# C++ Code Cruncher (compactor)

![screenshot2](https://github.com/lostjared/Code.Crunch.JavaScript/blob/main/crunch.jpg)

This project is a simple web-based tool to "crunch" C++ code by removing 

unnecessary whitespace and comments while preserving the code's 

functionality. It processes input C++ code and outputs a more compact 

version. I got this working for most C++ code. I am not going to work on this anymore

as I used this to create some videos and now am moving on.

## Motivation

I wanted to make a video with scrolling compacted C++ code so I wrote this to accomplish that.

I thought others might find it useful so I posted it here.

## Features

- Preserves preprocesscor directives.

- Removes multiline and single line comments.

- Preserves single character constants and string literals.

- Eliminates unnecessary whitespace, including double spaces and unrequired space between operaators.

- Skips empty lines and space characters before comments.

## Known Issues

- when you have // within a string under certain conditions it will cause the text to be unaligned

- does not work with most other languages

- raw strings as of now are unsupported.

if you want to fix these issues fork and submit a pull request!

## Usage

1. Open the `index.html` file in your web browser.

2. Enter your C++ code in the provided textarea.

3. Click the "Crunch" button.

4. View the processed code in the output section.

## Code Explanation

The main functionality is provided by the JavaScript code within the 

`index.html` file:

- **crunch(input)**: Main function that processes the input text, removing 

comments and crunching lines.

- **removeMlComment(text)**: Helper function to remove multiline comments.

- **chkChr(text, i, c)**: Helper function to check if a character matches 

a specified character.

- **crunchLine(s)**: Function to process each line, handling string 

literals, character constants, and removing unnecessary characters.

- **testchr(s, i)**: Helper function to test for characters that should be 

removed.

- **crunchText()**: Function to get input from the textarea, process it, 

and display the output.

## Example

Input:

```cpp

#include 

int main() {

    // This is a single line comment

    std::cout << "Hello, World!" << std::endl;  /* This is a

    multiline comment */

    char c = '\\';

    return 0;

}

```

Output:

```cpp

#include 

int main(){std::cout <<"Hello, World!"<
