如何在jshell中的/ set truncation命令中使用选择器?

问题描述 投票:3回答:1

我正在使用jshell并希望截断jshell控制台上显示的非常大的消息。

为此,我得到了/ set truncate命令,其中说:

如果值太长,则在显示时会截断它们。使用/ set truncation命令设置为值显示的最大长度。如果未使用该命令输入任何设置,则显示当前设置。

以下是截断的相关选择器类型。

|  
|  The case selector kind describes the kind of snippet.  The values are:
|   vardecl    -- variable declaration without init
|   varinit    -- variable declaration with init
|   expression -- expression -- note: {name}==scratch-variable-name
|   varvalue   -- variable value expression
|   assignment -- assign variable
|  The action selector kind describes what happened to the snippet.  The values are:
|   added     -- snippet has been added
|   modified  -- an existing snippet has been modified
|   replaced  -- an existing snippet has been replaced with a new snippet

任何人都可以建议案例选择器或动作选择器的用例??
