Finally,
% fossl show MIT -text > LICENSE
creates a LICENSE file for a new project.
fossl
can also be used as a Python package, allowing Python code to access license information.
Limitations
GitHub limits the number of queries a user may make per hour. For unauthenticated users like fossl
, that rate limit is 60 / hour. fossl
caches license information locally (~/.config/fossl.toml
) to work around the rate limit. The license cache is updated every 90 days or if the cache file is deleted.
