Kirilov

Kirilov was born due to the necesitiy of installing packgaes in a remote machine that has no access to internet. The common thing to do is to setup a local environment with the same python version that exists in the remote machine, then you do pip freeze > requirements.txt and proceed to migrate all the code and to start installing the packages using the requirements.txt file.

However, in some cases the remote machine has no access to internet, so you first have to download the packages and install them in the remote server. Kirilov is a script that helps you to automate this. It will compare requirements and gives the option to download the recently added. With a simple command you can manage your requirements without much problem.

Install

  • Download the code
  • Inside the directory run: pip install .
  • The script has no dependecies

Usage

Kirilov receive two inputs: the two inputs in which we are going to do the comparison, it could be a file or data coming from pip freeze. Commonly these are the inputs you are going to use: requirements.txt and pip freeze.

Print new requirements and output them to a file

$ kirilov -f1=- -f2=requirements.txt

The - means pip freeze. The script is going to do a comparison between pip freeze and requirements.txt, then is going to print the requirmentes that do not exists in the requirements.txt file. The script is also going to create a file called kirilov_added.txt that will contain the new requirements.

Note: the order of inputs matters.

Download the new requirements

$ kirilov -f1=- -f2=requirements.txt --download=True --path=/path/for/your/downloads

You can especify the path in which you desire to save the downloads. The default is ./downloads.

All options

  • --output or -op: Output a file with the new requirements?. Default True
  • --download or -d: Download the new requirements? Default false
  • --path or -p: The path of the download directory. Default ./downloads
  • --file1 or -f1: Path to the first requirements file or '-'. The meaning of '-' is pip freeze
  • --file2 or -f2: Path to the second requirements file or '-'. The meaning of '-' is pip freeze
