From 1e41c667e6aa41b4d7dcf90559bd93ff330a3130 Mon Sep 17 00:00:00 2001 From: Trevor Gamblin Date: Wed, 21 Feb 2024 20:36:54 +0100 Subject: [PATCH] scripts/runqemu: fix regex escape sequences When invoking runqemu with Python 3.12, the following warning is encountered: |SyntaxWarning: invalid escape sequence '\.' This is because the interpreter scans the string before it is processed by the regex module, and it interprets the backslash as part of an escape sequence, but not a standard one. This will be registered as an error rather than a warning in future Python versions. To avoid the it, simply add an extra backslash so that Python doesn't misinterpret the string, while the regex parser still sees an escaped '.' character.
