In a presentation at Docker Con 2022, Shy Ruparel showed his iTerm2 terminal with an awesome completion/suggestion function. It shows command suggestions in a menu while typing, without pressing TAB key. It is also able to capture and show new possibilities dynamically, for example, the newly pulled 'fedora' image was shown as a new suggestion for 'docker run' command.
I did some researches on the Internet but couldn't find anything similar. Does anyone know what completion/suggestion software was use?
You can see it in action here: https://docker.events.cube365.net/dockercon/2022/content/Videos/ba325a70-52da-4d54-a382-82cb6b7b718d, at 00:28:31.
zsh
is not a terminal, it's a shell, but it can or can be configured to tell a terminal to display its completions in various forms. That particular form is not something that comes builtin inzsh
AFAIK, and it seems it needs some ability that is specific to one terminal emulator in particular as I've never seen a terminal that lets applications render menus like that.
