Ruby Readline.completion_append_character =用法及代码示例

completion_append_character = char

指定完成时要附加的字符。如果指定了空字符串 (“”) 或 nil，则不会附加任何内容。

例如：

require "readline"

Readline.readline("> ", true)
Readline.completion_append_character = " "

结果：

>
Input "/var/li".

> /var/li
Press TAB key.

> /var/lib
Completes "b" and appends " ". So, you can continuously input "/usr".

> /var/lib /usr

注意：只能指定一个字符。指定“string” 时，仅设置第一个“s”。

require "readline"

Readline.completion_append_character = "string"
p Readline.completion_append_character # => "s"

如果使用 readline 库不支持，则引发 NotImplementedError 。
