SUMMARY Python file syntax highlighting (in KDevelop) is definitely broken after the line containing the r'\\' expression. It was probably broken in the last framework release. STEPS TO REPRODUCE 1. Open KDevelop 2. Create a new file containing: class Any: def AnyMethod(self): pat = r'\\text' print ('still correct here') pat = r'\\' print ('broken here') 2. Select Python syntax for this file 3. Observe the result OBSERVED RESULT File syntax highlight is broken after the pattern r'\\' until the end of the python file EXPECTED RESULT Pattern r'\\' (or possibly r"\\") shall not break the syntax highlighting SOFTWARE/OS VERSIONS Linux/KDE Plasma: KDE Plasma Version: 5.22.4 KDE Frameworks Version: 5.84.0 Qt Version: 5.15.2 ADDITIONAL INFORMATION

Git commit e1c88423391c62448bea0009177228f90e20affa by Jan Paul Batrina. Committed on 30/07/2021 at 13:25. Pushed by cullmann into branch 'master'. Python: Fix r"\\" and derivatives In such cases, the last \ should not be interpreted as a line continuation escape. This regression was introduced by 14c8f9765843217b31c969670ebcf61b6bad446b and made more obvious by 90f5623611491ba665f1adeebff02916a73f37d6. New regression tests are added for most variants, e.g. rb"""\\""" M +4 -0 autotests/folding/test.py.fold M +4 -0 autotests/html/test.py.dark.html M +4 -0 autotests/html/test.py.html M +4 -0 autotests/input/test.py M +4 -0 autotests/reference/test.py.ref M +10 -1 data/syntax/python.xml https://invent.kde.org/frameworks/syntax-highlighting/commit/e1c88423391c62448bea0009177228f90e20affa
