This is an extension for Python-Markdown to support hashtag parsing to clickable links.
# Heading
#hashtag at beginning of line and #within line.
This is no#hashtag.
#Markdown
will be rendered to:
<h1>Heading</h1> <p><a class="hashtag" href="https://tags.example.com/hashtag">#hashtag</a> at beginning of line and <a class="hashtag" href="https://tags.example.com/within">#within</a> line.</p> <p>This is no#hashtag. </p> <p><a class="hashtag" href="https://tags.example.com/Markdown">#Markdown</a></p>
You can easily specify the used link prefix and the class name of the link, see # Usage below.
The markdown-hashtag package can be installed via:
pip install markdown-hashtag
The following python code example shows how to use the hashtag extension and style the hashtag links in a pretty way with CSS (similar to how Obsidian renderns hashtags).
Note that you can define the link prefix of the href attribute and the class name by defining extension_configs in the markdown.markdown() function, see example.
import markdown
text = """\
# Heading
#hashtag at beginning of line and #within line.
This is no#hashtag.
#Markdown
<style>
a.hashtag {
background-color: #e0e0e0; /* hellgrauer Hintergrund */
border-radius: 4px; /* abgerundete Ecken */
padding: 2px 6px; /* innen etwas Abstand */
color: #3b6ea5; /* blaue Farbe für Links */
text-decoration: none; /* keine Unterstreichung */
font-weight: 500; /* etwas fetter */
font-family: -apple-system, BlinkMacSystemFont, "Segoe UI", Roboto, Helvetica, Arial, sans-serif;
cursor: pointer;
transition: background-color 0.2s ease;
}
a.hashtag:hover {
background-color: #cfd8dc; /* dunkleres Grau beim Hover */
text-decoration: underline; /* Unterstreichung beim Hover */
}
</style>
"""
html = markdown.markdown(text,
extensions=["hashtag"],
extension_configs={
"hashtag": {
"base_url": "https://tags.example.com/",
"span_class": "hashtag"
}
}
)
print(html)
