Class DoubleQuotedInterpolationOrError

java.lang.Object

org.ek9lang.compiler.phase1.DoubleQuotedInterpolationOrError

All Implemented Interfaces:

Consumer<EK9Parser.StringLitContext>

final class DoubleQuotedInterpolationOrError
extends Object
implements Consumer<EK9Parser.StringLitContext>

A double-quoted String holding ${ is an error (E07901): a double-quoted String is never interpolated, so "${count} items" prints those characters rather than the count. Writing it is almost always a habit from a language whose double quotes DO interpolate (Kotlin, Groovy, Dart, PHP, a shell) - and it compiled silently, surfacing only as wrong output, often much later.

The error names both backtick spellings - the interpolation and the literal text - from BacktickString, so either intent is one edit away. Checked on every String literal in the source, text-construct bodies included, but not on a directive's String: that is test metadata, never a program value.
