Need script or Program to count lines of source code

Olnex · 2009-03-10 12:11:14

Hello, I need a script or a program that can count how many lines are there in a directory contains source code as well as other directories(contain code as well), there are .java files in these directories, the script or program should count number of lines with/without comments(starts with // or surrounded by /**/)

Thanks a lot!!!

cat *.java | grep -vP '^\s*[\/\*]+' | sed '/^\s*$/d' | wc -l

NOTE: I haven't really tested that.

I wrote a quick python program to count the lines in a file, you could just adapt it to your needs, or use the second program I have in this post that condenses all the .java files in a directory into a single text file, which you can then use a line-count on (useful if you need to print it as well - I wrote it for my IB dossier java project), if you'd like a proper script for your needs, otherwise check the other suggestions.

Run it by copying the code into a text file and saying it as script.py (change script to whatever you want) and running it with python /path/to/script.py

#!/usr/bin/env python
#Program to tally the lines in a file
#Author: lswest
import os

home=os.path.expanduser("~")
endPath=raw_input("Path to file relative to your home directory (include file name and extension): ")
count=0
ff=open(os.path.join(home, endPath))
for x in ff:
    count+=1
values={'name': os.path.join(home,endPath), 'count' : count}
print "The file %(name)s contains %(count)s lines." % values

#!/usr/bin/env python
#Script to condense the multiple files of a project into one for easy printing/copying
#Author: lswest
import os

home=os.path.expanduser("~")
endPath=raw_input("Path relative to your home directory to the project folder: ")
extension=raw_input("Extension of files you want to condense: ")
outPath=raw_input("Path to output file relative to home directory: ")
outFile=raw_input("Output file name (including extension): ")
ff=open(os.path.join(home+outPath,outFile), "wt")

for root, dirs, files in os.walk(os.path.join(home,endPath), "true", "none", "true"):
    for infile in [f for f in files if f.endswith(extension)]:
        fh=open(os.path.abspath(os.path.join(root,infile)))
        for line in fh:
            ff.write(line,)
        fh.close()

ff.close()

cat FILE | wc -l

Since excessive comments are only required for unclear code, shouldn't they be counted in LOC?

sloc is what you want

I just love the way it computes the number of guys supposedly needed to wirte the source code, how much time they should have spent, and concludes by estimating the cost of development.

You got pretty impressive results by running sloc on linux kernel sources

Arch Linux
