Problem Description

I am using ZSH with auto-completion powered by zsh-completions (as provider) and fzf-tab (for fuzzy search).

However, the auto-completion feature of fzf-tab gets overridden by x-cmd under certain circumstances.

fzf-tab relies on the completion sources provided by zsh-completions, so I need to load zsh-completions before fzf-tab. Please see this for reference.

To control the loading order, I am using the plugin manager ZINIT. I manually load zsh-completions and fzf-tab as follows:

zinit light zsh-users/zsh-completions
zinit light Aloxaf/fzf-tab

However, when I load x-cmd, regardless of where I place the initialization statement for x-cmd (before or after zinit), fzf-tab gets overridden under certain circumstances.

To my knowledge, x-cmd seems to directly use the completions from zsh-completions in zsh. I suspect that this might cause zsh-completions to be loaded twice, resulting in fzf-tab becoming ineffective.

Alternatively, it could be that the completion mechanism implemented by x-cmd is overriding the completion mechanism of fzf-tab.

Steps to Reproduce:

1. Install x-cmd.
2. Use the following minimal zshrc configuration file and restart zsh:

# {{{ auto install and initialize zinit
ZINIT_HOME="${XDG_DATA_HOME:-${HOME}/.local/share}/zinit/zinit.git"
if [ ! -d "$ZINIT_HOME" ]; then
mkdir -p "$(dirname $ZINIT_HOME)"
git clone https://github.com/zdharma-continuum/zinit.git "$ZINIT_HOME"
fi
source "${ZINIT_HOME}/zinit.zsh"
# }}}

# auto download and load plugins
zinit light zsh-users/zsh-completions
zinit light Aloxaf/fzf-tab

# load x-cmd
[ ! -f "$HOME/.x-cmd.root/X" ] || . "$HOME/.x-cmd.root/X" # boot up x-cmd.

• Type cat and press the tab key, you will see fzf-tab's completion menu.
• Type cat - and press the tab key, you will see x-cmd's completion menu instead of fzf-tab's.
• Now type cat and press the tab key again, fzf-tab's completion menu will never show up again.

Expected Behavior

The completion menu of fzf-tab should always be displayed when press tab key.

Is there any way to disable x-cmd's autocompletion or any other way to fix this? 🙏
