Software Metrics Analyzer for C,C++,Java Programs . All of the measures are relevant at method level and can reasonably be presented as averages per method at class, package and system level. $operators[0]="+"; // list of operators $totalops += (2 * substr_count ( $code, "//")); echo "Effort:"; $operators[2]="*"; $effort = $difficulty * $volume; Use Git or checkout with SVN using the web URL. download the GitHub extension for Visual Studio. It is quite hard to count that in language like Java, which is not procedural but object oriented. Some software measures are still not widely used in industry, despite the fact that they were defined many years ago, and some additional insights might be gained by revisiting them today with the benefit of recent lessons learned about how to analyze their design. Halstead IFM Limited is registered in England & Wales no. $totalops -= substr_count ( $code, "++"); Key Halstead Calculator echo "distinct operands (n2): $n2"; It is calculated as the program length times the 2-base logarithm of the vocabulary size (n): V = N * log2 (n) Halstead's volume (V) describes the size of the implementation of an algorithm. $totalops += substr_count ( $code, "&&"); echo "distinct operators (n1): $n1"; All of the Halstead metrics can be calculated at the method level. if ($n1<0 || $N1<0 || $N2 < 0) NOTE: This response contains a reference to a third party World Wide Web site.Microsoft is providing this information as a convenience to you. $distinctops++; These are language dependent; CppDepend uses the following definitions when computing Halstead metrics for C and C++. $totalops = substr_count ($code, "+"); Note that the -isystem option is here to avoid conflicts with gcc installations. echo "$difficulty"; The program volume (V) is the information contents of the program, measured in mathematical bits. for ($i=0; $i<7; $i++) echo "Difficulty:"; Download Halstead Metrics Tool for free. Halstead metrics measure a program's computational complexity from source code by counting a program's operators and operands to derive measurements of a program's length, vocabulary, volume, difficulty, and effort. THE METRICS WHICH ARE CALCULATED HALSTEAD'S MEASURES DESCRIPTION OF THE AVAILABLE MEASURES THE HISTORY OF SOFTWARE METRICS REFERENCES RESTRICTIONS SEE ALSO NAME nag_metrics - NAGWare f77 Tools Metrics DESCRIPTION nag_metrics is the NAGWare f77 Tools Fortran 77 complexity measurement tool. $totalops += substr_count ( $code, "-"); According to Halstead's "A computer program is an implementation of an algorithm considered to be a collection of tokens which can be classified as either operators or operand." $operators[1]="-"; echo " Results:"; Hello, I did not use any Halstead Metric tools, does a third part tool, like, Resource Standard Metrics help? V = N * log2 (n) } echo "total operators (N1): $N1"; Token Count. The calculation begins with a … Because they are applied to code, they are most often used as a maintenance metric. If you need C++11 support just add -std=c++11 after --. $operators[6]="||"; if ($flag == "auto") $totalops += substr_count ( $code, "||"); Learn more. McCabe Complexity Metrics In his paper A Complexity Measure, IEEE Transactions on Software Engineering, Dec 1976, Thomas McCabe defined a set of metrics to characterize the complexity of a software module's internal control flow logic.Glen Myers suggested a revision to the calculation in An Extension to the Cyclomatic Measure of Program Complexity, SIGPLAN Notices, Oct 1977.
