How to work with multiselect choices question?

[gi-dorio]

I am trying to scaffold a new app and I have a question for the user to select a bunch of components from a multiple choices question. Now, I've noticed that the answers to the questions can be used in the scaffold section as %yourkey.0%, %yourkey.1% etc based on how many choices you selected. My goal is to add the component only if it's selected, so my question is: is there any kind of IF statement for the scaffold or some other way to execute the command only if %yourkey.1% exist? Because right now referring to, for example, %yourkey.1% throws an error and blocks the process if it doesn't exist. Practical example. This is the question I ask:

yourkey:
  question: What fruits do you want to buy
  type: choices
  multiselect: true
  choices:
    - Apples
    - Oranges
    - Lemons
    - Papayas
    - Coconuts

I want the scaffolding section to create a directory for each of the selected options. So it would look something like this

scaffold:
  - mkdir %yourkey.0%
  - mkdir %yourkey.1%

How can I do this without knowing how many choices the user will make? Is there an IF statement or a way to check if, for example, %yourkey.1% exist without breaking the scaffold execution?

I'm sorry if it's a dumb question, but the docs are not clear at all on the use of values from questions

Hi @GiuseppeCSI

Multiselects are more suited when scaffolding actual files, there you have the full power of twig to iterate over arrays. Arrays are currently not supported for the scaffold-section.

You might try this workaround: Scaffold the actual script in a first step and then execute the script, e.g.:

The file setup.sh

#!/bin/bash

{% for folder in yourkey %}
mkdir {{folder}}
{% endfor %}

the actual scaffold-file:

questions:
  yourkey:
    question: What fruits do you want to buy
    type: choices
    multiselect: true
    choices:
      - Apples
      - Oranges
      - Lemons
      - Papayas
      - Coconuts
assets:
  - setup.sh

scaffold:
  - copy_assets(%rootFolder%)
  - bash %rootFolder%/setup.sh
  - rm %rootFolder%/setup.sh

(This is from the top of my head, and untested, so YMMV)

Hi, thanks a lot for the reply.

I've tried to work around the problem by using confirm questions and it works, but i tested your solution and it's definitely a lot more straightforward and avoids the redundancy of answering five yes/no questions. Since the workaround is so easy it's just a minor inconvenience, but is there any plan of supporting arrays in the scaffold section?

Also, speaking of questions, the documentation of the confirm question says it gives values 0 and 1 to the related key, but when I answer no it puts an empty space instead of a 0. Is this intended or a bug? Should I open a separate issue for this?

Thank you again

We can keep this issue as a reminder. I need to think of a way to transform the array into sth we can reuse in bash (as that is the underlying tool which executes the script)

Yes please.
