An I/O PRoject: Building a Command Line Program1
To run the program:
$ cargo run --bin cli-program <QUERY> <FILE_PATH>
Compiling cli-program v0.1.0 ...To run the tests:
$ cargo test --package cli-program --lib -- tests --nocapture
running X testsThis project is a recreation of the command-line tool, grep (globally
search a regular expression and print). It takes as arguments:
- a file path
- a string
... then it reads the file, finds files that contain the string, and prints those lines.
This project will use:
stderrandstdout- organizing code
- vectors and strings
- handling errors
- using traits and lifetimes

... and briefly introduce closures, iterators, and trait objects.
