NiTch

incredibly fast system fetch written in nim👑

Description 📖

nitch is a small and incredibly fast system fetch written fully in nim👑 without any dependencies, on my pc it executes in around 1.70 miliseconds.

The source code of nitch is highly documented and I hope it will act as a learning resource for nim and linux systems architecture

If anything in the source code is unclear or is lacking in its explanation, open an issue. Sometimes you get too close to something and you fail to see the "bigger picture"!

btw written in nim👑

why nim👑? because it's fast and simple

Installation ☁️

wget https://raw.githubusercontent.com/unxsh/nitch/main/setup.sh && sh setup.sh

Usage 🪨

nitch

flags:

 -f --fetch   | return fetch about system
 -h --help    | return help message
 -v --version | return version of program

Configuration ⚙️

nitch is configured by changing the source code
