# Code Highlight
> To highlight code part, use HTML markup `<pre><code class="hljs">` and `<mark>` for highlighting
```lua
function sample()
<mark>print "Lua"</mark> # no highlight
end
```
<pre><code class="lua hljs">function sample()
print <mark>"Lua"</mark>
<mark>print "Lua"</mark>
<mark class="line"> print "Lua"</mark>

# Code Highlight
<pre><code class="hljs html raw"><pre><code class="lua hljs">function sample()

will render into
<pre><code class="lua hljs">function sample()

# Условные переменные
`fiber.cond()`
: Создание новой условной переменной
```lua
condition = fiber.cond()
```
`cond:wait()`
: Перевод файбера в режим ожидания
<div>
<pre><code>racer = function()
<span class="fragment highlight-current-red" data-fragment-index="1">condition:wait()</span>
print("Fiber "..fiber.self().id().." passed")
end
</code></pre>
</div>
Note:
- `fiber.cond()`
Создание новой условной переменной. Возвращает `cond_object`.
- `cond_object:wait([timeout])`
Перевод файбера в режим ожидания, пока другой файбер не выполнит `cond_object:signal()` или `cond_object:broadcast()` от той же переменной.
