Eclipse plugin for measuring lines of code

Question

I'm running Eclipse Helios (3.6) and was wondering if there is a nice plugin out there that will count the number of logical lines of code in a java source file. By logical, I mean

if (j > 6) {
   j--;
}

In other words, 2 logical lines of code (2 statements) will be counted instead of 3 physical lines of code.

Answer 1

Metrics2 is an updated version of the Metrics plug-in described by js3v that should do what you need. It can also aggregate some of the measurements (e.g. add up the LOC of classes in a package to give you the LOC of the package). This page explains some of its capabilities and mentions that it counts logical lines of code, not physical ones.

Answer 2

I have been using checkstyle-cs, a free Eclipse plug-in. Besides logical lines of code, it will also compute cyclomatic and N-path complexity (which may be a better indicator of code problems).

While I don't know if it will generate a report on every module, you might try setting the threshold very low, (like 2). Checkstyle should give you a yellow highlight at the start of every method, telling you how many lines of code it found.

Incidentally, there was some disagreement on our team as to whether

a[i++] = 7;

was one statement or two. There was no disagreement that

a[i] = 7;
i++; 

counted as two statements.
