# RRD

[**R**ick **R**oll](https://www.youtube.com/watch?v=dQw4w9WgXcQ "Rickrolling - Wikipedia") **D**etector

### Why

I wanted to learn C++. I already know the syntax (mostly) and I wanted to test myself with using C++ and external libraries

#### Why not Python

The entire program can be written in **1 line of Python**:

```python

import re,urllib.request,sys;print("Usage: rrd URL" if len(sys.argv) < 2 else "Possible rickroll detected" (if re.search(r"((rick\s*roll)|(never\s*gonna\s*(give\s*you\s*up)?)|(dQw4w9WgXcQ))", urllib.request.urlopen(sys.argv[1]).read().decode()) else "No rickroll detected"));sys.exit(1 if len(sys.argv) < 2 else 0)

```

or 4 lines, conforming very closely to my C++ program

```python

import re, urllib.request, sys

REGEX = re.compile(r"((rick\s*roll)|(never\s*gonna\s*(give\s*you\s*up)?)|(dQw4w9WgXcQ))")

if len(sys.argv) < 2:

    print("Usage: rrd URL")

    sys.exit(1)

with urllib.request.urlopen(sys.argv[1]) as f:

    print(

        "Possible rickroll detected"

        if REGEX.search(f.read().decode())

        else "No rickroll detected"

    )

```

But come on, that defeats the purpose of this project.

### Installation

1. Download source

```bash

git clone https://github.com/ThatXliner/rrd.git

cd rrd

```

2. Generate makefiles

```bash

cmake .

```

[*Hey it fails!*](#troubleshooting)

3. Build the program

```bash

make

```

4. Enjoy

```bash

./rrd 'https://www.youtube.com/watch?v=dQw4w9WgXcQ'

```

(or, on Windows)

```powershell

.\rrd 'https://www.youtube.com/watch?v=dQw4w9WgXcQ'

```

### Help

#### Troubleshooting

**Running `cmake .` doesn't work!**

This part took me a TON of time.

If you're on Mac and have [homebrew](https://brew.sh) (and you can run it), run

```bash

brew upgrade

brew update

brew install openssl

```

Should fix your problems. I forgot what worked for me but at some point, re-installing OpenSSL was all that I needed.
