From: Dmitriy Anisimkov Date: Mon, 12 Aug 2019 09:01:53 +0000 (+0000) Subject: [Ada] New parameter Quiet for procedure GNAT.Command_Line.Getopt X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=4a2e9be1ac7c8f4c37b5deb4ce0b0f39925e56c9;p=gcc.git [Ada] New parameter Quiet for procedure GNAT.Command_Line.Getopt Getopt procedure is parsing the command line or set of strings. If the command line contains unknown switch than the Getopt prints error message to the console and raises the exception Invalid_Switch. The printing can be inappropriate in some cases. The new parameter Quiet allows avoiding console output. 2019-08-12 Dmitriy Anisimkov gcc/ada/ * libgnat/g-comlin.ads, libgnat/g-comlin.adb (Getopt): Add parameter Quiet. Need to do not output error messages to console. Invalid_Switch exception generation surrounded by an error message.
