README
[](https://app.codecrafters.io/users/codecrafters-bot?r=2qF)
This is a starting point for Rust solutions to the
["Build Your Own grep" Challenge](https://app.codecrafters.io/courses/grep/overview).
[Regular expressions](https://en.wikipedia.org/wiki/Regular_expression)
(Regexes, for short) are patterns used to match character combinations in
strings. [`grep`](https://en.wikipedia.org/wiki/Grep) is a CLI tool for
searching using Regexes.
In this challenge you'll build your own implementation of `grep`. Along the way
we'll learn about Regex syntax, how parsers/lexers work, and how regular
expressions are evaluated.
**Note**: If you're viewing this repo on GitHub, head over to
[codecrafters.io](https://codecrafters.io) to try the challenge.
# Passing the first stage
The entry point for your `grep` implementation is in `src/main.rs`. Study and
uncomment the relevant code, and push your changes to pass the first stage:
```sh
git commit -am "pass 1st stage" # any msg
git push origin master
```
Time to move on to the next stage!
# Stage 2 & beyond
Note: This section is for stages 2 and beyond.
1. Ensure you have `cargo (1.82)` installed locally
1. Run `./your_program.sh` to run your program, which is implemented in
`src/main.rs`. This command compiles your Rust project, so it might be slow
the first time you run it. Subsequent runs will be fast.
1. Commit your changes and run `git push origin master` to submit your solution
to CodeCrafters. Test output will be streamed to your terminal.
