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.
