Counting Line Numbers in Eclipse [closed]

Question

I have a Java project in Eclipse with ~10 packages and ~10 class files per package. Is there a way to determine total lines of code for the whole project from within Eclipse? I am familiar with other tools (e.g., Code Analyzer, wc, etc.) but I want to know if there is a way to do this within Eclipse (or get confirmation that there is no way to do it).

Answer 1

Here's a good metrics plugin that displays number of lines of code and much more:

http://metrics.sourceforge.net/

It says it requires Eclipse 3.1, although I imagine they mean 3.1+

Here's another metrics plugin that's been tested on Ganymede:

http://eclipse-metrics.sourceforge.net

Note that metrics2.sourceforge.net states that the first plugin above (metrics.sourceforge.net) is discontinued and metric2 is intended to be a continuation. – Cantonment

An information that would saved me a ton of time: The plugin needs to be activated for each project in your workspace individually, will modify your .project file and only provides metrics up to the project level, but not the workspace level. – Homology

both link seems dead – Bernadine

On Eclipse Mars 1, installing Metrics from the Help/Eclipse Marketplace failed - Metrics did not show up in Window/Show View/Other. Instead installing by adding it from metrics.sourceforge.net/update as described at metrics.sourceforge.net worked – Hag

Search > File Search

Check the Regular expression box.

Use this expression:

\n[\s]*

Select whatever file types (*.java, *.xml, etc..) and working sets are appropriate for you.

... and by check off you mean, make sure it is checked. Note that this method does not count empty lines. – Isochronize

You may or may not have got this from here. – Jaggers

This will use up a lot of memory on larger codebases, unfortunately. On my Indigo I hit 700k hits before eclipse died. Granted I only have -Xmx314M in my eclipse.ini – Redolent

This gives each file's LOC individually. not TOC – Asiatic

As mentioned by @PeterAjtai, it does not count empty lines. However, this will: \n[^\n]* – Feedback

@AbhishekSusarla You can run it on packages. – Romish

@CamJackson you're link is dead; anyway i definitely got it from somewhere, just can't remember else i'd have just posted the link... – Dervish

To return a count of non-blank, non-comment lines something like this could help. \n[^!//][\s]* – Hop

This search usually hangs Eclipse (4.2.1) on my moderate size project. – Booster

Answer 3

Under linux, the simpler is:

1. go to the root folder of your project
2. use find to do a recursive search of *.java files
3. use wc -l to count lines:

To resume, just do:

find . -name '*.java' | xargs wc -l

Guess, simpler depends on the defintion here. – Proofread

And people are installing an eclipse plugin to load their memory. As if it was already not loaded too much. – Serra

Worked well for me too. – Vitrain

Answer 4

For eclipse(Indigo), install (codepro).

After installation: - Right click on your project - Choose codepro tools --> compute metrics - And you will get your answer in a Metrics tab as Number of Lines.

This one is actually quite good! You should however fix the link as it gives a 404. – Kovach

Found this post that has a link to the latest version of codepro - and it works in Eclipse Oxygen: #29390808 – Trudietrudnak

Answer 5

Are you interested in counting the executable lines rather than the total file line count? If so you could try a code coverage tool such as EclEmma. As a side effect of the code coverage stats you get stats on the number of executable lines and blocks (and methods and classes). These are rolled up from the method level upwards, so you can see line counts for the packages, source roots and projects as well.

Answer 6

You could use a batch file with the following script:

@echo off
SET count=1
FOR /f "tokens=*" %%G IN ('dir "%CD%\src\*.java" /b /s') DO (type "%%G") >> lines.txt
SET count=1
FOR /f "tokens=*" %%G IN ('type lines.txt') DO (set /a lines+=1)
echo Your Project has currently totaled %lines% lines of code. 
del lines.txt
PAUSE

Answer 7

I think if you have MyEclipse, it adds a label to the Project Properties page which contains the total number of source code lines. Might not help you as MyEclipse is not free though.

Unfortunately, that wasn't enough in my case so I wrote a source analyzer to gather statistics not gathered by other solutions (for example the metrics mentioned by AlbertoPL).

Answer 8

A very simple plugin for counting actual lines of source code is step counter eclipse plugin. Please download and try.

github link

Place the downloaded jar file under eclipse\plugin folder and restart eclipse.

Rightclick and select step counter

Answer 9

You could use former Instantiations product CodePro AnalytiX. This eclipse plugin provides you suchlike statistics in code metrics view. This is provided by Google free of charge.

This is the same hint as Ashish gave, but with a working link. – Kovach
