Question

I m getting input from a user using Ruby s Highline gem. I m asking the following

note = ask("Enter a note for this entry: ")

This is fine, but If the user edits the entry I want to populate the prompt with their existing answer for this question so that it can be edited directly instead of entering it again.

类似:

note = ask("Enter a note for this entry: ", :current => note)

# Output:    
Enter a note for this entry: the current note_

Answer 1

A little bit too late, but:

The best solution i found for this problem was to use the completion attribute in the ask block.
So when you write the following code:

input = "Foobar" #default
loop do
    input = ask("Input: ") { |q| q.completion = [input]; q.readline = true }
end

你们最后要这样做。

Input: Fo<hit tab>
Input: Foobar

每次更新<代码>completion 因此,你可以很容易地从您的最后一行获得投入。

Answer 2

我从未使用过高线,但申请方法的文件表明,它是一种选择性的屏障。我认为,这是你如何做的:

note = ask("Enter a note for this entry: ") { |q| q.default = "Default Answer" }
