二郎打印整個數據結構

繼a little riak book 41，我試圖使用這些命令傾倒了環狀結構頁面上的說明：二郎打印整個數據結構

{ok,Ring} = riak_core_ring_manager:get_my_ring(). 
riak_core_ring:chash(Ring).

它的工作原理，但數據被省略。前24個條目打印正確，但其餘的只是用橢圓替換...;見下文。

如何打印完整的戒指結構？

如果您在shell中，則可以使用rp(Term)打印任意術語而不截斷。

這很好，謝謝！ –

謝謝，這工作：'RingDetails = riak_core_ring：chash（Ring）.'然後'rp（RingDetails）.' – andrewdotn

這是一個控制檯美麗的打印機截斷輸出。所有你需要的是用普通的io:format("~p~n", [Ring]).打印這個值。

如果環足夠大，'〜p'美麗的打印機也會截斷。 '〜P'會讓你在截斷之前增加深度。 – Joe
