🦀 willfetch

A high-performance, terminal-based digital business card for the modern engineer.

willfetch is a CLI tool written in Rust that provides a "fetch-style" summary of my professional identity. It combines custom ASCII art with a stylized data presentation layer, allowing anyone to view my bio, tech stack, and socials directly from their terminal with zero latency.


📖 Why Willfetch?

The Problem

Traditional resumes and LinkedIn profiles often lack the technical personality that resonates within engineering-centric environments. I wanted a way to present my professional bio and tech stack directly in the environment where I spend most of my time: the terminal.

The Solution

By leveraging Rust, I created a "zero-cost" digital identity card. Unlike a website, it requires no browser overhead. Unlike a PDF, it is interactive and accessible via a single command.

Key Engineering Decisions

  • Buffer Merging: The custom CardRenderer implements a line-by-line iterator that merges the ASCII art buffer with the text buffer. This ensures perfect horizontal alignment regardless of the terminal's font scaling.
  • Static Lifetimes: By using &'static str for all data, the binary size remains tiny and memory allocation is handled entirely at compile-time for instantaneous rendering.
  • Semantic UX: Using the colored crate, I implemented a specific color-coding system (Cyan for identity, Yellow for titles, Magenta for socials) to ensure high scannability.

🚀 Installation Guide

You can install willfetch using several methods depending on your environment.

If you have the Rust toolchain installed, you can install and run willfetch globally in seconds:

# Install from crates.io
cargo install willfetch

# Run it anywhere
willfetch

2. Build from Source

If you want to customize the bio or explore the source code:

# Clone the repository
git clone https://github.com/wmouton/willfetch.git
cd willfetch

# Build and run immediately
cargo run

# Install your local build globally
cargo install --path .

🧬 Data Structure

The tool is built around a strictly typed schema, ensuring that my professional data is validated at build time:

struct Bio {
    name: &'static str,
    title: &'static str,
    preference: &'static str, // Remote/On-site
    available_for_hire: bool,
    socials: Socials,
    stack: &'static str,
    skills: &'static [&'static str],
}
