* vim displays reverse video instead of italics, while less displays italics
(or just regular text) instead of reverse. What's wrong?
* I don't see italics! Or less and vim show italics and reverse the wrong way round!
Screen's terminfo description lacks italics mode and has standout mode in its
place, but using the same escape sequence that urxvt uses for italics. This
means applications (like vim) looking for italics will not find it and might
turn to reverse in its place, while applications (like less) asking for
standout will end up with italics instead of reverse. To make applications
aware that tmux supports italics and to use a proper escape sequence for
standout, you'll need to create a new terminfo file with modified sgr, smso,
rmso, sitm and ritm entries:
GNU screen does not support italics and the "screen" terminfo description uses
the italics escape sequence incorrectly.
$ mkdir $HOME/.terminfo/
$ screen_terminfo="screen"
$ infocmp "$screen_terminfo" | sed \
-e 's/^screen[^|]*|[^,]*,/screen-it|screen with italics support,/' \
-e 's/%?%p1%t;3%/%?%p1%t;7%/' \
-e 's/smso=[^,]*,/smso=\\E[7m,/' \
-e 's/rmso=[^,]*,/rmso=\\E[27m,/' \
-e '$s/$/ sitm=\\E[3m, ritm=\\E[23m,/' > /tmp/screen.terminfo
$ tic /tmp/screen.terminfo
If default-terminal is set to "screen" or matches "screen-*", tmux will behave
like screen and italics will be disabled.
To enable italics, create a new terminfo entry called "tmux" (some platforms
may already have this, you can check with "infocmp tmux"):
$ cat <<EOF|tic -x -
tmux|tmux terminal multiplexer,
ritm=\E[23m, rmso=\E[27m, sitm=\E[3m, smso=\E[7m, Ms@,
use=xterm+tmux, use=screen,
tmux-256color|tmux with 256 colors,
use=xterm+256setaf, use=tmux,
EOF
$
And tell tmux to use it in ~/.tmux.conf:
set -g default-terminal "screen-it"
set -g default-terminal "tmux"
If your terminal supports 256 colors, use:
$ screen_terminfo="screen-256color"
instead of "screen". See the FAQ entry about 256 colors support for more info.
Also note that tmux will still display reverse video on terminals that do not
support italics.
If your urxvt cannot display italics at all, make sure you have an italics
capable font enabled, for example, add to ~/.Xdefaults:
If using urxvt, make sure you have an italics capable font enabled. for
example, add to ~/.Xdefaults:
urxvt.italicFont: xft:Bitstream Vera Sans Mono:italic:autohint=true
