Question

我有一个对象，我希望查看所有属性，但使用probe打印出我无法读取的页面和信息页面，并使用mold仅打印出第一个位。

>> mold input
== {make object! [
    type: 'face
    offset: 20x20
    size: 400x150
    span: none
    pane: none
    text: "Text"
    color: 25...

Answer 1

我习惯在对象上使用help，如

>> help system
SYSTEM is an object of value:
   version         tuple!    2.7.8.3.1
   build           date!     1-Jan-2011/16:39:07-8:00
   product         word!     View

而不是第一个对象，您现在应该使用 words-of

>> help words-of
USAGE:
    WORDS-OF value

DESCRIPTION:
     Returns a copy of the words of a function or object.
     WORDS-OF is a function value.

ARGUMENTS:
     value -- (Type: any)
>> probe words-of system
== [version build product core components words license options user script console ports network schemes error standard view
   stats locale user-license]

Answer 2

您可以使用first获取对象的所有属性，>> ? first USAGE: FIRST series DESCRIPTION: Returns the first value of a series. FIRST is an action value. ARGUMENTS: series -- (Type: series pair event money date object port time tuple any-function library struct event)可以处理大量类型，包括对象。传递对象时，它返回表示属性的单词列表。

first input

所以在我的例子中，>> probe first input [self type offset size span pane text color image effect data edge font para feel saved-area rate show? options parent-face old-offset old-size line-list changes face-flags action state access style alt-action facets related words colors texts images file var keycode reset styles init multi blinker pane-size dirty? help user-data flag s doc]给出了以下内容：
