Keywords Now() and Today() missing from the grammar

Open swan-verily opened this issue 1 year ago • 0 comments

Issue/Question

Now(), Today() and TimeOfDay are supported operators in CQL: https://cql.hl7.org/02-authorsguide.html, but they are not included in the Antlr4 grammar.

IIUC, Antlr4 listners can only listen for the defined keywords in the grammar. In this case, how does a CQL implementation parse and evaluate an expression like Now() + 7 days?
