emotty theme + emotty plugin + oh-my-zsh.sh = ☠

[Hi-Angel]

% cat ~/.zshrc              
export ZSH=/home/constantine/.oh-my-zsh
ZSH_THEME="emotty"
plugins=(git emotty themes)
source $ZSH/oh-my-zsh.sh
% zsh
emotty:4: bad math expression: operand expected at `/dev/pts/2...'
emotty:6: bad math expression: empty string

Deleting the oh-my-zsh.sh line fixes the error, as is changing the theme. zsh version 5.2.

UPD: writing in ~/.zshenv the setopt noglobalrcs in order to overwrite system configs (and because it is needed in order to work for "oh-my-zsh" in Archlinux) still leads to the same result, except that zsh ends up not even having a prompt (other themes I tried works).

I can reproduce this. The culprit seems to be this line in the emotty function of the emotty plugin:

(( tty = (${TTY##/dev/ttys} % ${#${=emotty}}) + 1 ))

Will research later.

I'm getting the same problem, any updates on this?

Confirmed also in an installation done today.

This turned out to be a really easy fix 😅.
