Nesting

Maximum Nesting Depth

nesting.max_depth — Deepest nesting of control structures.

Item	Value
Definition	Maximum over control structures (branch, loop, case, catch) of 1 + the number of control structures enclosing it.
Scope	function, file, project
Input	Node kinds and parent links
Calculation	else if / elif continue their if-chain and do not add a level. Nesting restarts at function boundaries. 0 when there is no control structure. File / Project: maximum.
Unit	levels
Language Applicability	language_independent
Limitations	A branch directly inside a branch without a block (C if (a) if (b) x;) is treated as an if-chain continuation.

Average Nesting Depth

nesting.avg_depth — Mean nesting level of statements.

Item	Value
Definition	Mean over statements of the number of control structures enclosing the statement.
Scope	function, file, project
Input	Node kinds and parent links
Calculation	Statements as in size.statement_count. not_applicable when there are no statements. File / Project: mean over all their statements.
Unit	levels
Language Applicability	language_independent
Limitations	Inherits the statement differences of size.statement_count.
