Cartesian product with a space

[tamanna2702]

I am trying the below as I need a space just after the colon:

---
meta:
  hosts:
    - a.example.com
    - b.example.com
    - c.example.com
  port: 8088

hosts: (( cartesian-product meta.hosts ":" " " meta.port ))

But Spruce seems to add single quotes to the results:

hosts:

• 'a.example.com: 8088'
• 'b.example.com: 8088'
• 'c.example.com: 8088'

Also, I tried the below :

---
meta:
  hosts:
    - a.example.com
    - b.example.com
    - c.example.com
  port: 8088

hosts: (( cartesian-product meta.hosts ": " meta.port ))

But I get the below error:

file1.yml: unmarshal []byte to yaml failed: yaml: line 8: mapping values are not → allowed in this context

This is intended. Cartesian product outputs a string, which in the context you’re generating requires quoting in the yaml file to remain a string, otherwise the output would be a list of yaml objects rather than strings, due to the colon-spca syntax you’re generating

In my use case, I do need a list of yaml objects using the cartesian product. That is why I need the space. Do you reckon this can be done somehow?

I don't believe there is anything that does this in spruce currently. This seems like it's a request identical to #212, so I'm going to close this as a duplicate, but if you want to submit a PR to enable this, it will be more than welcome 😄
