Convert object array to string array with comments

[alinjie]

Hello - yq noob here.

Say I have this input:

- id: 123
  name: "abc"
- id: 456
  name: "def"

And I want to produce an output array where each line consists of the name as the value and the id as a comment after the value, like so:

- abc # 123
- def # 456

How would I achieve this with yq?

TLDR:

yq 'with(.[]; . line_comment= .id | . = .name)

Explanation:

• .[] matches every array element
• with(.[] ; ...), sets the inner context to each array element, like a for loop
• . line_comment= .id sets the line comment of the current element to be the id value
• . = .name) sets the current element value to the name value.
