🔍 Troubleshooting Guide

Common Issues and Solutions

Issue: Binary not found after installation

# Check if binary exists
ls -la /usr/local/bin/neofetch

# Check PATH
echo $PATH

# Add to PATH if needed
export PATH="/usr/local/bin:$PATH"
echo 'export PATH="/usr/local/bin:$PATH"' >> ~/.bashrc

Issue: Permission denied

# Make binary executable
chmod +x /usr/local/bin/neofetch

# Or reinstall with proper permissions
sudo make install

Issue: Build fails

# Update Rust toolchain
rustup update

# Clean and rebuild
make clean
make release

# Check Rust version (requires 1.70+)
rustc --version

Issue: Missing system information

# Run with verbose output for debugging
neofetch --verbose

# Check if specific tools are installed
which lscpu    # Linux CPU info
which sw_vers  # macOS system info
which wmic     # Windows system info

Debug Mode

# Build debug version
make build

# Run with debug logging
RUST_LOG=debug ./target/debug/neofetch --verbose

# Trace all system calls
RUST_LOG=trace ./target/debug/neofetch 2> debug.log

📊 Performance Guide

Benchmarking

# Time the execution
time neofetch

# Compare with original neofetch

FAQ

General Questions

Q: How is this different from the original neofetch? A: Neofetch-rs is written in Rust for better performance, smaller memory footprint, and cross-platform compatibility. It's ~4x faster and uses ~75% less memory than the original.

Q: Can I use my existing neofetch config? A: Not directly. Neofetch-rs uses TOML configuration instead of bash scripts. However, most options have equivalent settings.

Q: Does this replace the original neofetch? A: It can! The binary is named neofetch and supports most of the same command-line options.

Q: Why is the binary so much smaller? A: The release build uses aggressive optimizations including LTO, symbol stripping, and maximum optimization levels.

Technical Questions

Q: What Rust version is required? A: Rust 1.70 or later is required for compilation.

Q: Can I cross-compile for different platforms? A: Yes! Use cargo build --target <target-triple> for cross-compilation.

Q: How do I contribute new features? A: See the Development Guide above and check the CONTRIBUTING.md file.

Q: Is Windows support complete? A: Basic Windows support is implemented, but some features may be limited compared to Unix systems.
