## Code Blocks

Code blocks.. ❤️ with automatic syntax highlighting ✨‍

See [the docs](https://www.getzola.org/documentation/content/syntax-highlighting/) for options.

### Inline Code block

If we want, we can also `specify inline code` which is useful for `the small stuff`.

### rust
```rust
//! jelly-actix-web-starter - A starter template for actix-web projects that feels very Django-esque. Avoid the boring stuff and move faster.

use jelly::actix_web;
use mainlib;
use std::io;

#[actix_web::main]
async fn main() -> io::Result<()> {
    mainlib::main().await
}

let context = Context::new();
```

### TOML
```toml
base_url = "https://abridge.netlify.app/"
title = "Abridge"
description = "Abridge is a fast and lightweight Zola theme using semantic html, abridge.css class-light CSS, and No JS."
default_language = "en"
#theme = "abridge"

build_search_index = true
minify_html = false
feed_filename = "atom.xml"
taxonomies = [
    {name = "categories", feed = true},
    {name = "tags", feed = true},
]
```

### html
```html
<!doctype html>
<html lang="en">
<head>
  <meta charset="utf-8">
  <title>Example HTML5 Document</title>
</head>
<body>
  <!--Main Content Area-->
  <p>Test</p>
</body>
</html>
```

### javascript
```javascript
function closeSearch() {//close the search displaying the regular page.
    const e = document.querySelector("main");
    e.innerHTML = window.main
}

function goSearch() {// on enter key or search icon click display results to the page.
    const e = document.querySelector("main");
    window.main || (window.main = e.innerHTML);
    var t = document.getElementById("suggestions"),
        n = ((ResultsClone = t.cloneNode(!0)).id = "results", document.createElement("div")),
        o = '<h2><button type="button" title="Close Search" onclick="closeSearch()"><i class="svgs x"></i></button> Results For: '.concat(document.getElementById("userinput").value, "</h2>");
    return n.innerHTML = o, ResultsClone.insertBefore(n, ResultsClone.firstChild), e.innerHTML = ResultsClone.outerHTML, t.innerHTML = "", document.getElementById("userinput").value = "", !1
}! function() {
  // search function code goes here
}
```

### php
```php
<?php
/**
 * Postfix Admin
 */
require_once('common.php');
$CONF = Config::getInstance()->getAll();

if ($_SERVER['REQUEST_METHOD'] == "POST") {
    if (!isset($_SESSION['PFA_token'])) {
        die("Invalid token (session timeout; refresh the page and try again?)");
    }
    $fUsername = trim(safepost('fUsername'));
    if ($lang != check_language(false)) { # only set cookie if language selection was changed
        setcookie('lang', $lang, time() + 60*60*24*30); # language cookie, lifetime 30 days
    }
}

$_SESSION['PFA_token'] = md5(uniqid("pfa" . rand(), true));

/* vim: set expandtab softtabstop=4 tabstop=4 shiftwidth=4: */

### SQL
```sql
-- jelly-actix-web-starter - Creates an accounts table, along with some associated helpers.

create or replace function update_timestamp() returns trigger as $$
begin
    new.updated = now();
    return new;
end;
$$ language 'plpgsql';

create table if not exists accounts (
    id serial primary key,
    name text not null,
    email text not null unique,
    password text not null,
    profile jsonb not null default '{}',
    plan integer not null default 0,
    is_active boolean not null default true,
    is_admin boolean not null default false,
    has_verified_email boolean not null default false,
    last_login timestamp with time zone,
    created timestamp with time zone not null default now(),
    updated timestamp with time zone not null default now()
);

create unique index accounts_unique_lower_email_idx on accounts (lower(email));

create trigger user_updated before insert or update on accounts
for each row execute procedure update_timestamp();
```

### Lua
```lua
function square(x)
    return x * x
end

print(square(2)) -- prints '4'

function getPlayerInformation()
   playerName = UnitName("player")
   playerLevel = UnitLevel("player")
   specId, specName = GetSpecializationInfo(GetSpecialization())

   return "Hey, I'm " .. playerName .. " (Level " .. playerLevel .. "). I'm currently in spec " .. specName .. "."
end

print(getPlayerInformation())
```

### C
```c
#include <stdio.h>
int main() {
    int a;
    /* actual initialization */
    a = 10;
    printf("Hello, World!");
    return 0;
}
```

### C++
```cpp
// Your First C++ Program

#include <iostream>

int main() {
    int a;
    /* actual initialization */
    a = 10;
    std::cout << "Hello World!";
    return 0;
}
```

### Go
```go
package main

import "fmt"

func main() {
    var myvariable1 = 20
    var myvariable2 = "hello world"
    fmt.Println("hello world")
}
```
