crabsay

crabsay is a version of the unix utility cowsay that displays an ASCII representaion of Ferris, the Rust mascot instead of the usual cow. crabsay implements two key features of cowsay: accepting input from stdin, piped in from other unix utilities, and also accepting text provided as arguments.

Examples

Message piped in from stdin

bash-3.2$ fortune | crabsay
------------------------------------------
| Knebel's Law:

              \
               \
                  _~^~^~_
              \) /  o o  \ (/
                '_   -   _'
                / '-----' \

Message supplied as arguments

bash-3.2$ crabsay Hello World
------------------------------------------
| Hello World

                  _~^~^~_
              \) /  o o  \ (/
                '_   -   _'
                / '-----' \

Future Improvements

• Implement Proper Text Wrapping, right border
• Add variable width
• Use clap to handle command line parsing
• Add proper error handling
• Add other configuration
• Clean up and distribute a release

Inspired by https://github.com/mgattozzi/ferris-says

I loved the concept and decided to try to write crabsay as a learning experience. I noticed ferris-says' fsays binary does not accept arguments. my initial attempt at crabsay implements both input by arguments and piping from stdin I would like to see if clap can be used instead of using just std::env

bash-3.2$ ./fsays hello world
error: Found argument 'hello' which wasn't expected, or isn't valid in this context

USAGE:
    fsays [OPTIONS]
