rsopen

rsopen is a multiplatform application launcher written in Rust. It attempts to launch an application by name using the following strategy:

1. Native Launch: Uses the OS native command (e.g., open, start) if the app is in your PATH or registered.
2. Desktop Entry Search (Linux): Searches standard desktop entry locations (e.g., /usr/share/applications) for applications matching the name (exact or fuzzy) and parses the Exec command.
3. Common Path Search: Searches standard installation directories (e.g., /Applications, C:\Program Files, /usr/bin) for executables.
4. Full Search: Recursively searches the filesystem (with optimization/filtering) for the best match.

Features

• Multiplatform: Supports Windows, macOS, and Linux.
• Fuzzy Search: Uses Levenshtein distance to find the closest match if an exact name isn't found.
• Robust Searching: Filters out directories and handles complex launch commands (e.g., in .desktop files).

Usage

As a CLI

# Launch generic application
rsopen firefox

# Launch with verbose output (to see search process)
rsopen -v "Terminal"

As a Library

use rsopen::launch_app;

fn main() {
    // Launch 'firefox' with verbose=false
    if let Err(e) = launch_app("firefox", false) {
        eprintln!("Error: {}", e);
    }
}

Installation

cargo install rsopen
