Overview
The Gnome strategy identifies versions of software at gnome.org by
checking the available downloads found in a project’s cache.json
file.
GNOME URLs generally follow a standard format:
https://download.gnome.org/sources/example/1.2/example-1.2.3.tar.xz
Before version 40, GNOME used a version scheme where unstable releases
were indicated with a minor that’s 90+ or odd. The newer version scheme
uses trailing alpha/beta/rc text to identify unstable versions
(e.g., 40.alpha
).
When a regex isn’t provided in a livecheck
block, the strategy uses
a default regex that matches versions which don’t include trailing text
after the numeric version (e.g., 40.0
instead of 40.alpha
) and it
selectively filters out unstable versions below 40 using the rules for
the older version scheme.

-
.find_versions(url:, regex: nil, **unused, &block) ⇒ Hash{Symbol => T.untyped}
Generates a URL and regex (if one isn’t provided) and passes them to PageMatch.find_versions to identify versions in the content.
-
.generate_input_values(url) ⇒ Hash{Symbol => T.untyped}
Extracts information from a provided URL and uses it to generate various input values used by the strategy to check for new versions.
-
.match?(url) ⇒ Boolean
Whether the strategy can be applied to the provided URL.

.generate_input_values(url) ⇒ Hash{Symbol => T.untyped}
Extracts information from a provided URL and uses it to generate
various input values used by the strategy to check for new versions.
Some of these values act as defaults and can be overridden in a
livecheck
block.
