QGIS algorithm - Raise message

Description

QGIS Algorithm provided by QGIS (native c++) Raise message (native:raisemessage). Raises an information message. This algorithm raises an information message in the log. The message can be customized, and optionally an expression based condition can be specified. If an expression condition is used, then the message will only be logged if the expression result is true. A false result indicates that no message will be logged.

Usage

qgis_raisemessage(
  MESSAGE = qgisprocess:::qgis_default_value(),
  CONDITION = qgisprocess:::qgis_default_value(),
  ...,
  .complete_output = .complete_output_option(),
  .quiet = .quiet_option(),
  .messages = .message_option()
)

Arguments

MESSAGE

string - Information message. String value. field:FIELD_NAME to use a data defined value taken from the FIELD_NAME field. expression:SOME EXPRESSION to use a data defined value calculated using a custom QGIS expression.

CONDITION

expression - Condition. A valid QGIS expression string, e.g "road_name" = 'MAIN RD'.

further parameters passed to qgisprocess::qgis_run_algorithm()

.complete_output

logical specifying if complete out of qgisprocess::qgis_run_algorithm() should be used (TRUE) or first output (most likely the main) should read (FALSE). Default value is TRUE.

.quiet

logical specifying if parameter .quiet for qgisprocess::qgis_run_algorithm() Default value is TRUE.

.messages
