[![progress-banner](https://backend.codecrafters.io/progress/grep/31b3d3b0-abb1-4f8b-a133-a5b807254940)](https://app.codecrafters.io/users/codecrafters-bot?r=2qF)

This is a starting point for Go 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 `cmd/mygrep/main.go`. Study

and uncomment the relevant code, and push your changes to pass the first stage:

```sh

git add .

git commit -m "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 `go (1.19)` installed locally

1. Run `./your_program.sh` to run your program, which is implemented in

   `cmd/mygrep/main.go`.

1. Commit your changes and run `git push origin master` to submit your solution

   to CodeCrafters. Test output will be streamed to your terminal.
