Minigrep

I like to learn new languages by re-implementation of tools and commands that I use on a daily basis.

grep is a useful command tool for finding substrings within a string in Unix-like operating systems.

With minigrep we will read a file and return lines which contain specific string (passed as arguments) in that file.

The functionnalities will be developed in TDD.

Run

cargo run -- "j'ai vu" Rimbaud.txt

Or

IGNORE_CASE=1 cargo run -- "j'ai vu" Rimbaud.txt

TODO

• Read a file
• Search for specific lines passed as argument
• Sensitive and insensitive query
• Allow user to configure sensitivity via environment variable
• Write errors to `stderr
