Syntax Highlighter

Koala includes our ‘Ecko Blocks’ plugin, which introduces additional features to the Code core Gutenberg block. These features include language-specific syntax highlighting, multiple color schemes, line numbers, and support for popular languages (a complete list can be found below).

Color Schemes

// This is an example of the 'Light' color scheme

function wp_get_time(){
    if(get_theme_mod('layout_use_custom_date_format', false)){
        the_date();
    }else{
        the_time('jS F Y ');
    }
}

// This is an example of the 'Dark' color scheme.

function wp_get_time(){
    if(get_theme_mod('layout_use_custom_date_format', false)){
        the_date();
    }else{
        the_time('jS F Y ');
    }
}

// This is an example of the 'High Contrast' color scheme.

function wp_get_time(){
    if(get_theme_mod('layout_use_custom_date_format', false)){
        the_date();
    }else{
        the_time('jS F Y ');
    }
}

Line Numbers

If you wish to display line numbers along with a Code block this can be enabled via the included options. Below is an example Code block using line numbers with the Dark color scheme.

const http = require('http');

const hostname = '127.0.0.1';
const port = 3000;

const server = http.createServer((req, res) => {
  res.statusCode = 200;
  res.setHeader('Content-Type', 'text/plain');
  res.end('Hello World\n');
});

server.listen(port, hostname, () => {
  console.log(`Server running at http://${hostname}:${port}/`);
});
