Ruby Readline.completion_append_character =用法及代碼示例

completion_append_character = char

指定完成時要附加的字符。如果指定了空字符串 (“”) 或 nil，則不會附加任何內容。

例如：

require "readline"

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

結果：

>
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：隻能指定一個字符。指定“string” 時，僅設置第一個“s”。

require "readline"

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

如果使用 readline 庫不支持，則引發 NotImplementedError 。
