Suggestion for fixing 'Hashtag linking doesn't work'

[usartwork]

Implementation is easy via facet type "tag"
In parse_facets() add
for t in parse_tags(text):
facets.append(
{
"index": {
"byteStart": t["start"],
"byteEnd": t["end"],
},
"features": [
{
"$type": "app.bsky.richtext.facet#tag",
"tag": t["tag"],
}
],
}
)

add method parse_tags()

def parse_tags(text: str) -> List[Dict]:
spans = []
url_regex = rb"(?:\s|^)(?:#(?!(?:\d+|\w+?|\w*?)(?:\s|$)))(\w+)(?=\s|$)"
text_bytes = text.encode("UTF-8")
for m in re.finditer(url_regex, text_bytes):
spans.append(
{
"start": m.start(1),
"end": m.end(1),
"tag": m.group(1).decode("UTF-8"),
}
)
return spans
