Miscellaneous-MaxComplexity

Functions must not exceed cyclomatic complexity limit

Required inputs: IR

Complex control flow can make code hard to understand. Try splitting up the code into multiple functions that can be understood individually.

Note

Cyclomatic complexity is also available as a metric, which can be configured to produce a metric violation when limits are exceeded. This stylecheck rule is available as an alternative to the metric.

Possible Messages

Key	Text	Severity	Disabled
cyclomatic_complexity_with_value	Cyclomatic complexity of {} exceeds limit of {}.	None	False
excessive_cyclomatic_complexity	Cyclomatic complexity exceeds limit of {}.	None	False

Options

• This rule shares the following common options: exclude_in_macros, exclude_messages_in_system_headers, excludes, extend_exclude_to_macro_invocations, includes, justification_checker, languages, post_processing, provider, report_at, severity

• This rule shares the following common metric options: macro_library_patterns, opaque_macros

• The following places define options that affect this rule: Stylechecks, Analysis-GlobalOptions
