#16 Allowing Regex Matches for Key Mappings

[Eric Myllyoja]

Say I have a YAML use case which demands the following structure, which does not allow for sequences:

test-element: 1
element-with-pattern-1: 0x-test1
element-with-pattern-2: 4x-test2
element-diff-pattern-1: 971
element-diff-pattern-2: 382
element-diff-pattern-3: 882

element-with-pattern and element-diff-pattern may appear in unknown quantities, but otherwise must follow the specified structure, with a standard name and validated data types within.

I know the exact name and data format of the first value, and can write a Kwalify statement for it, but for the other 5 values, I do not know exactly how many values there may be, and defining a default schema does not work because the first set has a string with a specific format while the second stirng has a numeric type.

Ideally something like below could be used:

"element-with-pattern-([0-9])+":
  type: string
  required: yes
  pattern: /[0-9]x-test[0-9]/

This is a very common use case experienced by many users, as shown in the below issues:
