Eclipse count lines of code

Question

I ve tried the Metrics plugin and although it s nice and all  it s not what my boss is looking for  It counts a line with just one   as a line and he doesn t want that to count as  its not a line  its a style choice   I also need to generate some form of report about the metrics provided  Are there any good tools for this

One possible way to count lines of code in Eclipse:

using the Search / File... menu, select File Search tab, specify \n[\s]* for Containing text (this will not count empty lines), and tick Regular expression.

For static analysis  I ve used and recommend SonarQube which runs just about all the metrics you could possibly want on a wide range of languages  and is free in the basic version  you have to pay to analyse the sorts of languages I d only code in with a gun to my head    You have to install it as a web-app running the analysis off your source code repository  but it also has an Eclipse plugin   It s overkill if you just want to know  as a one-off  how many lines of code there are in your project  If you want to track metrics through time  compare across projects  fire warnings when a threshold is exceeded  etc   it s fantastic   Disclosure  I have no financial relationship with SonarSource

The first thing to do is to determine your definition of  line of code   LOC    In both your question     It counts a line with just one   as a line and he doesn t want that to   count as  its not a line  its a style choice    and in the answers  e g        You can adjust the Lines of Code metrics by ignoring blank and comment-only lines or exclude Javadoc if you want   you can tell that people have different opinions as to what constitutes a line of code   In particular  people are often imprecise about whether they really want the number of lines of code or the number of statements   For example  if you have the following really long line filled with statements  what do you want to report  1 LOC or hundreds of statements     a   1  b   2  if  a  c  b       etc  for another 1000 characters        And when somebody asks you what you are calling a LOC  make sure you can answer  even if it is just  my definition of a LOC is Metrics2 s definition    In general  for most commonly formatted code  unlike my example   the popular tools will give numbers fairly similar  so Metrics2  SonarQube  etc  should all be fine  as long as you use them consistently   In other words  don t count the LOC of some code using one tool and compare that value to a later version of that code that was measured with a different tool

ProjectCodeMeter counts LLOC  logical lines of code  exactly as you described  only effective lines   it integrates into eclipse as external code metrics tool  it s not real-time though  it generates a report actually it counts many source code metrics such as complexity  arithmetic intricacy  hard coded strings  numeric constants   even estimates development time in hours

There s always the  brute force     Search- File Type the following in  Containing text  -        Then check the  Regular Expression  checkbox Type the following in  File name patterns  -    java Click  Search  Check the number of matches in the  Search  Tab

Another tool is Google Analytix  which will also allow you to run metrics even if you can t build the project in case of errors

Install the Eclipse Metrics Plugin  To create a HTML report  with optional XML and CSV  right-click a project - gt  Export - gt  Other - gt  Metrics   You can adjust the Lines of Code metrics by ignoring blank and comment-only lines or exclude Javadoc if you want  To do this check the tab at Preferences - gt  Metrics - gt  LoC   That s it  There is no special option to exclude curly braces      The plugin offers an alternative metric to LoC called Number of Statements  This is what the author has to say about it      This metric represents the number of statements in a method  I consider it a more robust measure than Lines of Code since the latter is fragile with respect to different formatting conventions    Edit    After you clarified your question  I understand that you need a view for real-time metrics violations  like compiler warnings or errors  You also need a reporting functionality to create reports for your boss  The plugin I described above is for reporting because you have to export the metrics when you want to see them

If on OSX or  NIX use  Get all actual lines of java code from   java files  find   -name    java  -exec grep   a-zA-Z0-9             wc -l   Get all lines from the   java files  which includes empty lines and comments  find   -name    java  -exec cat   wc -l   Get information per File  this will give you   path to file         number of lines    find   -name    java  -exec wc -l

Another way would by to use another loc utility  like LocMetrics for instance  It also lists many other loc tools  The integration with Eclipse wouldn t be always there  as it would be with Metrics2  which you can check out because it is a more recent version than Metrics   but at least those tools can reason in term of logical lines  computed by summing the terminal semicolons and terminal curly braces   You can also check with eclipse-metrics is more adapted to what you expect
