Watch the video and look at his github pages, they're excellent.
I have the following note stored on my HD:
We can have italics in the terminal.
This works in iTerm as well as Terminal.
We have to adapt the terminfo database to tell it to display italics.
Create a plain text file which contains the following:
xterm-256color|xterm with 256 colors and italic,
Save it as
Then execute the following command:
tic -o ~/.terminfo xterm-256color.terminfo.txt
This will create a
~/.terminfo/some_arbitrary_number/ directory, and inside that directory is a
What it does according to the manpage:
The command tic translates a terminfo file from source format into com-
piled format. The compiled format is necessary for use with the
library routines in ncurses(3X).
The results are normally placed in the system terminfo directory
/usr/share/terminfo. There are two ways to change this behavior.
First, you may override the system default by setting the variable TER-
MINFO in your shell environment to a valid (existing) directory name.
Secondly, if tic cannot get access to /usr/share/terminfo or your TER-
MINFO directory, it looks for the directory $HOME/.terminfo; if that
directory exists, the entry is placed there.
Libraries that read terminfo entries are expected to check for a TER-
MINFO directory first, look at $HOME/.terminfo if TERMINFO is not set,
and finally look in /usr/share/terminfo.
-o dir Write compiled entries to given directory. Overrides the TER-
MINFO environment variable.
So with the given command we are writing a new terminfo entry in the hidden
~/.terminfo directory. It takes the capabilities of the existing xterm-256color entry (from
/usr/share/terminfo/) and adds italics mode to it.
To check that the terminal does the right thing:
I guess at the moment most vim terminal colorschemes don't set italic as a style. To check this do:
:hi Comment if the reply contains
cterm=italic you're done.
If not add
highlight Comment cterm=italic to your vimrc (below setting your colorscheme).
Addendum for tmux
tmux uses its own terminfo files, they also need to be updated to use italics.
- create a
tmux.terminfo.txt file which contains
tmux|tmux terminal multiplexer,
- create a
tmux-256color.terminfo.txt file which contains
tmux-256color|tmux with 256 colors,
and run the tic command.
tic -o ~/.terminfo tmux-256color.terminfo.txt
tic -o ~/.terminfo tmux.terminfo.txt
