<66853113+pre-commit-ci[bot]@users.noreply.github.com> * feat(cli): optionally hide version splash (#3329) * feat(cli): optionally hide version splash As discussed in #3326, this PR proposes a new optional flag to hide the version splash when manim command in launched. Additionally, the splash print is now inly executed when the CLI is executed, not on module import. After looking at the current documentation, it does not seem to change anything. I only saw that you documented a version splash for when the CLI is used, but not when the module is imported. So removing it should not break the api docs. In the future, users can still have version information with `import manim; print(manim.__version__)`.

Ordinary lists do not have a "reshape" method. So we need to convert "sp1" and "sp2" to numpy arrays before calling the "insert_n_curves_to_point_list" function.

+Pull requests merged
+====================
+
+A total of 59 pull requests were merged for this release.
+
+Breaking changes
+----------------
+
+* :pr:`3020`: Rewrote Manim's color system
+   This change removed the ``colour`` library as a dependency
+   of Manim and replaced the internal handling of colors with
+   the newly added :class:`.ManimColor`. This also adds hundreds
+   of new predefined colors, see :mod:`.utils.color` for more
+   details.
+   This should only be a breaking change if you have interacted
+   directly with the ``colour`` module before. The general interface
+   has been kept stable.
+
+
+Highlights
+----------
+
+* :pr:`3299`: Added new ``manim checkhealth`` CLI subcommand
+   This adds a new command line interface subcommand which can be used to check
+   whether a local installation of Manim has been configured correctly, and all
+   required (and optional) dependencies are available. To try it, run it via
+   ``manim checkhealth`` or ``python -m manim checkhealth``.
+
+* :pr:`3427`: New feature: rendered examples in documentation can now be run directly via binder
+   This adds a "Make interactive" button below the examples in our documentation
+   that establishes a connection to binder such that examples can be modified and
+   rerendered directly from your browser.
+
+* :pr:`3086`: Introduced a new module :mod:`.typing` for type hints
+   This also adds various type hints to integral parts of the code base.
+
+* :pr:`3322`: Implemented auto-removal of auxiliary LaTeX files, enabled by default
+   This automatically removes auxiliary files creating during the compilation of
+   LaTeX documents like ``.aux`` or ``.dvi`` files. This behavior can be controlled
+   via the newly introduced ``no_latex_cleanup`` config key (``False`` by default).
+   On the command line, the autoremoval can be disabled via the ``--no_latex_cleanup``
+   CLI flag.
+
+* :pr:`3395`: Added support for Python 3.12
+
+New features
+------------
+
+* :pr:`3361`: Added three new rate functions
+    This adds the rate functions :func:`.smoothstep`, :func:`.smootherstep`,
+    :func:`.smoothererstep` based on the SmoothStep sigmoid functions.
+
+* :pr:`3264`: Added new mobjects :class:`.LabeledLine` and :class:`.LabeledArrow`
+
+
+Enhancements
+------------
+
+* :pr:`3190`: Made :class:`.CurvesAsSubmobjects` mobjects compatible with :meth:`.input_to_graph_point`
+
+
+* :pr:`3226`: Avoid using a mobject as a default argument of :class:`.ArcBrace`
+
+
+* :pr:`3366`: Added spacing between values and unit in :class:`.DecimalNumber`
+   This adds the new keyword argument ``unit_buff_per_font_unit`` (default: 0, for
+   backwards compatibility). Setting it to some positive number creates additional
+   space between the numeric value and the displayed unit.
+
+Fixed bugs
+----------
+
+* :pr:`3205`: Fixed type hint of ``angle`` in :class:`.Arc`
+
+
+* :pr:`3210`: Fixed :class:`.DecimalNumber` with ``show_ellipsis=True`` with the OpenGL renderer
+
+
+* :pr:`3211`: Fixed display issues with custom labels for :class:`.Axes` with the OpenGL renderer
+
+
+* :pr:`3298`: Fixed expand animation for :class:`.ManimBanner`
+
+
+* :pr:`3306`: Fixed IPython terminal history and embedded shell instantiation for scenes using :meth:`.Scene.interactive_embed`
+
+
+* :pr:`3315`: Fixed issue with parameter types in :meth:`.Scene.add_subcaption`
+
+
+* :pr:`3423`: Fixed incorrect submobject count of multi-part :class:`.Tex` mobjects
+   This resolves various issues where formulas were not displayed completely,
+   like it was the case with ``MathTex("1", "^{", "0")``.
+
+* :pr:`3284`: Fixed ``LinearTransformationSceneExample`` in Jupyter notebooks
+
+
+* :pr:`3302`: Fixed typo in comparison in :meth:`.OpenGLVMobject.interpolate`
+
+
+* :pr:`3340`: Fixed incorrect computation of bounding box for rotated :class:`.ImageMobject`
+
+
+* :pr:`3343`: Fixed return value of :meth:`.TexTemplate.add_to_preamble` and :meth:`.TexTemplate.add_to_document`
+
+
+* :pr:`3282`: Ensure that :meth:`.ArrowVectorField.get_vector` does not modify the passed inputs
+
+
+* :pr:`3392`: Fixed behavior of elongated tick lines for :class:`.NumberLine`
+
+
+* :pr:`3430`: Fixed CSV reader adding empty lists in rendering summary during documentation build
+
+
+* :pr:`3404`: Properly raise an exception on empty inputs to :class:`.AddTextLetterByLetter`
+
+
+Documentation-related changes
+-----------------------------
+
+* :pr:`3219`: Enabled social cards for links to documentation

+
+
+* :pr:`3251`: Add LaTeX installation instructions for Fedora
+
+
+* :pr:`3290`: Updated required dependencies for MacOS installations
+
+
+* :pr:`3325`: Added documentation for functions in :mod:`.mobject_update_utils`
+   This adds docstrings and typehints to :func:`.always_rotate`,
+   :func:`.always_shift`, :func:`.turn_animation_into_updater`
+
+* :pr:`3353`: Added documentation for :meth:`.Mobject.center`
+
+

+====================
+Adding Documentation
+====================
+
+Building the documentation
+--------------------------
+
+When you clone the Manim repository from GitHub, you can access the
+``docs/`` folder which contains the necessary files to build the
+documentation.
+
+To build the docs locally, open a CLI, enter the ``docs/`` folder with the
+``cd`` command and execute the following depending on your OS:
+
+-   Windows: ``./make.bat html``
+-   macOS and Linux: ``make html``
+
+The first time you build the docs, the process will take several
+minutes because it needs to generate all the ``.rst`` (reST:
+reStructured Text) files from scratch by reading and parsing all the
+Manim content. The process becomes much shorter the next time, as it
+rebuilds only the parts which have changed.
+
+
+Sphinx library and extensions
+-----------------------------
+
+Manim uses `Sphinx <https://www.sphinx-doc.org>`_ for building the
+docs. It also makes use of Sphinx extensions such as:
+
+-   `Autodoc: <https://www.sphinx-doc.org/en/master/usage/extensions/autodoc.html>`_
+    imports Manim's Python source code, extracts its docstrings and
+    generates documentation from them.
+-   `Autosummary: <https://www.sphinx-doc.org/en/master/usage/extensions/autosummary.html>`_
+    a complement to Autodoc which adds a special directive ``autosummary``,
+    used in Manim to automatically document classes, methods,
+    attributes, functions, module-level variables and exceptions.
+    Autosummary makes use of `Jinja templates <https://jinja.palletsprojects.com/templates/>`_,
+    which Manim defines for autosummarizing classes and modules
+    inside ``docs/source/_templates/``.
+-   `Graphviz extension for Sphinx: <https://www.sphinx-doc.org/en/master/usage/extensions/graphviz.html>`_
+    embeds graphs generated by the `Graphviz <https://graphviz.org/>`_
+    module, which must be installed in order to render the
+    inheritance diagrams in the :doc:`/reference`.
+-   `Napoleon: <https://www.sphinx-doc.org/en/master/usage/extensions/napoleon.html>`_
+    enables Sphinx to read Google style docstrings and, in
+    particular for Manim, `NumPy style docstrings <https://numpydoc.readthedocs.io/en/latest/format.html>`_
+    - see :doc:`docs/docstrings` for more information.
+
+
+Sphinx theme
+------------
+
+The theme used for this website is `Furo <https://sphinx-themes.org/sample-sites/furo/>`_.
+
+
+Custom Sphinx directives
+------------------------
+
+Manim implements **custom directives** for use with Autodoc and Autosummary, which
+are defined in :mod:`~.docbuild`:
+
+.. currentmodule:: manim.utils.docbuild
+
+.. autosummary::
+

+
+Adding type hints to functions and parameters
+---------------------------------------------
+
+Manim is currently in the process of adding type hints into the library. In this
+section, you will find information about the standards used and some general
+guidelines.
+
+If you've never used type hints before, this is a good place to get started:
+https://realpython.com/python-type-checking/#hello-types.
+
+Typing standards
+~~~~~~~~~~~~~~~~
+
+Manim uses `mypy`_ to type check its codebase. You will find a list of configuration values in the ``mypy.ini`` configuration file.
+To be able to use the newest typing features not available in the lowest
+supported Python version, make use of `typing_extensions`_.
+
+To be able to use the new Union syntax (``|``) and builtins subscripting, use
+the ``from __future__ import annotations`` import.
+
+.. _mypy: https://mypy-lang.org/
+.. _typing_extensions: https://pypi.org/project/typing-extensions/
+
+Typing guidelines
+~~~~~~~~~~~~~~~~~
+
+* Manim has a dedicated :mod:`~.typing` module where type aliases are provided.
+  Most of them may seem redundant, in particular the ones related to ``numpy``.
+  This is in anticipation of the support for shape type hinting
+  (`related issue <https://github.com/numpy/numpy/issues/16544>`_). Besides the
+  pending shape support, using the correct type aliases will help users understand
+  which shape should be used.
+
+* For typings of generic collections, check out `this <https://docs.python.org/3/library/collections.abc.html#collections-abstract-base-classes>`_
+  link.
+
+* Always use a type hint of ``None`` for functions that does not return
+  a value (this also applies to ``__init__``), e.g.:
+
+.. code:: py
+
+    def height(self, value) -> None:
+        self.scale_to_fit_height(value)
+
+* For variables representing paths, use the ``StrPath`` or ``StrOrBytesPath``
+  type alias defined in the :mod:`~.typing` module.
+
+* ``*args`` and ``**kwargs`` shouldn't be left untyped (in most cases you can
+  use ``Any``).
+
+* Following `PEP 484 <https://peps.python.org/pep-0484/#the-numeric-tower>`_,
+  use ``float`` instead of ``int | float``.
+
+* Use ``x | y`` instead of ``Union[x, y]``
+
+* Mobjects have the typehint ``Mobject``, e.g.:
+
+.. code:: py
+
+    def match_color(self, mobject: "Mobject"):
+        """Match the color with the color of another :class:`~.Mobject`."""
+        return self.set_color(mobject.get_color())
+
+* Always parametrize generics (``list[int]`` instead of ``list``,
+  ``type[Any]`` instead of ``type``, etc.). This also applies to callables.
+
+.. code:: py
+
+    rate_func: Callable[[float], float] = lambda t: smooth(1 - t)
+
+* Use ``TypeVar`` when you want to "link" type hints as being the same type.
+  Consider ``Mobject.copy``, which returns a new instance of the same class.
+  It would be type-hinted as:
+
+.. code:: py
+
+    T = TypeVar("T")
+
+
+    def copy(self: T) -> T: ...
+
+* Use ``typing.Iterable`` whenever the function works with *any* iterable, not a specific type.
+
+* Prefer ``numpy.typing.NDArray`` over ``numpy.ndarray``
+
+.. code:: py
+
+   import numpy as np
+
+   if TYPE_CHECKING:
+       import numpy.typing as npt
+
+
+   def foo() -> npt.NDArray[float]:
+       return np.array([1, 0, 1])
+
+* If a method returns ``self``, use ``typing_extensions.Self``.
+
+.. code:: py
+
+   if TYPE_CHECKING:
+       from typing_extensions import Self
+
+
+   class CustomMobject:
+       def set_color(self, color: ManimColor) -> Self:
+           ...
+           return self
+
+* If the function returns a container of a specific length each time, consider using ``tuple`` instead of ``list``.
+
+.. code:: py
+
+   def foo() -> tuple[float, float, float]:
+       return (0, 0, 0)
+
+* If a function works with a parameter as long as said parameter has a ``__getitem__``, ``__iter___`` and ``__len__`` method,
+  the typehint of the parameter should be ``collections.abc.Mapping``. If it also supports ``__setitem__`` and/or ``__delitem__``, it
+  should be marked as ``collections.abc.MutableMapping``.
+
+* Typehinting something as ``object`` means that only attributes available on every Python object should be accessed,
+  like ``__str__`` and so on. On the other hand, literally any attribute can be accessed on a variable with the ``Any`` typehint -
+  it's more freeing than the ``object`` typehint, and makes mypy stop typechecking the variable. Note that whenever possible,
+  try to keep typehints as specific as possible.
+
+* If objects are imported purely for type hint purposes, keep it under an ``if typing.TYPE_CHECKING`` guard, to prevent them from
+  being imported at runtime (helps library performance). Do not forget to use the ``from __future__ import annotations`` import to avoid having runtime ``NameError`` exceptions.
+
+.. code:: py
+
+   from typing import TYPE_CHECKING
+
+   if TYPE_CHECKING:
+       from manim.typing import Vector3D
+   # type stuff with Vector3D

-.. warning::
-   This section is still a work in progress.
-
-If you've never used type hints before, this is a good place to get started:
-https://realpython.com/python-type-checking/#hello-types.
-
-When adding type hints to manim, there are some guidelines that should be followed:
-
-* Coordinates have the typehint ``Sequence[float]``, e.g.
-
-.. code:: py
-
-    def set_points_as_corners(self, points: Sequence[float]) -> "VMobject":
-        """Given an array of points, set them as corner of the Vmobject."""
-
-* ``**kwargs`` has no typehint
-
-* Mobjects have the typehint "Mobject", e.g.
-
-.. code:: py
-
-    def match_color(self, mobject: "Mobject"):
-        """Match the color with the color of another :class:`~.Mobject`."""
-        return self.set_color(mobject.get_color())
-
-* Colors have the typehint ``Color``, e.g.
-
-.. code:: py
-
-    def set_color(self, color: Color = YELLOW_C, family: bool = True):
-        """Condition is function which takes in one arguments, (x, y, z)."""
-
-* As ``float`` and ``Union[int, float]`` are the same, use only ``float``
-
-* For numpy arrays use the typehint ``np.ndarray``
-
-* Functions that does not return a value should get the type hint ``None``. (This annotations help catch the kinds of subtle bugs where you are trying to use a meaningless return value. )
-
-.. code:: py
-
-    def height(self, value) -> None:
-        self.scale_to_fit_height(value)
-
-* Parameters that are None by default should get the type hint ``Optional``
-
-.. code:: py
-
-    def rotate(
-        self,
-        angle,
-        axis=OUT,
-        about_point: Optional[Sequence[float]] = None,
-        **kwargs,
-    ):
-        pass
-
-
-* The ``__init__()`` method always should have None as its return type.
-
-* Functions and lambda functions should get the typehint ``Callable``
-
-.. code:: py
-
-    rate_func: Callable[[float], float] = lambda t: smooth(1 - t)
-
-
-* Assuming that typical path objects are either Paths or strs, one can use the typehint ``typing.Union[str, pathlib.Path]``
-
-.. note::
-   As a helper for tool for typesets, you can use `typestring-parser
-   <https://github.com/Dominik1123/typestring-parser>`_
-   which can be accessed by first installing it via ``pip`` - ``pip install typestring-parser`` and
-   then using ``from typestring_parser import parse``.
-
-.. doctest::
-    :options: +SKIP
-
-    >>> from typestring_parser import parse
-    >>> parse("int")
-    <class 'int'>
-    >>> parse("int or str")
-    typing.Union[int, str]
-    >>> parse("list of str or str")
-    typing.Union[typing.List[str], str]
-    >>> parse("list of (int, str)")
-    typing.List[typing.Tuple[int, str]]

+``Transform`` vs ``ReplacementTransform``
+*****************************************
+The difference between ``Transform`` and ``ReplacementTransform`` is that ``Transform(mob1, mob2)`` transforms the points
+(as well as other attributes like color) of ``mob1`` into the points/attributes of ``mob2``.
+
+``ReplacementTransform(mob1, mob2)`` on the other hand literally replaces ``mob1`` on the scene with ``mob2``.
+
+The use of ``ReplacementTransform`` or ``Transform`` is mostly up to personal preference. They can be used to accomplish the same effect, as shown below.
+
+.. code-block:: python
+
+    class TwoTransforms(Scene):
+        def transform(self):
+            a = Circle()
+            b = Square()
+            c = Triangle()
+            self.play(Transform(a, b))
+            self.play(Transform(a, c))
+            self.play(FadeOut(a))
+
+        def replacement_transform(self):
+            a = Circle()
+            b = Square()
+            c = Triangle()
+            self.play(ReplacementTransform(a, b))
+            self.play(ReplacementTransform(b, c))
+            self.play(FadeOut(c))
+
+        def construct(self):
+            self.transform()
+            self.wait(0.5)  # wait for 0.5 seconds
+            self.replacement_transform()
+
+
+However, in some cases it is more beneficial to use ``Transform``, like when you are transforming several mobjects one after the other.
+The code below avoids having to keep a reference to the last mobject that was transformed.
+
+.. manim:: TransformCycle
+
+    class TransformCycle(Scene):
+        def construct(self):
+            a = Circle()
+            t1 = Square()
