minigrep

This is a command line program that implements the minigrep project from the Rust book.

Functionality:

• Parse text files into lines
• Find and print lines that contain the query argument from command line
• Supports case-insensitive search via environment variable

Running this program

You can run unit tests on this via:

cargo test

You can run the program via the following syntax:

cargo run [query text] [text file]

For example,

cargo run frog poem.txt

Note that poem.txt is included in this project.

Case-insensitive Search

If you're using PowerShell, you can use the environment variable via the following:

PS> $Env:CASE_INSENSITIVE=1; cargo run [query text] [text file]

Since the variable will persist for the remainder of the shell session, you can unset it via the following:

PS> Remove-Item Env:CASE_INSENSITIVE
