Neo-cowsay
A fast, extended Go rewrite of the classic cowsay command-line tool with new features and library support.
What is Neo-cowsay?
Neo Cowsay is a modern rewrite of the classic cowsay command-line tool, implemented in Go with extended features and library support. It generates ASCII art cows with speech bubbles containing user-provided text, offering improved performance and additional functionality over the original Perl version.
Developers and system administrators who enjoy command-line utilities, ASCII art enthusiasts, and Go developers looking for a fun library to integrate ASCII art generation into their applications.
Neo Cowsay provides a faster, more feature-rich alternative to the original cowsay with UTF-8 support, additional cowfiles, visual effects, and the ability to be used both as a command-line tool and as a Go library for programmatic integration.
Overview
🐮 cowsay is reborn. Neo Cowsay has written in Go.
Use Cases
Best For
- Adding ASCII art cows to command-line scripts and outputs
- Generating fun terminal messages for development environments
- Integrating ASCII art generation into Go applications
- Creating visual terminal greetings or system messages
- Teaching command-line tool concepts with a fun example
- Enhancing GitHub Actions workflows with visual feedback
Not Ideal For
- Production environments requiring minimal binary size, as Go executables can be larger than Perl scripts.
- Teams relying on exact compatibility with original cowsay Perl scripts or community cowfiles not ported to Neo-cowsay.
- Projects needing rich graphical output beyond terminal-based ASCII art.
- Formal documentation or presentations where playful ASCII art is inappropriate.
Pros & Cons
Pros
Written in Go, Neo Cowsay executes faster than the original Perl version, making it ideal for frequent ASCII art generation in scripts.
Adds modern options like random cow selection, a fuzzy finder for cowfiles, and coloring filters, enhancing usability beyond the basic tool.
Properly handles international characters and symbols, allowing for diverse text in speech bubbles, as highlighted in the README.
Can be imported as a Go library for programmatic ASCII art generation, with examples provided in the documentation.
Includes super mode and effects like rainbow coloring, adding playful visual flair to terminal outputs.
Cons
Setup varies by platform and requires specific package managers like Homebrew or Scoop, which may not be available in all environments, unlike the original's simpler Perl dependency.
While it adds new cowfiles, the selection is smaller compared to the extensive community-contributed cowfiles for the original cowsay, limiting customization.
As a reimplementation, it may not support all legacy options or scripts from the original cowsay, requiring adjustments for existing workflows.
