rwc

This is just a simple version of GNU/wc command clone, written in Rust.
For rust beginners, feel free to look this project for practice :)

(Using Clap-v4)

Features

What I had archived are as follows:

  • Support for reading multiple files and calculating the result in parrllel
  • Pretty tabled output
  • Colorful progress bar for reading files (It is useful when reading large file)
  • Completions for common shells (Look here for more information)

Note:
It is super faster and prettier than wc command when reading a large of big files. (Thanks to rayon)
To put it another word, it is slower when reading a small numbers of small files.

For the Chinese, you could view my blog about using clap-rs to write this project
