Size

LOC

size.loc — Physical lines of code.

Item	Value
Definition	Number of lines in the file.
Scope	file, project
Input	File source text
Calculation	Count of lines; a trailing newline does not start a new line. Project: sum over files.
Unit	lines
Language Applicability	language_independent
Limitations	-
Reference	-

SLOC

size.sloc — Source lines of code.

Item	Value
Definition	Lines occupied by at least one non-comment token.
Scope	function, file, project
Input	File source text, Token ranges
Calculation	A token spanning several lines (e.g. a multi-line string) occupies each of them. Function: lines of the function's range (including nested functions). Project: sum.
Unit	lines
Language Applicability	language_independent
Limitations	-
Reference	-

Comment LOC

size.comment_loc — Lines containing only comments.

Item	Value
Definition	Lines occupied by a comment token and by no other token.
Scope	file, project
Input	File source text, Token ranges
Calculation	Lines with code and a trailing comment are SLOC, not Comment LOC. Project: sum.
Unit	lines
Language Applicability	language_independent
Limitations	Documentation strings that are string literals (e.g. Python docstrings) count as SLOC.
Reference	-

Blank LOC

size.blank_loc — Blank lines.

Item	Value
Definition	Whitespace-only lines not occupied by any token.
Scope	file, project
Input	File source text, Token ranges
Calculation	Blank lines inside a multi-line comment or string are not blank. Project: sum.
Unit	lines
Language Applicability	language_independent
Limitations	-
Reference	-

Comment Ratio

size.comment_ratio — Share of comment lines.

Item	Value
Definition	Comment LOC / LOC.
Scope	file, project
Input	size.comment_loc, size.loc
Calculation	not_applicable when LOC is 0. Project: ratio of the sums.
Unit	ratio
Language Applicability	language_independent
Limitations	-
Reference	-

Statement Count

size.statement_count — Number of statements.

Item	Value
Definition	Nodes of kind statement, declaration, branch, loop, return or jump.
Scope	function, file, project
Input	Node kinds
Calculation	Function scope includes nested functions. Project: sum.
Unit	count
Language Applicability	partially_language_dependent
Limitations	Languages differ in what is a statement (e.g. C for-loop initializer declarations count; Python has no equivalent).
Reference	-

Token Count

size.token_count — Number of non-comment tokens.

Item	Value
Definition	Tokens of every kind except comment.
Scope	function, file, project
Input	Tokens
Calculation	A string literal is one token. Function scope includes nested functions. Project: sum.
Unit	count
Language Applicability	partially_language_dependent
Limitations	Token granularity follows each grammar (e.g. C #include is one token).
Reference	-

Function Count

size.function_count — Number of functions.

Item	Value
Definition	Functions in the IR, including methods, nested and anonymous functions.
Scope	file, project
Input	Functions
Calculation	Project: sum.
Unit	count
Language Applicability	language_independent
Limitations	-
Reference	-

Function Length

size.function_length — Lines spanned by a function.

Item	Value
Definition	Last line - first line + 1 of the function's source range.
Scope	function
Input	Function source range
Calculation	Includes the signature, blank and comment lines, and nested functions.
Unit	lines
Language Applicability	language_independent
Limitations	-
Reference	-

Average Function Length

size.avg_function_length — Mean Function Length.

Item	Value
Definition	Mean of size.function_length over all functions.
Scope	file, project
Input	size.function_length
Calculation	not_applicable when there are no functions.
Unit	lines
Language Applicability	language_independent
Limitations	-
Reference	-

Maximum Function Length

size.max_function_length — Longest Function Length.

Item	Value
Definition	Maximum of size.function_length over all functions.
Scope	file, project
Input	size.function_length
Calculation	not_applicable when there are no functions.
Unit	lines
Language Applicability	language_independent
