Gengo Test

Problem Statement

1. Write your own compression/decompression program in python, Go or Php, the program should be able to do the following:

   a. take a regular text file as input, output a compressed version of the same file

   b. decompressing the compressed file MUST produce the same hash as the original file

   c. Important points:

    i. You can use existing libraries for the compression/decompression process
   
    ii. Command line interface must be well-designed and along with de-jure  or de-facto standards.
   
    	1. For example please use youprogram.php(or .py) -c filetozip.txt and yourprogram.php (or .py) -u filetounzip.zip
   
    iii. Implementation must be well-organized, easy to read, efficient enough and appropriately commented.
   
    iv. Implementation must have enough amount of tests.

Setup

• Make sure latest versions of Node(v10+) and npm (v6+) are installed.
• Run npm install -g gengo-test (Must be -g/global to write out compressed files)

Usage

• gengo <command|alias> <text-file>

Commands

• compress|c - Zip file using gzip
• decompress|dc - Unzip file using gunzip
• checksum|cs - Generates hash using md5
• size|s - Gets the file size

Unit Tests

• npm test

Scaling Performance

• (Unix-like OSes) UV_THREADPOOL_SIZE=64
• (Windows) SET UV_THREADPOOL_SIZE=64

Uninstallation

• Run npm uninstall gengo-test
