render タグのフォーマッティングテスト

It should never break a name
printWidth: 1
{% render block %}
{%- render "snippet" -%}

It should not break aliases if there's no variable (obscure syntax)
printWidth: 1
{% render "foo/bar" as foo %}

It should not break on variable expression alone
printWidth: 1
{% render "foo" with foo %}

It should break on variable expression + alias
printWidth: 1
{% render "foo" with foo as bar %}

It should break on alias + args (after alias)
printWidth: 1
{% render "foo/bar" as bar, key1: val1, key2: (0..1) %}

It should break on variable + args (after variable)
printWidth: 1
{% render "foo/bar" with "string", key1: val1, key2: (0..1) %}

It should break on variable + alias + args (before variable)
printWidth: 1
{% render "foo/bar" with "string" as bar, key1: val1, key2: (0..1) %}

It should break on named args
printWidth: 1
{% render "foo/bar", key1: val1, key2: (0..1) %}

It should not require commas (as per syntax) but add them when pretty printed
{% render "foo/bar" key1: val1 key2: (0..1) %}

It should not require spaces (as per syntax) but add them when pretty printed
{%render "foo/bar",key1:val1,key2:(0..1)%}

It should strip trailing commas by default
{% render "foo", %}
{% render "foo",product:product, %}
{% render "foo" with foo as bar, %}
