Generate a URL Summary

You can generate a summary of a URL without retrieving the page using the get_url_summary function.

By default, this function can generate a summary for the following URLs:

• github.com

• twitter.com

• eventbrite.com / eventbrite.co.uk

• upcoming.com

• calagator.com

• events.indieweb.org

• indieweb.org

indieweb_utils.get_url_summary(url: str, custom_templates: list | None = None)

Return a text summary for given url.

Parameters:

• url – The URL to summarize.

• custom_templates – A list of tuples with patterns against which to check when generating a summary associated with results to return.

Returns:

A summary of the URL.

Return type:

str

import indieweb_utils

# a dictionary of custom patterns against which to match during the lookup
custom_properties = {
    "jamesg.blog": [
        (r"coffee/maps/(?P<location>.+)", "A map of {location} coffee shops on jamesg.blog")
    ]
}

summary = indieweb_utils.get_summary("https://github.com/capjamesg/indieweb-utils/pulls/1")

print(summary) # "A comment on a pull request in the indieweb-utils GitHub repository"

summary = indieweb_utils.get_summary("https://jamesg.blog/coffee/maps/london")

print(summary) # "A map of london coffee shops on jamesg.blog"

You can specify custom mappings for other domains using the custom_mappings parameter.

This parameter accepts a dictionary of with domain names mapped to lists of tuples with patterns to match and strings to return, like this:

{
    "example.com": [
        (r"example.com/(\d+)", "Example #{}"),
    ]
}

If a summary cannot be generated, this function returns “A post by [domain_name].”, where domain name is the domain of the URL you passed into the function.
