Markdown widget - hyperlinks does not open browser on click

[thomasht86]

Have you checked closed issues? https://github.com/Textualize/textual/issues?q=is%3Aissue+is%3Aclosed
Yes.

To reproduce:

# Sample textual app that renders markdown widget with url link
from textual.widgets import Markdown
from textual.app import App, ComposeResult

MARKDOWN = """
# This is an h1

Rich can do a pretty *decent* job of rendering markdown.

1. This is a list item
2. This is another list item

[Google](https://www.google.com)
"""

class HyperlinkApp(App):

    def compose(self) -> ComposeResult:
        yield Markdown(MARKDOWN)

if __name__ == "__main__":
    app = HyperlinkApp()
    app.run()

When running corresponding rich-snippet, it does open the url in browser on click.

from rich.console import Console
from rich.markdown import Markdown

console = Console()
md = Markdown(MARKDOWN)
console.print(md)

If this is not supported, I will be happy to change it to a feature request.

It's left to the developer to implement how to open links. If you want links to open a browser you can handle the LinkClicked message.

Ah, ok! Noted. Thanks for the swift reply.
Did you consider keeping the default behavior to open a browser from rich?
Thanks a lot for all your great work btw. 🙏
Really good devX!

The links in Rich work differently. They are handled by the terminal, which typically opens them in a browser. But you can't intercept those links. The links in Textual Markdown offer more flexibility, because an app can intercept them.

I see. Thanks again!

    import webbrowser
    @on(Markdown.LinkClicked)
    def handle_link_clicked(self, event: Markdown.LinkClicked) -> None:
        # Open in a new tab, if possible, else in the default browser
        webbrowser.open_new_tab(event.href)

worked like a charm! 👍
