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