code-metrics

When I am in a .java file the unused code is usually grayed out or has a green underline saying this code will probably (probably because of some weird JNI/Reflection corner cases) be unused. But I have this project with thousands of Java files and I want to find ALL INSTANCES of such probable-unused codes. How can I do that in IntelliJ IDEA? CrazyCoder Just use Analyze | Inspect Code with appropriate inspection enabled ( Unused declaration under Declaration redundancy group). Using IntelliJ 11 CE you can now "Analyze | Run Inspection by Name ... | Unused declaration" In latest IntelliJ

Is there a way to determine how many lines of code an Xcode project contains? I promise not to use such information for managerial measurement or employee benchmarking purposes. ;) Nathan Kinsinger Check out CLOC . cloc counts blank lines, comment lines, and physical lines of source code in many programming languages. ( Legacy builds are archived on SourceForge .) Joshua Nozzi I see this floating around and use it myself: find . "(" -name "*.m" -or -name "*.mm" -or -name "*.cpp" -or -name "*.swift" ")" -print0 | xargs -0 wc -l tiguero I have been using CLOC as mentioned by Nathan Kinsinger and

I've seen a number of 'code metrics' related questions on SO lately, and have to wonder what the fascination is? Here are some recent examples: what code metrics convince you that provided code is crappy when if ever is number of lines of code a useful metric writing quality tests In my mind, no metric can substitute for a code review, though: some metrics sometimes may indicate places that need to be reviewed, and radical changes in metrics over short time frames may indicate places that need to be reviewed But I cannot think of a single metric that by itself always indicates 'good' or 'bad'

If you were to mandate a minimum percentage code-coverage for unit tests, perhaps even as a requirement for committing to a repository, what would it be? Please explain how you arrived at your answer (since if all you did was pick a number, then I could have done that all by myself ;) Jon Limjap This prose by Alberto Savoia answers precisely that question (in a nicely entertaining manner at that!): http://www.artima.com/forums/flat.jsp?forum=106&thread=204677 Testivus On Test Coverage Early one morning, a programmer asked the great master: “I am ready to write some unit tests.
