Nitch

A lightning-fast system fetch utility written in Nim that displays your system information alongside a customizable logo in the terminal. Optimized for performance without any dependencies.

Features

• Customizable: Easy to modify and extend
• Cross-platform: Works on most Unix-like systems
• Lightning fast: Compiled with maximum optimizations
• Low memory footprint: Minimal resource usage
• No external dependencies: Standalone binary

Installation

Prerequisites

• Nim (version 2.2.6 or higher)

Using Nimble

This will automatically compile and install the binary.

nimble install https://github.com/gabrielcapilla/nitch.git

Manual installation

git clone https://github.com/gabrielcapilla/nitch.git
cd nitch

Build with hard speed optimizations.

nimble release

Install the binary in your local installation directory

mv nitch $HOME/.local/bin

Usage

nitch

Flags

 -f --fetch   | return fetch about system
 -n --nologo  | return fetch without logo
 -h --help    | return help message
 -v --version | return version of program

Build commands

Command	Description
nimble release	Build with hard speed optimizations (recommended)
nimble benchmark	Run performance benchmark and keep the fastest binary

Performance Benchmark

Nitch includes an automated benchmark tool that measures execution speed of different compilation variants and automatically keeps the fastest one:

nimble benchmark

This will:

1. Compile all 3 variants (debug, standard, optimized)
2. Run performance tests on each
3. Identify the fastest variant
4. Automatically remove slower variants
5. Keep only the fastest binary

Running benchmark

Variant               | Total Time  | Average     | Min         | Max
----------------------|-------------|-------------|-------------|-----------
Debug                 |   0.392411s |   7848.22μs |   7642.60μs |   8293.32μs
Standard (-d:release) |   0.101966s |   2039.31μs |   1942.88μs |   2226.64μs
Optimized (Custom)    |   0.095052s |   1901.04μs |   1842.65μs |   2010.93μs

Fastest variant: optimized (avg: 1901.04μs)
Slowest variant: debug (avg: 7848.22μs)
Improvement: 412.84% faster

Binary sizes:
debug     :  373712 bytes
standard  :  207728 bytes
optimized :  105032 bytes

System optimization...
Cleaning up...
  - Removed: nitch_debug
  - Removed: nitch_standard
  - Kept: nitch (renamed from nitch_optimized)

Done! The 'nitch' binary is now the fastest version.
