propertyNames validation is missing

[ypnos]

Currently it always returns true.

I cannot help out with this right now, this issue is to document the shortcoming so other users are aware.

please provide a mini example, we need it to confirm this issue

Example LUA code:

local schema = {
  type = 'object',
  propertyNames = {
    minLength = 4
  },
}
local model = {
  Foo = true
}
local options = {match_pattern=function () return true end, name="Test"}
local validator = JsonSchema.generate_validator(schema, options)
local isValid, errorStr = validator(model)
print(isValid, errorStr)

Expected output: false property name too short
Observed output: true nil

When using online validators, I receive the expected output with the following input.

JSON schema:

{
  "type": "object",
  "propertyNames": { "minLength": 4 }
}

JSON model:

{
  "Foo": true
}

@ypnos that is a todo feature, take a look at:

jsonschema/t/draft6.lua

Line 32 in f8d2f40

['propertyNames validation'] = { -- todo

jsonschema/t/draft7.lua

Line 32 in 09dc6ed

['propertyNames validation'] = { -- todo

welcome PR to fix it
