Is there a way to check the format of a text field on a record? I am trying to set up an example that configures Java microservices, and would like to sanity check some of the values (i.e. that a bit of text matches a URL pattern and seems to generally match the conventions in place; that sort of thing).
The manual says that “The only text manipulation allowed is concatenation. Other than that,
Text values are opaque and there is no way to introspect them. For example, you cannot compare
Text values for equality, nor can you compute their length.” Is there another approach that would work well?
