1.. title:: clang-tidy - readability-function-size 2 3readability-function-size 4========================= 5 6`google-readability-function-size` redirects here as an alias for this check. 7 8Checks for large functions based on various metrics. 9 10Options 11------- 12 13.. option:: LineThreshold 14 15 Flag functions exceeding this number of lines. The default is `none` (ignore 16 the number of lines). 17 18.. option:: StatementThreshold 19 20 Flag functions exceeding this number of statements. This may differ 21 significantly from the number of lines for macro-heavy code. The default is 22 `800`. 23 24.. option:: BranchThreshold 25 26 Flag functions exceeding this number of control statements. The default is 27 `none` (ignore the number of branches). 28 29.. option:: ParameterThreshold 30 31 Flag functions that exceed a specified number of parameters. The default 32 is `none` (ignore the number of parameters). 33 34.. option:: NestingThreshold 35 36 Flag compound statements which create next nesting level after 37 `NestingThreshold`. This may differ significantly from the expected value 38 for macro-heavy code. The default is `none` (ignore the nesting level). 39 40.. option:: VariableThreshold 41 42 Flag functions exceeding this number of variables declared in the body. 43 The default is `none` (ignore the number of variables). 44 Please note that function parameters and variables declared in lambdas, 45 GNU Statement Expressions, and nested class inline functions are not counted. 46
