if you install iterm2 on your macOS or linux,and you use oh-my-zsh,you can follow the steps:

# cd ~/.oh-my-zsh/plugins
// create incr folder
# mkdir incr
// download incr plugin
# wget
// authorize incr
# chmod 777 ~/.oh-my-zsh/plugins/incr/incr-0.2.zsh
# vim ~/.zshrc, and insert "source ~/.oh-my-zsh/plugins/incr/incr-0.2.zsh" in the "~/.zshrc",save and quit
// flush configuration
# source ~/.zshrc

Then you can use auto-completion for jcli, maybe you will find other commands can also use it
