[Unreleased]

[0.4.1] - 2021-07-11

Added

  • The legend in visualizer.py is back!

  • Documentation published to GitHub pages! It is contained in the docs/ folder.

  • setup.cfg now include links to the website.

Changed

  • Examples moved from pylinkage/examples/ to docs/examples/.

  • Tests moved from pylinkage/tests/ to tests/.

[0.4.0] - 2021-07-06

Added

  • The bounding_box method of geometry allow to compute the bounding box of a finite set of 2D points.

  • You can now customize colors of linkage’s bars with the COLOR_SWITCHER variable of visualizer.py.

  • movement_bounding_box in visualizer.py to get the bounding box of multiple loci.

  • parameters is optional in trials_and_errors_optimization (former exhaustive_optimization)

  • pylinkage/tests/test_optimizer.py for testing the optimizers, but it is a bit ugly as for now.

  • Flake8 validation in tox.ini

Fixed

  • set_num_constraints in Linkage was misbehaving due to update 0.3.0.

  • Cost history is no longer plotted automatically after a PSO.

Changed

  • exhaustive_optimization is now known as trials_and_errors_optimizattion.

  • Axis on linkage visualization are now named “x” and “y”, and no longer “Points abcsices” and “Ordinates”.

  • A default view of the linkage is displayed in plot_static_linkage.

  • Default padding in linkage representation was changed from an absolute value of 0.5 to a relative 20%.

  • Static view of linkage is now aligned with its kinematic one.

  • get_pos method of Linkage is now known as get_coords for consistency.

  • Parameters renamed, reorganized and removed in particle_swarm_optimization to align to PySwarms.

  • README.md updated consequently to the changes.

Removed

  • Legacy built-in Particle Swarm Optimization, to avoid confusions.

  • We do no longer show a default legend on static representation.

[0.3.0] - 2021-07-05

Added

  • Joint objects now have a get_constraints method, consistent with their set_constraints one.

  • Linkage now has a get_num_constraints method as synctactic sugar.

  • Code vulnerabilities checker

  • Walktrough example has been expanded and now seems to be complete.

Changed

  • Linkage’s method set_num_constraints behaviour changed! You should now add flat=False to come back to the previous behaviour.

  • pylinkage/examples/fourbar_linkage.py expanded and finished.

  • The begin parameter of article_swarm_optimization is no longer mandatory. linkage.get_num_constraints() will be used if begin is not provided.

  • More flexible package version in environment.yml

  • Output file name now is now formatted as “Kinematic {linkage.name}” in plot_kinematic_linkage function of pylinkage/visualizer.py

  • Python 3.6 is no longer tested in tox.ini. Python 3.9 is now tested.

Fixed

  • When linkage animation was saved, last frames were often missing inpylinkage/visualizer.py, function plot_kinematic_linkage.

[0.2.2] - 2021-06-22

Added

  • More continuous integrations workflows for multiple Python versions.

Fixed

  • README.md could not be seen in PyPi.

  • Various types

[0.2.1] - 2021-06-16

Added

  • swarm_tiled_repr function for pylinkage/visualizer.py, for vizualisation of PySwarms.

  • EXPERIMENTAL! hyperstaticity method Linkage’s hyperstaticity calculation.

Changed

  • pylinkage/exception.py now handles exceptions in another file.

  • Documentation improvements.

  • Python style improvements.

  • .gitignore now modifed from the standard GitHub gitignore example for Python.

Fixed

  • circle method of Pivot in pylinkage/linkage.py. was causing errors

  • tox.ini now fixed.
