Features

• Neovim Highlighting: Uses Neovim's syntax engine and your active MEOW_THEME or system colorscheme.
• Parallel Processing: Multithreaded rendering for high performance.
• Built-in Pager: Interactive TUI pager for files that exceed terminal height.
• Raw Streaming: cat-equivalent speed for binary files and devices (e.g., /dev/input/mice).
• Fast Mode: Automatically skips highlighting for large files to eliminate latency.

Installation

NixOS / Home Manager (Flake)

Add meow to your flake.nix inputs:

inputs.meow.url = "github:datsfilipe/meow";

Then add it to your system packages:

environment.systemPackages = [
  inputs.meow.packages.${pkgs.system}.default
];

Cargo

cargo install rmeow

Usage

# standard highlight (uses Neovim)
meow src/main.rs

# multiple files (parallel processing)
meow src/*.rs

# force highlighting on large files (bypass fast path)
meow -f assets/huge_file.lua

# raw device streaming (zero overhead)
meow /dev/input/mice

Benchmarks

1. Syntax Highlighting (Large File)

2. Standard Printing (Fast Path)

3. Raw Throughput (Streaming /dev/input/mice for 5 seconds)
