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:

#

````markdown

```c++

code code code

```

````

#

```c++

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 FAQ. 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:

#

````markdown

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:

#

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.

#

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:

# #

{% highlight c++ linenos %}
code code code
{% endhighlight %}

# #

The keyword linenos triggers display of line numbers.

Produces something like this:
