How to exit out of a selection process?

[jasperdunn]

const responses = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10].map((item) => {
  return createSelection(
    [
      {
        text: 'skip',
      },
      {
        text: 'higher',
      },
      {
        text: 'lower',
      },
    ],
    {
      headerText: `What should be done with number: ${item}?`,
    }
  )
})

console.log(responses)

If I enter the command [CTRL] + [C], it doesn't exit the running process as expected. Instead, it continues throughout the list of items.

You're iterating through the array of numbers and printing the prompt for each number. You have 10 numbers in it, so hitting ctrl + c 10 times would exit out of the program.

Here's what it looks like with just 3 numbers in the array.

import { createSelection } from 'bun-promptx'

const responses = [1, 2, 3].map((item) => {
    return createSelection(
      [
        {
          text: 'skip',
        },
        {
          text: 'higher',
        },
        {
          text: 'lower',
        },
      ],
      {
        headerText: `What should be done with number: ${item}?`,
      }
    )
  })
  
  console.log(responses)

Thanks, is there a way to exit out of all of them though?

I have never seen the selection prompt used like this, but I suppose you could do the following:

import { createSelection } from 'bun-promptx'

[1, 2, 3, 4].map((item) => {

    const selection = createSelection(
        [
          {
            text: 'skip',
          },
          {
            text: 'higher',
          },
          {
            text: 'lower',
          },
          {
            text: 'exit',
          },
        ],
        {
          headerText: `What should be done with number: ${item}?`,
        }
    )

    if (selection.selectedIndex === 3) {
        console.log(selection)
        process.exit(0);
    }

    console.log(selection)
})

You don't ctrl + c to exit this, but instead pick the exit option. I'm more partial to using createSelection() like this:

import { createSelection } from 'bun-promptx'

function showMenu() {
    const selection = createSelection(
        [
          {
            text: 'skip',
          },
          {
            text: 'higher',
          },
          {
            text: 'lower',
          },
          {
            text: 'exit',
          },
        ],
        {
          headerText: `What would you like to do?`,
        }
    )

    return selection.selectedIndex
}

function init() {
    while (true) {
        const choice = showMenu() as number

        switch (choice) {
            case 0:
                console.log("First Choice")
                break
            case 1:
                console.log("Second Choice")
                break
            case 2:
                console.log("Third Choice")
                break
            case 3:
                console.log("Goodbye!")
                return
        }
    }
}

init()
