Commits miner is a tool to process and extract useful information from commits history in git repositories. (Check: https://github.com/mateusfreira/commits-miner)
This small projects calculates code metrics in Java projects by means of static analysis (i.e. no need for compiled code). Currently, it contains a large set of metrics, including the famous CK metrics:
-
CBO (Coupling between objects): Counts the number of dependencies a class has. The tools checks for any type used in the entire class (field declaration, method return types, variable declarations, etc). It ignores dependencies to Java itself (e.g. java.lang.String).
-
DIT (Depth Inheritance Tree): It counts the number of "fathers" a class has. All classes have DIT at least 1 (everyone inherits java.lang.Object). In order to make it happen, classes must exist in the project (i.e. if a class depends upon X which relies in a jar/dependency file, and X depends upon other classes, DIT is counted as 2).
-
NOC (Number of Children): Counts the number of children a class has.
-
NOF (Number of fields): Counts the number of fields in a class, no matter its modifiers.
-
NOPF (Number of public fields): Counts only the public fields.
-
NOSF: Counts only the static fields.
-
NOM (Number of methods): Counts the number of methods, no matter its modifiers.
-
NOPM (Number of public methods): Counts only the public methods.
-
NOSM (Number of static methods): Counts only the static methods.
-
NOSI (Number of static invocations): Counts the number of invocations to static methods. It can only count the ones that can be resolved by the JDT.
-
RFC (Response for a Class): Counts the number of unique method invocations in a class. As invocations are resolved via static analysis, this implementation fails when a method has overloads with same number of parameters, but different types.
-
WMC (Weight Method Class) or McCabe's complexity. It counts the number of branch instructions in a class.
-
LOC (Lines of code): It counts the lines of count, ignoring empty lines.
-
LCOM (Lack of Cohesion of Methods): Calculates LCOM metric. This is the very first version of metric, which is not reliable. LCOM-HS can be better (hopefully, you will send us a pull request).
