Can you get the number of lines of code from a Git

Question

In a GitHub repository you can see “language statistics”, which displays the percentage of the project that’s written in a language. It doesn’t, however, display how many lines of code the project consists of. Often, I want to quickly get an impression of the scale and complexity of a project, and the count of lines of code can give a good first impression. 500 lines of code implies a relatively simple project, 100,000 lines of code implies a very large/complicated project.

So, is it possible to get the lines of code written in the various languages from a GitHub repository, preferably without cloning it?

The question “Count number of lines in a git repository” asks how to count the lines of code in a local Git repository, but:

1. You have to clone the project, which could be massive. Cloning a project like Wine, for example, takes ages.
2. You would count lines in files that wouldn’t necessarily be code, like i13n files.
3. If you count just (for example) Ruby files, you’d potentially miss massive amount of code in other languages, like JavaScript. You’d have to know beforehand which languages the project uses. You’d also have to repeat the count for every language the project uses.

All in all, this is potentially far too time-intensive for “quickly checking the scale of a project”.

Answer 1

Not currently possible on Github.com or their API-s

I have talked to customer support and confirmed that this can not be done on github.com. They have passed the suggestion along to the Github team though, so hopefully it will be possible in the future. If so, I'll be sure to edit this answer.

Meanwhile, Rory O'Kane's answer is a brilliant alternative based on cloc and a shallow repo clone.

Answer 2

If the question is "can you quickly get NUMBER OF LINES of a github repo", the answer is no as stated by the other answers.

However, if the question is "can you quickly check the SCALE of a project", I usually gauge a project by looking at its size. Of course the size will include deltas from all active commits, but it is a good metric as the order of magnitude is quite close.

E.g.

How big is the "docker" project?

In your browser, enter api.github.com/repos/ORG_NAME/PROJECT_NAME i.e. api.github.com/repos/docker/docker

In the response hash, you can find the size attribute:

{
    ...
    size: 161432,
    ...
}

This should give you an idea of the relative scale of the project. The number seems to be in KB, but when I checked it on my computer it's actually smaller, even though the order of magnitude is consistent. (161432KB = 161MB, du -s -h docker = 65MB)

Answer 3

You can simply run something like

git ls-files | xargs wc -l

which will give you the total count →
