specify temp_dir by @adityaapte in #192
  • Update CI by @blink1073 in #193
  • Update docs to fix build by @blink1073 in #194

5.2.0 (2020-08-05)

  • Add _get_max_nout and alternative nout mode using 'max_nout' (#170)

5.1.0 (2020-04-25)

  • FIX: no-OUT-args check was destroying original error location and was hiding similar user-errors (#161)

5.0.0 (2019-05-03)

- Removed the executable argument to Oct2Py in favor of using environment variables because we need to instantiate the octave convenience instance at startup.

4.3.0 (2019-05-02)

  • Add a plot_backend kwarg for eval and clean up default backend selection.

4.2.0 (2019-04-28)

  • Add support for Pandas DataFrames and Series (#125)
  • Remove unwanted octave-workspace files at exit (#133)

4.1.0 (2019-04-23)

  • Add a backend property to specify the graphics toolkit

4.0.5 (2017-04-08)

  • Fixed a thread safety bug when writing matlab files.

4.0.0 (2017-03-07)

Features

  • Added an feval method, which can be used to call Octave functions without creating a dynamic function. The function also supports calling a function by path.
  • The new feval method and the dynamic functions both now support a store_as argument, which saves the result of the call to the Octave workspace rather than returning it.
  • Added get_pointer method that can be used to retrieve a pointer to a value in the Octave namespace, including Octave functions. Pointers can be passed to feval or dynamic functions as function arguments. A pointer passed as a nested value will be passed by value instead.
  • Added an Oct2Py Cell ndarray subclass used for Octave cell arrays.
  • Added an Oct2PY StructArray numpy recarray subclass used for Octave structure arrays.
  • Added a stream_handler argument to eval and the new feval method that can be used to capture streaming output using a simple callback.

Breaking Changes

  • Removed inferred nout for Octave function calls; it must be explicitly given if not 1. The old behavior was too surprising and relied on internal logic of the CPython interpreter.
  • Any code that received Cell or Struct Array values will need to be updated.
  • Numpy booleans are now equivalent to Octave literals. They were previously handled as uint8 when sending to Octave.
  • Deprecated the use of keyword arguments to Octave function calls, use standard Octave calling conventions.
  • Deprecated the log and [return_both]{.title-ref} keyword arguments to eval(). See docs on Oct2Py.eval() for more information.
  • Oct2Py will no longer create dynamic functions for values that are not Octave functions - use [get_pointer]{.title-ref} or pull instead.

3.9.0 (2017-01-28)

  • Added support for Python 3.6 and Octave [input()]{.title-ref} functions.

3.8.0 (2016-12-25)

  • Added support for Octave class objects and clean up repr() and help() for dynamic Octave methods, (PR #104)

3.7.0 (2016-12-24)

  • Fixed error that caused the session to crash on Windows when Octave encountered a syntax error.
  • Added separate width and height specifiers to the [%%octave]{.title-ref} magic so the image can be constrained in one dimension while maintaining its aspect ratio.
  • Added an [extract_figures]{.title-ref} method to the [Oct2Py]{.title-ref} class which gives back a list of IPython Image or SVG objects for the created figures.
  • Completely rewrote the internal communication to Octave on top of the [octave_kernel]{.title-ref}, which enabled the Windows crash fix.
  • Removed the internal [_make_figs.m]{.title-ref} file, since that functionality is now in [octave_kernel]{.title-ref}.

3.6.1 (2016-11-20)

  • More plot creation cleanup - fault tolerance for svg files.

3.6.0 (2016-11-20)

  • Cleanup of plot creation - separate _make_figs.m file

3.5.0 (2016-01-23)

  • Disable --braindead Octave argument.

3.4.0 (2016-01-09)

  • Fixes for corner cases on structs

3.2.0 (2015-06-18)

  • Better handling of returned empty values
  • Allow OCTAVE environment variable

3.1.0 (2015-02-13)

  • Fix handling of temporary files for multiprocessing
  • Clean up handling of plot settings

3.0.0 (2015-01-10)

  • Add [convert_to_float]{.title-ref} property that is True by default.
  • Suppress output in dynamic function calls (using ';')

2.4.2 (2014-12-19)

  • Add support for Octave 3.8 on Windows

2.4.1 (2014-10-22)

  • Prevent zombie octave processes.

2.4.0 (2014-09-27)

  • Make [eval]{.title-ref} output match Octave session output. If verbose=True, print all Octave output. Return the last "ans" from Octave, if available. If you need the response, use [return_both]{.title-ref} to get the [(resp, ans)]{.title-ref} pair back
  • As a result of the previous, Syntax Errors in Octave code will now result in a closed session on Windows.
  • Fix sizing of plots when in inline mode.
  • Numerous corner case bug fixes.

2.3.0 (2014-09-14)

  • Allow library to install without meeting explicit dependencies
  • Fix handling of cell magic with inline comments.

2.2.0 (2014-09-14)

  • Fix IPython notebook support in Ubuntu 14.04
  • Fix toggling of inline plotting

2.1.0 (2014-08-23)

  • Allow keyword arguments in functions: [octave.plot([1,2,3], linewidth=2))]{.title-ref} These are translated to ("prop", value) arguments to the function.
  • Add option to show plotting gui with [-g]{.title-ref} flag in OctaveMagic.
  • Add ability to specify the Octave executable as a keyword argument to the Oct2Py object.
    • Add specifications for plot saving instead of displaying plots to [eval]{.title-ref} and dynamic functions.

2.0.0 (2014-08-14)

- Breaking changes

: -- Removed methods: [run]{.title-ref}, [call]{.title-ref}, [lookfor]{.title-ref} -- Renamed methods: [_eval]{.title-ref} -> [eval]{.title-ref}, [get]{.title-ref} -> [pull]{.title-ref}, [put]{.title-ref} -> [push]{.title-ref}, [close]{.title-ref} -> [exit]{.title-ref} -- Removed run and call in favor of using eval dynamic functions. -- Renamed methods to avoid overshadowing Octave builtins and for clarity. -- When a command results in "ans", the value of "ans" is returned instead of the printed string.
