PrettyHash

PrettyPrint the Hash

Format to the ascii table format for Hash. It's very small library.

Add this line to your application's Gemfile:

gem 'pretty_hash'

And then execute:

$ bundle

Or install it yourself as:

$ gem install pretty_hash

require 'pretty_hash'
puts {"a" => "abcde", "bbb" =>  "a"}.to_pp_table

---|-----
  a|abcde
bbb|a
---|-----

{:ccc => "aa", "dddd" => "a"}.to_pp_table

----|--
:ccc|aa
dddd|a
----|--

v1 = Struct.new(:name).new("foo")
v1.name
=> "foo"
v2 = Struct.new(:name).new("bar")
v2.name
=> "bar"

{:k1 => v1, :k2 => v2}.to_pp_table

---|---------------------
:k1|#<struct name="hoge">
:k2|#<struct name="foo">
---|---------------------

Too bad....

{:k1 => v1, :k2 => v2}.to_pp_table(Proc.new{|c|c.name})

---|----
:k1|hoge
:k2|foo
---|----

Good!

{:ccc => "日本語講座", "dddd" => "a"}.to_pp_table

----|----------
:ccc|日本語講座
dddd|a
----|----------

Just fit width.

• Nested value (e.g.) { a: => {:v1 => 1 }}
