Pre-receive hook to check the binary file

Question

I am trying to restrict the binary file(dll, pdf, exe) committing in our GitLab instance. My moto is need to abort the commit if the commit have binary files. I have the code for aborting the commit in Python,

#!/usr/bin/env python3

import os

def scanDir(dirName):
    for root, dirs, files in os.walk(dirName):
        for fileName in files:
            if fileName.split('.')[-1] in ["txt","dll","pdf"]:
                return 1
    return 0

My problem in Gitlab have hooks file in ruby, My code is in python, So It doesn`t works in ruby code. (How to load the python file in ruby hook?)

Also I do not know what is path should I need to give in def scanDir(dirName): I tried my level best , But I can`t able do this in ruby because I newbie to ruby.

Can anyone help to add the hook to restrict the binary file?

GitLab hooks might be in any language.

It’s unclear why you can’t just use your python code as is.

FWIW, the translated code would be:

def scan_dir(dir_name)
  Dir["#{dir_name}/**/*"].any? do |f|
    %w|.txt .pdf .dll|.include?(File.extname(f))
  end
end

Thanks for your guiding, What dir_name could I pass to check the files? – Sep 07 '17 at 12:37
I am unsure about `GitLab`, but I think it would be a project root folder. – Aleksei Matiushkin Sep 07 '17 at 12:39
Ok, In your answer where the code returns 0 or 1 because there is no exit command, That`s why I asked – Sep 07 '17 at 12:42

`1` and `0` in python are for truthy and falsey. In ruby, the result of the last line of a method is returned, hence the result of call to `any?` is returned. – Aleksei Matiushkin Sep 07 '17 at 12:44
Could you let me know the way to pass the argument to `scan_def` method? if the path is `/home/git/repositories/` – Sep 07 '17 at 12:51

I have no clue what `scan_def` is. The argument is passed to the method as in literally all other languages: `method(argument)`. If an argument is the same in most calls, it might be made a default via `def scan_dir(dir_name = "/home/git/repositories/")` and the method might be called without an argument to enable default. – Aleksei Matiushkin Sep 07 '17 at 12:52
Above code is not working for me, I totally wrong calculated the workflow of the git and worked stupidly. I found a clue in this question https://stackoverflow.com/questions/26955973 to get the staged file in git by **ruby**. But don`t know how to use the answer in ruby code for my this question https://stackoverflow.com/questions/46095928. Could you help me? – Sep 22 '17 at 10:02
