This is a Python script to count line of code under specified directory.
Borrow from https://code.activestate.com/recipes/580709-lines-of-code-loc/, changed for java source code.
Basic Lines-Of-Code counter in Java source files, reporting the number of blank, comment and source code lines and total number of lines in all java files scanned. It also can extract all java source code into one big file.
Usage example:
% python locs.py -rec ./Projects
343 *.java files in: ['D:\\projects\\Projects']
5868 blank (10.6%), 12843 comment (23.2%), 36728 source (66.2%), 49571 source+comment (89.4%), 55439 total lines
(0.241 secs, 229978 lines/sec)
Extract all src into ./all_src.txt
Scan multiple directory
% python3 locs.py -rec ./Projects ./Projects2
343 *.java files in: ['D:\\projects\\Projects']
5868 blank (10.6%), 12843 comment (23.2%), 36728 source (66.2%), 49571 source+comment (89.4%), 55439 total lines
(0.241 secs, 229978 lines/sec)
Extract all src into ./all_src.txt
Statistic line of code and extract all java source code to one big file './all_src.java'
% python locs.py -rec -ext ./Projects
343 *.java files in: ['D:\\projects\\Projects']
5868 blank (10.6%), 12843 comment (23.2%), 36728 source (66.2%), 49571 source+comment (89.4%), 55439 total lines
(0.241 secs, 229978 lines/sec)
Extract all src into ./all_src.txt
% python3 locs.py -h
usage: locs.py [-help] [-recurse] [-extract] [-verbose] <file_or_dir_name> ...
