kloc - generate statistics for C/C++ code
kloc [file...]
kloc reads C++ source code, and outputs the following statistics concerning it:
- Number of lines:
- The total number of lines read.
- Lines of code:
- The number of lines containing at least one uncommented token.
- Preprocessor statements:
- The number of preprocessor statements. (A preprocessor statement is a line in which the first non-space character is a '#' character.)
- Statements:
- The total number of C++ statements (including preprocessor statements).
- Lines of comments:
- The number of lines which contain a comment of some sort.
- Functions:
- The number of function definitions.
- Lines in functions:
- Only if at least one function definition is present, the number of lines containing at least one uncommented token in all of the functions found.
- Average lines per function:
- Only if at least one function defintion is present, the number of code lines in all of the functions, divided by the number of functions.
The following operands are supported:
- file
- A pathname of a file to read. If no file operands are specified, the standard input shall be used.
0 no error. 2 One of the input files could not be opened. 3 Hardware error on standard out.
Doesn't truly process pre-processor statements (except for counting them); in particular, conditional compilation is ignored, so both the true and the false branches are counted.
The "parser" is extremely crude, and can easily be fooled.
The number of statements as just a crude approximation, just a count of the number of ';' tokens in the code.
