https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=294499 Bug ID: 294499 Summary: [termcap] screen entry has so=\E[3m (italic) should be so=\E[7m (reverse video) Product: Base System Version: 14.3-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Some People Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: freebsd@gushi.org The screen entry in /etc/termcap has incorrect values for the standout mode capabilities: :se=\E[23m:so=\E[3m: \E[3m is the ANSI escape sequence for italic, not standout/reverse video. The correct values are: :se=\E[27m:so=\E[7m: This can be confirmed by noting that mr=\E[7m (reverse video) is correctly defined in the same entry — the right escape sequence was available but placed in the wrong capability. The screen-256color entry inherits from screen via tc=screen and is therefore also affected. The practical effect is that applications linking against base libtinfow display italic text where reverse video highlighting is expected. Confirmed with Alpine 2.26 inside a GNU Screen 5.0.1 session on FreeBSD 14. The fix is a one-line correction in the screen entry in /etc/termcap: :se=\E[23m:so=\E[3m: should be :se=\E[27m:so=\E[7m: Note that this entry ships in FreeBSD base and is present even on systems where the sysutils/screen port has never been installed. -- You are receiving this mail because: You are the assignee for the bug.home | help
