From d26082357676a3c3843595dfe88a6c682b56e334 Mon Sep 17 00:00:00 2001 From: David Malcolm Date: Thu, 10 Oct 2019 16:57:30 +0000 Subject: pretty-print: support URL escape sequences (PR 87488) https://gist.github.com/egmontkob/eb114294efbcd5adb1944c9f3cb5feda describes an emerging standard for embedding URLs in escape sequences for marking up text output. This is supported e.g. by recent releases of GNOME Terminal. This patch adds support to our pretty-printing framework for emitting URLs. A followup patch uses this to add URLs to the pertinent documentation for the output of -fdiagnostics-show-option. gcc/ChangeLog: PR 87488 * common.opt (fdiagnostics-urls=): New option.
