.. title:: clang-tidy - readability-function-size
readability-function-size
=========================
`google-readability-function-size` redirects here as an alias for this check.
Checks for large functions based on various metrics.
Options
-------
.. option:: LineThreshold
Flag functions exceeding this number of lines. The default is `-1` (ignore
the number of lines).
.. option:: StatementThreshold
Flag functions exceeding this number of statements. This may differ
significantly from the number of lines for macro-heavy code. The default is
`800`.
.. option:: BranchThreshold
Flag functions exceeding this number of control statements. The default is
`-1` (ignore the number of branches).
.. option:: ParameterThreshold
Flag functions that exceed a specified number of parameters. The default
is `-1` (ignore the number of parameters).
.. option:: NestingThreshold
Flag compound statements which create next nesting level after
`NestingThreshold`. This may differ significantly from the expected value
for macro-heavy code. The default is `-1` (ignore the nesting level).
.. option:: VariableThreshold
Flag functions exceeding this number of variables declared in the body.
The default is `-1` (ignore the number of variables).
Please note that function parameters and variables declared in lambdas,
GNU Statement Expressions, and nested class inline functions are not counted.
