Operator Mono and VIM

See below.

Trying to figure out how to render italics properly using operator mono and vim. Book Italic is the correct weight, if I set it as the normal font face, it renders perfectly but using it as the italic, and in combination with the Vimrc settings is no good. Any insights?

In alacritty config:

font:
  normal:
    family: OperatorMonoSSm
    style: Book

 italic:
    family: OperatorMonoSSm
    style: Book Italic

In my vimrc.

highlight Comment gui=italic cterm=italic
highlight htmlArg gui=italic cterm=italic

Some hours and googling later, I realized this has nothing to do with alacritty but nevertheless, it's working and this is my result.

Solution

Part 1 - the simple stuff

1. First off you'll need to purchase Operator Mono, Hoefler & Co customer support told me Operator Mono SSm is the way to go for sizes 9px to 18px.
2. Set it as the font within alacritty.yml - (reference above screenshot).
3. If you use NerdFonts, you'll need to patch Operator Mono using FontForge here.
4. Within vimrc or init.vim

   hi Comment gui=italic cterm=italic
   hi htmlArg gui=italic cterm=italic
   

Part 2 - the hard stuff

1. In home directory create new file xterm-256color-italic.terminfo with the following contents:

   xterm-256color-italic|xterm with 256 colors and italic,
   sitm=\E[3m, ritm=\E[23m,
   use=xterm-256color,
   

2. Compile it, with command: tic xterm-256color-italic.terminfo
3. Set it as the TERM within alacritty.yml - (reference above screenshot).
4. Restart alacritty. test with command: echo -e "\e[3mfoo\e[23m". It should output foo in italics.

Part 3 - tmux

1. Place the following within your tmux.conf:

   # enable true color support and italics
   set -g default-terminal "xterm-256color-italic"
   set -ga terminal-overrides ",xterm-256color-italic:Tc"
   

2. Restart tmux
