liquid タグの整形・フォーマット

<div>
{%
  liquid
  assign x = 1
  assign y = 2
  if A
    assign z = 1
  endif
%}
</div>
<div>
{%- liquid
  assign x = 1
  assign y = 2
  if A
    assign z = 1
  endif -%}
</div>

It should reindent and format
{%- liquid
  if empty   and   true
render 'icon-cart-empty'
      else
  render 'icon-cart'
      endif
-%}

It should handle comments correctly
{%- liquid
comment
how u doin?
endcomment -%}

It should handle nested comments correctly
{%- liquid
comment
how u doin?
comment
  ho
endcomment
endcomment -%}

It should handle empty nested comments correctly
{%- liquid
comment
how u doin?
comment
endcomment
endcomment -%}

It should handle inline comments correctly
{%- liquid
# heyy how u doin
# not too bad
  #
# you? -%}

It should pretty print #### lines without a space
{%- liquid
#############
#     fancy
#############
-%}

It should keep at most one empty new line between statements, and strip trailing
{% liquid
# some reason
if cond

      echo foo


      echo bar

else
echo bar
endif


# some other block
case foo
when bar,baz
echo 'hi'

else
echo 'no'
endcase

%}

It should parse tags properly and print them properly
printWidth: 1
{% liquid
assign x = thing['property']|filter1|fitler2
echo x |filter1|  filter2
capture var
  if nil
  echo true
  else
  echo false
  endif
endcapture
cycle 'one', 'two', 'three'

for x in col reversed limit:10
echo x
else
echo 'nope'
endfor

form 'cart', cart
  echo 'huh?'
endform

increment i
section 'string'
layout 'string'

paginate col by 10 window_size:50
render 'icon' with x as bar foo:bar
endpaginate
%}

It should keep newlines between tags
{% liquid
  # comment 1

  # comment 2
  if cond
    echo foo

    echo bar
  endif
%}

It should keep leading whitespace in comments
{% liquid
# This list should not be reindented:
#   - a
#   - b
#      - d
#   - c
%}

It should not freak out on variable output characters inside conditions
{% liquid
if shop.foo contains '{{cond}}'
echo 'xxx'
endif
%}
