Disjunctional pattern matching with Kwalify

Evert Mouw, 2014-09-23

The first space after the colon is needed and also will be ignored for the pattern matching.

So this key-value pair will not be recognized:

color:red

But this one will work normally:

color: red

The key is "color" and the value is "red" (without the space).

The enum operator does not validate empty values, even when the field is not required. This is a bug.

If you want to only validate a value when the whole value matches your pattern, and not only a part of it, then you need to pay close attention.

E.g., you want to match "ant" or "dinosaur" or "dino" or "ant, dino" or "ant, dinosaur" or "ant, dino*" ...

You specify this pattern in schema.yaml:

pattern: /[ ]|ant,[ ]*elek\w*|ant|dinosaur|dino/

Then this will be validated, because a part of it matches!

producten: ank, dinosaur

But this one will not be validated, because no part matches:

producten: ank

You need to make sure that the whole value, including the beginning (^) and the end ($), are matched.

pattern: /^$|^ant,[ ]*dino\w*$|^ant$|^dinosaur$|^elek$/

This works as expected.
