feat(HTML)!: `HTML` class no longer inherits from `str` #86

schloerke · 2024-04-22T21:21:51Z

Breaking changes

HTML no longer inherits from str. It now inherits from collections.UserString. This was done to avoid confusion between str and HTML objects. (feat(HTML)!: HTML class no longer inherits from str #86)
Tag and TagList's method .get_html_string() now both return str instead of HTML. (feat(HTML)!: HTML class no longer inherits from str #86)
Strings added to HTML objects, now return HTML objects. E.g. HTML_value + str_value and str_value_ + HTML_value both return HTML objects. To maintain a str result, call str() on your HTML objects before adding them to strings. (feat(HTML)!: HTML class no longer inherits from str #86)

New features

Exported ReprHtml protocol class. If an object has a _repr_html_ method, then it is of instance ReprHtml. (feat(HTML)!: HTML class no longer inherits from str #86)
Exported is_tag_node() and is_tag_child() functions that utilize typing.TypeIs to narrow TagNode and TagChild type variables, respectively. (feat(HTML)!: HTML class no longer inherits from str #86)
Exported consolidate_attrs(*args, **kwargs) function. This function will combine the TagAttrs (supplied in *args) with TagAttrValues (supplied in **kwargs) into a single TagAttrs object. In addition, it will also return all *args that are not dictionary as a list of unaltered TagChild objects. (feat(HTML)!: HTML class no longer inherits from str #86)
The Tag method .add_style(style=) added support for HTML objects in addition to str values. (feat(HTML)!: HTML class no longer inherits from str #86)

Benefits:

No ambiguity between a str type and an HTML type.

-TagAttrValue = Union[str, float, bool, None]
+TagAttrValue = Union[str, float, bool, "HTML", None]


Given parity for other large union objects (TagNode and TagChild), I do not believe we should make a is_tag_attr_value() method as consolidate_attrs() should internally handle it.

For now, we will skip making this helper method.
