Microgrep

microgrep a simple and short scoped Rust implementation of the popular tool grep.

Usage

To look for a word match in any file, enter the following command -

microgrep essay.txt bird

To look for a word match in all the files inside a folder, enter the following command -

microgrep essayfolder bird

To use Regex (PERL flavoured Regex), you'll have to pass the --regex flag. here's an example -

microgrep essay.txt \d\w --regex

You can also mix match all these features. Here's an example -

microgrep essayfolder \d\W --regex

And as always if any of your input arguments include a space, you'll have to wrap it in quotes. Here's an example -

microgrep "my essay folder" "Rust is cool"

Development Process

Firstly ensure that you have all the Rust related toolchain installed. After that enter the directory and run cargo build. That should download and install the dependencies. After that you can start developing the tool ;)

Optional Tooling

Optionally you can install the watch tool and use it to run the compiler to compile and run your code when you save a file. To do so, run the following command -

cargo install watch

And then run the following command -

cargo watch -c -x 'run -- path search --regex'
