15261ea65b* finish draft implementation * use @wrapss to remove docs problems * reduce complexity and add doc deprecation * Docs deprecated_params * add decoratos to __init__ * Add decorators to documentation * Finish detailed docs * Apply suggestions from code review Co-authored-by: Naveen M K <naveen@syrusdark.website> * change since/until/message param docs * Mark get_callable_info and deprecation_text_component as private * change how until is included in warning messages * Add The to parameter descriptions * make params docs more readable * make redirections docs clearer * update dependency list * order dependencies * update examples * fix dependency problem * fix duplicate problem * change decorator version * updated lock file * enhance function / method separation * fix typo and double underscores * rename message_ and replacement_ * Change warning to custom admonition * remove [] as default parameters * Remove "" around type * fix bug and move to inspect * doc string => docstring * rename to deprecate * change module docstring * change to deprecation.py * remove tests again * Rename decorators.py to deprecate.py * Update poetry.lock * Test if deprecated class outputs the correct warning when used * Rename deprecate to deprecation * Shorten conditional for msg, since, util * Specify decorator arguments in test * Add tests for since and until as arguments * Add test for msg argument for class * Add test for replacement argument for class * Remove unneeded docstring in deprecated class * Add test for deprecate method, no args * Update docstring examples, move deprecated method outside class * Add test for method in class, since and message args * Add test for deprecating nested class * Add test for deprecated method in nested class * Test deprecation of nested function * Test param deprecation, only params argument * Test deprecation of single method param * Rename single param test method name * Fix deprecated_params docstring whitespace * Test parameter redirection using tuple * Update warning msgs in deprecated_params docstring * Test parameter redirection using lambda function * Test param redirection from many to one * Test param redirection from one to many * Update Top.foo to deprecate with message * FadeIn & FadeOut overhaul and deprecations * Adjust examples * Add docs * Add simple example * handle empty docstrings * Update poetry.lock * Deprecate ShowCreation using decorator to test the docs * Test docstrings * add examples * Update example_scenes/basic.py Co-authored-by: Laith Bahodi <70682032+hydrobeam@users.noreply.github.com> Co-authored-by: Naveen M K <naveen@syrusdark.website> Co-authored-by: Ricky Chon <rickychon99@gmail.com> Co-authored-by: Laith Bahodi <70682032+hydrobeam@users.noreply.github.com>
