From d6c431859c6c0201e0668ed24a9f17cebf0a68f5 Mon Sep 17 00:00:00 2001 From: Ayman Bagabas Date: Fri, 8 Aug 2025 17:11:59 -0400 Subject: [PATCH] Support OSC 110, 111, and 112 for resetting colors This adds support for OSC 110, 111, and 112 escape sequences to reset the foreground, background, and cursor colors in the terminal. The changes include handling these sequences in the `strhandle` function of `st.c`, allowing applications to reset colors to their default values. The OSC sequences originated from Xterm control sequences and are now widely used in terminal applications and supported by many terminal emulators. For applications, this allows them to reset colors to default values without needing to know the colors beforehand.
