rgrep

A demo with much more limited ability than grep. It's also one of my rust coding practices.

Effect:

• File:

• Pipe:

Features:

• Showing the line and the position of the matched words
• Can capture the output of the pipe, likeps aux | rgrep <keyword>

TODOs

• Enable range search of the file(s)
• Reconstruct the code, try to implement impl and Trait rather than lots of fn s
• Add these functions, and maybe some more:
  • Match multiple regexs
  • You can use use your own .conf to customize the content of the args
  • Async I/Os
  • Enable the file path as the arg
• Add more test cases
• Add benchmarks

Special Thanks

• imag1ne - grepr: The code make me get some idea about the trait and impl things, and it is with clear structure :)
