twig-ast's Issues

Doesn’t handle single quotes

When using double quotes, code passes:

{% if foo("bar") %}{% endif %}

But using single quotes, code fails:

{% if foo('bar') %}{% endif %}

Doesn’t support `set`

When trying to parse following code:

{% set variable = app.get('variable') %}

Following error is thrown:

Error: Failed to parse template in state TAG_CONTROL at position 16: "{% set variable *= app.get('variable') %}\n"

set is an official Twig element.
