trait FrontEnds extends AnyRef
Abstract Value Members
abstract def abort(pos: blackbox.Context.Position, msg: String): Nothing
Abruptly terminates current macro expansion leaving a note about what happened. Use enclosingPosition if you're in doubt what position to pass to pos.
abstract def echo(pos: blackbox.Context.Position, msg: String): Unit
For sending a message which should not be labelled as a warning/error, but also shouldn't require -verbose to be visible. Use enclosingPosition if you're in doubt what position to pass to pos.
abstract def error(pos: blackbox.Context.Position, msg: String): Unit
Emits a compilation error. Use enclosingPosition if you're in doubt what position to pass to pos.
abstract def hasErrors: Boolean
abstract def hasWarnings: Boolean
abstract def info(pos: blackbox.Context.Position, msg: String, force: Boolean): Unit
Emits an informational message, suppressed unless -verbose or force=true. Use enclosingPosition if you're in doubt what position to pass to pos.
abstract def warning(pos: blackbox.Context.Position, msg: String): Unit
Emits a warning. Use enclosingPosition if you're in doubt what position to pass to pos.
