Code

This is just a test with syntax highlighting and some examples made by Rouge. It still renders wrong and I don’t know why, but I think it is my very old CSS stylesheet that should be refactored to a more modern style…

Bash

          #!/bin/bash  echo "Hello World!";        

C

          #include <stdio.h> int main() {    // printf() displays the string inside quotation    printf("Hello, World!");    return 0; }        

JSON

                       {                             "firstName"             :                           "John"             ,                             "lastName"             :                           "Smith"             ,                             "age"             :                           25                           }                               

Perl

          #!/usr/bin/env perl  use warnings; print "a: "; my $a = "foo"; print $a;        

PHP

          <?php echo "Hello World!"; ?>        

Python

          #!/usr/bin/env python  def hello(name):   print("Hello ", name)  hello("World")        

Ruby

          class Greeter   def initialize(name="World")     @name = name   end    def say_hi     puts "Hi #{@name}!"   end end        

Rust

          use core::*;  fn main() {     for ["Alice", "Bob", "Carol"].each |&name| {         do task::spawn {             let v = rand::Rng().shuffle([1, 2, 3]);             for v.each |&num| {                 io::print(fmt!("%s says: '%d'\n", name, num))             }         }     } }        

SQL

          SELECT * FROM `users` WHERE `user`.`id` = 1        

Graphviz

I am testing Grapphviz diagrams here… For now it seems stable and ready to use…
