gitignore and extensions

[avolgha]

Hey, I like your project and tried to use it today.
After building the source, I run it in my project just to find out that there are a few problems in the source code that I want to address.

First, you require the user to have a .gitignore file in his project. If the user does not have it, the program will fail at

let gitignore = fs::read_to_string(".gitignore")?;

To solve this error, I personally changed it to this:

let gitignore = fs::read_to_string(".gitignore");
let gitignore = if gitignore.is_ok() {
   gitignore
   .unwrap()
   .lines()
   .map(|line| line.trim())
   .filter(|line| !line.starts_with('#'))
   .map(|line| line.to_string())
   .collect::<Vec<String>>()
} else {
   vec![]
};

That works fine for me because now, having a gitignore is optional.

Second, you require the user to add extensions to all files. Files with no extensions will let the program fail aswell here:

if !supported_filetypes.contains(&entry.path().extension().unwrap().to_str().unwrap()) {
//                                                         ^^ here will it fail
    continue;
}

I solved that issue by using a let Some:

if let Some(extension) = &entry.path().extension() {
    if !supported_filetypes.contains(&extension.to_str().unwrap()) {
        continue;
    }
}

That were two things I wanted to address.
Nontheless, it is a great project and I hope somebody will find this usefull

maybe someone wants to create a pull request for that...?

And just to clarify, I'm not a rust dev so my code might not be that good
