Kwalify YAML Validation - Use regexes in key names? - ruby

Question

I'm using Kwalify for schema validation. One part of the YAML document actually does want to allow for key names of a certain type in a mapping.
I see that Kwalify support regexes for the values in a mapping, but I see no such mention of support for using regexes in the keys in a mapping. Here's what I'd like to support validating:
test-element:
sub-element-1: test
sub-element-2:
element-with-pattern-1: test1
element-with-pattern-2: test2
So I don't know what some key names will exactly be in advance (shown here with the fake names "element-with-pattern-*", but I do know that they should correspond to a pattern defined by a regex.
Is this possible to validate using Kwalify?

Answer 1

To check this:
parent_key:
random_key1: url1
random_key2: url2
you should use "Default of Mapping", here is schema example:
type: map
mapping:
"parent_key":
type: map
mapping:
"=":
type: str

Answer 2

I do not believe it's possible given the current state of the code.
I'm actually in a similar situation, which I found out (the hard way) does not work well for validation in the Kwalify context. I've begun migrating away from flexible key names into a paradigm where I can specifically define the schema.
For example, I migrated this:
parent_key:
random_key1: url1
random_key2: url2
To:
parent_key:
- name: random_key1
url: url1
- name: random_key2
url: url2
With the latter syntax, you can validate like this:
"parent_key":
type: seq
sequence:
- type: map
mapping:
"name":
type: str
required: yes
"url":
type: str
required: yes
Within that context, you can add a pattern regex validators to either name or url that should allow you to achieve your goal.
