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?
