Twig ternary operator, Shorthand if-then-else

Does Twig support ternary (shorthand if-else) operator?

I need some conditional logic like:

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

but using shorthand in Twig.

{{ (ability.id in company_abilities) ? 'selected' : '' }}

The ternary operator is documented under 'other operators'

You can use shorthand syntax as of Twig 1.12.0

{{ foo ?: 'no' }} is the same as {{ foo ? foo : 'no' }}
{{ foo ? 'yes' }} is the same as {{ foo ? 'yes' : '' }}

Support for the extended ternary operator was added in Twig 1.12.0.

1. If foo echo yes else echo no:

    {{ foo ? 'yes' : 'no' }}
   

2. If foo echo it, else echo no:

    {{ foo ?: 'no' }}
   

or

    {{ foo ? foo : 'no' }}

3. If foo echo yes else echo nothing:

    {{ foo ? 'yes' }}

or

    {{ foo ? 'yes' : '' }}

4. Returns the value of foo if it is defined and not null, no otherwise:

    {{ foo ?? 'no' }}

5. Returns the value of foo if it is defined (empty values also count), no otherwise:

    {{ foo|default('no') }}

If the price exists from the database for example then print (Price is $$$) else print (Not Available) and ~ for the concatenation in Twig.

{{ Price is defined ? 'Price is '~Price : 'Not Available' }}

I just used a as a general variable name. You can also use endless if else like this:

{{ a == 1 ? 'first' : a == 2 ? 'second' : 'third' }}
