SHOW METRICS and SHOW COMPLEXITIES

Syntax:

[DO NOT] SHOW METRICS

[DO NOT] SHOW [CYCLOMATIC] COMPLEXITY

[DO NOT] SHOW [CYCLOMATIC] COMPLEXITIES

Function:

FPT reports metrics for the code analysed. The metrics reported are:

Files

Code and Comments

Program units

Program flow and cyclomatic complexity

Usage of Names for Objects Other than Local Variables

Cyclomatic complexities of sub-programs

Before the metrics report is made, FPT checks whether the code metrics have been disturbed by software engineering and formatting commands made earlier in processing. If this has occurred a note is issued, e.g.:

------------------------------------------------------------------------------
NOTE             Number 3025  Severity 0 (Worst 2)   Count 6205
     Line counts have been changed by software engineering commands
------------------------------------------------------------------------------

FPT also carries out the program flow analysis, checking for unreachable code, if this analysis has not already been made. Warnings may be issued if unreachable code sections are detected.

Where to use these commands:

Operating system command line

Yes


Configuration file, config.fsp

Yes


Specification (FSP) files, *.fsp

Yes


Interactively, to FPT> prompt:

Yes


Interactive command files

Yes


Embedded in the Fortran code

No


Default:

The report is not made by default (Note that defaults may be changed in the configuration file).

Example:

The file metrics table for the major climate and weather modelling code, WRF V3.4.1 is shown below. Note that the call depth metric is spurious because routines are called recursively.
