Ternary operators in Twig php

Is it possible to use ternary operators in twig template? Now, for adding some class to DOM element depend on some condition I do like this:

{%if ability.id in company_abilities%}
    <tr class="selected">

    <tr>
{%endif%}

Instead of

<tr class="<?=in_array($ability->id, $company_abilities) ? 'selected' : ''?>">

in native php template engine.

PhpStorm wrap/surround selection?

Often in coding and templating i need to wrap a certain part of text. Is there any shortcut to wrap the current selection, for example:

Hello World
"Hello World"

Hello World
{{ trans 'Hello World' }}

Im using PhpStorm 7 for Mac and PC. I found something similiar, with: ctrl+alt+j you can wrap with a html-tag but nothing else. Also ctrl+alt+- comments the current selection according to the current file format(php, twig, html, ...)

Twig: in_array or similar possible within if statement?

I am using Twig as templating engine and I am really loving it. However, now I have run in a situation which definitely mustbe accomplishable in a simpler way than I have found.

What I have right now is this:

{% for myVar in someArray %}    
    {% set found = 0 %}
    {% for id, data in someOtherArray %}
        {% if id == myVar %}
            {{ myVar }} exists within someOtherArray.
            {% set found = 1 %} 
        {% endif %}
    {% endfor %}

    {% if found == 0 %}
        {{ myVar }} doesn't exist within someOtherArray.
    {% endif %}
{% endfor %}

What I am looking for is something more like this:

{% for myVar in someArray %}    
    {% if myVar is in_array(array_keys(someOtherArray)) %}
       {{ myVar }} exists within someOtherArray.
    {% else %}
       {{ myVar }} doesn't exist within someOtherArray.
    {% endif %}
{% endfor %}

Is there a way to accomplish this which I haven't seen yet?

If I need to create my own extension, how can I access myVar within the test function?

Thanks for your help!

twig: IF with multiple conditions

It seem I have problem with a twig if statement.

{%if fields | length > 0 || trans_fields | length > 0 -%}

The error is:

Unexpected token "punctuation" of value "|" ("name" expected) in 

I can't understand why this doesn't work, it's like if twig was lost with all the pipes.

I've tried this :

{% set count1 = fields | length %}
{% set count2 = trans_fields | length %}
{%if count1 > 0 || count2 > 0 -%}

but the if also fail.

Then tried this:

{% set count1 = fields | length > 0 %}
{% set count2 = trans_fields | length > 0 %}
{%if count1 || count2 -%}

And it still doesn't work, same error every time ...

So... that lead me to a really simple question: does Twig support multiple conditions IF ?
