我非常喜欢这种缩进风格:
hash =
[ "bla" => :bla
, "bli" => :bli
, "blo" => :blo
]
但是Ruby并不那么喜欢它。
没关系:
{ 'a' => 1, 'b' => 2 }
#=> {"a"=>1, "b"=>2}
但是这个:
{ 'a' => 1
, 'b' => 2 }
产量
-:2: syntax error, unexpected ',', expecting '}'
, 'b' => 2 }
^
-:2: syntax error, unexpected =>, expecting end-of-input
, 'b' => 2 }
^
是作者想要的还是一个奇怪的错误?

您可以为每一行添加\
:
hash =
[ "bla" => :bla \
, "bli" => :bli \
, "blo" => :blo \
]
#=> [{"bla"=>:bla, "bli"=>:bli, "blo"=>:blo}]

在换行符之前移动逗号,ruby再次开心:
hash =
[ "bla" => :bla,
"bli" => :bli,
"blo" => :blo
]
#=> [{"bla"=>:bla, "bli"=>:bli, "blo"=>:blo}]
