guide and overview of the changes!
Breaking changes
Ruff now enables a much larger set of rules by default (413, up from 59). See the blog post for
more details and the new Default Rules page for a
full listing of the enabled rules. Note that this is primarily an expansion, but 18 of the more
opinionated pycodestyle (
E) and pyflakes (F) rules have been removed from the default set:E401,E402,E701,E702,E703,E711,E712,E713,E714,E721,E731,E741,E742,E743,F403,F405,F406, andF722.Ruff can now format Python code blocks in Markdown files and will do this by default. See the
documentation for more details.
Ruff now supports
ruff: ignorecomments at the ends of lines, likenoqacomments, or on the line preceding a diagnostic. For example, these both suppress anunused-import(F401) diagnostic:Fixes are now shown in
checkandformat --checkoutput:This example also shows off the Markdown formatting.
format --checknow supports the same output formats as the linter, including thegithubandgitlaboutputs for rendering annotations in CI:See the CLI help or documentation for the
full list of supported formats.
The
filename,location,end_location,fix.edits[].location, andfix.edits[].end_locationfields in the JSON output format may now be
nullrather than defaulting to the empty string androw 1, column 1, respectively.

builtins._.suspicious-url-open-usage(
