Utility To Count Number Of Lines Of Code In Python Or Bash

Tags:

lines-of-code

Is there a quick and dirty way in either python or bash script, that can recursively descend a directory and count the total number of lines of code? We would like to be able to exclude certain directories though.

For example:

start at: /apps/projects/reallycoolapp
exclude: lib/, frameworks/

The excluded directories should be recursive as well. For example:

/app/projects/reallycool/lib SHOULD BE EXCLUDED
/app/projects/reallycool/modules/apple/frameworks SHOULD ALSO BE EXCLUDED

This would be a really useful utility.

How do you count lines of code in Python?

Use os. walk to traverse the files and sub directories, use endswith to filter the files you want to count, open each file and use sum(1 for line in f) to count the lines, aggregate all the file line counts.

How do I count lines in bash?

wc. The wc command is used to find the number of lines, characters, words, and bytes of a file. To find the number of lines using wc, we add the -l option. This will give us the total number of lines and the name of the file.

How do you count the number of lines of code?

To use cloc simply type cloc followed by the file or directory which you wish to examine. Now lets run cloc on it. As you can see it counted the number of files, blank lines, comments and lines of code. Another cool feature of cloc is that can even be used on compressed files.

Found an awesome utility CLOC. https://github.com/AlDanial/cloc

Here is the command we ran:

perl cloc.pl /apps/projects/reallycoolapp --exclude-dir=lib,frameworks
