Can you get the number of lines of code from a GitHub repository

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    You have to clone the project  which could be massive  Cloning a project like Wine  for example  takes ages  You would count lines in files that wouldn   t necessarily be code  like i13n files  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

You can use GitHub API to get the sloc like the following function

function getSloc(repo, tries) {

    //repo is the repo's path
    if (!repo) {
        return Promise.reject(new Error("No repo provided"));
    }

    //GitHub's API may return an empty object the first time it is accessed
    //We can try several times then stop
    if (tries === 0) {
        return Promise.reject(new Error("Too many tries"));
    }

    let url = "https://api.github.com/repos" + repo + "/stats/code_frequency";

    return fetch(url)
        .then(x => x.json())
        .then(x => x.reduce((total, changes) => total + changes[1] + changes[2], 0))
        .catch(err => getSloc(repo, tries - 1));
}

Personally I made an chrome extension which shows the number of SLOC on both github project list and project detail page. You can also set your personal access token to access private repositories and bypass the api rate limit.

You can download from here https://chrome.google.com/webstore/detail/github-sloc/fkjjjamhihnjmihibcmdnianbcbccpnn

Source code is available here https://github.com/martianyi/github-sloc

If you go to the graphs contributors page  you can see a list of all the contributors to the repo and how many lines they ve added and removed  Unless I m missing something  subtracting the aggregate number of lines deleted from the aggregate number of lines added among all contributors should yield the total number of lines of code in the repo   EDIT  it turns out I was missing something after all  Take a look at orbitbot s comment for details   UPDATE  This data is also available in GitHub s API  So I wrote a quick script to fetch the data and do the calculation   x000D   x000D   use strict    async function countGithub repo        const response   await fetch  https   api github com repos   repo  stats contributors       const contributors   await response json        const lineCounts   contributors map contributor   gt            contributor weeks reduce  lineCount  week    gt  lineCount   week a - week d  0              const lines   lineCounts reduce  lineTotal  lineCount    gt  lineTotal   lineCount       window alert lines      countGithub  jquery jquery       or count anything you like x000D   x000D   x000D   Just paste it in a Chrome DevTools snippet  change the repo and click run  Disclaimer  thanks to lovasoa   Take the results of this method with a grain of salt  because for some repos  sorich87 bootstrap-tour  it results in negative values  which might indicate there s something wrong with the data returned from GitHub s API  UPDATE  Looks like this method to calculate total line numbers isn t entirely reliable  Take a look at orbitbot s comment for details

You can clone just the latest commit using git clone --depth 1  lt url gt  and then perform your own analysis using Linguist  the same software Github uses   That s the only way I know you re going to get lines of code   Another option is to use the API to list the languages the project uses   It doesn t give them in lines but in bytes   For example       curl https   api github com repos evalEmpire perl5i languages      Perl   274835     Though take that with a grain of salt  that project includes YAML and JSON which the web site acknowledges but the API does not   Finally  you can use code search to ask which files match a given language   This example asks which files in perl5i are Perl   https   api github com search code q language perl repo evalEmpire perl5i   It will not give you lines  and you have to ask for the file size separately using the returned url for each file

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

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

Hey all this is ridiculously easy     Create a new branch from your first commit When you want to find out your stats  create a new PR from main The PR will show you the number of changed lines - as you re doing a PR from the first commit all your code will be counted as new lines  And the added benefit is that if you don t approve the PR and just leave it in place  the stats  No of commits  files changed and total lines of code  will simply keep up-to-date as you merge changes into main     Enjoy

A shell script  cloc-git  You can use this shell script to count the number of lines in a remote Git repository with one command      usr bin env bash git clone --depth 1   1  temp-linecount-repo  amp  amp    printf    temp-linecount-repo  will be deleted automatically  n n n   amp  amp    cloc temp-linecount-repo  amp  amp    rm -rf temp-linecount-repo   Installation  This script requires CLOC     Count Lines of Code     to be installed  cloc can probably be installed with your package manager     for example  brew install cloc with Homebrew  There is also a docker image published under mribeiro cloc   You can install the script by saving its code to a file cloc-git  running chmod  x cloc-git  and then moving the file to a folder in your  PATH such as  usr local bin   Usage  The script takes one argument  which is any URL that git clone will accept  Examples are https   github com evalEmpire perl5i git  HTTPS  or git github com evalEmpire perl5i git  SSH   You can get this URL from any GitHub project page by clicking    Clone or download      Example output     cloc-git https   github com evalEmpire perl5i git Cloning into  temp-linecount-repo     remote  Counting objects  200  done  remote  Compressing objects  100   182 182   done  remote  Total 200  delta 13   reused 158  delta 9   pack-reused 0 Receiving objects  100   200 200   296 52 KiB   110 00 KiB s  done  Resolving deltas  100   13 13   done  Checking connectivity    done    temp-linecount-repo  will be deleted automatically         171 text files       166 unique files                                                  17 files ignored   http   cloc sourceforge net v 1 62  T 1 13 s  134 1 files s  9764 6 lines s  ------------------------------------------------------------------------------- Language                     files          blank        comment           code ------------------------------------------------------------------------------- Perl                           149           2795           1425           6382 JSON                             1              0              0            270 YAML                             2              0              0            198 ------------------------------------------------------------------------------- SUM                            152           2795           1425           6850 -------------------------------------------------------------------------------   Alternatives  Run the commands manually  If you don   t want to bother saving and installing the shell script  you can run the commands manually  An example     git clone --depth 1 https   github com evalEmpire perl5i git   cloc perl5i   rm -rf perl5i   Linguist  If you want the results to match GitHub   s language percentages exactly  you can try installing Linguist instead of CLOC  According to its README  you need to gem install linguist and then run linguist  I couldn   t get it to work  issue  2223
