CONFIG_ops

manimlib/utils/config_ops.py 这个文件中主要实现了处理CONFIG字典和类的属性有关的函数

manimlib.utils.config_ops.get_all_descendent_classes(Class)

获取类 Class 的全部子类

manimlib.utils.config_ops.filtered_locals(caller_locals)

将 caller_locals 字典中去掉 self, kwargs 两个键值对

manimlib.utils.config_ops.digest_config(obj, kwargs, caller_locals={})

Sets init args and CONFIG values as local variables

The purpose of this function is to ensure that all configuration of any object is inheritable, able to be easily passed into instantiation, and is attached as an attribute of the object.

获取当前类和所有父类的 CONFIG 字典，转换为属性（优先级已经处理好）

  • 若要将当前所有局部变量也转化为属性，使用 digest_config(self, kwargs, locals())

manimlib.utils.config_ops.merge_dicts_recursively(*dicts)

Creates a dict whose keyset is the union of all the input dictionaries. The value for each key is based on the first dict in the list with that key.

dicts later in the list have higher priority

When values are dictionaries, it is applied recursively

递归合并字典
创建一个字典，其键集是所有输入字典的并集
在列表中位置越靠后的字典具有更高的优先级
当值为字典时，将递归应用
manimlib.utils.config_ops.soft_dict_update(d1, d2)

Adds key values pairs of d2 to d1 only when d1 doesn’t already have that key

合并字典，仅当 d1 没有该键时，才将 d2 的键值对添加到d1中

manimlib.utils.config_ops.digest_locals(obj, keys=None)

把当前局部变量设为属性
