summary: - adds prettier formatter configuration - formats the entire repo using prettier, ignoring minified files (`*.min.css`) and heavy generated html - changes extensions of all `.html` files to `.liquid`, which is more correct and necessary for prettier to work correctly - replaces "%-" and "-%" with just "%" — manual liquid formatting using minus signs is superfluous since we are compressing and minifying the code anyway - adds CI action for running prettier check on PR and pushes to master

This theme implements a built-in Jekyll feature, the use of Rouge, for syntax highlighting. It supports more than 100 languages. This example is in C++. All you have to do is wrap your code in markdown code tags:
```c++
code code code
```
int main(int argc, char const \*argv[])
{
string myString;
cout << "input a string: ";
getline(cin, myString);
int length = myString.length();
char charArray = new char * [length];
charArray = myString;
for(int i = 0; i < length; ++i){
cout << charArray[i] << " ";
}
return 0;
}
For displaying code in a list item, you have to be aware of the indentation, as stated in this Stackoverflow answer. You must indent your code by (3 * bullet_indent_level) spaces. This is because kramdown (the markdown engine used by Jekyll) indentation for the code block in lists is determined by the column number of the first non-space character after the list item marker. For example:
1. We can put fenced code blocks inside nested bullets, too.
1. Like this:
```c
printf("Hello, World!");
```
2. The key is to indent your fenced block in the same line as the first character of the line.
Which displays:
-

By default, it does not display line numbers. If you want to display line numbers for every code block, you can set kramdown.syntax_highlighter_opts.block.line_numbers to true in your _config.yml file.
If you want to display line numbers for a specific code block, all you have to do is wrap your code in a liquid tag:
{% raw %}
{% highlight c++ linenos %}
code code code
{% endhighlight %}
{% endraw %}
The keyword linenos triggers display of line numbers.
Produces something like this:
{% highlight c++ linenos %}
int main(int argc, char const *argv[]) { string myString;
cout << "input a string: ";
getline(cin, myString);
int length = myString.length();
char charArray = new char * [length];
charArray = myString;
for(int i = 0; i < length; ++i){
cout << charArray[i] << " ";
}
return 0;
}
{% endhighlight %}
