terminal spacemacs does not let TAB auto-complete shell commands (ansi/multi-term)

[jpstone]

Description

Using spacemacs in iTerm/Terminal.app, TAB does not auto-complete shell commands when in ansi/multi-term while in INSERT mode. If I enter normal mode, it completes fine. When in insert mode, it brings up helm Hmm.

This behavior does not exist for spacemacs GUI.

I think the behavior should be the same for terminal spacemacs as it is for the GUI.

Reproduction guide 🪲

• Start Emacs in a terminal
• Open ansi/multi-term
• Try to auto-complete shell commmands while in insert mode

Observed behaviour: 👀 💔

Instead of auto-completing, it brings up a helm menu.

Expected behaviour: ❤️ 😄

Auto-completion!

It's valid man tab completion does not work for me in ansi-term

[apmarshall]

Have we verified if this is a spacemacs configuration issue or something inherent to the difference between terminal’s and GUIs?

[lebensterben]

This is not a bug of emacs or spacemacs.

I'm using emacs 27.1 and spacemacs develop branch.
Tab completion is working for

• Both zsh and bash
• In xterm, gnome-terminal, and alacritty
• In ansi-term, and vterm

Check your own setup.
